Storage Facility Rooftop Solar Installation

The City of Urbana in Champaign County, Illinois, is seeking proposals for a comprehensive rooftop solar photovoltaic installation project at its newly constructed Storage Facility located at 610 South Glover Avenue. This turnkey procurement requires a vendor to design, permit, install, and commission a solar system on the facility's south-facing, standing seam metal roof. The project's key objectives include installing a solar system that meets the facility's electrical demand without generating surplus net metering credits, with a system size not exceeding 100% of the building's current electricity consumption. Vendors must submit detailed proposals that include company background, solar system specifications, module layout, interconnection process, and potential incentive program details. The RFP mandates documentation on system size, production, module and inverter specifications, and future expansion potential. Proposal submissions are due by March 16, 2024, at 12:00 am, with a question submission deadline of March 4, 2024. Vendors must comply with the Illinois Prevailing Wage Act, which requires labor to be paid at prevailing wage rates.

The procurement does not explicitly specify set-aside designations or restrictions for disadvantaged enterprises. Vendors are required to propose either a cash purchase or a power purchase agreement option and must assist the City in leveraging incentive programs such as net metering, Solar For All, and Illinois Shines. While no incumbent vendors are mentioned, the project involves integrating with the existing Ameren Illinois electrical infrastructure, with the facility currently having an electrical meter, a Davis Electric panel with a 400-amp main breaker, and an electrical system operating at 120/240v. The facility's monthly electric demand ranges from 356 to 1,102 kilowatt-hours, providing a baseline for system sizing. Although a specific budget range is not disclosed, the most recent Ameren utility bill indicates monthly electrical costs around $222.81, suggesting potential long-term cost savings through the solar installation. The project emphasizes comprehensive documentation, including design documents, installation manuals, and post-installation monitoring hardware and software.
