City of Alton, IL and Ameresco Move Forward on 5MW Solar Project

The solar installation will be developed on a local closed municipal landfill and deliver approximately $1 million in revenue 

FRAMINGHAM, M.A. AND ALTON, I.L. – FEBRUARY 9, 2023 – Ameresco, Inc., (NYSE: AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced its partnership with the City of Alton, Illinois to develop and install a 5 megawatt AC (MWAC)/7 megawatt DC (MWDC) solar array. The solar installation will be developed on a local closed municipal landfill site in the city.

Over the life of the project, this solar installation is designed to deliver approximately $1 million in revenue to the City of Alton and surrounding local businesses. The renewable energy generated from the site will also help offset greenhouse gas emissions from conventional utility generation. In just the first year alone, the project is expected to generate approximately 10,000 MWh of electricity, reducing the city’s carbon footprint by over 7,000 tons. Over the 30-year lifespan of the solar array, this equates to about 278,000 MWh of energy generation and 197,000 metric tons of carbon emission reduction.

“Greenhouse gas emissions contribute to global warming, directly impacting communities through adverse weather events – including the increased flooding we’ve experienced here in Alton. Though global warming is a worldwide problem, this project will benefit our city through local job creation and increased property tax revenue while also reducing greenhouse gas emissions,” said Alton Mayor David Goins. “Facilitating this solar installation represents a significant step forward for the City as we continue our progress toward sustainable solutions in coordination with the Alton Cool Cities Committee.”

Ameresco and the City of Alton also plan to install a self-guided, instructional display near the array to inform visitors about the project and provide them with an opportunity to learn more about the associated benefits of clean energy. The completion of this project will enable Alton to make forward progress toward the clean energy transition goals laid out in the Illinois Climate and Equitable Jobs Act (CEJA). CEJA sets a target to get Illinois to 40% renewable energy by 2030 and 50% renewable energy by 2040.

“Once completed, this solar array is expected to provide the City of Alton with substantial revenue from clean energy generation while also making beneficial use of a previously un-usable brownfield site,” said Jon Mancini, Senior Vice President of Solar Project Development at Ameresco. “We’re honored to have been selected as partners on this project, and look forward to installing a state-of-the-art solar array designed to provide a great benefit to the local community through meaningful progress toward meeting the city’s clean energy goals.”

Construction is slated to begin in the spring of 2023 and is expected to reach completion by the end of the year.
