WNP-1 / 4 and WNP-2 ( now Columbia Generating Station ) should not be confused with the proposed Skagit/Hanford plant . Skagit/Hanford was a proposal advanced by a consortium of utilities led by Puget Sound Power & Light ( 40 % share ) and joined by Portland General Electric ( 30 % ) , Pacific Light and Power ( 20 % ) and Washington Water Power ( 10 % ) to build a two-unit plant north of Seattle in the Skagit Valley . The Skagit site was directly above a major earthquake fault . After the Three Mile Island accident in 1979 , Skagit County voters forced the consortium to relocate the proposed Skagit plant to the Hanford site . Skagit/Hanford had not progressed beyond the initial engineering design phases before the plant was scuttled . A 1978 Battelle Northwest report stated the Hanford site could support twenty or more nuclear reactors
