Frequently asked questions
Which is the best app for checking electricity prices in Spain?
redOS is the most reliable because it is published by Red Eléctrica, the operator that sets the price, although its interface is more technical. For daily use, Ahorra en Luz on Android and Precio Luz España on iPhone are more convenient thanks to their widgets and alerts. The data is the same in all of them.
What time is the next day's electricity price published?
Around 20:15, when the market operator publishes the auction result and Red Eléctrica calculates the PVPC for each hour. The apps show it shortly afterwards and some send an alert with the cheapest hours.
Are these apps useful if I am on a free-market tariff?
Only partly. Hourly pricing affects the regulated PVPC tariff and indexed free-market tariffs. If you have a fixed price with your supplier, you pay the same at any hour and these apps will not change your bill, although the time bands for contracted power still apply.
Which are the cheapest hours for electricity in Spain?
As a general rule, the early hours of the morning and the middle of the day, when solar output is highest, plus weekends. But the price is set every day at auction, so the only reliable thing is to check the app: there are days when the cheap hours change completely.
