Allegheny Energy Completes Clean Upgrade at Pleasants Power Station

Posted on: Thursday, 20 March 2008, 09:00 CDT

Pennsylvania-based electricity utility Allegheny Energy has completed a $105 million construction project to reduce emissions at its 1,300MW Pleasants power station located in Willow Island, West Virginia.

The project, which began in 2005, will remove an additional 30,000 tons of sulfur dioxide (SO2) emissions annually by sending 100% of the flue gasses through the station's flue gas desulfurization equipment.

Previously, only 85% of the flue gasses at Pleasants were scrubbed. The project is part of Allegheny's environmental stewardship initiative, which also includes installing scrubbers at its Fort Martin power station near Morgantown, West Virginia, and Hatfield's Ferry power station near Pittsburgh, Pennsylvania.

With the completion of these projects in 2009, Allegheny will reduce SO2 emissions by 70% from 2005 levels, reportedly transforming the company's power plant fleet into one of the cleanest in the US with respect to SO2 emissions.

The Pleasants project included installing new emissions monitoring equipment, fabricating new flue gas duct systems and constructing a 640-foot tall chimney.

In addition to reducing SO2 emissions, scrubbing all of the Pleasants' flue gasses will reportedly mitigate the periodic discharge of fly ash from the plant and reduce mercury emissions.
