Southern California Edison (SCE), the large investor-owned utility serving Los Angeles and much of Southern California, recently released a white paper describing their growing experience with serving customers who own electric vehicles: "Charged Up: Southern California Edison's Key Learnings about Electric Vehicles, Our Customers and Grid Reliability".
According to the paper, SCE now serves more than 12,0000 customers having plug-in electric vehicles (PEVs). This represents about 10% of PEVs sold in the US. With this base of PEV customers, statistically useful empirical data is now becoming available - on PEV driving and charging habits, and associated grid impacts. According to the article, grid impacts of PEVs to date have been very manageable. A majority of PEV drivers are charging at home, using conventional 120-volt (wall socket) charging systems.
Less well understood are the potential impacts of higher-capacity charging systems now available in many battery-electric vehicles (BEVs).
Los Angeles, and even more so, the San Francisco Bay Area, are emerging as major centers of EV adoption. Ongoing analysis of driving trends, grid impacts, and charging services in these areas will continue to generate real-world learnings essential to growth of the PEV segment.
