In 2024, the City was awarded an Energy Innovatfon Grant from the Public Service Commission of Wisconsin to support the creatfon of a Comprehensive Energy Plan. This initfatfve builds on previous high-level sustainability planning but focuses more deeply on the buildings that make up the City’s operatfonal footprint. Oshkosh owns and operates 127 standalone facilitfes, including fire and police statfons, public works buildings, wastewater treatment plants, a public museum, and a library. These facilitfes are central to the City’s services, but they also account for a significant portfon of municipal energy use and greenhouse gas emissions. Recognizing this impact, City leaders determined that a building-focused energy plan is essentfal to: • Meet carbon reduction targets through efficiency and renewable energy adoptfon. • Reduce operational costs and reinvest savings into clean energy improvements. • Integrate energy upgrades with long-term capital planning, ensuring coordinated, cost-effectfve investments. The Energy Plan is both a technical roadmap and a call to actfon, helping Oshkosh align its energy use with community values of stewardship, resilience, and fiscal responsibility. Intent of the Plan The purpose of this Comprehensive Energy Plan is to establish a clear, actfonable strategy for reducing energy use, adoptfng renewable energy, and decarbonizing municipal operatfons. Specifically, the plan is designed to: • Benchmark municipal building performance and provide tools to monitor progress over tfme. • Assess solar energy potential across all City facilitfes, with detailed modeling for the most promising sites. • Prioritize actions that lower operatfng costs, reduce greenhouse gas emissions, and build financial capacity for further clean energy investment. • Deliver a practical implementation roadmap aligned with Oshkosh’s goals, capital planning cycles, and available funding sources. Introduction 1: GHw = 1,000,000 kWh Click here to return to TOC CITY OF OSHKOSH ENERGY PLAN | 1-2 Development of the Energy Plan effort included: Assessments The assessment phase was focused on collectfng data on the City’s facility portiolio and studying the potentfal for on-site renewable energy and estfmatfng the order-of-magnitude energy efficiency. The assessments included: Building Information Collection Collectfon of facility characteristfcs including energy systems, age, size, and roof details. Energy Benchmarking Creatfon of ENERGY STAR Portiolio Manager accounts for each facility, enabling benchmarking against natfonal peers. Through benchmarking, buildings can be identffied and prioritfzed based on likely opportunitfes for increased energy efficiency and greenhouse gas reductfon potentfal. Solar Site Reviews: Conductfng a high-level review of all City facilitfes to antfcipate the likely capacity and appropriateness for cost- effectfve solar installatfon. Detailed Solar Feasibility and Financial Modeling Detailed solar feasibility assessments and financial modeling was conducted for 33 selected buildings. The solar feasibility assessment is designed to evaluate the potentfal for solar photovoltaic (PV) systems on municipal sites, with the aim of enabling each site to generate as much electricity as it consumes annually. To support decision- making, a preliminary cost opinion and a 30-year projectfon of energy generatfon and value have been prepared for each site. These estfmates are high-level and based on natfonal cost averages adjusted for local conditfons, market data, and utflity rate structures, though they should be validated before detailed planning proceeds. The assessment process involved both remote and site-specific reviews to identffy opportunitfes and barriers, such as existfng or future building conditfons and obstructfons that may limit solar performance. For each site deemed feasible, concept designs were developed that outlined system layout, tflt, orientatfon, and preliminary equipment selectfons. Performance modeling incorporated weather data, site-specific shading, and technical assumptfons to estfmate annual energy productfon and efficiency metrics. Each site report provides a comprehensive overview of the solar concept design, including maps of array placement, productfon values by month and year, loss factors, and preliminary assumptfons about electrical and mechanical integratfon. The reports also contain detailed constructfon cost estfmates, bills of materials, and year- by-year financial projectfons of system performance over a 30-year period. Together, these analyses offer communitfes a clear picture of solar PV opportunitfes, expected savings, and the scale of investment required to pursue carbon reductfon and long-term energy resilience. Action Identification and Energy Roadmap Development Based on the findings from the assessment phase, the planning team created recommended strategic goals and a list of detailed actfons to guide municipal operatfons in support of advancing the City’s energy objectfves. The development of roadmap actfons was aided by a best practfce review informed by paleBLUEdot’s ACTIONFinder tool, which encompasses over 4,500 actfons and strategies from regional and natfonal municipal energy, sustainability, and climate actfon plans. The final strategic goals and actfons offer a roadmap for the City of Oshkosh to achieve carbon reductfon, energy efficiency, and long-term operatfonal cost savings goals. Planning Process 1-3 | CITY OF OSHKOSH ENERGY PLAN This Energy Plan is intended to serve as a practfcal, long-term guide for Oshkosh’s municipal operatfons, ensuring that every building-related energy decision contributes to the City’s goals of cost savings, resilience, and carbon reductfon. The plan is organized through an “Energy Roadmap” focused on the following goals: These goals are supported by strategies and actfons. Strategies are specific statements of directfon that expand on the energy efficiency, renewable energy, and GHG reductfon goals and guide decisions about future public policy, community investment, and actfons. Actions are detailed items that should be completed in order to carry out the vision and strategies identffied in the Roadmap. The Plan GHG emissions (metric tons) reduced electrificatfon and fuel switching increased renewable electricity (on-site + purchased) increased Natural Gas consumptfon reduced Electricity consumptfon reduced CITY OF OSHKOSH ENERGY PLAN | 1-4 Implementing the strategies included in this plan will result in: • Decreasing negative environmental impacts of City of Oshkosh operations. • Reducing reliance on fossil fuel sources and transitioning towards green, renewable energy. • Long-term greenhouse gas (GHG) emission reductions. • Developing infrastructure and building projects that include sustainability features from the start. • Protecting natural resources and ecosystems. Modeled Savings by 2035 Greenhouse Gas (GHG) Reductions The long-term GHG emission reductfon potentfals of the strategies and actfons included in this plan have been modeled based on projected energy and fuel reductfons. From this modeling, we know that with the successful implementatfon of this sustainability plan, the City of Oshkosh operatfonal annual GHG emissions are projected to drop 9,417 metric tons below 2024 levels by 2035 and 15,071 metric tons by 2040. These reductfons are equal to a 62.5% reductfon in annual GHG emissions by 2035 and a 100% reductfon in annual GHG emissions by 2040.

See Appendix for a detailed illustratfon of how cumulatfve costs and savings are determined. 2-1 | CITY OF OSHKOSH ENERGY PLAN Click here to return to TOC Reducing energy and water usage and minimizing waste generatfon is essentfal for an organizatfon's sustainability goals. This approach of doing more with less can lead to cost savings and increased efficiency while achieving environmental sustainability. By conserving resources through decreased energy and water usage and minimizing solid waste, organizatfons can save on utflity and disposal costs. Prioritfzing these practfces demonstrates an organizatfon's commitment to environmental responsibility, maximizes their resources and saves money while achieving climate and sustainability goals. Establishing consumptfon baseline levels is crucial for developing reductfon targets and tracking progress over the long-term. Energy Consumption The City of Oshkosh’s buildings total 981,389 sf. In 2024 the City’s operatfons consumed 44,930,842 kWh of electricity, and 584,822 therms of natural gas. When measured based on Energy Use Intensity (total KBTU of energy / total building square footage) the City’s average energy use intensity totaled 42.6 for electricity and 54.5 for natural gas.1 Benchmarking City of Oshkosh Facility Energy Use and Calculating Potential Savings1 The chart on the following page reviews each City of Oshkosh facility’s reported energy use against natfonal averages for similar facilitfes. These numbers can then be used to estfmate the potentfal energy reductfon potentfal for facilitfes which consume more than the natfonal average for similar facilitfes. The estfmated energy reductfon potentfal assumes energy improvements to each subject facility result in the facility operatfng at the natfonal average when completed. This review highlights energy, cost, and GHG reductfon potentfal for each facility, based on matching natfonal averages. While it provides a rough estfmate, specific targets require detailed energy audits. Energy Audit Prioritization Based on the energy benchmarking review, sites were prioritfzed for suggested detailed energy audits as follows: Priority 1 Sites have energy use over 150% of the natfonal average and are antfcipated to have detailed energy audits result in potentfally significant energy efficiency opportunitfes. Priority 2 Sites have energy use at 100% to 150% of the natfonal average and are antfcipated to have detailed energy audits result in at least moderate energy efficiency opportunitfes. Priority 3 Sites currently perform above the natfonal average energy consumptfon and may have energy efficiency opportunitfes identffied in a detailed energy audit. 1 EUI averages exclude the Wastewater Treatment Plant, Water Filtratfon, and Water Distributfon due to EUI calculatfons for those facilitfes being based on per-gallon flows rather than per square foot as all other facilitfes are calculated.

