About
Eversource Energy is a Springfield, Massachusetts-based regulated electric and natural gas utility — publicly traded on the New York Stock Exchange (NYSE: ES) as an S&P 500 Utilities component — serving approximately 4.4 million customers across Connecticut, Massachusetts, and New Hampshire through electric distribution, transmission, and natural gas distribution subsidiaries including Connecticut Light and Power (CL&P), NSTAR Electric (Massachusetts), Public Service of New Hampshire (PSNH), and Yankee Gas through approximately 9,000 employees. In fiscal year 2024, Eversource reported revenues of approximately $11.7 billion, generating regulated earnings while executing a major strategic pivot: the sale of Eversource's offshore wind equity interests — South Fork Wind (132 MW, operational), Revolution Wind (704 MW, construction), and Sunrise Wind (924 MW, development) — to Global Infrastructure Partners for $1.1 billion, exiting the offshore wind development business entirely to refocus capital on the core New England regulated utility operations. CEO Joe Nolan's strategy of offshore wind exit reflects the economics reality of inflation-driven construction cost increases that made Revolution Wind and Sunrise Wind uneconomic at previously contracted power purchase agreement prices — fixed-price PPAs signed at $80-100/MWh before the 2022 inflation surge became deeply underwater when offshore wind construction costs escalated to $150-200+/MWh equivalent. The offshore wind exit releases $1.5+ billion in committed capital and eliminates the development risk that had pressured Eversource's investment-grade credit ratings.
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.
