Allegheny Energy Remains Committed to Reduce Emissions at Coal-Fired Power Plants

---

Researched by Industrial Info Resources (Sugar Land, Texas). Allegheny Energy (NYSE:AYE) (Greensburg, Pennsylvania), whose coal-fired plants are among the nation’s heaviest polluters, continues to take steps to clean up emissions from its power plants. One of the most recent projects, on which construction is winding down, involved rebuilding an electrostatic precipitator (ESP) on the second unit at the Harrison Power Station (Haywood, West Virginia). For details, see related March 22, 2005 news article - Allegheny Energy Begins $40-Million Precipitator Rebuild at Coal-Fired Power Plant in West Virginia.

The Harrison Power Station consists of three coal-fired Foster Wheeler opposed-fired dry bottom boilers, each driving a 684-megawatt Siemens Westinghouse steam turbine/generator set. Unit #1 was completed in the spring of 2005 with the installation of the ESP. Allegheny Energy has scheduled the installation of an ESP on Unit #3 for the spring of 2007.

Allegheny Energy Supply Company, LLC (Monroeville, Pennsylvania), the power production subsidiary of Allegheny Energy, continues the practice by investing $360 million in scrubber technology to reduce sulfur dioxide (SO2) emissions on three units at its Hatfields Ferry Power Station (Masontown, Pennsylvania). The coal-fired power station consists of three Babcock & Wilcox opposed-fired dry bottom boilers, each powering an individual 576 MW Westinghouse steam turbine/generator set. Mechanical construction is scheduled to start this fall with one wet scrubber installed on each unit. Babcock & Wilcox Company (Barberton, Ohio) is contracted to construct the absorbers and vessels, while Washington Group International (Princeton, New Jersey) will be performing the balance of the plant work. Project completion is slated for the fourth quarter of 2008.
