How electricity bills and tariffs work in Spain
Every Spanish electricity bill has two usage charges — the capacity charge (potencia contratada, billed in €/kW/day for P1 peak and P2 off-peak hours) and the energy charge (kWh consumed × €/kWh) — plus the Bono Social discount if you qualify. On top of that the state levies the electricity special tax of 5.112696% and VAT (IVA) of 21%, and some suppliers bill a small daily meter rental. Consumers with 10 kW or less of contracted power (and a supply voltage up to 1 kV) can use the regulated PVPC tariff, where prices move every hour with the wholesale market; everyone else shops the libre mercado (free market) for fixed or time-of-use offers. Use this calculator to model flat and punta/llano/valle (2.0TD) tariffs side by side. Get Spain news in English every morning / Moving to Spain?

Frequently Asked Questions
How is a Spanish electricity bill calculated?
A Spanish bill stacks three charges: the capacity charge (término de potencia = P1 and P2 €/kW/day × days × contracted kW), the energy charge (kWh × €/kWh, either flat or split into punta/llano/valle periods) and any Bono Social discount. That subtotal is taxed with the electricity special tax of 5.112696%, the meter rental is added, then VAT (IVA) of 21% is applied to the result — the grand total is what you pay.
What is PVPC and do I have to use it?
PVPC (Precio Voluntario para el Pequeño Consumidor) is Spain's regulated electricity tariff for households and micro-enterprises with 10 kW or less of contracted power who haven't switched to the free market. Prices are indexed to the wholesale market and change every hour of every day. Everyone else is on the libre mercado (free market), where retailers offer fixed or indexed prices — this calculator lets you model either by entering the tariff rates yourself.
What is the difference between a flat tariff and punta/llano/valle?
Flat tariffs charge the same €/kWh at any hour. Punta/llano/valle (2.0TD) tariffs split the day into three periods: punta (peak, the most expensive hours), llano (shoulder) and valle (off-peak — nights and weekends, the cheapest). If you run washing machines, dishwashers or EV charging in valle hours, a time-of-use tariff usually wins; otherwise a flat rate can be simpler and cheaper.
What is Bono Social?
Bono Social Eléctrico is a state-funded discount on the energy part of the bill for vulnerable consumers: large families, low-income households, pensioners and people with disabilities. Reference suppliers apply the discount automatically once you register as a vulnerable consumer. In this calculator it is entered as a daily amount in €/day so you can model any percentage discount.
Which taxes are added to electricity bills in Spain?
Two taxes: the electricity special tax (impuesto especial sobre la electricidad) of 5.112696% applied to the sum of the capacity, energy and Bono Social charges, and VAT (IVA) of 21% applied last, on the total including that tax. Some suppliers also bill an optional meter rental (alquiler de contador / servicio de medida) of a few cents per day.
How much contracted power (kW) do I need?
Most Spanish flats contract 3.45–5.75 kW; family homes with oven, air conditioning and EV charging often take 7.3–10 kW. Contracted power drives the capacity charge — you pay for it every day whether you use it or not — so it is worth matching it to your real peak load. Undersizing leads to breaker trips; oversizing just costs money.
