The amount of battery storage required for a household on-grid is much smaller when you can think of the grid as a load balancing device.
Of course we'd need to get away from the huge mismatch between feed-in tariffs and consumption tariffs.
Ideally the difference would be a small spread (like in a currency exchange rate) and a nominal daily connection fee.
In which case a 10KW Tesla powerwall is a pretty handy size.

Maybe first we could nationalize the whole outfit and run it on a cost-plus basis. There is way too much profit being made from being a monopoly grid operator. That probably has more to do with why solar is such a good deal than the green energy subsidies do.

- ZeroGravitas 11y agoIn an optimally operating power grid, household storage should be pointless. If it makes economic sense for you to deploy batteries then you're probably dealing with a poorly regulated, or underperforming grid. The latter may simply be a matter of geography, but even then unless you live in a cabin in the woods then I believe e.g. in Australia some utilities are creating solar/battery/genset microgrids for remote communities, rather than try to maintain long power lines from the main grid.
