I'm on an unrestricted variable electricity tarrif.
My price per kwh is about to go negative for 3 hours*

I can get my oven and air con unit to fight each other, and be paid for it!

*it's so windy that there's nowhere to put all the energy the turbines are generating, so they pay (mostly industry) to use it up. The price shoots up in the evening when everyone starts putting their heating on and cooking dinner. People on a fixed price tarriff are paying ~25p/kWh all day in the UK right now.

Usually 24h in advance.
Beyond that, weather forecasts get too inaccurate to make any useful predictions about wind- and solar generation. (And demand is, to the delight of grid operators, quite predictable).

That doesn't stop hobbyists from concocting algorithms that try to make a whole week forecast, though. Here's one for the Dutch situation, for example: https://energie.theoxygent.nl/
