Based on geotechnical reports, Crux expects to complete a total of 32 lattice tower foundations utilizing helicopter construction techniques.
DPV2 consists primarily of two new 500 kV transmission lines to be built within existing corridors. One 111-mile line will link SCE’s Devers Substation, near Palm Desert, with the Colorado River Substation, near Blythe. Another 42-mile line will connect the Devers Substation to SCE’s Valley Substation in Menifee. The project will connect solar energy rich areas of eastern Riverside County to the power grid and push California toward its 33% renewable energy goal.
Construction of DPV2 is currently underway and foundation work is expected to commence in March 2012. Crux will team with PAR Electrical Contractors, Inc. to construct transmission infrastructure for the project.
