We Make Carbon-Free Energy for 2 million Texas homes


The South Texas Project Electric Generating Station is one of the newest and largest nuclear power facilities in the nation STP's two units produce 2,700 megawatts of carbon-free electricity - providing affordable clean energy for more than two million Texas homes.


Our facility is located in the beautiful coastal community of Matagorda County, which is situated on the Texas Gulf Coast only about an hour southwest of Houston.


Our facility co-exists with the natural habitat and wetlands that are home to many animals, including alligators, deer and ducks. We worked with conservation groups to build and maintain a 110-acre Texas Prairie Wetland Project on our site.

Protecting Our Environment

Nuclear energy is the only large-scale source of carbon-free electric generation.


Nuclear power facilities produce electricity without emitting carbon dioxide or other greenhouse gases. It’s clean-air energy.


Nuclear power facilities generate about 70 percent of all clean-air electricity in the U.S.


The volume of greenhouse gas emissions prevented at nuclear power plants is equivalent to taking 92 percent of all passenger cars off America’s roadways.


Each year, the South Texas Project avoids the emission of approximately 16 million tons of carbon dioxide, 10,000 tons of nitrogen oxide and 38,000 tons of sulfur dioxide from polluting the air. Our facility safely delivers carbon-free energy to two million Texas homes every second of every day.


Since STP began commercial operation more than 20 years ago, it has been an industry leader in safety, reliability and efficiency. The two-unit facility consistently leads all U.S. nuclear plants in energy production.


At STP Nuclear Operating Company, we care about our environment.
