California is going through a heat wave and as a result state energy regulators are asking EV owners to reduce charging from Aug. 31 to Sept. 6.
The California Air Resources Board recently approved a rule to require all new cars sold in California to be free of greenhouse gas emissions by 2035.
Californians may need to take measures to conserve energy, including by avoiding charging electric vehicles, to prevent strain to the state's power grid over the Labor Day weekend, officials said—a week after state regulators voted on a plan to ban the sale of gasoline-powered cars.
The new policy, approved by the California Air Resources Board, will require all new cars sold in California to be free of greenhouse gas emissions by 2035 as part of an effort to fight climate change.
But with a heat wave forecast for the coming days, California's grid operator on Tuesday warned that the excessive heat would stress the energy grid and conservation may be needed over the holiday weekend to avert power outages.
The California Independent System Operator said it issued an order restricting maintenance operations from August 31 through September 6 to ensure that all generators and transmission lines are in service.
In a news release, the California ISO said it expects that it will issue calls for voluntary conservation of electricity through Flex alerts over the long weekend.
"During a Flex Alert, consumers are urged to reduce energy use from 4-9 p.m. when the system is most stressed because demand for electricity remains high and there is less solar energy available," the release said.
The top conservation actions are to set thermostats to 78 degrees or higher to reduce air conditioner use, avoid using large appliances and charging electric vehicles, and turn off unnecessary lights, it said.
