What dave says. Farm, Vehicle & Community Batteries will be like Gas Peakers coming online for Peak services, except Batteries are so much cheaper and renwable.
Main Grid will be WWS (Wind, Water & Solar) which will operate over 24/7 conjunctly.
Not sure why the angst about Community batteries as these will provide backup power in case the Transmission Lines cannot operate.
Electricity systems work on redundency. If one system fails another kicks in to replace.
