About
CMS Energy Corporation is a Jackson, Michigan-based regulated electric and gas utility holding company — publicly traded on the New York Stock Exchange (NYSE: CMS) as an S&P 500 Utilities component — serving approximately 6.8 million electric and 1.8 million natural gas customers throughout Michigan through its principal subsidiary Consumers Energy (Michigan's largest utility, serving 68 of Michigan's 83 counties) through approximately 7,500 employees. In fiscal year 2024, CMS Energy reported revenues of approximately $8.4 billion and adjusted EPS of approximately $3.29, growing within the company's 6-8% annual adjusted EPS guidance range that has made CMS Energy one of the most consistent earnings growth utilities in the US — delivering 18 consecutive years of meeting or exceeding earnings guidance under the management team's "CE Way" lean operational improvement program. CEO Garrick Rochow leads CMS Energy's strategy of executing a $20+ billion capital plan (2024-2028) focused on renewable energy generation (wind and solar replacing coal-fired generation ahead of the Michigan Public Service Commission's clean energy mandate), electric distribution grid hardening (replacing 1,750 miles of distribution lines annually to reduce storm outage frequency and duration), and natural gas infrastructure modernization. Michigan's Governor Whitmer's 100% clean energy by 2040 mandate (PA 235 — enacted 2023) requires Consumers Energy to retire coal plants, add significant renewable energy generation, and build battery storage — translating directly into approved rate base capital investment that earns Consumers Energy's authorized return on equity (approximately 9.9%).
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.
