Already kind of in place. I’m on the Octpus agile tariff that gives different electricity tariffs every 30 minutes - with 24 hour notice if tomorrow’s prices.
Whenever electricity prices go negative I have automations to force-charge my solar batteries from the grid, turn on hot water heaters in my hot water tank (normally heated by gas etc. ).
