About the company
Ameren Services Company, doing business as Ameren, operates as a prime contractor providing electric and natural gas utility services to federal facilities across the Midwest, competing full-and-open with no set-aside designations. The company is a subsidiary of Ameren Corporation, a St. Louis-based utility holding company, and holds a for-profit corporate structure with headquarters at 1901 Chouteau Avenue, St. Louis, Missouri.
Ameren's federal work concentrates on monthly and quarterly utility delivery orders—electric transmission, natural gas distribution, and infrastructure support—to Bureau of Prisons correctional facilities and Department of Veterans Affairs healthcare locations in Missouri and Illinois. Representative work includes a $346.8 thousand firm fixed-price delivery order issued October 1, 2026, by the Federal Correctional Institution Greenville for fiscal year 2027 annual gas and electric services running through October 15, 2027; a $1.13 million delivery order from Veterans Integrated Service Network 15 (awarded October 1, 2024, with completion through September 30, 2025) for electric and natural gas supply to a Marion, Illinois facility; and a $466.1 thousand order from the Defense Energy Information Service Kansas City (October 10, 2025, through October 9, 2035) for monthly electric utility service and connection setup at the VA John Cochran Medical Center in St. Louis. Ameren operates exclusively as a prime contractor with no identified subcontract footprint.
Customer concentration is heavily skewed toward Bureau of Prisons locations and the VA. The top five customer agencies account for 69% of awards by count: the United States Penitentiary Marion (55 awards, $1.4 million combined potential value), the Federal Correctional Institution Greenville (23 awards, $3.2 million), Veterans Integrated Service Network 15 (18 awards, $6.9 million), the Federal Correctional Institution Pekin (9 awards, $581 thousand), and GSA Public Buildings Service Region 5 (6 awards, $1.3 million). When ranked by potential value, the concentration profile shifts substantially: GSA Public Buildings Service Central Office Energy Division anchors 89% of combined potential value with a single $50 million award, followed by GSA Public Buildings Service Region 6 ($12.6 million across 6 awards) and VISN 15 ($6.9 million). This divergence signals that Ameren holds high-volume small orders from Bureau of Prisons and VA facilities alongside one major GSA centralized contract.
Ameren's task order activity flows through two parent indefinite delivery vehicles: Indefinite Delivery Contract 47PA0419D0001 (111 task orders, $12.9 million combined potential value) and Indefinite Delivery Contract GS00P98BSD0109 (44 task orders, $20.5 million). Work is coded predominantly to NAICS 541512 (Electric Power Distribution) across 112 awards, with secondary NAICS codes for utilities regulation and natural gas distribution. PSC coding runs 110 awards under Utilities–Electric and 41 awards under Utilities–Gas.
Over the past five years, award volume has grown from 16 awards in 2022 to a peak of 23 in 2025, with 13 awards recorded in 2026 (through October 15). Combined potential value across all 162 prime awards totals $83.4 million, with $51.7 million obligated (62% of potential). Only one award faces ultimate completion within the next twenty-four months ($347 thousand potential value), indicating minimal recompete exposure in the near term. The award footprint reflects sustained, recurring contracts typical of utility services to federal detention and healthcare infrastructure, with contract ceilings ranging from several thousand dollars for monthly billings to larger quarterly and annual agreements.
