Connecting the Country with HVDC | Department of Energy

Power is then transmitted over HVDC cables to a second converter station, which converts the power back to AC to be sent to end users. In 1970, the country''s first HVDC system—Pacific DC Intertie—was completed. This system enabled the delivery of low-cost hydropower from the Pacific Northwest to load centers in Southern California.
