Water Valley (formerly Lockhart) Substation Project

Click on the image above for a detailed map.

Southern California Edison (SCE) is committed to delivering electricity from renewable sources to the region’s power grid in order to help meet California’s goals for a clean, green energy future. To meet those important goals, SCE is proposing to build the Water Valley (formerly Lockhart) Substation Project near Harper Lake in San Bernardino County, California. The project will allow the Abengoa Mojave Solar Project to connect and deliver solar generation to the power grid. The project would also support the connection of future renewable generation projects in the area.

Project description

The Water Valley (formerly Lockhart) Substation Project will primarily consist of the following components:

Water Valley Substation – a new 220 kilovolt (kV) substation occupying approximately 10 acres of land on the Abengoa Mojave Solar Project site.
Transmission Lines – two parallel transmission line segments to connect the substation to the existing Coolwater-Kramer No. 1 220 kV transmission line.
Telecommunications - new facilities will be needed to connect the project to SCE’s existing telecommunications system, including the installation of 85 miles of new fiber optic communication cables on existing transmission line poles and on seven replacement poles, constructing new interest poles, placing segments of cable in existing underground conduit, and placing cable in new underground conduit.
