Side-by-side comparison of AI visibility scores, market position, and capabilities
Columbus OH multi-state electric utility (NASDAQ: AEP) ~$19.9B FY2024 revenue; 40K+ miles transmission, $54B 2025-2029 capex, Ohio AI data center load surge competing with Duke Energy and FirstEnergy.
About
American Electric Power Company, Inc. (AEP) is a Columbus, Ohio-based regulated electric utility holding company — publicly traded on the NASDAQ (NASDAQ: AEP) as an S&P 500 Utilities component — serving approximately 5.6 million customers across 11 states (Ohio, Texas, Indiana, Michigan, West Virginia, Virginia, Oklahoma, Arkansas, Louisiana, Kentucky, Tennessee) through subsidiary utilities including AEP Ohio, AEP Texas, Indiana Michigan Power, Appalachian Power, Wheeling Power, Southwestern Electric Power, and others through approximately 17,000 employees. In fiscal year 2024, AEP reported revenues of approximately $19.9 billion and operating earnings of $5.93 per share (approaching the upper end of guidance), as AEP executed capital programs supporting unprecedented load growth from AI data center development in its service territory — particularly in AEP Ohio (Columbus, Ohio data center corridor — one of the top-10 US data center markets with 800+ MW of contracted hyperscale data center load) and AEP Texas (West Texas commercial and industrial load growth). CEO Bill Fehrman (appointed late 2024, succeeding Julie Sloat) leads AEP's $54 billion five-year capital plan (2025-2029) — one of the largest capital programs in US utility history — focused on transmission expansion (building 765kV and 345kV high-voltage transmission lines to interconnect renewable generation and serve data center load growth), distribution system modernization, and regulated renewable generation additions that earn AEP's allowed return on equity across 11 state regulatory jurisdictions.
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.
