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.
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.
