ABB won an order worth more than $100 million from the U.S. utility Los Angeles Department of Water and Power, to modernize the existing Sylmar HVDC (high-voltage direct current) converter station in California.

This station is an important part of the transmission link between the Pacific Northwest and southern California commissioned in 1970. The order was booked in the fourth quarter of 2016.

The Sylmar converter station, located to the north of Los Angeles, is the southern station of the Pacific Intertie, an 845 miles HVDC link that connects to the Celilo converter station near the Columbia River, along the border of Oregon and Washington.

The Pacific Intertie transmits electricity from the Pacific Northwest to as many as three million households in the greater Los Angeles area. Normally, the power flow is from north to south, but during the winter, the north consumes large quantities of power for heating while the south requires less, and the power flow is reversed. The Pacific Intertie allows power to flow between the Northwest and Southern California, helping to balance supply with demand.
