When is electricity cheapest?
Wholesale prices move hour by hour, and the gap between the cheapest and most expensive hour of a day can be large. Most household plans do not follow these prices directly; if yours passes wholesale prices through, shifting flexible use – charging an EV, running the dishwasher or heating water – into the cheap hours means paying the lower price for that energy. Either way, the hub price shows when power on the grid is cheapest. Prices in other zones.
