GenOn Northeast Management Co. was issued an air permit on March 30 to construct selective catalytic reduction (SCR) systems and associated equipment to control NOx emissions at the Conemaugh power plant located in Indiana County, said a brief notice by the Pennsylvania Department of Environmental Protection in the April 14 Pennsylvania Bulletin.
A reduction of PM/PM10, mercury, and sulfuric acid mist is also expected from this installation, the notice added.
The coal-fired Conemaugh plant is co-owned by eight parties. GenOn Energy (NYSE: GEN) said in its Feb. 29 annual Form 10-K report that SO2 scrubber upgrades and SCR installation are planned at Conemaugh over the 2012-2015 period, with its share of the costs for those projects ranging from $93m to $102m.
Conemaugh features two pulverized coal, supercritical boilers that total 1,700 MW and four diesel units with a total generating capacity of 12 MW. GenOn owns a 16.45% undivided interest in Conemaugh and operates the station on behalf of the owners through its wholly owned subsidiary, GenOn Northeast Management.
