No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don't scale to countries.

California is doing pretty good with their battery storage. And if all the electric car batteries get old we can use them as stationary grid storage.

That is actually very impressive. Thanks! I remain a bit skeptical as its only 1/5th of what they need and it's only one region of one (rich) country. Still, 10GW of lithium battery would be one hell of a fire ;-)

South Australia implemented a 100mw battery for their power system in 2016

Overproduction is how you get blackouts from damaging the grid

Lol, just dump energy into resistors. Or desync two generators.

Or convert excess to hydrogen and provide resilience, or have arrangements for industry to consume the excess. Or ramp down your generation at those times. Or shift excess to neighbouring grids.

This is wrong. Right now, europe is experiencing high pressure and doesn't have any wind. Check this out its map that shows you how much wind is being produced right now! Can you provide a source that says " the wind is always blowing somewhere" or is it just a platitude?
