Talen Energy Corporation
A U.S. independent power producer that runs roughly 13 gigawatts of power plants, anchored by the Susquehanna nuclear plant in Pennsylvania and a fleet of natural gas and coal facilities serving the mid-Atlantic grid. It sells electricity through long-term contracts, including a deal to supply carbon-free nuclear power to Amazon Web Services through 2042, and keeps two Maryland coal plants running under reliability-must-run agreements. The company is expanding its gas-fired baseload generation through acquisitions such as Freedom, Guernsey, and the pending Cornerstone deal.
