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.
NJ's largest regulated utility with ~4.2M combined electric/gas customers; $9.8B FY2024 revenue; pure regulated utility after nuclear/fossil divestiture 2022-2024; $14B clean energy capex through 2026.
About
Public Service Enterprise Group (PSEG) is a diversified energy company and the parent of Public Service Electric and Gas Company (PSE&G), New Jersey's largest regulated electric and gas utility, founded in 1903 and headquartered in Newark, New Jersey, trading on NYSE (PEG). For FY2024, PSEG generated approximately $9.8 billion in revenues under CEO Ralph LaRossa, who has accelerated the company's strategic transformation toward a pure regulated utility model. The pivotal transactions of 2022-2024—selling its fossil fuel power plants to ArcLight Capital Partners and completing the sale of its 50% interest in three New Jersey nuclear plants (Hope Creek and Salem 1 and 2) to Constellation Energy—eliminated PSEG's unregulated merchant generation exposure and positioned it as a pure-play regulated utility.