Each site was evaluated for roof layout, shading, obstructions, and estimated annual sunlight (insolation) to determine suitability for cost-effective solar PV installations. Buildings with strong potential advanced to detailed solar and financial modeling (see Solar Feasibility Assessments). The analysis used satellite imagery, NREL data, Project Sunroof estimates, and other sources. Evaluation metrics included annual sunlight hours, roof configuration, and presence of roof or solar obstructions. The following categories were applied to each metric. Roof Configuration Optimum: The best possible roof layout and orientation for solar panel installation and performance. Suitable: Roof layout should adequately support solar panel installation and performance, though some limitations may exist. Challenging: Roof layout should support solar panel installation to a degree, however, roof layout, orientation, materials, or other design features limit the overall capacity or may impact cost-effectiveness of installation. Inadequate: Roof layout is not likely to accommodate a cost-effective solar installation. Roof Obstructions (rooftop equipment or structures) None: The roof appears to have no equipment or structures which would limit or impact solar installations. Low: The roof has some equipment or structures, however, their extent or locations are not anticipated to significantly impact solar installations. Moderate: Roof equipment or structures are present which are anticipated to limit solar installation potential. High: Roof equipment or structures significantly restrict or eliminate solar installation potential. Solar Obstructions (shade and shadows from building elements or adjacent trees and structures) None: No building elements or adjacent trees or structures are anticipated to limit solar performance. Low: Building elements, trees, or adjacent structures are present but are not anticipated to significantly limit solar performance. Moderate: Building elements, trees, or adjacent structures are present and are anticipated to limit solar performance on portions of roof. High: Building elements, trees, or adjacent structures are present and are anticipated to significantly limit solar performance. Preliminary Prioritization Based on the evaluations for each metric, sites were prioritized for further study as follows: Priority 1 Sites are anticipated to support cost-effective solar installations and were included in the detailed PV and financial modeling effort (see Solar Feasibility Assessments). Priority 2 Sites may support reasonably cost-effective solar installations, or limited cost-effective solar installations and were included in the detailed PV and financial modeling effort (see Solar Feasibility Assessments). Priority 3 Sites are not anticipated to support cost-effective solar installations within the current market or are capable of supporting very limited solar arrays and were not included in the detailed PV and financial modeling effort.

CITY OF OSHKOSH ENERGY PLAN | 3-2 4-1 | CITY OF OSHKOSH ENERGY PLAN Click here to return to TOC The goal of the solar feasibility assessment effort is to explore the general potential for solar pv on each site with the goal of achieving a site which generates as much electricity within a year as it consumes within the same timeframe. Prior to proceeding further with the planning of any rooftop solar pv array, an assessment of the structure of each building included in this section should be conducted. A preliminary opinion of cost as well as a preliminary 30 year energy generation and value projection have been developed for each site. Costs are intended to illustrate Order of Magnitude and are preliminary in nature. Cost unit prices are based on national averages provided by the National Renewable Energy Laboratory, modified using local construction cost indices as well as market outreach to collect current supply chain considerations. The 30 year value projections include estimates of base and solar buy back electric rates based on information available from the subject utility. Electric rates for each building, as well as the rate tariff under which the site building is metered should be validated prior to proceeding further with the planning of any site. Solar Feasibility Assessment Approach The detailed Solar Feasibility Assessment for each of the sites can be found on the following pages. The Solar Feasibility Assessment included a review of overall solar feasibility as well as development of solar pv concept designs for each recommended site. These efforts consisted of: Determining the feasibility of solar energy: • Conducting remote review of each recommended site using satellite data of each subject building and site. • Identifying current and planned future building and site conditions which create impediment to solar pv installations. • Identifying and record solar obstructions impacting potential solar pv performance. Solar PV Concept Design. • Creating concept design(s) for building and/or site solar PV array at each recommended site. Concept designs include overall array configuration, tilt, azimuth, and preliminary panel and inverter selections. • Modeling annual solar pv performance based on detailed design components, historic local weather data, and site-specific solar obstructions. • Creating a solar pv concept design report for each recommended site. Reports include: • Summary metrics including energy production, performance ratio, and kWh/kWp; Locations of array segments shown on map; • Monthly and annual production values; • System loss factors and detailed loss tree; records of condition set assumptions; • Preliminary bill of materials; • Preliminary electrical concept design assumptions; • Preliminary Mechanical layout assumptions; • Detailed concept plan/layout; • Detailed construction cost estimate; • 30 year energy production, value, and cost savings projections year-by-year. Solar Feasibility Assessments CITY OF OSHKOSH ENERGY PLAN | 4-2 The following are considerations building owners should be aware of before “going solar.” How Solar PV Works Solar electricity is created using Solar Photovoltaic panels, or Solar PV for short. The word photovoltaic, or PV, comes from the process of converting light (photons) to electricity (voltage), which is called the PV effect. The key to a solar PV panel is the semiconductor material. Solar PV semiconductors combine properties of some metals and properties of insulators - making them uniquely capable of converting light into electricity. The simple explanation of how solar panels create electricity is that as sunlight (specifically UV light) strikes the semiconductor materials in the PV cell, the energy knocks loose electrons. Those electrons then move back and forth between semiconductor plates producing an electric current. Structural Capacity for Rooftop Arrays The assessments included in this report do not include assessments of rooftop structures to accept the additional loading of a solar PV array. Projects which anticipate rooftop arrays should have a preliminary structural assessment to confirm solar PV loading can be adequately handled by the existing structure. The weight of a PV system varies based on the panel and racking systems selected. For rooftop arrays, two racking system configurations are common: flush or tilted mechanically fastened racking types (which require roof penetrations, or clamp on standing seams); and ballasted racking types (which use weighted components to make the array stationary through gravity and typically do not require roof penetrations). A reasonable “rule of thumb” for solar PV array assembly structural loading is 2-4lbs per square foot for typical flush or tilted racking systems, or 5-9lbs for ballasted racking systems. 