    Why isn’t this as easy as storing some of that excess energy in a home battery and letting the rest down in a wire into the ground? Then if it’s smart enough it could only give back energy when needed.

      While water in pipes is often a metaphor for electricity, it’s not particularly useful here. You can’t ground out part of a charge. Energy storage is the solution though. Batteries are good, pumping water up back up into dams to be regained from a hydro plant when needed is ideal, as I understand it.

      Well, that’s what they’re doing some places. The batteries assets are not in private homes usually though, they’re by themself or run by power-consuming industries. Batteries are expensive though, and they degrade quickly if you use them wrong. In the EU, ENTSO-E defines the market rules, trade systems and messaging systems that energy companies and asset owners play by. Sometimes the revenue-generating asset is a battery, sometimes it’s a hot water boiler, wind park, factory, hydro plant etc.
