$350 million committed for upgrades

Reliant Energy announced plans to install state-of-the-art emission control systems at two Pennsylvania power plants. Reliant Energy estimates it could spend up to $625 million through 2011 on sulfur dioxide (SO2), nitrogen oxide (NOx) and mercury controls at the company’s power plants.

The plans call for the installation of a wet flue gas desulfurization system, or scrubber, at the company’s Cheswick Generating Station in Springdale, Pennsylvania, and for funding Reliant’s portion of the scrubber installation at the Keystone Generating Station near Indiana, Pennsylvania.

Reliant estimates that its cost for the Cheswick scrubber and its portion of the Keystone project will be approximately $350 million. The scrubbers at both facilities are expected to begin commercial operation in 2009.

Installation of scrubbers at these units will remove approximately 98 percent of SO2 from the stations’ flue gases, reducing Reliant Energy’s SO2 emissions by approximately 68,000 tons per year. The systems will also be designed to maximize the removal of mercury.

In addition to the installation of scrubbers at the Cheswick and Keystone plants, the strategy includes upgrades to the existing flue gas desulfurization systems at Reliant’s Elrama and Niles plants. These upgrades will be completed this year and are expected to increase SO2 removal efficiency.
