Grand Coulee Dam’s Third Powerplant saw a monumental lift on October 26, 2009 when one of the 600-megawatt generators was taken out of service for repairs. The nearly 2,000 ton rotor was removed from the generator and transported to the far end of the powerplant, where was stored while the repairs were completed. Watch the video: http://on.doi.gov/1Vd68A
