Power cut in Spain: electricity and gas emergency numbers and who to call

Updated on 26/10/2026 · Voltaris, independent energy advisers in Spain

When the power goes, almost everyone calls their supplier. But grid faults aren't the supplier's job: they belong to the distribution company in your area.

Distributor and supplier are not the same

Always check the number on your bill: your distributor's fault line appears next to your CUPS.

Before calling

Cut off for a returned payment or a contract in someone else's name? That's not a fault: we sort it out with your supplier and arrange reconnection, in English.

Frequently asked questions

Who do I call in a power cut in Spain?

The distributor in your area, not your supplier. In most of the province of Alicante it's i-DE: 900 171 171.

What's the difference between distributor and supplier?

The supplier sells you energy and bills you; the distributor owns the grid and meter and handles faults.

Where do I find the fault number?

On your bill, next to the supply details and the CUPS.
