The company will request to decertify units 3 and 4 at Plant Branch; units 1-5 at Plant Yates; and units 1 and 2 at Plant McManus, all located in Georgia, by April 16, 2015, the effective date of the U.S. Environmental Protection Agency’s (EPA) Mercury and Air Toxics (MATS) standard. The units at Branch, Yates and Kraft units 1-3 are coal-fired generating units. Kraft Unit 4 is an oil- or natural gas-fired unit and McManus units 1 and 2 are oil-fired.
The company expects to seek a one-year extension of the MATS compliance date for Plant Kraft and retire those units by April 16, 2016. Additionally, Georgia Power will ask to decertify Boulevard 2 and 3 combustion turbine generating units upon approval of the Integrated Resource Plan.
Georgia Power will also request that units 6 and 7 at Plant Yates switch from coal to natural gas. Additionally, Unit 1 at Plant McIntosh will switch from burning Central Appalachian coal to Powder River Basin coal. The company also announced that the conversion of Plant Mitchell Unit 3 from coal to biomass cannot be completed before 2017 due to regulatory uncertainty related to the Industrial Boiler Maximum Achievable Control Technology rule.
Georgia Power received approval in March 2012 for the decertification of units 1 and 2 at Plant Branch, effective Dec. 31, 2013 and Oct. 1, 2013, respectively; and unit 4C at Plant Mitchell effective March 26, 2012. The three units total 602 MW of generating capacity.
The rest of Georgia Power’s coal-fired fleet are currently undergoing the installation of emission controls.
