Nuclear: An Ideal Foundation for Our Clean Energy Future

South Texas Project Electric Generating Station (STP) is a 2,645-megawatt, dual-unit nuclear plant located about 90 miles southwest of Houston. Constellation owns 44 percent of STP (1,100 MW), producing enough carbon-free electricity to power the equivalent of more than 860,000 homes. Constellation is one of three owners with oversight of the South Texas Project Nuclear Operating Company (STPNOC), which operates the plant.
