True. During heat waves the state and the grid operators will request that residents reduce their energy usage during peak hours, usually between 4pm and 9pm. That request also covers things like washers, dryers, and air conditioners. Most EV owners are already on time of use plans, which offers significantly reduced rates for charging overnight.Oops! California is already asking residents to not charge EVs during certain peak periods -- and this is with EVs making up only about 7% of the total vehicles in the state:
"Aug, 2022: owners of electric vehicles are being asked to avoid charging during peak energy usage hours in an effort to protect California's power grid."
With V2H, grid operators in the near future will have the ability to pay EV owners to make the energy in their EV batteries available during peak load to help the grid.
