Ameresco has finished another government-related energy endeavor, this time completing a $30-million geothermal project powering nearly 3,600 homes at a U.S. Army base in Louisiana.
The Framingham-based firm replaced traditional HVAC systems with American-manufactured, ground-source heat pumps in homes at Fort Polk in Vernon Parish. The new geothermal-based system will improve energy security and lower costs, according to an Ameresco press release issued Wednesday.
“This milestone reinforces our commitment to delivering resilient, energy-efficient housing solutions for our military families,” Nicole Bulgarino, president of federal solutions and power infrastructure at Ameresco, said in the release. “Fort Polk is now the first Army installation to complete a full geothermal transition across all homes, strengthening resiliency and long-term sustainability.”
Ameresco worked with Velarium Energy, a strategic energy delivery partner to the U.S. Department of Defense, to complete the project. The geothermal installations come after prior project phases which saw the installation of energy-saving technologies, including LED lighting and upgrades to hot water systems.
Ameresco has frequently worked on U.S. government projects, including a $33-million project upgrading two National Archives and Records Administration sites, construction of a 1.1-megawatt solar facility at Fort Bragg in North Carolina, and construction of a backup power generation plant and underground transmission lines at a major military site in California.
Boosted by its work upgrading U.S. military sites, Ameresco generated $2 billion in revenue and $44 million in profit in 2025.
