Columbia REA was formed in 1939 in Dayton, Washington – the gateway to the beautiful Blue Mountains. Today, Columbia REA is a progressive, strategically focused, member-owned electric cooperative that serves 4,600 customers in the southeastern corner of Washington. Columbia serves most of the new subdivisions in the Walla Walla area, as well as Walmart, Home Depot, and other retailers. They also serve Walla Walla University, in addition to significant irrigation loads that make up a sizable percentage of the cooperative’s kilowatt-hour sales.
