Runs America's largest nuclear fleet — 13 reactors that produce 10% of all US carbon-free electricity, now signing landmark AI data center power deals that have made nuclear energy investable again.
Joseph Dominguez leads Constellation Energy, America's largest producer of carbon-free electricity, spun off from Exelon Corporation in February 2022. Constellation owns and operates 13 nuclear reactors across six states (Illinois, Pennsylvania, New York, Maryland, New Jersey, and South Carolina), producing approximately 10% of all carbon-free electricity generated in the United States. Constellation has become one of the most dramatic investment stories in the US energy market. The convergence of three powerful trends has transformed the company's outlook: (1) surging electricity demand from AI data centers, which require 24/7 reliable power, (2) corporate demand for carbon-free energy to meet sustainability commitments, and (3) the revaluation of nuclear power as essential to the energy transition. The landmark Microsoft deal — a 20-year power purchase agreement to restart the Three Mile Island Unit 1 reactor — epitomized this shift and sent the stock to record highs. Beyond nuclear, Constellation operates natural gas, oil, solar, wind, and hydroelectric generation assets and is one of the largest competitive retail electricity suppliers in the US. Key stock drivers include power prices, nuclear plant capacity factors, data center power purchase agreements, nuclear policy (production tax credits, regulatory support), the Three Mile Island restart execution, capacity market auctions, and the overall trajectory of electricity demand growth driven by AI, electrification, and reshoring.
