The utility industry has some serious work ahead to prepare for the emergence of plug-in electric vehicles from the development pipeline. Customers will be expecting high-voltage power in places where it’s not available today, like parking lots at the office. Customers will also need a way to pay for this electricity, with a new metering and billing system. In the long-run, a smart-grid that can pull power from vehicles, as well as charge them, could help smooth out the variation in solar and wind power.
It’s not surprising that one of the utilities working at the edge of electric car infrastructure is in California — the state leads in renewable energy and energy efficiency deployment as well. Southern California Edison isn’t blanketing its territory with upgrades, an unaffordable venture; rather, it’s using innovative measures to estimate where electric vehicles will be parked in the future and beginning the upgrades far in advance.
It’s refreshing to see forward thinking like this in the utility industry. Between the Smart Grid deployments funded by the recovery act and these preparations for electric vehicles, we’ll have much more flexibility to take advantage of renewable energy and next-gen vehicles in coming decades.

One utility that thinks it will: Southern California Edison. The utility covers a massive swath of land that includes 5 million meters, 14 million residents. By 2020, the utility’s customers could have up to 1 million EVs on the road. But SoCal Edison is already gearing up for the early adopters, explained Pedro Pizarro, the executive vice president of Power Operations for Southern California Edison. “If you have a block with three or four Priuses, that’s probably an early adopter neighborhood,” he said. SoCal Edison is in the midst of surveying its customers to find out which ones plan on buying EVs early. The zip codes with the highest amount of early adopters will likely receive upgraded wiring and circuitry that can handle all the excess pressure on the grid from EVs.
