This is idiotic. The fact is your electricity transmission system operator has to pay a lot of money to keep the grid stable at 50 or 60Hz or your electronics would fry. With wind and especially with solar power, the variable output is always pushing the frequency one way or the other, and that creates a great need for costly balancing services. Negative pricing is an example of such a balancing service. Sounds good, but for how long do you think your electricity company can keep on paying you to consume power?
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.
