Our utility provides 1:1 metering, so no storage is necessary (and the utility is primarily gas turbine supplied; every clean kWh we provide is some natural gas not burned). We’re self sufficient in the sense that we produce more power than we use. If net metering were to change to be less advantageous, the system was designed to accept one or more Tesla Powerwalls eventually; self consumption would then be prioritized (and I’d shift loads to daylight hours if the batteries were topped up) and drawing from the utility a last resort. Very common configuration in places like Australia, where distributed solar penetration is high and there is an abundance of renewables during daylight hours (causing the spot price of power to go negative much if the day).
In the meantime, it behooves myself and others for battery storage to be installed in places where the grid is far dirtier (remote communities, islands) where storage avoids burning diesel or bunker fuel (versus cleaner but not zero carbon natural gas).
(your comment history looks like you’re pro nuclear/anti renewables, so while I hope my comment was informative, I’m not interested in arguing the merits of net metering, rooftop solar, or nuclear vs renewables).
How much battery storage do you have? What does that cost these days?
