About the company
Black Hills Service Company, LLC, operating as Black Hills Energy, delivers regulated electric and natural gas utility services to federal agencies nationwide as a prime contractor on full-and-open, non-set-aside basis. The company is a for-profit limited liability company and subsidiary of Black Hills Corporation, headquartered in Rapid City, South Dakota.
Black Hills Energy's federal footprint is anchored in recurring utility billings and long-term energy service agreements. The company operates predominantly under a single parent vehicle—Indefinite Delivery Contract 47PA0419D0014—which carries 60 task orders valued at $148.6 million in combined potential value. Representative recent work includes a $103.8 million delivery order from the Department of Veterans Affairs Technology Acquisition Center for utility energy services to VISN 23 Black Hills facilities (ultimate completion February 28, 2045), an $18.7 million Department of Energy Office of Science delivery order for electricity services at a facility in Lead, South Dakota (through December 31, 2035), and a $2.769 million Bureau of Indian Education delivery order for natural gas supply with base term and nine one-year option periods (through September 30, 2034). The company also holds a $50 million General Services Administration delivery order for utility services.
Customer concentration is extreme and skews toward recurring, lower-dollar-value contracts with a single dominant customer. The Department of Justice Bureau of Prisons Federal Correctional Complex Florence accounts for 45 awards (72% of total award count) valued at $19.4 million combined potential value—the vast majority consisting of monthly electric and natural gas utility billings ranging from approximately $150 thousand to $200 thousand per order. The top customer by potential value, the Department of Veterans Affairs Technology Acquisition Center, holds just one award but anchors $103.8 million of the portfolio's $198.6 million total. The top five customers by potential value account for 99% of combined potential value and represent the entire revenue concentration: VA Technology Acquisition Center, GSA Public Buildings Service Central Office Energy Division, Federal Correctional Complex Florence, Department of Energy Office of Science, and Bureau of Indian Education.
Activity has grown modestly year over year—10 awards in 2022 to 12 in 2025—with nine awards (combined potential value data not segregated by completion date in source) reaching ultimate completion by September 30, 2026 and potentially facing recompete. The portfolio's 62 awards across 13 distinct agencies carry combined potential value of $198.6 million, with $78.7 million (40%) obligated to date. Black Hills Energy operates exclusively as a prime contractor; the source reports zero subcontract awards. Work is performed nationwide with place-of-performance locations including Rapid City and Florence, Colorado; Lawrence, Kansas; Hot Springs, South Dakota; and Loveland, Colorado. All contracts are structured as firm fixed-price arrangements reflecting the predictable nature of regulated utility service delivery.
