About this vehicle
The Department of the Army Installation Management Command Southwest Region established this Master IDIQ for energy savings performance contracting on May 8, 2015, with a shared ceiling of $1.5 billion; ordering closed on May 6, 2025, and the vehicle is no longer accepting new task orders. The successor vehicle, Energy Savings Performance Contracts IV, was awarded on June 9, 2025.
The Master IDIQ procures design, construction, operation, and maintenance of energy conservation measures at Army installations, including equipment and system installation, testing, operations, and repair. Work is performed at domestic and overseas Army facilities, with a concentration at Corps of Engineers installations.
Twenty-eight task orders have been awarded across the vehicle's lifecycle, with ordering activity concentrated in recent years: four orders in 2024 and three in 2023, down from one in 2025. The combined task-order potential value reaches $1.89 billion, of which $487.6 million (26 percent) has been obligated. Task orders span 20 to 30 years of performance, with ceiling values ranging from roughly $1.3 million to $421.4 million; the largest single award, issued September 30, 2025, to an awardee for a Naval Research Laboratory feasibility study, carries a $267.4 million ceiling.
Competition is concentrated among five primes. Siemens Government Technologies Inc. (4 orders, $381.7 million combined potential value), Energy Systems Group LLC (2 orders, $505.4 million), and Noresco LLC (5 orders, $171.8 million) dominate by value, together with Ameresco Inc. and Southland Industries, capturing 77 percent of combined potential value across 12 distinct primes. Customer demand originates almost entirely from the Department of the Army Corps of Engineers Engineering Support Center Huntsville, which issued 20 orders valued at $1.55 billion in combined potential value.
All 28 awarded task orders carry no set-aside designation, indicating unrestricted competition. Task orders are firm fixed price and typically incorporate third-party financing through notices of assignment.
