How to choose the right tariff
Check your 'Potencia Contratada' — don't pay for more capacity than you need.
Analyze your usage hours — do you use energy during the day or at night?
Look for permanence — avoid contracts that trap you for 12 months.
Consider the 'Bono Social' — if you are a vulnerable household, the regulated PVPC is usually best.
Transparency & Market Rules
Freedom to Switch
Under Spanish regulations, domestic clients are generally free to switch electricity providers at any time without penalty. While signing up for a fixed tariff locks in your price (typically for 12 months), it does not lock you to the provider. You remain in control of your contract.
Dynamic Market Pricing
Energy offers in Spain change frequently, especially during times of market volatility. This is why you might find that a friend or neighbor who signed up with the same company has a different pricing structure than yours.
