Talen Energy Corporation is an independent power producer and energy infrastructure company based in the United States. The company owns and operates approximately 13.1 gigawatts of generation capacity, including nuclear, natural gas, and coal facilities. It primarily produces and sells electricity, capacity, and ancillary services into wholesale power markets such as PJM, ERCOT, and WECC. Talen's portfolio is anchored by the 2.2-gigawatt Susquehanna Steam Electric Station, a nuclear power plant in Pennsylvania. The company operates through two main segments: PJM, which encompasses its Mid-Atlantic generation and marketing activities, and ERCOT and WECC, which covers its Texas and Montana operations. In addition to traditional power generation, Talen is increasingly focused on supplying carbon-free electricity to data centers and digital infrastructure projects.
