In the article "Hydroelectricity: The Versatile Renewable" (June 2009) the statement is made "...Grand Coulee Dam on the Columbia River in Washington State can go from low load to full load (about 800 MW) in matter of seconds." This is the capability of just one of three Canadian General Electric generators in Grand Coulee's Third Powerhouse. There are three other large Westinghouse generators in the Third Powerhouse. Their output is about 12 percent less than the CGE generators. In addition, there are two other powerhouses with 18 generators with outputs of about 125 MW when completely upgraded.
