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. https://www.newsweek.com/californian...es-ban-1738398
Yep, it’s gonna get toasty over the next 10 days in Sacramento. At one point the forecast was calling for 112 degrees on Labor Day!
The Newsweek article is a little exaggerated. Officials are asking folks to reduce energy usage between 4pm-9pm to relieve stress on the grid, which is wise so we avoid issues like Texas ERCOT. Very few EV owners are charging their cars between 4pm-9pm as it is. Majority of grid consumption will be AC and other appliances.
yea we are seeing excessive heat down in socal as well. this has always been a problem when it gets too hot for a long duration.
that's because socal is a desert!

agreed but with that heat, all a/c and refrigeration will be going full tilt.
So these morons enact a law forcing all new-vehicle buyers in the state to convert to full-EVs over the next dozen years, and then turn around and say please don't recharge them because we can't produce enough electric power when it's hot or cold?
And they were the first ones to laugh at the sensible persons who have been predicting for years that this would happen.

How much extra load are EVs putting on the grid, roughly in %.

That depends on a number of factors....hard to come up with a definite constant figure. But automotive hybrid or EV battery-packs, even with today's efficiency, still store and use a lot of electricity. It's not like simply recharging your cell phone LOL.

You must have some idea since you're blaming electric cars for power outages.
1) this isn’t due to any law. It’s a request, and a sensible one at that.
2) is it really that difficult to understand that prudent power management requests because of a heatwave this weekend and what the grid might look like thirteen years from now if the requirement to phase out new ICE sales does in fact come to pass are actually separate and unrelated issues?

The accepted best practice is NOT to charge your EV during the middle of the day when electricity rates are highest, due to demand. The load on the grid attributed to EV charging during peak hours is going to be minuscule as the majority of owners will charge at night. Sure some people traveling through the State will have no choice but to use fast DC charging at peak times but that’s a very, very small subset.
For years the solar on our roof generated enough electricity to offset our total usage during Summer months, leading to a negative bill. Our solar system fed the surplus generation back to the grid! However, we no longer run a surplus after adding a pool and EV, but it actually costs more per month to run the pool pumps than to charge the car (and we put 22K miles on the Model Y this past year). The stress on the grid comes from peak demand during daytime hours, and further compounded by hot weather. Electric vehicle charging is an extremely small proportion during peak demand, if anything you’d try to avoid charging during peak rates.
Well, people are being asked not to charge them, so somebody, somewhere must think they contribute to outages
Does somebody somewhere have actual data? Or are we going to discuss something somewhere somehow does a thing.
....so a quick search says about 75% of grid usage in California is heating, cooling and water. The rest is lighting, refrigeration and plug loads. I couldn't find more granularity that shows EV only plugin loads but at most it is a very small % of total grid load. It is not even close to being this:
