Coal, Gas & Thermal — Sullivan County Indiana
Sullivan County has one of the most significant thermal generation histories in Indiana. The Merom Generating Station (1,080 MW coal) anchors the county’s energy identity. A wave of new natural gas generation projects has been proposed in the same corridor, driven by power demand growth and Merom’s proximity to existing 345 kV transmission infrastructure.
