What the calculator does for you
Understand your bill
Every line in plain words.
Check tariff and contracted power
The tariffs from the official electricity comparison of the Spanish regulator (CNMC), calculated with your figures – and whether your contracted power is too high.
Solar for your own roof
Size, cost and payback as an estimate – also for existing systems.
How it works
To launch our service in November 2026, the first 99 evaluations are free; after that, 15 € for the detailed evaluation. You see straight away whether you can save on electricity and how much. If the saving is small, you are already in good shape. The detailed report names the right providers and tariffs; that is how we fund this service.
Who is it for?
For everyone who lives in Spain or spends part of the year here: families, retirees, sun seekers, home-office workers – and anyone who would rather understand a Spanish electricity bill in their own language. The calculator is designed for households on the 2.0TD tariff (up to 15 kW) on mainland Spain and the Balearic Islands. The Canary Islands, Ceuta and Melilla have different taxes and are not included.
Honest and transparent
- We compare all tariffs by what they would really cost you. No ads.
- Every figure with a source; results are estimates, not guarantees.