4-3 | CITY OF OSHKOSH ENERGY PLAN Financial Incentives Renewable Energy Certificates Renewable Energy Certificates (RECs), also known as Renewable Energy Credits, are issued for each megawatt-hour of renewable electricity added to the grid, serving as an accounting tool for renewable energy in the mixed-source power grid. RECs represent the environmental benefits of renewable energy, with only the final consumer of the REC having the right to claim these benefits. Once a REC is sold, the owner of the renewable energy generator relinquishes the claim to using renewable electricity – regardless of where the electrons flow. For City of Oshkosh clean energy goals, it will be critical for the City to retain all REC’s associated with any renewable energy generation, purchase, or subscription entered into. Alternatively, if REC’s are not retained for any reason, the City should procure REC’s equal to the electricity consumed from sources where the RECs are not retained. CITY OF OSHKOSH ENERGY PLAN | 4-4 Investment Tax Credit (ITC) for Government Entities The Inflation Reduction Act (IRA) passed in 2022 made a number of modifications to the Investment Tax Credit (ITC) available for solar PV installations. The two most significant are the extension of benefits through 2035 and the establishment of the “Direct Pay Option” for tax exempt organizations such as local and regional government entities. Beginning January 1, 2023, tax-exempt organizations—such as non-profits, states, municipalities, Indian Tribal governments— can receive a refund from the IRS for tax credits on projects placed in service after 2022. In July 2025 the “Big Beautiful Bill” was passed which repealed the ITC credits beginning January 1, 2026. Consequently, only projects completed by December 31st, 2025 will qualify for the ITC under current legislation. https://www.energy.gov/eere/solar/federal-solar-tax-credits-businesses Peak Shaving and Demand Charges Customers pay for electricity in one of two ways: consumption, measured in kilowatt-hours (kWh); and demand, measured in kilowatts (kW). Most residential customers only pay for consumption. Many commercial and government customers are on demand charge tariffs and they pay for both demand and consumption. With demand charge billing the customer pays for the highest power load reached – the peak demand. Peak demand is defined as the highest average load during a specific time interval (usually 15 minutes) in each billing cycle. Utilities use demand charges to help recover costs associated with running power plants or buying power from other utilities on the energy spot market. Demand charges also help utilities recover transmission costs to customers with large energy needs. Not all utility customers are on demand charge tariffs, but for large consumers of electricity those charges can be a significant part of a monthly utility bill. Utility customers who do have demand charge tariffs can see a large portion of their monthly electric bill going towards demand charges (30% to 70% is not uncommon). The most effective way to manage utility costs for customers with demand charges is a practice called peak shaving. Peak shaving involves proactively managing overall demand to eliminate short-term demand spikes, which set a higher peak. This process lowers and smooths out the electric use “curve” and reduces peak loads, which reduces the overall cost of demand charges. Solar arrays with a battery energy storage system allows customers to peak shave. Battery energy storage systems are dispatchable; they can be configured to strategically charge and discharge at the optimal times to reduce demand charges. Sophisticated control software with learning algorithms differentiates battery energy storage systems from regular batteries. These algorithms learn a customer’s load profile, anticipate peak demand, and switch from the grid to batteries when needed most - reducing the customer’s peak load and saving on demand charge costs. State of Wisconsin Incentives Focus on Energy renewable rewards Wisconsin provides rebates to reduce the expenses of setting up solar panel systems. The rebates differ by customer category: up to $500 for Residential, $50,000 for Commercial, $60,000 for Agricultural, and $81,000 for Special sectors like nonprofits, schools, government, and Native American tribes and nations.1 Wisconsin Solar Tax Exemptions Wisconsin offers two sales tax exemptions for renewable energy technologies, including Solar Water Heat, Solar Space Heat, Solar Thermal Process Heat, and Solar Photovoltaics. This means there's no sales tax when installing solar panels in Wisconsin homes or businesses. Additionally, the added value from biogas, synthetic gas energy systems, solar energy systems, or wind energy systems is exempt from general property taxes, irrespective of whether the equipment is classified as real or personal property. 1: Focus on Energy: https://focusonenergy.com/financial-resources ; https://www.focusonenergy.com/residential#program-renewable-energy 4-5 | CITY OF OSHKOSH ENERGY PLAN Energy Storage and Resilience On-site solar PV can offer opportunities to increase the energy resilience for building. If a building has solar panels installed on site they will continue to generate electricity during power outages, as they do every day because the panels still absorb sunlight and solar energy. However, if the system is grid-tied, and the building does not have energy storage connected to the solar array, the building will not be able to use that energy during a power outage. Code requires solar systems which are grid-tied to shut down during a power outage for safety reasons. If backup energy storage, or electrical demand charge reductions are of interest for the site, designers should anticipate the potential for future battery storage. Battery technology has experienced some refinement and advancement in recent years - technological evolution should be expected to continue for energy storage systems. Consequently, the future space needs for battery banks may only be able to be estimated at best. Additionally, different battery systems, like lead acid, or lithium ion batteries, have different configurations and space requirements. With these considerations, the designer should still identify the future battery bank location and provide adequate space for the future battery bank. A reasonable rule of thumb would be to provide a 4’x4’ space for every 20 Kwh of electrical storage capacity anticipated. The space should be located adjacent to the wall receiving future batteries. Project Delivery Options This report assumes all solar pv systems are direct purchase of the Building Owner. Regional solar developers may provide services to building/site owners through alternative project delivery options such as Solar Lease Agreements, Power Purchase Agreements. These alternative delivery methods use 3rd party entities for one or more aspect of the procurement and ownership of the solar array and tax benefits. 3rd party project delivery methods frequently have a solar array purchase opportunity at a future date such as in year 7, year 10, or year 20. For the County, the advantage of a 3rd party project delivery is the ability to leverage project savings from tax benefits which are not available to non-profit entities such as Modified Accelerated Cost Recovery System (MACRS). Note, however, as of 2023, non-profit entities may be eligible for the Direct Payment Option for the ITC ( see “Investment Tax Credit (ITC) for Government Entities“) Most Solar Lease Agreements are designed so that the 3rd party, or the power company, retains the RECs produced by a solar array. As such, any entity that is motivated to claim use of renewable energy or to leverage a reduction in their operating greenhouse gas emissions would typically not be capable of making such claims under these traditional 3rd party delivery structures. It may be possible, however, to negotiate a project delivery similar to a Solar Lease in which the site owner could retain the REC’s generated by the project. (see “Renewable Energy Credits” for more). Note, the legal support for solar lease agreements has not yet been fully clarified in Wisconsin.1 Which Approach is Best? Purchasing a solar panel system with cash (or loan) is your best option when you… •Want to maximize long-term value. •Are eligible to reduce your federal and state tax liability through the federal investment tax credit. •Are a business, and can realize tax benefits by treating the solar panel system as a depreciable asset. •Want to increase the market value of your home by installing a solar panel system. A solar lease PPA is your best option when you… •Want to eliminate up-front costs. •Want to avoid the responsibility of maintenance or repairs for a solar panel system. •Are ineligible for federal or state investment tax credits from your investment in a solar panel system. •Do not want to wait until the following year to receive the financial benefits of tax credits. 