> In the figure above, what was previously a defined peak in natural gas generation each evening has eroded into a plateau in 2024. That is because batteries are assisting with the predictable, but large, swings in solar output each day. These rapid ramps have been largely managed by natural gas units to date, but now batteries are taking on much of that responsibility.

- TheOtherHobbes 1y agoWhich is of course the answer. How much battery storage + renewables can you build for the cost of a nuclear plant? Especially given that prices are dropping. That's not even looking at solutions like pumped water, thermal storage, and others which have barely started ramping up to scale. These are all being built and used in Northern Europe. There's no magic here - just solid engineering and financing.

- Rebelgecko 1y agoOh cool, I've checked cal-isos supply graphs occasionally and looked again after reading your comment. It's the first time I've noticed there being times in the night where "battery" is the main source of electricity (albeit only for an hour or two, in the early morning it falls behind gas, hydro, nuclear etc). I'm sure that capacity is only growing going forward.
