Duke-American Transmission to invest in California’s Path 15 transmission line

Duke-American Transmission Co. (DATC) has reached an agreement to purchase Atlantic Power Corporation’s interest in the Path 15 transmission project, an existing 84-mile, 500-kV transmission line in central California.

Path 15 has had a strong operating track record since it was placed into service in 2004. It is fully integrated into the California Independent System Operator (CAISO) grid. With a capacity of about 1,500 MW of power, the line provides access to several California load centers.

Under the terms of the agreement, DATC will acquire a 72 percent interest in the Path 15 transmission line. Pacific Gas & Electric has an 18 percent interest through its ownership and operation of the connecting Los Banos and Gates substations.

The remaining 10 percent interest in Path 15 is owned by Western Area Power Administration, which will continue to operate and maintain the transmission line.

Duke-American Transmission Co. is a joint venture between Duke Energy (DUK) and American Transmission Co. formed in 2011 to plan and develop strategic transmission projects across the U.S. and Canada.
