"#Batteries the biggest player again as renewable records smashed in #California, reach 156 pct of load
Last week battery storage became, for the first time, the largest supply source in the evening peak of what is one of the world’s largest grids. On Tuesday, it discharged more than 6 GW for the first time, providing up to a 25 per cent share of supply, and was the biggest provider on the grid for two hours."
"The records continue to tumble in #California, one of the world’s biggest state grids, with #BatteryStorage playing an increasingly dominant role soaking up solar in the middle of the day and shifting it to the evening peak, where it is now regularly the biggest single supplier."
If you look at the figure in the article, you will see that at the evening peak batteries delivered about 6.5 GW, and apparently long enough to tide the system over for the evening.
It's not seasonal storage, but it's a start, One thing it certainly does is provide frequency stabilisation and the shaving off the peaks (both in demand and in spot price). And they're not yet done building them.
@CelloMomOnCars This is the way to do it. A bit of everything. Wind, Solar, Hydro, Nuclear, Batteries, grid investment, wide area HVDC interconnects, demand management, dispatchable demand, electrification of fossil fuel systems and so on.
Should be enough to keep Business As Normal going for a while longer yet.
@CelloMomOnCars Certainly ironic and sarcastic! It gets me in all kinds of trouble. /s
Still trying to understand what "managed degrowth" might look like. When our current global system is all about paying for the present by borrowing from the future. Meaning growth is assumed and without it all the debts will come due.
Much more likely is that some time later this century degrowth will be forced on us rather than managed. Degrowth is already here. It's just not evenly distributed.
Yes. Or as the kids, say, "Change will come, whether you like it or not."
The trick is to effect the change you like. The current rat race is not a great way to live, anyway.
"#Battery storage in #Victoria continues to displace gas as a provider into the evening peak, with more than 200 MW of battery output on Saturday night, and zero from the state’s peaking gas generators. Battery storage often supplies more into the evening peak than the gas generators, particularly at lower peak prices."
We are probably underestimating the potential for battery storage.
The assumption that it is not the appropriate technology for longer term storage was I think based on cost but the cost reduction with Na-ion batteries suggests that a whole lot more battery storage can be built.
Residential seems to be under-emphasised in general. Given changes to net metering tariffs (quite apart from grid unreliability), it really makes sense for Californians to pair solar installations with batteries, and for California to subsidise them.
And then to better support residential B2G for “staggered" delivery.
