About
Exelon Corporation is a Chicago, Illinois-based regulated electric and gas utility holding company — publicly traded on the NASDAQ (NASDAQ: EXC) as an S&P 500 Utilities component — serving approximately 10.2 million electric and gas customers across six regulated utilities: Commonwealth Edison (ComEd — Chicago and Northern Illinois), PECO Energy (Philadelphia and southeastern Pennsylvania), BGE (Baltimore Gas and Electric — Baltimore metro), Pepco (Washington DC and suburban Maryland), Delmarva Power (Delaware and Eastern Shore), and Atlantic City Electric (southern New Jersey) through approximately 21,000 employees. In fiscal year 2024, Exelon reported revenues of approximately $21.6 billion and adjusted EPS of $2.40, as the company managed through its first full year as a pure-play regulated utility following the February 2022 separation of Constellation Energy (the competitive nuclear generation business) as an independent public company — Exelon retaining only the regulated utility distribution and transmission subsidiaries serving Mid-Atlantic and Midwest metropolitan areas. CEO Calvin Butler (joined as CEO in November 2022) leads Exelon's strategy of executing the regulated utility capital plan: $34.5 billion in capital investment over 2024-2027 for distribution system upgrades, grid modernization, electric vehicle charging infrastructure, and regulatory compliance investments across the six utility service territories. Exelon's Mid-Atlantic service territory (Washington DC, Baltimore, Philadelphia, and Chicago) includes the densest concentration of federal government facilities, healthcare systems, and university campuses in the US — creating anchor commercial customers with high-reliability requirements that support premium rate case arguments.
Baltimore largest US nuclear operator (NASDAQ: CEG) at $23.6B FY2024 revenue; 21 reactors, Three Mile Island restarted Sept 2024 for Microsoft AI data center, 24/7 carbon-free power competing with Vistra and NRG.
About
Constellation Energy Corporation is a Baltimore, Maryland-based clean energy company — publicly traded on NASDAQ (NASDAQ: CEG) as an S&P 500 Utilities component with a market capitalization of approximately $70 billion — operating the United States' largest fleet of carbon-free nuclear power plants with 21 nuclear reactors at 13 generating stations across Illinois, Pennsylvania, Maryland, New Jersey, and New York, through approximately 13,000 employees generating approximately 10% of all clean electricity in the United States. In fiscal year 2024, Constellation Energy reported revenue of $23.6 billion. Constellation was separated from Exelon Corporation in February 2022, when Exelon spun off its power generation business as an independent company while retaining the regulated utility subsidiaries (ComEd, PECO, BGE, Pepco, Delmarva, Atlantic City Electric). CEO Joe Dominguez leads Constellation's strategy of capitalizing on the AI data center electricity demand surge — nuclear power's unique combination of 24/7 carbon-free reliability makes Constellation the preferred clean power supplier for tech companies' 24/7 carbon-free electricity commitments that intermittent wind and solar cannot fulfill. Constellation's landmark achievement was the September 2024 restart of Three Mile Island Unit 1 (renamed Crane Clean Energy Center) — the reactor that operated safely for decades before closing in 2019 due to economic competition from cheap natural gas — under a 20-year power purchase agreement with Microsoft to supply the data center campus supporting Microsoft's Azure AI infrastructure in Pennsylvania.
