Why Electric Vehicles Won't Break the Grid
Though conservatives have attacked California officials for asking electric vehicle owners to unplug during a heat wave, experts say more electric cars won’t topple the power grid
The spotlight on vehicle charging raised questions about whether the country’s electric grid would be able to withstand the accelerating transition to battery-powered cars, buses and other forms of transportation. If the grid was threatened by charging cars during this month’s extreme heat, how will it perform when EVs become present on every street?
But grid operators, utilities and clean energy advocates say it doesn’t make sense to blame electric vehicles for the soaring electricity demand during the recent heat wave. And in the future, as utilities make needed adjustments for widespread EV uptake, there’s no reason why transportation electrification should overburden the country’s grid, they said.In fact, experts see EV batteries as part of the solution.
They help to reduce planet-warming emissions and can add needed flexibility to electric utilities that are sure to come under more strain as global temperatures continue to rise.
Garrett Fitzgerald, senior director for electrification at the Smart Electric Power Alliance, called the backlash over California’s charging delays “undue criticism or panic.”
“The grid can handle it, we’re taking the necessary steps, but we’re just at the very beginning of putting those processes and programs in place,” he said. “A future grid will absolutely be able to handle a future demand of transportation electrification.”
