McCracken County, KY – Tennessee Valley Authority officials plan to shut down one of ten coal-fired electric generating units at McCracken County's Shawnee Steam Plant. Shawnee Unit 10 will be idled sometime next year to be evaluated for possible conversion to burning biomass fuel. TVA plans to do the same at eight other units throughout its multi-state network, reducing its generating capacity by 1,000 megawatts. The move is designed to reduce carbon emissions and improve air quality.
