Duke Energy’s Edwardsport Generating Station is now operational.
Construction on the the 618-megawatt advanced technology coal gasification plant began in 2008.
The company says the Knox County operation is one of the cleanest coal-fired power-generating facilities in the world.
The plant uses advanced technology to gasify coal, strip out pollutants, and then burn that cleaner gas to produce electricity. The technology reduces the environmental impact of burning coal to produce electric power.
