The San Luis Transmission Project is being developed jointly by a public-private partnership made up of Western Area Power Administration, San Luis & Delta-Mendota Water Authority, Bureau of Reclamation and Duke-American Transmission Co.

San Luis & Delta-Mendota Water Authority: A California joint powers agency responsible for operation and maintenance of the South of Delta Central Valley Project facilities. It represents 28 federal and exchange irrigation, M&I and wetland water service contractors within the western San Joaquin Valley, San Benito and Santa Clara counties.

Bureau of Reclamation: A federal agency under the U.S. Department of the Interior. It is the largest wholesale water supplier in the country and the nation’s second largest producer of hydroelectric power. In its Mid-Pacific Region, Reclamation owns, operates and manages the dams, power plants and canals of the Central Valley Project.

Western Area Power Administration: A power marketing administration within the U.S. Department of Energy responsible for marketing and transmitting more than 25,000 gigawatt-hours of clean, renewable hydropower annually from 57 federal hydroelectric powerplants owned and operated by the Bureau of Reclamation, U.S. Army Corps of Engineers and International Boundary and Water Commission in 15 western and central states. WAPA authorizes construction of transmission or may act independently to build transmission in the region.

Duke-American Transmission Company: A transmission developer equally owned by Duke Energy and American Transmission Co. Duke Energy’s regulated utilities serve customers in six states in the Southeast and Midwest. ATC is the nation’s first transmission-only utility. It owns and operates more than 9,600 miles of transmission lines and 554 substations in the Midwest. DATC owns 72 percent of the transmission service rights to the Path 15 transmission project, an 84-mile, 500-kilovolt transmission line in central California.
