Intertie (1969)

“Intertie” showcases the construction of the Pacific Northwest-Pacific Southwest Direct Current Intertie, a high-voltage electric superhighway between the Northwest and Southwest that helps balance power needs in the West and allows the two regions to share surplus electricity. It was the largest single transmission program ever undertaken in the United States. Construction began in the 1960s through a cooperative effort between public and private utilities in the Pacific Northwest and California. The 3,100-megawatt combined AC and DC transmission system was completed in 1970.
