AERECO Energy Solutions G G �m` For Every Need Utility Interconnection Application & Permitting I Extensive Experience We have extensive experience with navigating interconnection. The process is typically a critical path item in most distributed generation projects. Upon Notice to Proceed, Ameresco will begin the design drawings to submit an interconnection application to Indiana Michigan Power. The proposed project is based on connecting into the meter serving Wells 1&2 and the office building to avoid utility upgrades. We recommend investigating aggregating the meters to allow for a larger solar array to be installed or to reduce exported energy, both of which would improve the payback of the project. Procurement I High Quality Materials A high -quality material and well thought out design is crucial to the success of a solar photovoltaic array, which can effectively produce electricity for upwards of 30 years. Prioritization of proven quality materials and significant warranty are key components for material selection. Ameresco regularly installs PV modules from Tier I manufacturers for both customer and Ameresco owned projects. Ameresco recommends products from Tier I suppliers to ensure manufacturer longevity so that the warranty can be upheld for the term's duration. Due to the volume of projects we install, we are able to solicit pricing directly from manufacturers at a national level to obtain competitive pricing for high quality products. Ameresco is vendor neutral; however, with our experience, we recommend the following products or equal for this project. We have used all these manufacturers on past projects. In choosing products, we included domestically produced racking and inverters and chose an inverter that produced power at 480V to eliminate the need for a transformer, reducing first costs and lifetime maintenance costs. We will continue to work with Crossroads to find a product that meets the City's needs while providing workforce benefits. We can also discuss with the City the benefits of fixed tilt versus single axis tracker racking and can discuss the use of Valmont single axis tracker racking, a product with local Indiana manufacturing. • Inverters: Solectria XGI 1500 200/200-480 • Racking: APA Titan Duo 4-Rail Fixed Tilt Racking • Data Acquisition System (DAS): Ameresco/AssetPlannerTM Performance Warranties I Proposed Warranties Please refer to the following table for equipment performance warranties for the proposed project components. We have included standard warranties but are happy to discuss extended warranties, if desired. Proposed Component Warranties Pricing I Firm Fixed Price Solar projects have significant variation in cost per watt based on location, labor requirements, interconnection distance/voltage, site topography, production capabilities of the system, and project size. Ameresco proposes to install this 514kW-DC/400kW-AC system for a firm fixed price of $1,984,000 which is equal to $3.86/watt-DC. Ameresco has prepared a cashflow analysis for this system in Appendix A. Performance Contracting Firm I National & Local Ameresco, Inc. has been in the performance contracting business under its current name since 2000. From the inception of its predecessor firms, Ameresco and its predecessors has been offering energy related services in the energy industry for over 42 years. Ameresco's revenue for 2023 was $1.37 billion, and approximately seventy percent (70%) of our business is conducted on a performance contracting basis. Our local presence in Indiana covers the entire state, and most of the $150 Million in projects, have been completed under an energy savings performance contract.