1: Associated Builders and Contractors, Wisconsin: https://www.abcwi.org/wisconsin-contractor-blog/third-party-solar-arrangements-remain-in-legal-limbo/ CITY OF OSHKOSH ENERGY PLAN | 4-6 Summary of Solar Feasibility The table on the following page summarizes the results of the detailed site solar feasibility assessments for each of the sites. The recommended site priority levels include: • Priority 1—Recommended installation within 0-2 years; Feasibility assessment for these sites indicate likely good or very good return on investment (ROI) and benefits for the site. • Priority 2—Recommended installation within 0-5 years; Feasibility assessment for these sites indicate likely good ROI. Proceeding with these sites within a multi-site procurement approach in conjunction with Priority 1 sites may increase potential ROI and should be pursued if initial funding or project capacity exists. Alternatively, these installations may benefit from improved market conditions such as improved supply chain considerations and system cost per watt. • Priority 3—Installations likely to benefit waiting 5-10 years before proceeding; installations may benefit from improved market conditions such as improved supply chain considerations and resulting reduced panel cost per watt. • Priority 4—Solar PV not currently recommended. 4-7 | CITY OF OSHKOSH ENERGY PLAN Summary of Solar Feasibility Government Facilities PV Nameplate Capacity (KW DC) PV KWH % of Consumed Estimated Installation Cost (Financed) Financed Payback1 (years) Value To Cost Ratio ( x : 1.0) Recommended Site Priority City Hall 53.6 9.1% $145,206 13.5 2.22 1 Fire Station #152 80.4 58.3% $183,434 11.3 2.66 1 Fire Station #18 58.8 106.6% $160,708 15.4 1.95 2 Fire Station #19 76.0 100.2% $186,033 13.5 2.22 1 Safety Building - Police Station2 157.2 18.3% $309,298 10.5 2.86 1 Police Evidence Garage 8.0 125.2% $29,483 25.4 1.18 4 Sawyer Street Storage2 28.0 110.1% $88,174 18.0 1.67 2 Facilities Maintenance - Cold Storage2 23.6 116.6% $76,332 17.6 1.71 2 Grand Theater 41.2 20.0% $120,103 14.9 2.01 1 Oshkosh Center & Walk Way 181.0 10.5% $356,137 10.0 3.00 1 Electrical/Bus Garage2 124.8 89.1% $246,065 10.5 2.9 1 Transit Center 35.2 110.7% $106,258 15.4 1.9 2 Public Works Field Ops Facility 576.4 111.0% $1,080,478 9.5 3.2 1 Senior Center North Building2 61.6 107.6% $158,904 12.8 2.3 1 Senior Center South Building 90.0 108.4% $191,843 10.8 2.8 1 Parks & Forestry Building 128.8 108.5% $235,916 9.9 3.0 1 Riverside Cemetery2 9.2 111.6% $33,357 20.1 1.5 3 Lakeshore Park - Four Seasons Pavillion 56.4 49.4% $150,223 14.3 2.1 1 Pollock Community Water Park 75.2 44.8% $177,720 12.1 2.5 1 Wastewater Treatment Plant (WWTP) 800.8 12.6% $1,469,494 9.2 3.3 1 Water Filtration Plant2 654.4 19.8% $1,279,652 9.9 3.0 1 Water Distribution Center2 92.4 112.0% $193,513 11.2 2.7 1 Menomonie Kiwanis Park Shelter 3.2 125.1% $13,535 39.1 0.8 4 Menomonie Park Maintenance Garage 5.2 119.8% $27,021 36.6 0.8 4 Menomonie Reetz Comfort Concession 17.6 113.6% $56,822 20.6 1.5 3 Menomonie Train Station Concessions 6.8 53.3% $24,591 24.2 1.2 3 Menomonie Zoo Maintenance Building 10.8 25.5% $36,936 18.4 1.6 2 South Park 6.4 122.4% $25,847 27.6 1.1 4 Red Arrow Park 0.8 132.5% $5,171 -35.6 -0.8 4 Fugleberg Boat Launch 3.2 114.3% $13,069 39.9 0.8 4 Stevens Park 1.6 119.7% $7,823 236.1 0.1 4 Abe Rochlin Park 13.6 69.9% $47,176 19.7 1.5 3 Riverwalk - South Shore West Zone 9.6 94.8% $28,345 23.9 1.3 3 1: Payback is calculated using a Wisconsin Public Service recommended value per kWh generated by the solar array and assumes 20% of the array cost is paid at time of project completion and 80% is covered through a loan with 7 year term and 5% interest. 2: If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation.

These goals inform future policies, municipal operatfons, and investments. Each goal is supported by specific actfons that outline practfcal steps to achieve the plan’s vision and strategies. The City’s Energy Use Most of the City’s municipal energy consumptfon comes from electricity and natural gas used in its facilitfes. In 2024, across more than 981,000 square feet of buildings, the City used 18,889,107 kWh of electricity and 584,882 therms of natural gas. Excluding the Wastewater Treatment Plant, Water Filtratfon Plant, and Water Distributfon Facility, the average energy use intensity (EUI) of this portiolio is 75.4 (kBTU per square foot). This energy powers lightfng, heatfng, cooling, and office equipment such as computers, printers, and monitors. Reducing energy use and transitfoning away from fossil fuels represent the most significant opportunitfes for lowering municipal emissions. Beyond reducing GHGs, these strategies will also cut costs, increase energy independence, and improve the health and comfort of City employees. Benefits of Implementing the Roadmap Municipal operatfons can see many benefits from adoptfng energy-efficient and sustainable practfces, including; • Lower Costs: Reducing energy use decreases utflity expenses, allowing more resources to support community services. • Demonstrated Leadership: By prioritfzing sustainability, municipalitfes set an example that can motfvate residents and local businesses. • Climate Actfon: Implementfng green building strategies helps cut greenhouse gas emissions and supports climate goals. • Health Benefits: Efficient buildings often provide cleaner indoor air, contributfng to better public health. • Stronger Resilience: Sustainable facilitfes are more capable of withstanding extreme weather and other climate- related challenges. Energy Roadmap 2025 2035 Goals 2040 Goals Sector Goals GHG emissions (metric tons) reduced electrificatfon and fuel switching increased renewable electricity (on-site + purchased) increased 18.9 GWh1 585,000 therms N/A N/A 15,071 MT 16.6 GHh1 515,000 therms 8.3 GHh1 20% of heatfng 5,654 MT 15.1 GHh1 468,000 therms 15.1 GHh1 40% of heatfng 0 MT Natural Gas consumptfon reduced Electricity consumptfon reduced 1: GHw = 1,000,000 kWh 1: GHw = 1,000,000 kWh Strategies show how we achieve our energy goals. Actfons outline steps the City can take to support strategies. Strategy Metrics indicate how we can measure our progress. On the following pages: How We Get There CITY OF OSHKOSH ENERGY PLAN | 5-2 Energy Roadmap Strategy E 1 Improve total City of Oshkosh building and site Energy Use Intensity (EUI) by 12% by 2035 and 20% by 2040. (Measured as total KBTU / total building area) Enhancing building energy efficiency is crucial for reducing greenhouse gas emissions and increasing resilience to climate change. Energy-efficient structures use less power for heatfng, cooling, and electricity, cutting their carbon footprint. This decrease in energy use directly helps lower emissions, a major factor in climate change. Moreover, these buildings often feature improved insulatfon and weatherproofing, making them more capable of withstanding climate-related challenges like extreme heat, storms, and flooding. Increasing energy efficiency of Oshkosh municipal buildings to reduce their energy use intensity (total energy used divided by total building area) by 12% would reduce the existfng Oshkosh building energy use by 2,267,000 kWh and 70,200 therms annually. Actions E 1- 1 Introduce a City of Oshkosh Sustainable Building Policy establishing energy efficiency guidelines for City of Oshkosh buildings. Establish minimum standards for energy efficiency, "net zero" buildings, alternatfve energy generatfon, and high-efficiency appliances/equipment. E 1- 2 By 2029, complete a Facilitfes Energy Audit of all City buildings and sites, including conversion of outdoor lightfng to Dark Sky–approved LEDs. Use audit results to set prioritfes for capital budgets and maintenance schedules in compliance with City energy efficiency goals and the Sustainable Building Policy (see actfon E1-1). Implement improvements within five years of each audit. Encourage other public agencies within Oshkosh to adopt similar policies. E 1- 3 Implement the recommendatfons of the November 7th, Elevate Energy 2024 Energy and Water Efficiency Assessment for Fire Statfon #19. E 1- 4 Introduce a policy that requires all City of Oshkosh facilitfes to be annually benchmarked using ENERGY STAR Portiolio Manager. E 1- 5 Conduct an occupancy and plug load efficiency study of primary City facilitfes. Develop a “Plug Load and Occupancy Energy Efficiency Guide” with operatfonal practfces, including workspace energy reductfon. Provide on-going training to all existfng City employees