Duke-American Transmission was formed in 2011 as a joint venture between Duke Energy and American Transmission to plan and develop transmission projects across the US and Canada.
The 84-mile transmission line, known as Path 15, connects California’s northern and southern transmission grids.
Path 15 is integrated into the California Independent System Operator (CAISO) grid and provides access to several California load centers.
In addition to Duke-American’s stake, Pacific Gas & Electric holds 18% in the transmission line and also owns and operates the connecting Los Banos and Gates substations.
Western Area Power Administration will hold the remaining 10% stake and will continue to operate and maintain the line.
Path 15, which was put into service in 2004, forms a part of the Pacific AC Intertie and the California-Oregon Transmission Project.
