About this vehicle
The U.S. Army Engineering and Support Center, Huntsville awarded this Master IDIQ on May 3, 2013 to procure renewable and alternative energy through Power Purchase Agreements, with ordering closed as of September 22, 2023. This vehicle is no longer open for new task-order placement.
The vehicle contracts the purchase of energy production (not generation assets) from solar, wind, geothermal, and biomass facilities. The Government intends to pay only for energy delivered under PPAs with multi-decade terms. Task orders show actual performance concentrated in solar projects at Army installations, including Fort Campbell, Kentucky (ceiling $16 million, obligated $5.2 million through Year 18), Redstone Arsenal (ceiling $83 million, obligated $14.6 million through Year 26), and Fort Carson, Colorado (ceiling $38.6 million, obligated $246 thousand as of the most recent modification in November 2023).
Ordering momentum peaked sharply in the vehicle's first two years: 58 orders awarded in 2013, 33 in 2014, then dropped to three in 2015, two in 2016, and a single order in 2023. The 97 total task orders have obligated $20 million of a $137.6 million combined potential value (15% utilization). The portfolio is fragmented across 73 distinct prime contractors. Solar Star Mountain Post, LLC dominates by potential value, holding a single order worth $38.6 million (28% of the vehicle's combined potential value). New Generation Power Inc. leads by order count with four awards but minimal combined potential value. All task orders carry no set-aside designation and are unrestricted competitive awards.
Customer activity concentrates within the Army: the Engineering Support Center Huntsville placed 95 of 97 task orders ($16 million potential value), while a second Army entity issued two orders accounting for $121.6 million potential value. Many 2013–2014 orders were minimum-guarantee awards of five hundred dollars that were subsequently de-obligated due to contractor SAM registration expiration, contractor request, or failure to invoice by deadline. Order durations extend decades into the 2040s and 2050s, reflecting the long-term nature of energy purchase commitments. Place of performance is limited to Army installations in the continental United States.