and all new City hires. E 1- 6 Convert all City of Oshkosh owned parking lights, exterior building lights, and streetlights to LED by 2030. Maximize appropriate use of motfon-detectfon street or path lightfng. E 1- 7 Require all City-funded or City-financed public and private projects to meet City of Oshkosh Sustainable Building Policy (see actfon E1-1). Projects receiving pass-through grants may be exempted from this requirement. E 1- 8 Establish an annual internship positfon to support integratfng new building operatfon practfces for increased energy efficiency to meet the goals of this plan. City-reported energy use; City-reported total municipal building area Strategy Metrics: 5-3 | CITY OF OSHKOSH ENERGY PLAN Energy Roadmap Strategy E 2 Increase adoptfon of high-performance building constructfon technology, achieving 1% Net Zero buildings within City of Oshkosh building portiolio by 2030 and 5% by 2040. (measured on square foot basis) High-performance buildings are those which deliver a higher level of energy-efficiency performance— typically 30% better than buildings designed to meet code—while Net Zero buildings are high- performance buildings which also generate as much energy on-site as they consume. Exploring, integratfng, and expanding high-performance and Net Zero building strategies into City of Oshkosh municipal facility design, constructfon, and renovatfon projects can help identffy and implement successful approaches to advancing energy and operatfonal cost savings within county operatfons while reducing GHG emissions. For municipal buildings to meet this strategy they may be either a "Net Zero" building, or a building which is "Net Zero Ready" and that achieves an ENERGY STAR score of 75 or higher measured by share of total building area. Actions E 2- 1 Develop a Net Zero Ready Guide and Checklist for all City building projects. The guide will align with the City’s Sustainable Building Policy, outline net zero strategies and technologies, recommend recycled and low-carbon materials, and include standard RFP language. E 2- 2 Following the completfon of the City of Oshkosh Facilitfes Energy Audits of all facilitfes (see actfon E1-2), identffy potentfal sites for Net Zero retrofit/renovatfon and establish an implementatfon plan and tfmeline. E 2- 3 Implement a Net Zero pilot project on a selected preferred site by 2030. E 2- 4 Establish a Revolving Loan Program to fund net zero strategies in City facilitfes, including high- performance efficiency and renewable energy projects with appropriate returns. Use the fund to implement all cost-effectfve resource-efficiency measures. Reinvest operatfonal savings into the loan program, with a portfon returned to partfcipatfng departments to support further efficiency improvements. City-reported buildings meetfng high-performance criteria Strategy Metrics: CITY OF OSHKOSH ENERGY PLAN | 5-4 Energy Roadmap Strategy E 3 Implement “fuel switching" of City of Oshkosh facilitfes from on-site fossil fuel combustfon to non-fossil fuel sources, achieving 20% by 2035 and 40% by 2040. (includes transitfon to beneficial electrificatfon and renewable fuels) On-site natural gas combustfon represents 21% of all City of Oshkosh municipal building GHG emissions annually. As the city’s electric grid increases use of carbon-free electricity, building heatfng fuel will become an increasingly important target for emission reductfons. Initfatfng a fuel switching program for City facilitfes is an important priority to achieve significant reductfons of emissions from City operatfons. This process involves replacing traditfonal fossil fuel-based heatfng systems with electric ones or with systems that use net zero emission renewable fuels. Switching to electric heatfng technologies can also have substantfal air quality benefits. Actions E 3- 1 Conduct a Thermal Fuel Switching Assessment and Actfon Plan for all City facilitfes to eliminate on-site fossil fuel use. Collaborate with regional energy partners to implement building-specific actfons and establish a replacement schedule for systems such as hot water and space heatfng. Explore electricity storage solutfons and publish a case study to share lessons learned with the community. Target conversion of 20% of facilitfes by 2035 and 40% by 2040. E 3- 2 Require all new water heaters to be electric, solar thermal, or other non-fossil models, and establish a replacement schedule for existfng propane and natural gas units. E 3- 3 Establish a policy prohibitfng the purchase of fossil fuel–burning equipment, including water and space heatfng; replacements must use electric or other zero-emission, non-fossil sources. E 3- 4 Implement a pilot project to replace fossil fuel systems with solar thermal at one or more City facilitfes. E 3- 5 Identffy renewable natural gas purchase or self-generatfon optfons for remaining gas equipment and implement a transitfon. Target 10% renewable natural gas use by 2035 and 100% by 2040. City natural gas accounts; City-reported fuel switching projects; City-reported natural gas consumptfon Strategy Metrics: 5-5 | CITY OF OSHKOSH ENERGY PLAN Renewable Energy Certificates (RECs) in Emissions Accounting As noted in Sectfon 4, in support of the City of Oshkosh clean energy goals, it will be critical for the City to retain all REC’s associated with any renewable energy generation, purchase, or subscription entered into. (see “Renewable Energy Certfficates” for more) Energy Roadmap Strategy E 4 Achieve 50% renewable electricity for all City of Oshkosh operatfons by 2035 and 100% by 2040. (on-site and purchased) Municipalitfes can lead the way in adoptfng renewable energy. On-site installatfons provide an opportunity for the City to explore micro-grids, energy storage, and other strategies to boost the resilience of municipal facilitfes. For the City of Oshkosh municipal operatfons, buildings unsuitable for on-site renewable energy, purchasing renewable energy from utflity providers is a viable optfon to achieve zero-emission electricity goals. For propertfes suitable for solar, increasing on-site renewable use not only cuts GHG emissions but also offers cost savings and improves energy resilience. Actions E 4- 1 Install solar on all feasible City buildings and sites per the Solar Feasibility Assessment (see plan sectfon 4). Complete Priority 1 sites by 2035 and Priority 2 sites by 2040. Pursue partnerships with adjacent property owners to maximize solar capacity. The City shall retain rights to all green attributes and Renewable Energy Certfficates (RECs). Explore micro-grids, solar+storage, and other resilience strategies. E 4- 2 Purchase renewable electricity for all facilitfes without on-site generatfon to reach 50% renewable supply by 2035 and 100% by 2040, using utflity RECs or market optfons such as The Midwest Renewable Energy Tracking System (M-RETS) E 4- 3 Require all new constructfon and major renovatfons of City facilitfes to meet Solar Ready standards in the Net Zero Ready Guide (see actfon E2-1), include a solar feasibility and ROI assessment, and incorporate on-site solar where cost-effectfve. Encourage other public agencies in Oshkosh to adopt similar policies. E 4- 4 Install solar panels to power lightfng on new signs installed by the City where feasible. City-reported on-site energy productfon; City-reported electricity consumptfon Strategy Metrics: CITY OF OSHKOSH ENERGY PLAN | 5-6 Energy Roadmap Strategy E 5 Maintain appropriate funding to support plan implementatfon. Energy efficiency and renewable energy projects often cost money upfront but lead to long-term benefits. These projects typically require a period of years to provide a full return on investment. Meanwhile, current funding might not fully cover up-front project needs or may not fit project funding requirements. To close these gaps, communitfes are looking at new ways to account and pay for these types projects. Actions E 5- 1 Establish a policy directfng all operatfonal savings from energy efficiency, fuel efficiency, and renewable energy in City buildings into an Energy Plan Fund to finance Energy Plan initfatfves. E 5- 2 Maintain a database of federal, state, and philanthropic funding opportunitfes for climate actfon, and pursue grant applicatfons, including collaboratfons with other communitfes and entftfes. E 5- 3 Establish and maintain an annual budget, including dedicated staff funding and project support, to implement the Energy Plan.

