Celilo Converter Station, Oregon

One of the longest DC power transmission lines in the country begins here at the Celilo Converter Station. It was financed largely by the Los Angeles Department of Water and Power to deliver Columbia River energy to Los Angeles. Known as the Pacific Intertie, this line runs uninterrupted for nearly 800 miles to its other end, at a converter station in Sylmar, at the northern end of Los Angeles. The line has a capacity of 3,100 megawatts.
