The upgrade of the Celilo station included new transformers, valves, controls as well as switchgear and cooling equipment, the manufacturer said in a statement.
The Celilo converter, located near the Columbia River, is the northern station of the Pacific DC Intertie, a 1,360-kilometer HVDC link that connects to the Sylmar converter station in Los Angeles.
It transmits electricity from the Pacific Northwest to as many as 3,000,000 households in the greater Los Angeles area.
