Pacific DC Intertie



Map of the route of the Pacific Intertie transmission route and stations

The Pacific DC Intertie (also called Path 65) is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). The line capacity is 3,100 megawatts, which is enough to serve two to three million Los Angeles households and represents almost half of the Los Angeles Department of Water and Power (LADWP) electrical system's peak capacity.

The intertie originates near the Columbia River at the Celilo Converter Station of Bonneville Power Administration's grid outside The Dalles, Oregon and is connected to the Sylmar Converter Station north of Los Angeles, which is owned by five utility companies and managed by LADWP. The Intertie can transmit power in either direction, but power flows mostly from north to south.

The section of the line in Oregon is owned and operated by Bonneville Power Administration, while the line in Nevada and California is owned and operated by Los Angeles Department of Water and Power.

The transition is at the Oregon–Nevada border, at 41°59′47″N 119°57′44″W.

This is one of two HVDC lines serving Los Angeles; the other is Path 27.

Path 27 comes n from the direction of Utah.

Path 66



Pacific Intertie transmission routes



A dual-circuit 500 kV line forming a part of the connection between Path 66 and Path 15.

California Oregon Intertie (COI), identified as Path 66 by Western Electricity Coordinating Council (WECC), is a corridor of three roughly parallel 500 kV alternating current power lines connecting the electric grids of Oregon and California. Their combined power transmission capacity is 4800 MW.

Two of the power lines run from Malin Substation southeast of Klamath Falls, Oregon to Round Mountain Substation northeast of Redding, California. One of them is owned by Western Area Power Administration, the other by Pacific Gas and Electric and PacifiCorp jointly. These lines are a part of Pacific AC Intertie and were completed in the 1960s. The third line runs from Captain Jack Substation near Malin to Olinda Substation south of Redding. It is a part of California-Oregon Transmission Project, the project manager is the Transmission Agency of Northern California (TANC), a joint venture of several public utilities. It was completed in 1993.

Route

Path 66 is composed of one segment of TANC, PG&E and PacifiCorp 500 kV lines. The TANC line route starts at Captain Jack Substation (42° 4' 38.06"N 121° 23' 25.47"W) close to Malin, close to the California-Oregon border, near the Malin Substation, where the other 500 kV lines start (PacifiCorp & PG&E). These substations link to both the PacifiCorp and Bonneville Power Administration (BPA) grid in the Pacific Northwest.
