GE Water presents LaSalle Station with ecomagination Leadership Award

LASALLE COUNTY, IL, Sept. 22, 2009 -- GE Water helped Chicago-based Exelon Corp. implement a new cooling-lake management strategy at LaSalle County Generating Station in Illinois. Implementation of this strategy has dramatically reduced the amount of carbon dioxide (CO2) used to treat the station's cooling water.

GE has selected LaSalle Station for a 2009 ecomagination Leadership Award.By implementing GE's ecomagination-certified phosphonate scale inhibitor technology, LaSalle Station significantly improved its equipment and helped soften cooling lake minerals. As a result of the successful implementation of the water treatment program, GE has selected LaSalle Station for a 2009 ecomagination Leadership Award.

Previously, LaSalle Station, part of the Exelon Nuclear fleet, had used carbon dioxide to treat its cooling water to suppress pH levels. As a result of this initiative, LaSalle has eliminated the use of 10,000 tons of carbon dioxide a year as compared to the station's 2001 baseline for consumptive use. Reducing this amount of carbon dioxide to treat LaSalle Station's cooling water is equivalent to taking nearly 1,700 cars off the roads.

"Climate change is a growing concern to utilities and other industries around the world, driving us to continually seek out creative, cost-effective applications that can help us further reduce the environmental impacts of energy production as much as possible," said Exelon Senior Vice President Midwest Operations Susan Landahl.

LaSalle Station implemented GE's advanced cooling water management program to enhance its regulatory compliance and reduce its energy and water "footprint." The project is part of the Exelon 2020: Low-Carbon Roadmap strategy to reduce, offset or displace more than 15 million metric tons of greenhouse gas emissions per year by 2020.

"As a longtime services provider for Exelon's entire fleet of boiling water reactor stations, GE is excited to partner with LaSalle Generating Station to showcase the environmental and economic benefits to be gained by implementing our advanced cooling lake water management program," said Heiner Markhoff, president of GE Water.
