Ordering is modest: one, three, three, four, and one orders in 2021 through 2025, with the most recent award on September 30, 2025. Task orders cite the parent as ESPC III.

Awarded orders buy energy conservation measures on Army installations, including lighting, boiler, and rooftop HVAC upgrades, detailed feasibility studies, and debt service, performance-period, and measurement and verification payments under existing orders.
