Very interesting. I think you are right about the behavioural nudges based on the current timings for the tariffs. But if the peak period stretches until 19:30, or 20:00, would you still be prepared to wait to cook dinner? I get the principle of re-scheduling less time-sensitive things (eg as long as the car is charged for when you need it, it matters less when you charge it - or it’s unlikely to be a problem if you run your dishwasher or washing machine at night), but I’m more sceptical about readjusting one’s life around whatever happens to be that day’s energy pricing model.
