(Bloomberg) — Electrifying all new cars in California could be an immense burden on the state’s struggling power grid — or a whole new line of defense against blackouts.
It all depends on the time of day vehicles charge.
Governor Gavin Newsom’s executive order this week to phase out sales of new gasoline-powered cars by 2035 could add millions of electric vehicles to roads, driving up power demand as much as 9.5% in the next decade and 25% by 2035, according to estimates.
That could be a nightmare in a state where power supplies can be so tight on summer evenings that officials ordered rolling blackouts last month to prevent the system from collapsing during a heat wave. If millions of cars plug in at sundown, too, the problem may explode.
