Spain Electricity Prices – PVPC & Spot, Hourly (REE) ⚡

Get the official hourly electricity prices in Spain straight from Red Eléctrica (REData API):

• PVPC 2.0TD: the regulated tariff that millions of Spanish households pay, hour by hour (energy, network tolls and charges, before taxes).
• Day-ahead spot market (OMIE, Spanish zone): hourly averages and, since October 2025, the 15-minute prices.

Today, tomorrow (as soon as it is published) or any date range since 2021, with the 2.0TD tariff period of every hour (peak, mid-peak, off-peak), its rank within the day, and the cheapest hours and time windows.

No scraping, no API key, no proxies.

What can you do with it?
