Plan around your contract.

Q: What is the best time to use electricity in Spain?

It depends on your contract. A flat 24-hour price has no timing savings. Three-period plans use your peak, shoulder and valley rates. PVPC plans use Red Electrica hourly prices.

Q: Can I use it for EV charging?

Yes. Estimate the session length from the battery and charger, then compare times using your contract's prices.

Q: Is the estimated cost a full electricity bill?

No. The app estimates the effect of shifting flexible usage. Fixed or editable items such as contracted power, taxes, retailer margin, and social-bonus cost are kept separate.

Hourly electricity prices, EV charging, and flexible loads in Spain

Power Window uses your entered contract prices to plan flexible electricity use. It checks Red Electrica's hourly PVPC data when you choose an hourly plan.

What is the best time to use electricity in Spain?

It depends on your contract. A flat 24-hour price costs the same at every hour. With three periods or PVPC, the app compares the cost of available windows.

Can I use it for EV charging?

Yes. The EV planner estimates energy from battery size, current charge, target charge, and charger power, then estimates the session cost under your contract.

Is the estimated cost a full electricity bill?

No. It is an estimate for deciding when to shift flexible usage. Contracted power, meter rental, taxes, retailer margin, and other bill items can vary by contract and fiscal territory.
