The grid needs the supply and demand to be balanced for the power to be stable. Otherwise you get fluctuations in voltage and frequency which are both bad for anything connected to the grid.
There can absolutely be an oversupply of energy. We need to either find ways to store that surplus energy, or use it for something positive like desalination or carbon capture.
There’s been more solar and battery storage capacity installed this year+last year in USA than all prior years combined. And those investments are happening because the return of investment is huge. Those batteries are there to smooth out the supply and helps keep the grid stable.
