Coal-fired power station in Georgia, US
The Robert W. Scherer Power Plant (also known as Plant Scherer) is a coal-fired power plant in Juliette, Georgia, just north of Macon, Georgia, in the United States. The plant has four generating units, each capable of producing 930 megawatts, and is the most powerful coal-fired plant in North America. The plant is named after the former chairman and chief executive officer of Georgia Power.[4]
Description
Each generating unit has a rated capacity of 945 megawatts, but produces 880 MW. The first unit was brought online in 1982. Additional units were brought online in 1984, 1987, and 1989.
It has two 1,001-foot (305 m) chimney stacks, one built in 1982 and the second in 1986. Based on data as of 2018[update], Plant Scherer is the fourth-largest electric generating plant in the United States, the largest to be fueled exclusively by coal,[5] and the number one emitter of greenhouse gas (GHG) emissions in the U.S., at over 20,000,000 short tons (18,000,000 t) per year.[6]
The plant's location is along the flight path of many commercial airline flights using Hartsfield-Jackson Airport in Atlanta, and is a prominent feature on the landscape, easily visible during daylight flights.
It was announced in June 2020 that Scherer will shut down Unit 4 by 2022 under an agreement reached by Florida Power & Light and the Jacksonville Electric Authority (JEA).[2] In November 2021, Georgia Power announced that Unit 3 would also close, this time by year 2025.[1]
Operator and ownership
The plant is operated by Georgia Power, a subsidiary of the Southern Company,[7]
along with Oglethorpe Power Corporation, the city of Dalton, Georgia; NextEra Energy (through subsidiary Florida Power & Light); JEA of Jacksonville, Florida; and the Municipal Electric Authority of Georgia.[8]
Coal trains
The coal used at the Scherer plant comes from Wyoming's Powder River Basin, and is delivered by Norfolk Southern to the plant by BNSF unit trains of up to 135 cars. Currently,[when?] at least two and as many as five trains a day are unloaded at Plant Scherer. The trains use a hydraulic dump system and are unloaded from the bottom of the cars while passing over the unloading trestle. They do not stop while unloading, and are usually unloaded in around 90 minutes. Train ID numbers are usually NS 732-739.[citation needed] Trains get on Memphis District via BNSF and on Atlanta District in Chattanooga.
Emissions
As of August 2012, Plant Scherer is under Georgia EPD investigation for coal ash pond leeching / drinking water contamination and air pollution / air quality. According to Natural History magazine, as of 2006[update] Plant Scherer is the largest single point-source for carbon dioxide emissions in the United States.[9] It was also ranked 20th in the world in terms of carbon dioxide emissions by the Center for Global Development on its list of global power plants in November 2007. It was the only power plant in the United States that was listed in the world's top 25 carbon dioxide producers.[10]
Regulatory policies and institutions
Since 2009 Lisa Jackson, Director of the Environmental Protection Agency (EPA) proposed controversial rules and regulations which include the Utility Maximum Achievable Control Technology rule and the Cross-State Air Pollution Rule.[11] Under CSAPR, non-complying plants like Scherer had only less than six months to implement required changes.
In 2011 Southern Company awarded KBR the contract for the installation of Plant Scherer's environmental compliance equipment, which included installation of flue-gas desulfurization and selective catalytic reduction equipment, related ductwork, and auxiliaries at two coal-fired units.[12]
As of 2010, KBR, Haliburton and other contractors had constructed two additional 847-foot (258 m) tall steam stacks for the Flue-Gas Desulfurization/scrubber.
