California Ramps Up Enough Battery Power to Match Five Nukes

5 "nukes" eh?
> The state now has enough large-scale batteries to supply 5,600 megawatts of electricity
Last I checked, batteries are measured in watt-hours. Ope, I just rechecked, they still are. Technically my car battery could produce 5,600 megawatts. Granted it might only do that for a femtosecond, but thats the whole point: 5,600 megawatts for _how long_? One minute, one hour?
Also last I checked, the Boobs by the Sea produced 2,200 megawatts of power. That [nearly] continuous power, not "until muh batteries run out". Yes yes, ramp up times, blah blah, refueling, ::hand waving::, xenon poisoning, ::more hand waving::
So congrats, 5.6gw of power storage _is_ awesome, but it's not "5 nukes" any more than 5 apples are the same as three lasers. I'm 100% behind these storage projects as they reduce the need for "peaker plants", but come on, lets at least a high schooler review these articles for scientific accuracy before going to press.

This is actually a serious amount of power storage

Technically it can't
Do people really shorten nuclear reactors to nukes?
Yes
(Preferably not by a company that tries to sell more batteries for their profit.)

TLDR Batteries get cheaper before your pumped hydro at scale gets built. It’s what’s playing out in Australia with “Snowy 2” currently. Similar to how you could never build nuclear as fast as solar (almost free at utility scale) and batteries, not as cheap (based on experience curves).
Batteries also provide grid services (maintaining voltage and/or frequency) within hundreds of milliseconds of detecting an anomaly, which simply isn’t possible with spinning mass due to inertia. This provides valuable grid services revenue (distinct from energy arbitrage).
