PowerBill

PowerBill shows what electricity costs in Spain, hour by hour. Open it and the first thing you see is the price right now — and whether that is cheap, average or dear for today. No sign-up, no setup, no account. WHAT IT DOES • Now: the price this hour, with and without tax, and where it sits in today's range. • The day ahead: every hour as a chart, with the full list underneath. • Best hours: the cheapest window to run a washing machine, dishwasher, tumble dryer, water heater or electric car, and an estimate of what it saves against the priciest slot. • Compare: the regulated tariff against the wholesale market, side by side. • History: past days and months, so you can see how today compares. • Home screen widget: today's price without opening the app. • An optional notification when the cheapest hour of the day starts.
