Nuclear power is obtained for our customers via the South Texas Project (STP) located in Bay City, Texas. CPS Energy owns a 40 percent stake in STP (NRG Energy of Texas owns 44 percent, while Austin Energy owns 16 percent). STP units 1 and 2 generate 1,088 megawatts of power for our customers.
Because nuclear energy produces no greenhouse gas emissions it’s considered a clean-air energy. When compared to other generation staples like coal, natural gas or renewables, nuclear energy is considered more capable of meeting the demands of a customer base that is still growing.
