>> You can have a stable power grid with ample supply and 0% "baseline" generation no problem (other than the usual generic ones).

Yes, if we have a future battery technology that can save a days worth of City's power consumption - something like this is phantom able.

With out sophisticated high capacity battery storage 'baseline' is a requirement.

Batteries are for diurnal leveling. You don't need 24 hour storage for diurnal leveling.

For long term or rare event storage, something like hydrogen will likely be cheaper. Efficiency is lower, but that's a good tradeoff to get lower per-kWh-capacity cost.

We're still a long way from diurnal leveling though. Currently CA's battery output can't even match a single nuclear reactor; it's currently outputting 459MW to Diablo Canyon's 1,140MW.
