A new 500 kV line called Devers - Palo Verde No. 2 (DPV 2) proposed by Southern California Edison (SCE) was approved by both the California Public Utilities Commission (CPUC) and California Independent System Operator (Cal-ISO) in the years 2007 and 2005, respectively. The new 500 kV line will follow the existing Devers - Palo Verde - 500 kV from Devers substation in the San Gorgonio Pass pass near Palm Springs in California to the Harquahala Generating Station (near the Palo Verde Nuclear Plant) in Arizona and will cost $680 million to build. The new line and associated upgrades to the regional transmission system will bring an additional 1,200 MW of electrical power to the Los Angeles area, which is enough to power 780,000 homes.
