Grid yes , maybe not the power plants themselves. Typically in robust networks you have good interconnects to neighbours you can purchase power from .

Also robust grid which enables selling back to the grid would have helped, such extreme hot weather goes in hand with solar generation

The problem is not lack of grid capacity. California is capable of importing upwards of 11 GW[0] but there was only around 8 GW[1] available yesterday because it's hot in neighboring states like Oregon too.

The load shedding occurred around 8-10pm after the sun has gone down (but while it's still quite hot) so more solar wouldn't help much.
