P1, P2 and P3 Electricity Rates in Spain Explained
Peak, Shoulder and Off-Peak Tariffs Under the 2.0TD System
If you have an electricity contract in Spain, you have probably seen the terms P1, P2 and P3 on your bill. Most households do not fully understand what they mean. Yet these time bands directly determine how much you pay per kWh.
What Are P1, P2 and P3?
Under Spain’s regulated 2.0TD electricity tariff structure, the day is divided into three pricing periods:
- P1 – Peak (Punta): Most Expensive
- P2 – Shoulder (Llano): Mid-Level Pricing
- P3 – Off-Peak (Valle): Cheapest Period
Each period has a different price per kWh. This system applies to most residential electricity contracts in mainland Spain with contracted power up to 15 kW.
Time Bands Reference Table
| Period | Time Band (Mon-Fri) | Type | | :--- | :--- | :--- | | P1 (Peak) | 10:00–14:00 & 18:00–22:00 | Expensive | | P2 (Shoulder) | 08:00–10:00, 14:00–18:00 & 22:00–00:00 | Mid-Rate | | P3 (Off-Peak) | 00:00–08:00 & All Weekends/Holidays | Cheapest |
The Solar Shift: Why Midday is Changing
Spain now produces massive amounts of solar electricity between 12:00 and 18:00. Traditional tariffs treat these hours as expensive, but wholesale prices frequently collapse during these hours due to solar oversupply.
This is why innovative suppliers like Octopus Energy are adapting. We explain this in detail in our Octopus Sun Club guide.
