Mountain Creek Generating Station is a five-unit, 893-megawatt (MW) station located in Dallas, Texas.
The station provides power to customer in the Electric Reliability Counsel of Texas (ERCOT), when needed. In May 2003, an SCR (Selective Catalytic Reduction) system was completed on Unit 8. The system reduced Nitrogen Oxide (NOx) emission by 90 percent compared to 2002 levels.
The site’s original 34.5 megawatt, air-cooled generator, now retired, was built in 1938. Its first hydrogen-cooled, natural gas, 33-megawatt unit was built in 1945. When Unit 8 was added, it was only the second super-critical unit in the United States.
