In Germany there are already Smart Electricity suppliers which also provide a Wallbox in order to automatically charge your car whenever certain price threshold is reached. You could for example configure it to charge your car when prices are even negative. That's not so common anymore, but we had a price of -0.08€/kWh on 21.05.2021. 10 days ago, the prices were also pretty low (0.02€).

It can happen, as your examples show, but can it happen at scale, i.e. when 1 in 10 people are running "full house equivalent" energy requests every time the price drops below say 0.02 EUR/kWh? Been pricing electicity derivatives at work last week; with that context I'm now thinking of your scheme as a limit order, and what happens when the market is oversaturated with limit order?
