Ameresco and City of Somersworth start New Hampshire’s first landfill solar project on Superfund site

Ameresco, Inc., a leading cleantech integrator known for its expertise in energy efficiency and renewable energy, and the City of Somersworth, have officially broken ground on New Hampshire’s first solar photovoltaic (PV) installation to be placed on a Superfund site. The project, which is set to transform the Somersworth Landfill into a hub for renewable energy, was inaugurated with significant attendance from officials, including the U.S. Environmental Protection Agency (EPA).

Groundbreaking Solar PV Project to Boost Sustainability

The new solar PV installation, boasting a capacity of 2,577 kW-DC / 1,992 kW-AC, is designed to generate over 67 million kWh of electricity over the next 20 years. Initially, the system is expected to produce approximately 3,523,443 kWh in its first year. This amount of energy production will help the city avoid approximately 2,461 metric tons of CO2 annually—equivalent to the annual electricity consumption of 486 homes or the removal of 586 gas-powered cars from the road. The environmental impact of the project is akin to the carbon sequestration of 2,874 acres of U.S. forests in one year.

City Officials and Experts React to the Groundbreaking

Mayor Matt Gerding of the City of Somersworth highlighted the significance of the project in enhancing the city’s sustainability efforts. He noted, “This solar project represents a crucial step toward increasing our community’s sustainability and aligns with broader regional and state efforts. It’s vital that we integrate green energy into our energy portfolio, and I am thrilled to see this project come to fruition. My gratitude goes to the City Council, City staff, Ameresco, and our regulatory partners at the EPA and the New Hampshire Department of Environmental Services (NH DES) for their relentless efforts and collaboration.”

Mayor Gerding further emphasised, “This initiative is another example of Somersworth’s commitment to joining other communities in advancing towards a greener and cleaner future.”

Economic and Environmental Benefits

The energy generated by this solar project will be sold to the City of Somersworth through the state’s group net metering programme. In addition, the project will provide the city with lease payments and a Payment in Lieu of Taxes (PILOT). With all necessary permits and approvals from the EPA and NH DES already secured, construction is slated to commence between mid and late August.

Jon Mancini, Senior Vice President of Ameresco, expressed his enthusiasm about the project, stating, “We are excited to partner with the City of Somersworth on this groundbreaking landfill solar initiative. This project highlights the potential of repurposing land for renewable energy and enhancing the sustainability of landfills. We look forward to beginning construction and supporting the city’s transition to a clean energy future.”

The groundbreaking ceremony was attended by Congressman Chris Pappas, Mayor Matt Gerding, and representatives from the EPA, NH DES, City of Somersworth officials, and Ameresco executives, all of whom gathered to celebrate this pivotal moment in advancing the city’s sustainability goals.
