A $408 million emissions control retrofit project at the 528 MW Flint Creek coal-fired power plant in Arkansas was approved by the state Public Service Commission.
Southwestern Electric Power Co., a unit of American Electric Power (NYSE: AEP), owns a 50 percent stake in the plant along with the Arkansas Electric Cooperative Corp. SWEPCO must install the controls in order to comply with U.S. Environmental Protection Agency requirements to keep the plant running beyond April 16, 2016. SWEPCO was granted a one-year extension from the Arkansas Department of Environmental Quality beyond EPA’s 2015 deadline to continue plant operations if the company is in the process of installing the controls.
SWEPCO said construction on the project is expected to begin in January 2014. The utility will install a dry flue gas desulfurization system, also known as a scrubber; low nitrogen oxide (NOx) burners and overfire air, activated carbon injection and a fabric filter, commonly known as a baghouse. The controls will reduce emissions of sulfur dioxide, NOx, mercury and particulate matters.
