Ameren Illinois Company (NYSE: AILLM), a subsidiary of Ameren Corporation, operates as a rate-regulated utility delivering electric transmission, electric distribution, and natural gas distribution services to customers across central and southern Illinois; its core offerings encompass reliable electric generation infrastructure, high-voltage transmission lines at voltages including 345kV, 230kV, 161kV, 138kV, 69kV, and 34.5kV, extensive distribution networks serving residential, commercial, and industrial users, and natural gas delivery systems supporting over 900,000 customers in a 64,000-square-mile area that includes cities such as East St. Louis and surrounding suburbs. Founded in 1902 as Central Illinois Public Service Company and renamed Ameren Illinois Company in October 2010, the company maintains headquarters at 10 Richard Mark Way in Collinsville, Illinois, with approximately 3,108 employees focused on the electric and other services combined industry. In recent developments, Ameren Illinois received Illinois Commerce Commission approval in July 2025 for its Central Illinois Grid Transformation Program, a major initiative involving 380 miles of new and upgraded transmission lines across 13 counties to enhance grid reliability, increase capacity for renewable energy integration, and support economic development; construction commenced later in 2025 following the regulatory green light. Additionally, in January 2025, parent company Ameren Transmission Company of Illinois secured selection by the Midcontinent Independent System Operator for $1.3 billion in critical transmission projects spanning Illinois and Missouri to bolster resiliency and clean energy delivery, while the company advanced energy efficiency programs offering incentives for lighting, HVAC upgrades, water-saving devices, specialty equipment in sectors like manufacturing and agriculture, and technical services such as retro-commissioning and strategic energy management; in late 2025, over 5,000 residential customers benefited from $300 financial relief credits stemming from a market manipulation settlement.
