Document Description
The Power Plant 1 and Power Plant 2 Transmission Line Conversion Project (Project) is being proposed by the Los Angeles Department of Water and Power (LADWP) and would involve the demolition of an approximately 12-mile segment of an existing 115 kilovolt (kV) transmission line, and the construction of a new 230 kV transmission line. The new transmission line would also extend approximately 12 miles and would be located generally adjacent to the existing 115 kV line within an existing transmission corridor. The Project would begin at the Haskell Canyon Switching Station (HCSS) in the north and terminate at the Sylmar Switching Station (SSS) in the south. The purpose of the Project is to increase the transmission capacity between HCSS and SSS so additional renewable energy supplies can be transmitted to the Los Angeles basin.
