MARSEILLES, Ill. (July 21, 2009) -LaSalle County Generating Station Unit 1 returned to the electrical grid at 5:33 p.m. CT Tuesday, July 21 after safely completing a maintenance outage.

LaSalle Station operators took Unit 1 offline at 5:52 a.m. Saturday, July 18 as part of a planned maintenance outage to replace a seal on a pump that circulates water through the reactor.

“The maintenance that we performed was successful and will ensure the continued safe, reliable operation of the unit,” said Dave Wozniak, site vice president.

During the maintenance on Unit 1, LaSalle Station’s Unit 2 continued to run at full power, producing carbon-free electricity for customers.

LaSalle County Generating Station is located approximately 75 miles southwest of Chicago. With both units at full power, the site produces more than 2,200 megawatts net, which is enough electricity for 2.3 million homes.