System Metrics: an overview of the proposed array size, efficiency rating, and total annual electrical generation. Monthly Production: an estimate of electric generation by month, responding to varying weather and sun conditions. System Losses: all solar arrays have “losses” representing a reduction in total energy generated from the maximum potential of the panels. This provides an estimate of losses by category, such as shading or high panel temperature in strong sunlight conditions. Array Concept – the second page of the “Annual Production Report” provides an illustration of the solar array concept and a summary of the array components planned. Components: an overview of the solar array components used in modeling the potential production. Specific components such as the solar module or inverters used will have slight performance differences. Detailed Layout provides an illustration of the solar PV array design concept used in this feasibility assessment. Alternative array locations and configurations are possible and may affect the potential array’s ultimate cost and performance. Project Budget - For each site, the Project Budget includes a preliminary opinion of project costs. This estimate is based on national solar PV installation cost data provided by the National Renewable Energy Laboratory (NREL) which have then been modified for local construction cost indices. Costs shown represent 2020 dollars. Projects planned for future installation should anticipate an increase in labor costs, however, system component costs are likely to remain constant or decrease on a per-kilowatt basis. Administrative Costs: provide an allowance for general project costs such as legal/contract review and soil borings (for ground mounted arrays). Installation Costs: provides a detailed opinion of the actual solar array construction costs. This section is what a building owner might anticipate paying a solar contractor to construct the array. Professional Fees: provides an allowance for possible professional fees, such as design assistance or procurement assistance the site owner or design/build entity may engage. Contingency: provides an allowance for a recommended project contingency to cover unexpected costs. CITY OF OSHKOSH ENERGY PLAN | B-2 30-Year Energy Generation - All solar PV panels lose some degree of efficiency over time due to material degradation caused by unavoidable circumstances, including UV exposure and weather cycles. Panel degradation and system generation losses are typically covered under panel warranty, usually at 0.7% to 1% annual losses. Studies by NREL, however, show average panel degradation rates for contemporary panels to be less than 0.5% annually. The “life span” energy generation projections included here are predicted using a 0.8% annual degradation factor. “Degradation” refers to the decline in output that all solar panels experience over time. Due to system degradation over time, the percentage of facility annual energy need that is met by an array initially will not be the same level met by an array in later years. To assist site owners in anticipating this change over time, the schedule provided indicates the percentage of annual site energy use which can be met by the solar array(s) each year. Based on the modeled annual energy generation, the value of the solar energy generated is calculated for each site. Estimates include the value of energy consumed on site as well as the value of annual energy sold to the grid. Taken together, these values represent the potential life-span economic value of the solar array, which can then be compared against the estimated project costs. Energy Generation Sched: an estimate of annual array performance. Financing: an allowance for array loan or bonding finance. Annual Expenses: allow- ances for insurance and maintenance expenses. Simplified Cash Flow: an estimate of array cash flow / pay back annually for 30 year term.

Site Solar Feasibility Reports by Building— City Hall Site Suitability The roof configuration of the City Hall building is moderately well suited for solar PV installation, with reasonably good orientation, configuration, and moderate to low obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of as much as 20 years. The site is moderately to heavily covered with trees, however, placement of the trees result in no to minimal rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 9% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $440,424, representing a net benefit (after construction, maintenance, and financing costs) of $242,477. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Fire Station 15 Site Suitability The roof configuration of the Fire Station 15 building is well suited for solar PV installation, with good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is planned for replacement in 2026. If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 58% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $674,910, representing a net benefit (after construction, maintenance, and financing costs) of $421,336. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Recommended Site Priority: Priority 1 (0-2 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Fire Station 19 Site Suitability The roof configuration of the Fire Station 19 building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and low obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $565,641, representing a net benefit (after construction, maintenance, and financing costs) of $310,820. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Police Station Site Suitability The roof configuration of the Police Station building is moderately well suited for solar PV installation, with reasonably good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is in reasonable condition and has a remaining useful life of 6-10 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 18% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $1,239,365, representing a net benefit (after construction, maintenance, and financing costs) of $805,788. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Grand Theater Site Suitability The roof configuration of the Grand Theater building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and low obstructions due to rooftop equipment. City data indicates the roof is planned for replacement in 2028. If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation. The site is moderately to heavily covered with trees, however, placement of the trees result in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 20% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $327,263, representing a net benefit (after construction, maintenance, and financing costs) of $164,443. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Recommended Site Priority: Priority 1 (0-2 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Oshkosh Center Site Suitability The roof configuration of the Oshkosh Center building is well suited for solar PV installation, with good orientation, configuration, and low obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is moderately to heavily covered with trees, however, placement of the trees result in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 10% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $1,499,905, representing a net benefit (after construction, maintenance, and financing costs) of $1,000,572. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Electric / Bus Garage Site Suitability The roof configuration of the Electric / Bus Garage building is moderately well suited for solar PV installation, with reasonably good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is in reasonable condition and has a remaining useful life of 6-10 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 89% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $987,344, representing a net benefit (after construction, maintenance, and financing costs) of $642,538. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Public Works Field Ops Site Suitability The roof configuration of the Public Works Field Ops building is well suited for solar PV installation, with good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 15 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $4,838,965, representing a net benefit (after construction, maintenance, and financing costs) of $3,310,826. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Senior Center North Site Suitability The roof configuration of the Senior Center North building is moderately well suited for solar PV installation, with reasonably good orientation, configuration, and moderate to low obstructions due to rooftop equipment. City data indicates the roof is planned for replacement in 2025/26. If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation. The site is moderately covered with trees, however, placement of the trees result in no to minimal rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $509,237, representing a net benefit (after construction, maintenance, and financing costs) of $291,790. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Recommended Site Priority: Priority 1 Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Senior Center South Site Suitability The roof configuration of the Senior Center South building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and low obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $739,535, representing a net benefit (after construction, maintenance, and financing costs) of $472,731. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Parks & Forestry Site Suitability The roof configuration of the Parks & Forestry building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and low obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $1,000,267, representing a net benefit (after construction, maintenance, and financing costs) of $669,708. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Four Seasons Pavillion Site Suitability The roof configuration of the Four Seasons Pavillion building is well suited for solar PV installation, with good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 49% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $431,195, representing a net benefit (after construction, maintenance, and financing costs) of $226,141. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Pollock Community Water Park Site Suitability The roof configuration of the Pollock Community Water Park building is well suited for solar PV installation, with good orientation, configuration, and low to moderate obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 45% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $607,467, representing a net benefit (after construction, maintenance, and financing costs) of $362,530. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Wastewater Treatment Plant Site Suitability The roof configuration of the Wastewater Treatment Plant building is well suited for solar PV installation, with good orientation, configuration, and low to moderate obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 3% of the site’s reported annual electricity consumption. Ground Mounted Array: The concept explored includes two ground mounted arrays which boost total on-site generation, however, the combined rooftop and ground mounted arrays do not offset all of the electricity used on site. The ground mounted arrays’ first year generation to offset approximately 9.6% of the site’s reported annual electricity consumption, for a total first year on site generation of 12.6%. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $6,823,579, representing a net benefit (after construction, maintenance, and financing costs) of $4,736,883. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Water Filtration Site Suitability The roof configuration of the Water Filtration building is well suited for solar PV installation, with good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is planned for replacement by 2026. If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The array’s first year generation is estimated to offset approximately 20% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $5,429,300, representing a net benefit (after construction, maintenance, and financing costs) of $3,633,476. