Widows Creek Power Plant (also known as the Widows Creek Fossil Plant) is a major 1600-MWe coal-fired power station, 4.8 miles (7.7 km) east of Stevenson, Alabama USA. The plant, operated by the Tennessee Valley Authority, generates about nine billion kilowatt-hours of electricity a year. It has one of the tallest chimneys in the world at 305 metres (1,001 ft), which was built in 1977.

History[edit]

Initially, six identical 140-MWe units were built between 1952 and 1954. Two more units (575 and 550 MWe name-plate capacity) were added in 1961 and 1965.[1][2]

Accidents and incidents[edit]

January 2009 gypsum slurry spill[edit]

On January 9, 2009, the plant experienced a dam break on a gypsum slurry pont, and spilled up to 10,000 US gallons (38 m3) of waste (possibly including boron, cadmium, molybdenum and selenium) into the creek of the same name on the property, inundating it with an ashlike substance.[3]

EPA compliance agreement[edit]

On April 14, 2011, the U.S. Environmental Protection Agency (EPA) announced a settlement with the Tennessee Valley Authority to resolve alleged Clean Air Act violations at 11 of its coal-fired plants in Alabama, Kentucky, and Tennessee.[4] Under the terms of the agreement, the entire Widows Creek plant will be affected:[5]

  • Units 1–6 will be retired in stages of two units per year, beginning by July 31, 2013 and ending by July 31, 2015
  • Units 7 & 8 will be fitted with selective catalytic reduction (SCR) devices to reduce their emissions of NOx
