When is electricity cheapest?
Spot prices move hour by hour, and the gap between the cheapest and most expensive hour of a day can be large. If your contract passes through these spot prices, shifting flexible use – charging an EV, running the dishwasher or heating water – into cheaper hours can lower the energy-price component. Taxes, fees and your tariff still apply. Prices in other zones.
