This is also common in Denmark. You get the new estimated hour-by-hour rates around noon the day before. I actually made a little calendar subscription service[1] to help our household plan when to run the dishwasher, drier etc. and we've saved about 50% this quarter despite the rising electricity costs. You can usually tell when it's cheap/almost free too just by sticking your head out the window, since it's mostly always the cheapest on especially windy days.
