About Ameren Services Company
Ameren Services Company, doing business as Ameren, is a for-profit utility services subsidiary of Ameren Corporation headquartered in St. Louis, Missouri, providing electric and natural gas utility services to federal facilities as a prime contractor across 159 recent awards with no set-aside designations. The vendor competes full-and-open across all customer agencies, with federal work concentrated in quarterly and monthly delivery orders for electric transmission, natural gas distribution, and utility infrastructure support at Bureau of Prisons facilities and Department of Veterans Affairs medical centers in the Midwest.
Ameren's federal customer base is heavily concentrated in regional correctional institutions. The top five customer agencies by award count account for 68% of recent awards, with the Department of Justice Bureau of Prisons accounting for 84 awards concentrated across three facilities: United States Penitentiary Marion (53 awards, $1.4 million combined potential value), Federal Correctional Institution Greenville (22 awards, $2.8 million), and Federal Correctional Institution Pekin (9 awards, $581 thousand). The Department of Veterans Affairs Veterans Integrated Service Network 15 carries 18 awards worth $6.8 million combined potential value. However, the dollar rankings diverge sharply from volume: a single General Services Administration Public Buildings Service Central Office Energy Division award valued at $50 million anchors 89% of Ameren's combined potential value across all federal work, signaling a major infrastructure contract alongside the recurring monthly and quarterly utility orders at correctional and VA facilities.
Ameren operates under two principal parent vehicles. Indefinite Delivery Contract 47PA0419D0001 carries 108 task orders worth $12.4 million combined potential value, primarily against Bureau of Prisons facilities. Indefinite Delivery Contract GS00P98BSD0109 holds 44 task orders worth $20.5 million combined potential value. Representative awards include a $1.13 million delivery order from Veterans Integrated Service Network 15 for electric and natural gas services at a Marion, Illinois facility (awarded October 1, 2024, with a $50 thousand funding increase authorized July 28, 2025), a $466 thousand delivery order from Defense Energy Information Service Kansas City for monthly electric utility service and connection setup at VA John Cochran Medical Center in St. Louis running through October 2035 (awarded October 10, 2025), a $344.9 thousand quarterly delivery order from Federal Correctional Institution Greenville for gas and electric utilities (awarded October 1, 2025), and a $90.7 thousand delivery order from VA Office of Construction and Facilities Management for utility relocation services supporting the Jefferson Barracks National Cemetery Sylvan Springs Development Project (awarded February 10, 2026). Routine quarterly and monthly awards to correctional facilities range from approximately $14 thousand to $120 thousand and represent the bulk of Ameren's recurring pipeline.
Activity has grown modestly over the past five years—from 16 awards in 2022 to a peak of 23 in 2025, with 10 awards year-to-date in 2026. Three awards worth combined potential value of $468 thousand face ultimate completion within the next twenty-four months, creating modest recompete exposure. Ameren has obligated $51.6 million against its combined potential value of $82.9 million (62% obligation rate), indicating substantial ongoing work. The vendor works exclusively as a prime contractor (100% of awards) with no subcontract footprint. Federal work falls almost entirely under NAICS 541512 (Electric Power Distribution) and PSC Utilities—Electric (107 awards) and Utilities—Gas (41 awards).
