https://cleantechnica.com/?p=295135Senate bill 233 in the current session of the California legislature would require automakers to equip the electric cars they sell in the Golden State with V2G capability. At the present time, only the Nissan LEAF, Hyundai Ioniq 5, Kia EV6, and Ford F-150 Lightning have V2G systems their owners can take advantage of. By plugging them into bi-directional charging stations at home, EV owners can sell the power in those batteries to utilities during peak demand, buttressing the grid and reducing their utility bills.
“When the grid is stressed, wouldn’t it be great if instead of firing polluting fossil fuel peaker plants typically located in disadvantaged communities, we were using our electric vehicles?” said Kurt Johnson, community energy resilience director at the California nonprofit The Climate Center. “Even the smallest commonly available EV battery is a multi-day energy storage asset for everybody,” he told Canary Media. “A Nissan LEAF can run your house for days.”
California already has 1.5 million EVs on the road. By 2030, that number is expected to reach 8 million.
Combined, all the batteries in all those cars would have a total capacity of 80 gigawatts of power, Johnson said. That’s nearly 30 times the capacity of the state’s largest power plant, the Diablo Canyon nuclear generating station, which has a power output of “only” 2.3 gigawatts.