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Recommended Site Priority: Priority 1 (0-2 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Water Distribution Site Suitability The roof configuration of the Water Distribution building is well suited for solar PV installation, with good orientation, configuration, and moderate obstructions due to rooftop equipment. City data indicates the roof is planned for replacement by 2029. If planned roof replacement has not yet been completed, replacement is recommended in conjunction with, or prior to, solar array installation. The site is moderately to heavily covered with trees, however, placement of the trees result in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $721,126, representing a net benefit (after construction, maintenance, and financing costs) of $451,563. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Recommended Site Priority: Priority 1 (0-2 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Fire Station 18 Site Suitability The roof configuration of the Fire Station 18 building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and moderate solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site is moderately covered with trees with the placement of certain trees resulting in moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $425,469, representing a net benefit (after construction, maintenance, and financing costs) of $207,233. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Recommended Site Priority: Priority 2 (0-5 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Sawyer Street Storage Site Suitability The roof configuration of the Sawyer Street Storage building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and moderate solar obstructions due to rooftop equipment. City data indicates the roof is in reasonable condition and has a remaining useful life of 6-10 years. The site is moderately covered with trees with the placement of certain trees resulting in moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $198,269, representing a net benefit (after construction, maintenance, and financing costs) of $79,427. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Recommended Site Priority: Priority 2 (0-5 year) Click to return to Table of Contents Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Facilities Maintenance Storage Site Suitability The roof configuration of the Facilities Maintenance Storage building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and moderate solar obstructions due to rooftop equipment. City data indicates the roof is in reasonable condition and has a remaining useful life of 6-10 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $175,358, representing a net benefit (after construction, maintenance, and financing costs) of $72,691. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Recommended Site Priority: Priority 2 (0-5 year) Click to return to Table of Contents Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Transit Center Site Suitability The roof configuration of the Transit Center building is well suited for solar PV installation, with moderate orientation, good configuration, and no solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $280,151, representing a net benefit (after construction, maintenance, and financing costs) of $136,476. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Recommended Site Priority: Priority 2 (0-5 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Menomonie Zoo Maintenance Site Suitability The roof configuration of the Menomonie Zoo Maintenance building is moderately well suited for solar PV installation, with moderate orientation, good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is moderately to heavily covered with trees, however, placement of the trees result in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The rooftop array’s first year generation is estimated to offset approximately 25% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $80,850, representing a net benefit (after construction, maintenance, and financing costs) of $31,318. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Recommended Site Priority: Priority 2 (0-5 year) Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Riverside Cemetery Garage Site Suitability The roof configuration of the Riverside Cemetery Garage building is well suited for solar PV installation, with good orientation, good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in reasonable condition and has a remaining useful life of 6-10 years. The site is moderately covered with trees with the placement of certain trees resulting in moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $66,109, representing a net benefit (after construction, maintenance, and financing costs) of $21,712. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Click to return to Table of Contents Note: A structural assessment should confirm the building can support a rooftop array before project implementation. City roof data shows the roof is slated for imminent replacement; if not completed before installation, replacement should occur prior to or alongside the solar array. Values do not include the social cost of carbon emissions avoided due to operation of the solar array. Recommended Site Priority: Payback may improve with improved market costs.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Menomonie Reetz Comfort Concession Site Suitability The roof configuration of the Menomonie Reetz Comfort Concession building is moderately well suited for solar PV installation, with moderate orientation, moderately good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the electricity used on site in the first year. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $111,517, representing a net benefit (after construction, maintenance, and financing costs) of $34,884. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Menomonie Train Station Concession Site Suitability The roof configuration of the Menomonie Train Station Concession building is moderately suited for solar PV installation, with moderate orientation, moderately good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The rooftop array’s first year generation is estimated to offset approximately 53% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $40,641, representing a net benefit (after construction, maintenance, and financing costs) of $7,879. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Abe Rochlin Park Site Suitability The roof configuration of the Abe Rochlin Park building is moderately well suited for solar PV installation, with good orientation, moderate configuration, and no solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The rooftop array’s first year generation is estimated to offset approximately 70% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $40,641, representing a net benefit (after construction, maintenance, and financing costs) of $7,879. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Riverwalk Site Suitability The roof configuration of the Riverwalk building is moderately well suited for solar PV installation, with moderately good orientation, moderately good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is not capable of offsetting all of the electricity used on site. The rooftop array’s first year generation is estimated to offset approximately 95% of the site’s reported annual electricity consumption. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $47,626, representing a net benefit (after construction, maintenance, and financing costs) of $9,763. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Police Evidence Garage Site Suitability The roof configuration of the Police Evidence Garage building is moderately suited for solar PV installation, with moderately good orientation, moderately good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site does not have significant solar obstructions. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $46,227, representing a net benefit (after construction, maintenance, and financing costs) of $7,055. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Menomonie Kiwanis Park Shelter Site Suitability The roof configuration of the Menomonie Kiwanis Park Shelter building is moderately suited for solar PV installation, with good orientation, good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is moderately to heavily covered with trees resulting in moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $13,580, representing a net benefit (after construction, maintenance, and financing costs) of -$4,118. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Menomonie Park Maintenance Site Suitability The roof configuration of the Menomonie Park Maintenance building is moderately well suited for solar PV installation, with good orientation, good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is moderately to heavily covered with trees, however, placement of the trees result in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $31,238, representing a net benefit (after construction, maintenance, and financing costs) of -$6,895. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— South Park Site Suitability The roof configuration of the South Park building is moderately well suited for solar PV installation, with moderately good orientation, good configuration, and low solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is moderately to heavily covered with trees resulting in moderate to heavy rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $37,414, representing a net benefit (after construction, maintenance, and financing costs) of $2,941. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Si m p l i f i e d C a s h F l o w P r o j e c t i o n Site Solar Feasibility Reports by Building— Red Arrow Park Site Suitability The roof configuraƟon of the Red Arrow Park building is moderately suited for solar PV installaƟon, with moderately good orientaƟon, good configuraƟon, and moderate solar obstrucƟons due to rooŌop equipment. City data indicates the roof is in good condiƟon and has a remaining useful life of over 20 years. The site does not have significant solar obstrucƟons. RooŌop Array: The concept explored in this opƟon is a rooŌop solar array maximizing rooŌop solar capacity. The array is capable of offseƫng all of the reported annual electricity used on site. Ground Mounted Array: The site uƟlizaƟon does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at porƟons of the parking within the site, however, these arrays are not anƟcipated to be as cost effecƟve as the rooŌop array and have not been included in this assessment. PotenƟal Financial Performance The array should qualify for the Tax-Exempt Direct Pay opƟon of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s Ɵmeframe, currently through end of 2025. Project esƟmates provided in this report do not include anƟcipated parƟcipaƟon in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of -$5,457, represenƟng a net benefit (aŌer construcƟon, maintenance, and financing costs) of -$11,941. LifeƟme benefit of the solar array could out perform this projecƟon if uƟlity supplied electricity increases at more than the assumed 20-year naƟonal average annual escalaƟon rate (3.12%). The array’s cost savings could be increased by implemenƟng energy efficiency measures, demand reducƟon strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a compeƟƟve design-build request covering mulƟple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy PotenƟals Study Note: A structural assessment should confirm the building can support a rooŌop array before project implementaƟon. Values do not include the social cost of carbon emissions avoided due to operaƟon of the solar array.

