About
Ameren Corporation is a St. Louis, Missouri-based regulated electric and natural gas utility holding company — publicly traded on the New York Stock Exchange (NYSE: AEE) as an S&P 500 Utilities component — serving approximately 2.4 million electric customers and 900,000 natural gas customers in Missouri and Illinois through two primary regulated subsidiaries: AmerenMissouri (electric and gas in Missouri, including the Callaway Nuclear Power Station — Missouri's only commercial nuclear plant) and AmerenIllinois (electric and gas distribution across central and southern Illinois), through approximately 9,000 employees. In fiscal year 2024, Ameren reported revenue of approximately $8.2 billion, with continued capital investment in transmission upgrades, distribution modernization, and renewable energy additions. Ameren Missouri's clean energy transition includes the announced Reform Renewable Energy Center — a 250-megawatt solar facility near the Callaway Nuclear site, with construction beginning in 2026 and expected to power 44,000 homes by 2028, creating 300 construction jobs. CEO Martin Lyons, who succeeded Warner Baxter in 2022, has maintained Ameren's steady capital investment trajectory targeting 6-8% annual EPS growth through infrastructure modernization and renewable energy additions in both states. The company's transmission infrastructure — spanning MISO (Midcontinent Independent System Operator) in Missouri and PJM Interconnection in Illinois — positions Ameren to benefit from grid investment programs enabling renewable energy integration across the Midwest.

About

Duke Energy is one of the largest regulated utilities in the United States with approximately $29 billion in annual revenue, managing a generation fleet spanning nuclear, natural gas, coal (transitioning to retirement), solar, and wind across a 100,000-square-mile service territory. CEO Lynn Good, who has led Duke Energy since 2013, filed the company's 2025 Carolinas Resource Plan responding to unprecedented load growth — North Carolina attracted $19 billion in announced business investments and 25,000+ new jobs in 2025 alone, driven by semiconductor manufacturing, data center construction, and electric vehicle manufacturing — resulting in electricity demand growth projections 8x greater than the prior 15-year trend. The plan calls for 4,000 megawatts of solar capacity by 2034 and battery storage expansion to 5,600 megawatts by 2034 (+2,900 MW from current levels).
