About Eversource Energy Service Company
Eversource Energy Service Company, doing business as Eversource Energy Service Co., a Hartford, Connecticut-based for-profit utility provider, supplies electric, natural gas, and energy infrastructure services to federal agencies across the Northeast as a prime contractor (99% of awards), competing on a full-and-open basis with no set-aside designations. The company serves over 3.6 million customers regionally and operates across franchised service territories in Massachusetts, Connecticut, and New Hampshire.
Eversource's federal capability portfolio centers on utility distribution and energy management at federal facilities. Representative recent work includes a $3.16 million ten-year delivery order from the National Archives and Records Administration for electricity distribution at the John F. Kennedy Library in Dorchester, Massachusetts (awarded July 2021, running through July 2031); a $2.67 million definitive contract from the Air Force Materiel Command for electric vehicle charging station make-ready infrastructure installation at Hanscom Air Force Base, Massachusetts (awarded September 2023); a $970 thousand delivery order from the Department of Transportation for electric transmission services at the Volpe National Transportation Systems Center in Cambridge, Massachusetts (awarded July 2021, completed January 2024); and recurring annual delivery orders from the Federal Correctional Institution Berlin and Federal Correctional Institution Danbury supplying electric and natural gas utility services, with individual orders ranging from roughly $28 thousand to $758 thousand. Work extends across electric power distribution (108 awards), natural gas utilities (21 awards), and electrical infrastructure installation (2 awards).
Customer concentration is heavily weighted toward correctional and cemetery facilities, with the Veterans Integrated Service Network 1 (a Department of Veterans Affairs component) accounting for 27 awards and $5.7 million in combined potential value, Federal Correctional Institution Berlin for 18 awards and $3.3 million, and Federal Correctional Institution Danbury for 11 awards and $7.3 million. However, two larger-dollar customers dominate the potential-value picture: the General Services Administration Public Buildings Service Central Office Energy Division holds 2 awards worth $100 million combined potential value, and the Department of Homeland Security US Coast Guard holds 2 awards worth $86.2 million combined potential value. Together, these five customers account for 95% of all combined potential value and 70% of award count.
Eversource sits on two indefinite-delivery contract vehicles. The primary vehicle is Indefinite Delivery Contract GS00P16BSD1211 under the General Services Administration, which anchors 90 task orders carrying $108.5 million in combined potential value. A second indefinite-delivery vehicle, FA870225DB002, appears with minimal activity. Most significantly, Eversource was awarded a single-award indefinite-delivery contract from the Energy Division on May 1, 2026 (the most recent award), with a $50 million ceiling running through April 30, 2036, covering electric, natural gas, and energy management services across Massachusetts, Connecticut, and New Hampshire franchised service areas under Executive Order 14398.
Activity has remained steady, ranging from 4 to 9 awards annually over the past five years, with 2025 showing 8 awards and 2026 (year-to-date through May) showing 4 awards. The recompete cliff is light: only 8 awards (combined potential value $2 million) reach ultimate completion within the next twenty-four months, indicating limited near-term recompete exposure. Eversource also holds one subcontract with the Massachusetts Institute of Technology on operation of the MIT Lincoln Laboratory Federally Funded Research and Development Center (awarded November 2025), subcontracting for utility electric services.