Site Solar Feasibility Reports by Building— Fugleberg Boat Launch Site Suitability The roof configuration of the Fugleberg Boat Launch building is moderately suited for solar PV installation, with moderately good orientation, good configuration, and moderate solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of up to 20 years. The site is minimally to moderately covered with trees resulting in minimal to moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $12,890, representing a net benefit (after construction, maintenance, and financing costs) of -$4,273. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

Site Solar Feasibility Reports by Building— Stevens Park Site Suitability The roof configuration of the Stevens Park building is moderately suited for solar PV installation, with moderate orientation, good configuration, and moderate solar obstructions due to rooftop equipment. City data indicates the roof is in good condition and has a remaining useful life of over 20 years. The site is minimally to moderately covered with trees resulting in moderate rooftop solar obstruction during high production timeframes. Rooftop Array: The concept explored in this option is a rooftop solar array maximizing rooftop solar capacity. The array is capable of offsetting all of the reported annual electricity used on site. Ground Mounted Array: The site utilization does not readily support ground mounted arrays. Carport / Structured Array: Carport arrays are feasible at portions of the parking within the site, however, these arrays are not anticipated to be as cost effective as the rooftop array and have not been included in this assessment. Potential Financial Performance The array should qualify for the Tax-Exempt Direct Pay option of the Federal Solar Investment Tax Credit (“Tax Benefit”) if installed within the program’s timeframe, currently through end of 2025. Project estimates provided in this report do not include anticipated participation in the Federal tax credit. Over a 30 year lifespan, the array is projected to generate a gross value of $1,280, representing a net benefit (after construction, maintenance, and financing costs) of -$8,788. Lifetime benefit of the solar array could out perform this projection if utility supplied electricity increases at more than the assumed 20-year national average annual escalation rate (3.12%). The array’s cost savings could be increased by implementing energy efficiency measures, demand reduction strategies, and adding energy storage. Grants or low/no-interest loans could further improve financial payback, while a competitive design-build request covering multiple sites under one contract could help reduce project costs. City of Oshkosh Facility Renewable Energy Potentials Study Note: A structural assessment should confirm the building can support a rooftop array before project implementation. Values do not include the social cost of carbon emissions avoided due to operation of the solar array.

B-1 | CITY OF OSHKOSH ENERGY PLAN Click here to return to TOC Potential Cumulative Costs and Savings From Plan Implementation Appendix C The following documents the calculations and source references used for estimating the potential cumulative costs and cost savings of the strategies included in the Energy Plan. Savings - grid electricity to solar Formula: Cumulative kWh converted to solar x Average cost savings per kWh = solar savings 1 kWh converted (goal year) 4,722,277 1 Cumulative kWh converted (through goal year) 28,333,661 2 Average solar cost savings per kWh $0.110 3 Average solar installation cost per KW $2,392.00 4 Average kWh produced annually per solar pv KW installed 1,171 Estimated installed solar PV KW installed (goal year) 4,033 Estimated total solar installation costs $9,646,188 5 Estimated average lifespan kWh produced per solar pv KW installed 34,965 5 Estimated cumulative lifespan kWh produced 141,004,232 6 Estimated value of cumulative lifespan kWh produced $25,163,917 Average solar cost savings per kWh produced $0.110 Solar Savings $3,118,162 Estimated Average Annual Savings $311,816 1 Assumes 50% of goal achieved through onsite solar and 50% of goal achieved through grid purchase. 2 Recent average cost per KW is 1000x the per watt cost reported for commercial solar arrays by NREL ( https:// www.nrel.gov/docs/fy21osti/77324.pdf https://www.nrel.gov/solar/market-research-analysis/solar-installed-system- cost.html ) Value includes assumed financing costs based on 20% initial payment and 80% financed through 10 year loan with 3.5% annual interest rate. Potential savings from tax credits, depreciation, or grants are not included and would reduce these costs. 3 Based on Solar Feasibility Assessments using Wisconsin Public Service recommended blended kWh savings rate. See Ap- pendix 4 Calculations are based on the geographic energy production factor ( https://www.nrel.gov/docs/fy04osti/35297.pdf ) mul- tiplied by an average performance ratio of 78% ( https://www.nrel.gov/docs/fy13osti/57991.pdf ) 5 Based on an assumed average useful life of 32.5 years according to NREL research with an average degradation rate of 0.5% ( https://www.nrel.gov/docs/fy24osti/90042.pdf ) 6 Savings per kWh based on average electricity cost per kWh ( https://www.electricitylocal.com/ ) calculated to the solar array's midlife (year 16) using an estimated average electrical cost inflation of 2% annually Utility Purchased Renewable Formula: Cumulative kWh converted to utility purchased renewable x Average cost/savings per kWh = Utili- ty Purchased Cost/Savings 1 kWh converted (goal year) 4,722,277 Cumulative kWh converted (through goal year) 28,333,661 7 Average utility purchased cost/savings per kWh -$0.013 Utility Purchased Cost/Savings -$361,821 Estimated Average Annual Savings -$36,182 CITY OF OSHKOSH ENERGY PLAN | B-2 1 Assumes 50% of goal achieved through onsite solar and 50% of goal achieved through grid purchase. 7 The average cost/savings per kWh of utility purchased renewable energy subscription is based on Wisconsin Public Service "Naturewise" renewable energy program block rate costs. Costs may be lower with direct purchase of RECs from market places such as MRETS Electrical Energy Efficiency Formula: Cumulative kWh saved from energy efficiency x Average cost per kWh = Gross Non-Residential electrical energy efficiency savings - Non-Residential Efficiency Upgrade Costs = Electrical Energy Efficiency Savings kWh saved (goal year) 2,266,693 Cumulative kWh saved (through goal year) 13,600,157 8 Average cost per kWh $0.130 Gross Electrical Energy Efficiency Savings $1,768,020 9 Electrical Efficiency Upgrade Costs -$1,414,416 Net Electrical Energy Efficiency Savings $353,604 Estimated Average Annual Savings $35,360 8 Energy efficiency savings per kWh saved based on Wisconsin Public Service recommended blended kWh savings rate. 9 Assumed energy efficiency upgrade costs are calculated assuming an average ROI of 20% ( https://www.aceee.org/sites/ default/files/publications/researchreports/E112.pdf ). Negative numbers indicate increased consumer spending. Natural Gas Energy Efficiency Formula: Cumulative therms saved from energy efficiency x Average cost per therm = Gross Non-Residential natu- ral gas energy efficiency savings - Non-Residential Natural Gas Efficiency Upgrade Costs = Net Electrical Natural Gas Efficiency Savings 10 Therms saved (year 10) 171,938 10 Cumulative therms saved 1,031,626 11 Average cost per therm $0.593 Gross Natural Gas Energy Efficiency Savings $611,754 9,10 Natural Gas Efficiency Upgrade Costs -$489,403 Net Natural Gas Energy Efficiency Savings $122,351 Estimated Average Annual Savings $12,235 9 Assumed energy efficiency upgrade costs are calculated assuming an average ROI of 20% ( https://www.aceee.org/sites/ default/files/publications/researchreports/E112.pdf ). Negative numbers indicate increased consumer spending. 10 Includes fuel switching from fossil fuel heat to electric 11 Energy efficiency savings for natural gas is based on average natural gas cost per therm https://naturalgaslocal.com/ Potential Total Cumulative Energy Cost Savings Formula: Solar savings + Utility purchased renewable + Electrical efficiency savings + Natural gas energy efficien- cy savings - Increased electrical costs = Potential Total Cumulative Energy Savings Solar savings $3,118,162 Utility purchased renewable cost/savings -$361,821 Electrical efficiency savings $353,604 Natural gas energy efficiency savings $122,351 Potential Total Cumulative Energy Savings $3,232,296 Potential Total Annual Energy Savings $323,230
