- Constellation Energy Corporation Constellation Energy Corporation (CEG), headquartered in Baltimore, Maryland, operates as the nation's largest producer of carbon-free energy, generating more than 32,400 megawatts from a diverse fleet including nuclear, hydro, wind, solar, and natural gas facilities that supply approximately 10 percent of U.S. clean power; the company also serves as a leading competitive retail supplier of electricity, natural gas, and sustainable energy solutions to about two million residential, commercial, industrial, public sector, and institutional customers across the continental United States, including three-fourths of Fortune 100 companies, with annual retail volumes of roughly 150 terawatt hours of electricity and 800 billion cubic feet of natural gas. Core offerings encompass carbon-free power from over 19,000 megawatts of nuclear capacity across plants such as Braidwood, Calvert Cliffs, and Nine Mile Point; fossil fuel generation exceeding 12,000 megawatts from natural gas, oil, and combined-cycle facilities like Colorado Bend and Handsome Lake; hydroelectric output from Conowingo Dam and Muddy Run; wind power from 27 projects totaling nearly 1,400 megawatts; solar assets including Antelope Valley Ranch; energy management services via Constellation NewEnergy for procurement, brokerage, trading, hedging, and risk management; offsite renewables through the CORe program combining renewable energy certificates with load-following supply; sustainability solutions for carbon footprint reduction and 24/7 carbon-free matching; and technical services through subsidiaries Constellation Generation Solutions and Constellation PowerLabs. Founded in 1999 as a holding company by Baltimore Gas and Electric and spun off as an independent entity in 2022 following its separation from Exelon Corporation Exelon Corporation, Constellation conducts operations primarily in the U.S. with select international assets such as the Grande Prairie natural gas plant in Canada, targeting utilities, municipalities, cooperatives, hyperscalers, and end-users in deregulated markets. Recent developments include the January 2025 agreement to acquire Calpine Corporation Calpine Corporation in a $16.4 billion equity value cash-and-stock transaction, potentially creating the largest U.S. clean energy provider by combining nuclear expertise with Calpine's low-emission natural gas and leading geothermal fleets for enhanced coast-to-coast reliability and sustainability offerings; November 2025 securing of a $1 billion U.S. Department of Energy loan to restart the Crane Clean Energy Center, adding 835 megawatts of baseload nuclear capacity; senior leadership changes and integration of Calpine executives ahead of the deal's expected year-end closure; a 2024 power purchase agreement with Microsoft to reactivate Three Mile Island Unit 1; planned $3 billion in 2025 capital expenditures for nuclear uprates, life extensions, and battery storage; and issuance of a $900 million green note for eligible projects, all underscoring strategic expansion amid rising demand for dispatchable clean power.
