Project at a Glance
- Project Status: Active
- Location: Central California
Duke-American Transmission Co. owns 72 percent of the transmission service rights to the Path 15 transmission project, an 84-mile, 500-kilovolt transmission line in central California.
Path 15 connects the transmission grids between northern and southern California and plays an important role in maintaining regional electric system reliability and market efficiency. Path 15 is fully integrated into the CAISO grid and provides access to several California load centers.
Placed into service in 2004, Path 15 was a ground-breaking project that launched the competitive transmission industry by using private capital to fund much-needed new transmission infrastructure.
In addition to DATC’s ownership interest, Pacific Gas & Electric has an 18 percent interest in the transmission service rights and also owns and operates the connecting Los Banos and Gates substations. Western Area Power Administration owns the transmission line and the remaining 10 percent of the transmission service rights.
Approximately 1,500 megawatts
Operation and maintenance
