California (CAISO) since January 2024.
In California, solar is up and gas is down.
California gas generation down 60% from 2024 as solar, imports surge
Solar generation in CAISO increased 21% from January through May compared with the same period in 2024, the Energy Information Administration said.

Banging on this that batteries met up to 44% of demand on the CA grid yesterday, roughly equivalent to 6 hoover dams. Cheap batteries are powering the grid. www.linkedin.com/posts/nicola...

CAISO nighttime gas usage is dropping to a couple percent. We're almost all renewable + some imports all day. California energy knowers, is the duck curve disappearing here?? We also just got daytime TOU rates that promote 10 am - 2 pm usage. 🔌💡

I also notice that Caiso and Ercot (the power grid areas for California and Texas) seem to have had good reliability years so far, despite extreme temperature conditions. Almost like solar and batteries help with that.

🔋Grid-scale batteries are replacing gas plants in CA’s evening energy peak!
On 3/29, CAISO batteries delivered 12.3 GW (43% of demand) during peak hours, sustaining over 20% of the grid for hours during the evening ramp
CA’s battery capacity has surged from 1.3 GW in 2020 to ~17 GW todsy

California’s renewables development is undeniably driving down emissions.
Chart below from CAISO data showing 2021-2024 emissions.
The increasingly deep drops in the spring and early summer is solar carrying the (often vast) majority of California’s grid.
It’s almost like renewables stuff works.

On 1 February 2026, batteries in CAISO never reached zero discharge rate while the sun was down, displacing gas and imports in California and supplying renewable electricity all night long.

SunZia, one of the world's largest wind power and transmission projects (3.5 GW), has started feeding power into California's CAISO.
New wind generation records are now being broken every other day.
The US should build on this clean energy leadership instead of abandoning it!

New record for batteries in California (CAISO) 🔋⚡
Yesterday, on the 20th May 2025, battery discharge crossed 10 GW for the first time.
That was enough to meet a THIRD of evening peak demand.
Solar moved fast, batteries are moving even faster...

Dang, like 1/3 of CAISO all-time peak and 2/3 of tomorrow's peak.
NEW: California now has nearly 17,000 megawatts of battery storage – reaching one-third of the way to our 2045 goal.
We're deploying more battery storage than any state in America, building a stronger grid, cutting pollution, and securing a safer future for our nation.
