About the company

Written by GovTribe AI ·

Ameresco Inc., a Massachusetts-based energy efficiency and renewable energy solutions provider, operates as a prime contractor on a $100.66 billion portfolio spanning energy savings performance contracts (ESPCs), facilities engineering, sustainable infrastructure, and power generation across federal agencies — predominantly competing in full-and-open procurements without set-aside restrictions.

Ameresco's federal footprint concentrates on Department of Energy ESPC vehicles and Army Corps of Engineers ESPC infrastructure. From the top-customer rankings, the Department of Energy anchors 16 awards valued at $60 billion combined potential value, while the Army Corps of Engineers Engineering Support Center Huntsville holds 20 awards worth $28.88 billion — together these two customers represent 92% of combined potential value across the 232 total awards in the source. The Department of the Navy Naval Facilities Engineering Command ranks third by award count (54 awards, $2.85 billion) but carries lower dollar magnitude per award, indicating a mix of smaller task orders within larger ESPC vehicles. The Department of Veterans Affairs Technology Acquisition Center Austin and the General Services Administration Public Buildings Service round out the top five by potential value. The activity trajectory shows recent awards declining from ten awards in 2023 to six in 2024 and nine in 2025, with only one award recorded in 2026 to date; however, the combined ceiling values mask significant latent work — obligated dollars across all awards total $1.8 billion against the $100.66 billion potential ceiling, indicating most work remains to be funded or executed.

Ameresco holds three major parent vehicles anchoring the federal business. The Department of Energy's $5 billion Energy Savings Performance Contracts Generation 4 IDIQ (ultimate completion August 2028) carries Ameresco's broadest civilian agency access for energy audits, project development, engineering, construction, and operations and maintenance. The Department of Energy's $2.67 billion Energy Savings Performance Contracts 2008-2019 vehicle supports legacy task orders with 34 deliveries. The Department of the Army Corps of Engineers' $3 billion Energy Savings Performance Contracts IV IDIQ (ultimate completion December 2035) enables Ameresco to deliver facilities upgrades and renewable energy at military installations. Recent representative work includes a $285.08 billion delivery order from the Department of the Navy for detailed feasibility studies at Naval Research Laboratory (awarded September 2025, ultimate completion January 2050); a $229.11 million General Services Administration Public Buildings Service order for energy conservation measures across 25 federal buildings in Indiana, Illinois, Minnesota, and Wisconsin (awarded January 2025, completion December 2043); and a $191.2 million Air Mobility Command delivery order for energy savings performance contracting at Joint Base McGuire-Dix Lakehurst (awarded October 2021, completion March 2046). Outside ESPC work, Ameresco was awarded a $19.49 million design-build construction contract by the Army Corps of Engineers for a six-megawatt natural gas microgrid at Fort Campbell, Kentucky (awarded September 2022, completion November 2025), and received two smaller ESTCP awards from Humphreys Engineer Center Support Activity totaling $2.46 million for V2X technology and additive manufacturing insulation retrofit pilot work. Ameresco also holds a prime recipient role on a Department of Energy Bipartisan Infrastructure Law grant for the Pu'uloa Microgrid and Backbone Project at Joint Base Pearl Harbor Hickam (awarded January 2025, completion December 2028).

Ameresco's NAICS footprint clusters on Facilities Support Services (76 awards) and Engineering Services (71 awards), with secondary categories including Commercial and Institutional Building Construction (19 awards), Other Electric Power Generation (7 awards), and Computer Systems Design Services (7 awards). Top PSC codes track the same trend: Housekeeping-Facilities Operations Support (35 awards), Special Studies/Analysis-Building Technology (16 awards), and Utilities-Electric (12 awards) dominate the award mix.

Service Contract Inventory data shows Ameresco invoiced $40.1 million across SCI-reportable federal service contracts in FY2022–FY2025, with FY2025 delivering $22.7 million on a reported footprint of 50.8 FTEs — a significant jump from FY2024's $6.8 million on 29.6 FTEs, suggesting a ramp in execution or contract labor intake. Across SCI prime records, Ameresco self-performs all labor with zero reported subcontractor engagement; hourly rate posture spans from $15.41/hr at the tenth percentile to a median of $82.46/hr, reaching $293.25/hr at the ninetieth percentile, reflecting a mix of labor categories from facilities operations staff to senior engineers. The corporate structure includes seven named subsidiaries: Ameresco Federal Solutions Inc., Ameresco Solutions Inc., Ameresco Select Inc., Optimum Operations LLC (self-certified small disadvantaged business), and three solar generation entities (Woodbridge Avenue Solar LLC, Montevue Lane Solar LLC, and Amrc BCE Holdings LLC), signaling vertical integration in renewable energy and facilities solutions. The recompete cliff shows minimal near-term exposure — only two awards (combined potential value $24.1 million) face completion within the next twenty-four months, indicating a stable, long-duration contract base extending to 2047 across most major vehicles.
