Control systems would give the utility the ability to refuse excess power. So let's say exactly 100% of the power supplied to the grid is solar. If we control it at 100%, that's a good thing, right? But what happens when a storm comes in, and some percentage of solar power production is lost? The utility has milliseconds to make up the shortage. A rotating generator can't be started instantly from a dead stop. Somewhere in the system, turbines are rotating generators so that [power in] = [power out] can be maintained. Virtually instantly. As more storage systems are brought on line, the elasticity of the system is improved, but at some point, eventually traditional power plants must be spun up to keep the lights on. Plants have to be staffed and maintained to be ready to go at a moment's notice.
Oh, look, a pig just flew past the window.However, allegedly, it'll be complete in 2025
The idea that wind and solar HAVE to be used is not necessarily true. Turbines can be feathered and can't you just not use solar and it goes to waste?

But other options are being explored, like using your electric car as a storage reservoir. Charge it doing the day, and then use some amount of the stored energy during the evening and night.
Unless the inverter is the type that can be turned off by 'command central', which most of the older ones can't, means that to stop them feeding in power the grid voltage has to be raised.The idea that wind and solar HAVE to be used is not necessarily true ........ can't you just not use solar and it goes to waste?
