Duke-American Transmission completed its previously announced purchase from Atlantic Power of 72 percent of the capacity of Path 15—an 84-mile, 500-kV transmission line in central California that connects the state’s northern and southern transmission grids. Pacific Gas & Electric owns 18 percent of the line's capacity through its ownership and operation of the connecting Los Banos and Gates substations. The remaining 10 percent is owned by Western Area Power Administration, which will continue to operate and maintain the line.
