COLUMBIA, S.C. (Jan. 10, 2008) – SCE&G’s Williams Station near Charleston and Cope Station in Orangeburg County are among the most efficient power plants in the United States, according to a recently published independent report.
The report, which appeared in the December 2007 issue of Electric Light & Power magazine, ranked two SCE&G plants among the nation’s top 20 coal-fired generating plants in terms of heat rate efficiency – a measure of how efficient a plant is at converting fuel to electricity.
Williams Station was ranked the 18th most efficient coal plant in the nation. Williams Station, which began commercial operation in 1973, employs more than 80 people and is the second-largest fossil plant in SCE&G's system. The plant generates 650 megawatts of electricity. At full load, the plant produces enough power in one hour to supply the average electric needs of 650 residential customers for one month. It can also generate 50 megawatts of electricity from two natural gas combustion turbines.
Cope Station was ranked the eighth most efficient coal plant in the nation. The report also ranked Cope among the top five coal plants in the United States for capacity factor – a measure of the amount of energy that a power plant actually generates compared to its maximum rated output. The newest fossil fuel plant in SCE&G’s system, Cope employs more than 70 people and generates 430 megawatts of electricity. At full load, the plant produces enough power in one hour to supply the average electric needs of 430 residential customers for one month.
