Unit-level fuel conversion details:
Unit 1: Converted from coal to fossil gas in 2016.
Unit 2: Converted from coal to fossil gas in 2016.
Retirement of coal units
As part of a deal to end litigation regarding cost over-runs at the Kemper Project, Mississippi Power has agreed to cease coal operations at Plant Greene County and convert units 1 and 2 to natural gas no later than April 16, 2016.[5]
The plant stopped burning coal in March 2016 and was converted to run on natural gas by September 2016.[6][7]

Coal Waste Site
Greene County Plant ranked 30th on list of most polluting power plants in terms of coal waste
In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill.[8] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[9]
Greene County Steam Plant ranked number 30 on the list, with 1,343,973 pounds of coal combustion waste released to surface impoundments in 2006.[8]
