Belews Creek Power Station

Belews Creek Steam Station is a 2.24-GW, two-unit coal-fired generating facility located on Belews Lake in Stokes County, North Carolina. It is Duke Energy’s largest coal-burning power plant in the Carolinas and consistently ranks among the most efficient coal facilities in the United States. During 2006, it was the fifth most efficient coal power plant in the United States with a heat rate of 9,023 Btu/kWh (37.8% conversion efficiency). The remaining 62.2% of energy released by the burning coal is in the form of heat. It is dumped into Belews Lake, a man-made lake created by Duke Power for cooling water purposes in the early 1970s. In 2008, it was the #1 most efficient coal power plant in the United States with a heat rate of 9,204 British thermal units per kilowatt-hour (2.697 kWh/kWh) or 37.1% conversion efficiency. In 2018 a complete redesign of the back-pass on Unit-1 significantly boosted this efficiency, ranking it the 2nd most efficient coal-fired power plant in the world. The plant consists of two nearly identical units, launched into operation in 1974 and 1975. Each furnace, a Babcock & Wilcox boiler, heats steam to 1,000 °F (538 °C) in both the secondary superheater and reheater sections. The boilers are supercritical units, operating at 3,400 pounds per square inch (230 atm) of pressure. All four generators (two low pressure generators and two high pressure/intermed
