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.[1]

Two of the power lines run from Malin Substation (42°0′20.7″N 121°18′59.7″W / 42.005750°N 121.316583°W / 42.005750; -121.316583) southeast of Klamath Falls, Oregon to Round Mountain Substation northeast of Redding, California. One of them is owned by Western Area Power Administration, with the other owned by Pacific Gas and Electric and PacifiCorp jointly.[1] 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. The line was completed in 1993. [2]
