This is incorrect. It is not for a few minutes!

We are way way past that at this point. The renewable generation meeting the total demand is over most of the day. Because of solar PV, the cheapest generation now, the daytime electricity supply is actually more than we need in California. Solar farms (and also wind farms)get curtailed here due to supplying more than the grid can take at times; this is usually for several hours.

Those graphs clearly say that the state is pulling from non-renewable sources (primarily natural gas and "imports") between the hours of 7PM and 7AM. As I look at the page, right now (3:30AM local time), California is producing less than it needs, and the deficit is about 15,000MW. It isn't even close.

It's fine to say that California is producing more than it needs on net, but adding up total production over 24h and subtracting total consumption over 24h and seeing a positive value isn't meaningful if you're actually dependent on conventional sources for 12 hours a day.

But sure, it's more than a few minutes.

And given the incoming tidal wave of DER and cheaper storage that curtailment will stop I bet

> The renewable generation meeting the total demand is over most of the day

The article says renewable supply exceeded demand for “0.25-6 h per day”. This is great, but its not most of the day.
