SoCal Ed plans $561M Los Angeles basin substation upgrade
USA, California: Southern California Edison (SoCal Ed) is proposing to upgrade an existing Mesa substation in the Los Angeles Basin to 500 kV to help make up for the retirement of the 2,250 MW San Onofre nuclear plant and planned shutdowns of power plants that use ocean water for cooling.
USA, California: Southern California Edison (SoCal Ed) is proposing to upgrade an existing Mesa substation in the Los Angeles Basin to 500 kV to help make up for the retirement of the 2,250 MW San Onofre nuclear plant and planned shutdowns of power plants that use ocean water for cooling.
The Mesa loop-in project would expand an existing 230-kV substation by installing transformer banks, allowing the 500 kV Mira Loma-Vincent, 22 kV Laguna Bell-Rio Hondo and 220 kV Goodrich-Laguna Bell lines to be looped into the expanded substation to provide new transmission source lines and to distribute power toward coastal cities to the south, SoCal Ed said, according to Platts.
If approved, the $561 million Mesa substation project will increase import capability into the Los Angeles Basin, reducing the need to build power plants.
SoCal Ed plans to start building the Mesa loop-in project in April 2016 and finish it in late 2020.
