Ameresco, Inc. completed a $30 million Energy Savings Performance Contract (ESPC) that modernizes 3,600 U.S. Army family housing units at Fort Polk, Louisiana. The project is the first U.S. Army installation to install geothermal ground‑source heat pumps in every residential unit, replacing conventional HVAC systems and adding advanced metering, LED lighting, and hot‑water optimization.

The retrofit is projected to cut annual electrical consumption by 30% and generate more than $2.6 million in annual utility and operating‑cost savings for the Department of Defense. The savings demonstrate the effectiveness of the geothermal system and the broader impact of Ameresco’s low‑carbon solutions for federal customers.

While the announcement does not specify revenue recognition timing, the ESPC includes long‑term service and maintenance components that will generate recurring revenue over the contract term. The $30 million contract therefore adds a sizable, recurring revenue stream to Ameresco’s portfolio, reinforcing its strategy of combining project development with long‑term asset ownership and operations.

The Fort Polk project fits into Ameresco’s broader growth trajectory. The company reported record revenue of $581 million in Q4 2025 and guided 2026 revenue to $2.1 billion with adjusted EBITDA of $283 million. The Fort Polk contract is part of the portfolio of federal projects that underpin these results and support the company’s shift toward recurring revenue streams.

Velarium Energy partnered on the project, providing engineering and project‑management support, while Ameresco led the design, installation, and ongoing operations. The collaboration underscores Ameresco’s ability to leverage partners to deliver complex energy‑efficiency solutions at scale.

The completion of the Fort Polk ESPC reinforces Ameresco’s track record of delivering large federal contracts and positions the company to pursue additional defense and federal projects, supporting its long‑term growth strategy.
