FranjaLuz: Spain Electricity

Check electricity prices by the hour, today and tomorrow, and decide when to use power. FranjaLuz shows you the PVPC price for every hour with official data from Red Eléctrica de España, and tells you when to run the washing machine, dishwasher or oven, or charge your electric car. No sign-up.

⚡ Electricity prices, today and tomorrow
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
See the current price and whether the hour is cheap, medium or expensive. Browse all 24 hours as a list or chart, find the cheapest hours and check tomorrow's prices as soon as they're published. Share the day's prices with one tap.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
📈 Tomorrow's price estimate
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Don't wait until 8:15 pm: from early morning you get an hour-by-hour estimate for tomorrow, refined by our algorithm using price history, the wholesale market and the solar and wind forecast. Set alarms on estimated hours and check “Estimated vs. actual” to see how close we get.

☀️ Self-consumption and surplus
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Got solar panels? Turn on Self-consumption and you'll see, in purple next to the consumption price, the hourly PVPC surplus compensation price, also for every day in History.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
🔌 Save with your appliances
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Add your appliances with their power and typical use. FranjaLuz estimates what each use costs, finds the day's cheapest slot and works out how much you could save per month. When you switch one on, follow its cost live.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
🔔 Alerts your way
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
We'll alert you when the cheapest or most expensive slot begins, when the price crosses your threshold, when a saved hour arrives or when tomorrow's prices are published, right on time or up to an hour early. Create your own reminders in “My alerts”, write your alert text and choose from five sounds.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
📍 Only in my zones
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Mark your home, work or other places on the map and we'll only alert you when you're in one of them. Your zones stay on your phone, with no location history.

⎯⎯⎯⎯⎯⎯⎯⎯⎯
🏠 Three widgets
⎯⎯⎯⎯⎯⎯⎯⎯⎯
A square widget with the current price and the cheapest hour left, a horizontal one with the nearby hours and a barometer that shows at a glance whether the hour is cheap, medium or expensive.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
📊 Price and generation history
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Review the last month, 3 or 6 months, the last year, everything since 2021 or your own dates: average, minimum, maximum, change from the previous period and hour-by-hour detail. Compare days side by side and discover which technologies generate the electricity, how much is renewable and how much CO₂ is emitted.

⎯⎯⎯⎯⎯⎯⎯
🎨 Your way
⎯⎯⎯⎯⎯⎯⎯
Mainland Spain, Balearic Islands, Canary Islands, Ceuta or Melilla; dynamic, light or dark mode; €/kWh or €/MWh; and Cheap/Medium/Expensive, Off-peak/Mid-peak/Peak or Trough/Plateau/Spike levels. In English, Spanish, Catalan, Galician and Basque, and offline with prices already downloaded.

Available as a monthly or annual subscription, or a one-time payment.

ℹ️ About the data
⎯⎯⎯⎯⎯⎯⎯⎯⎯
FranjaLuz shows prices for the PVPC, Spain's regulated tariff; the estimate is a forecast and the official price is the one that counts. Appliance costs are estimates: the app doesn't measure your actual consumption or replace your bill. The up-to-20% savings applies to a household that charges an electric car in the cheapest hours. On a free-market tariff, surplus prices depend on your contract.
