DOE Energy Savings Performance Contracts 2017-2022 (ESPC)

The Department of Energy Office of Energy Efficiency and Renewable Energy awarded this Master IDIQ for energy savings performance contracts on April 27, 2017, with a shared ceiling of $55 billion and a last date to order of April 27, 2022—ordering closed four years ago. The vehicle is no longer accepting new task orders; however, existing orders continue performing under firm fixed-price contracts with performance periods extending through 2049. Task orders under this vehicle finance energy audits, energy conservation measures, renewable energy projects, and measurement and verification services at federal facilities nationwide, with financing arranged by contractor partners.

The vehicle shows ongoing activity despite ordering closure, with one task order awarded as recently as May 12, 2026 (NASA Jet Propulsion Laboratory, $97.9 million ceiling). The portfolio contains 23 task orders with combined potential value of $2.15 billion, of which $825.4 million (38 percent) has been obligated. Award momentum declined over the last five years—averaging 3.2 orders per year from 2022–2026, down from 4 in 2022 and 5 in 2024. The predecessor vehicle (DOE Energy Savings Performance Contracts 2008–2019) indicates a pattern of five-year IDIQ awards from DOE in this space.

Ameresco Inc. dominates the vehicle, holding 9 of 23 orders with combined potential value of $968.5 million (45 percent of portfolio value). The next largest primes—CEG Solutions LLC ($384.9 million across 3 orders), Johnson Controls Government Systems LLC ($253.3 million across 3 orders), Constellation Energy Solutions LLC ($178.2 million across 2 orders), and Noresco LLC ($153.2 million across 2 orders)—collectively account for most remaining value, with a long tail of three smaller firms. All 23 task orders carry no set-aside designation, making the vehicle fully unrestricted and highly competitive at the prime level.

General Services Administration Public Buildings Service entities fund the majority of orders (roughly 57 percent by count), with the National Capital Region branch alone representing four orders totaling $778.3 million. Department of Defense, Department of Veteran Affairs, and other federal agencies round out a customer base spanning 15 distinct agencies. Task-order values range from zero-dollar audit awards through mega-orders exceeding $350 million (DEEE0008029-47PF0025F0227 for Region 5 deep energy retrofit at $229.1 million ceiling). Performance periods typically span 15–25 years, reflecting the long-term nature of financed energy improvements.

The Energy Service Companies (ESCO) under this Master IDIQ will conduct comprehensive energy audits for the Federal facility and identify improvements to save energy and/or implement renewable energy projects. In consultation with the Federal agencies, the ESCOs will design and construct projects that meets the agency's needs as well as arrange necessary financing.
