Best Time to Charge Your Electric Car in Spain
Spain's electricity prices swing by 200% between midnight and 7pm. Here's how to always charge at the cheapest window — and the three strategies that work best.
The difference between charging at PVPC peak (14–18 c€/kWh) and off-peak (6–9 c€/kWh) for one 60kWh weekly top-up = €4–€7 saved per charge × 52 weeks.

Note: Exact hours vary by distributor and season (winter/summer time). P3 is always overnight, typically 00:00–08:00.
The 3 Charging Strategies for Spain
Off-Peak Night Charging
RecommendedPlug in when you get home. Let your smart charger wait until the off-peak window opens. This is the simplest and most reliable strategy for most EV owners in Spain.
Solar Window Charging
RecommendedIf you have solar panels, charge your EV during peak solar production. Your EV acts as a solar battery buffer. Octopus Sun Club offers 4 free kWh per day for EV owners with solar.
Mixed / Smart Scheduled
Combine solar self-consumption with off-peak night charging. Start with solar priority (11:00–15:00), then top up overnight if needed. Requires a smart charger with schedule capability.

Smart Charging Tips
- Set your Wallbox or smart charger to start at 02:00 (not 00:00) — some P3 windows technically start at 01:00 or 02:00 depending on your distributor
- In summer, solar charging (11:00–15:00) can often beat even night rates — particularly in southern Spain
- Octopus Sun Club gives 4 free kWh per day for EV charging during solar hours — worth considering if you have solar
- If you drive >100km most days, a flat tariff like Octopus Go (€0.068/kWh flat EV rate) may be simpler than worrying about time discrimination
- Avoid charging to 100% unless necessary — for most daily driving, 80% is sufficient and better for battery longevity (see our Battery Guide)
Frequently Asked Questions
What is the cheapest time to charge an electric car in Spain?
The cheapest time is typically between midnight and 8am (Spain's P3/off-peak period), when PVPC rates drop to 5–9 c€/kWh. For solar panel owners, the period between 11:00–15:00 can be even cheaper or effectively free if you're using self-generated solar power.
Is it worth charging my EV with solar in Spain?
Yes — if you have solar panels, charging your EV during peak production hours (11:00–15:00) is the most cost-effective approach. With a 5kW solar system and a 60kWh EV, you can add 15–20kWh during a sunny day at near-zero marginal cost. Octopus Sun Club and other solar EV tariffs reward this behaviour.
Should I charge my EV at night in Spain?
If you're on a PVPC or time-of-use tariff, yes — night charging between 00:00 and 08:00 is typically the cheapest window. Octopus Intelligent Octopus Go specifically targets this window with a flat 6.8 c€/kWh rate. However, if you have solar, daytime charging may be cheaper or free.
What are Spain's P1/P2/P3 peak and off-peak hours?
Spain's PVPC tariff divides the day into three periods: P1 (peak, most expensive), P2 (mid-range), and P3 (off-peak, cheapest). Exact hours change seasonally but P3 is typically 00:00–08:00. On PVPC 2.0TD, P1 is usually 10:00–14:00 and 18:00–22:00. Your electricity distributor sets these hours — they follow REE (Red Eléctrica) guidelines.
Can I automate EV charging to use cheap rates?
Yes — with a smart home EV charger (Wallbox, Zappi, etc.) paired with a time-of-use tariff, you can set charging schedules to start automatically at your cheapest tariff window. Many smart chargers integrate directly with Octopus Energy's API to find the cheapest slots. This means you plug in when you get home, and the charger decides when to actually draw power.
