29 March 2006 - PPL Corporation is to build two cooling towers at its coal fired power plant in York County, US, as part of an agreement between the company and the Pennsylvania Department of Environmental Protection.
Bryce L. Shriver, president of PPL Generation said: "The cooling towers will help reduce river water temperature at times of the year when reductions will have the greatest benefits for fish and other aquatic life in the river."
PPL has been negotiating with the State Department for three years. Last December, investigators from the Fish and Boat Commission collected more than 300 dead fish downriver from the plant.
The 1485 MW Brunner Island plant uses water from the Susquehanna River for cooling purposes. According to PPL, the adding of cooling towers will remove the majority of the heat from the water before it is returned to the river, bringing it nearer to the original temperature.
Construction of the mechanical draft cooling towers is expected to begin by 2008, and the towers are scheduled to be in service in the Spring of 2010. The low-height, mechanical draft structures will stand about 50 feet tall, about one-tenth the size of the very large concrete structures often associated with power plant cooling towers.
PPL expects the capital cost of the cooling towers to be about $125m.
