PPL to Reduce Water Discharge Temperatures at Brunner Island Plant

PPL Corporation (NYSE: PPL) announced Monday (3/27) that it will install cooling towers at its Brunner Island power plant in York County as the result of a consent agreement between the company and the Pennsylvania Department of Environmental Protection.

“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,” said Bryce L. Shriver, president of PPL Generation.

“With the construction of cooling towers at Brunner Island, PPL is continuing its leadership in addressing the environmental impact of its generating plants while providing the energy that Pennsylvania needs to power its continued economic growth,” he added.

The Brunner Island plant uses water from the Susquehanna River for cooling purposes. Water that is returned to the river is warmer than when it was taken out of the river. The cooling towers will remove the majority of this added heat in the summer, when low river flows and higher temperatures have the greatest impact on aquatic life.

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. Shriver said these 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 $125 million, with the majority of those expenditures to be incurred in 2009 and early 2010. Based on its expectations for improving cash flows and a stronger balance sheet in those years, PPL does not expect to issue common stock to fund the capital expenditures for the cooling towers.

Shriver said the expected costs for installation and operation of the cooling towers do not alter PPL’s projected long-term compound annual earnings growth rate of 11 percent or its 2010 earnings target of $3.50 per share.

“The Brunner Island plant is a valuable economic asset for Pennsylvania,” he said. “PPL is committed to operating this plant - and all of our generating facilities - responsibly while minimizing the environmental impact.”

The 1,485-megawatt plant, which provides about 240 jobs, generated more than 10 billion kilowatt-hours of electricity in 2005, enough to supply the annual needs of about 1 million homes.

Last year, PPL announced that it was installing air emissions controls, known as scrubbers, at Brunner Island. The scrubbers, which will go into service in 2008 and 2009, will eliminate up to 97 percent of sulfur dioxide emissions from the plant, and will reduce emissions of mercury and fine particulate matter.

Combined, the cooling towers and scrubbers represent an investment by PPL of more than $900 million in environmental improvements at Brunner Island.

The consent agreement between PPL and DEP results from discussions regarding the plant’s water discharge permit. Similar concerns about the plant’s water discharge had been raised by Citizens for Pennsylvania’s Future. Also as part of the consent agreement, PPL has agreed to fund more than $183,000 in community environmental projects, will conduct studies of the biological effect of temperature changes in river water, and will continue biological studies of the river in areas around the plant’s discharge channel to determine the effects on animal and plant life of cooling the plant’s discharge.

PPL Corporation, headquartered in Allentown, Pa., controls about 12,000 megawatts of generating capacity in the United States, sells energy in key U.S. markets and delivers electricity to more than 5 million customers in Pennsylvania, the United Kingdom and Latin America.
