Average Electricity Costs for Restaurants in Spain

How much should you be paying?

Because restaurants run high-draw appliances continuously (industrial fryers, ovens, walk-in freezers, and A/C), their energy profile is uniquely punishing under the Spanish tariff system.

• Small Café / Tapas Bar: Typically requires <15kW of power (2.0TD tariff). Expect to pay between €300 to €600 per month depending on geographic location and A/C usage.
• Full Service Restaurant: Nearly always requires >15kW (3.0TD commercial tariff). Expect bills ranging from €900 to €2,500+ per month.

Note: If you are paying significantly more than this relative to your floor space, your contracted power (potencia) is likely set far too high, or you have rolled off your initial contract into a punishment-rate variable tariff.

The 3 Biggest Energy Mistakes Restaurants Make

1. Ignoring Maximeter Penalties

If your restaurant is on the 3.0TD tariff, your electricity meter acts as a "maximeter", meaning it records the highest 15-minute spike in power usage every month.

Many restaurants have a habit of turning on all appliances (ovens, fryers, grill extractors, A/C) simultaneously when preparing for service at 11:30 AM. This massive simultaneous draw creates a devastating spike in the maximeter reading, resulting in severe financial penalties on your bill—even if the appliances are turned off 20 minutes later. Staggering appliance start-ups by just 15 minutes can save massive amounts of money.

2. Nighttime Contracted Power (P6)

A restaurant's walk-in freezers run 24/7. This constant off-peak baseline load occurs during the P6 period (midnight to 8:00 AM). Due to the ascending contracted power rule (where P6 must be the highest contracted capacity), businesses often contract huge amounts of power for P6 unnecessarily, inflating their fixed daily costs by hundreds of euros every month.

3. Reactive Energy Fines (Energía Reactiva)

Industrial refrigerators, freezer compressors, and extraction fan motors generate "reactive energy" (power that bounces back into the grid). If this exceeds 33% of your active energy consumption in any period, the distributor automatically issues a massive penalty on your bill. Simply installing a capacitor bank (batería de condensadores) eliminates this line item entirely, paying for itself in a few months.
