This is another view on what happened on Sunday in California. Batteries charged heavily throughout the day, soaking up the excess solar, approaching charging rates of 10 GW at times. In the evening, most of the output was centred on the early evening peak, but batteries supplied a significant share throughout the evening.
The biggest loser in this transition has been gas, with the share of battery storage staying at high levels throughout the evening peak. On Sunday, it stayed above 20 per cent of grid demand for almost four hours.
As Fulghum noted: “To put that kind of output during peak demand hours into perspective, it’s equivalent to the output from:
- 15-20 combined-cycle gas plants
- 6 Hoover dams
- More than the all-time peak demand of Portugal or Greece.”


Nice eval and analysis. I am finding it more and more obnoxious that lemmy doesn’t seem to like true debate. Take the down votes as a good sign that you struck a possible cord of reality.


It does. Missiles are $30k or £100k+
