More powerplants isn't the answer to ever increasing spikes. Powerplants can't ramp up & down very quickly, so addressing spikes with more powerplants just leads to more waste. And since we're talking reliable power at dusk, that means large co2 emissions & non-renewable, dirty fuel sources. Grid energy storage is increasingly critical. Distributing it to all the houses isn't really a bad idea for a battery-based solution. Pumped water is a great option for grid storage and is used throughout the world for that, but we are talking California here. Water is a precious & limited resource there.
