Anyone can go on the Octopus Agile tariff here in UK, where you pay exactly what the prices are. If the prices are negative, then Octopus actually credits your account. I know some people with EVs on the Agile tariff, they have their car chargers set to only charge when the price is <0 - which happens at least a couple times a week, and they effectively get paid for charging the electric cars. Personally I'm on their GO tariff which guarantees 5p/kWh at night which I prefer because I charge my car every night so I can't wait for negative pricing.

> which happens at least a couple times a week,

Citation needed. Last time I looked the pricing of octopus agile went negative for like 15 minutes a year...

EDIT: just crunched the data... It looks like this only happened frequently in 2020 (not in 2018/19/21), and even then, for a typical 1 kilowatt household, it would only save £2 per year, and even if you deliberately maxed out and used the maximum current limit of your AC supply (100 amps, 24 kW, for most households), it's still only a saving of £50, which doesn't pay for the effort really...

You're absolutely right, it was far more common last summer when I was switching, looks like this year the negative prices are very very rare:

This is why it should be done on an organisational level: a company provides a service that makes sure that the car charger is enabled only at times with negative prices, and then makes money on providing a certain guaranteed load.
