A complete expat guide to handling a corte de luz — who to call, how to claim compensation under Real Decreto 1955/2000, vulnerable-customer protections, and how home insurance covers spoiled food and damaged appliances.
A power cut in Spain (un corte de luz or apagón) catches almost every expat off guard the first time. The fridge stops, the WiFi router beeps, and the instinct is to phone Iberdrola or Endesa — except they're not the ones who can help.
This guide explains the single most important thing about Spanish electricity: there are two different companies behind every meter. The supplier (comercializadora) sells you the kilowatt-hours and sends the bill. The distributor (distribuidora) owns the cables, transformers and meters — and is the only company that can restore your supply when it fails. We'll show you how to identify your distribuidora, the exact numbers to call, how to claim compensation under Real Decreto 1955/2000 when an outage exceeds the legal limit, how to register as a vulnerable customer, and — crucially — how your home insurance covers the spoiled food and damaged electronics that result from a serious outage.
Coming from the UK, Ireland, USA, Australia or anywhere else, the Spanish system splits responsibility for the grid in a way that confuses every new arrival.
In most countries you have a single utility. Power goes off, you call the utility, they fix it. In Spain, the system was unbundled by law: one set of companies owns the wires (distribuidoras) and another set sells the energy (comercializadoras). You choose your comercializadora freely, but your distribuidora is fixed by geography — it depends on where you live, not on who issues your bill.
The national regulator is the Comisión Nacional de los Mercados y la Competencia (CNMC), and energy policy sits with the Ministerio para la Transición Ecológica y el Reto Demográfico (MITECO). The framework that governs outages, restoration times and compensation is Real Decreto 1955/2000, published in the Boletín Oficial del Estado.
Three things to know up front:
Six fundamentals every expat needs before — and during — a power cut.
Power outages are handled by the distributor (e-distribución, i-DE, UFD, Viesgo) — not by your billing supplier. Find your distribuidora on the top of any factura and save the number before you need it.
RD 1955/2000 sets continuity standards by zone (urban, semi-urban, rural). Exceed the annual hour limit or the per-incident limit and you may be entitled to automatic compensation on your next bill.
Where the distribuidora breaches the quality standards, compensation is calculated as a percentage of your annual access toll. The supplier credits it directly to your next factura — you usually don't need to chase it.
A standard Spanish hogar policy almost always includes "contenido del frigorífico" cover — typically €300–€900 for fridge/freezer contents lost in a power cut exceeding a defined number of hours.
An inexpensive UPS (sistema de alimentación ininterrumpida) keeps the router, modem and a laptop alive long enough to make calls. A small portable generator is sensible for rural fincas where outages can last days.
If someone in the home uses CPAP, dialysis, oxygen concentrators or other life-supporting electrical equipment, register with the distribuidora for priority restoration and avíso (advance notice) of planned works.
Whether you've just moved into a Spanish pueblo or you've been here years and just want to know if the apagón is worth claiming for, this guide is built for you.
Before the next outage hits, make sure spoiled food and surge-damaged appliances are covered.

Your distribuidora is determined by region — the legacy footprint of the pre-liberalisation utility. Even if your supplier is, say, Holaluz or Octopus, the wires into your home are owned by one of these five operators. You'll find the name printed on every electricity bill, usually near the top under "Datos del suministro" or "Datos técnicos".
| Distribuidora | Coverage | Outage Reporting |
|---|---|---|
| e-distribución (Endesa group) | Catalonia, Andalucía, Aragón, Balearics, Canaries, Extremadura | 900 84 90 84 |
| i-DE (Iberdrola group) | Madrid, Valencia, Murcia, Castilla-La Mancha, parts of País Vasco | 900 17 11 71 |
| UFD (Naturgy group) | Madrid (parts), Castilla y León, Galicia, parts of Castilla-La Mancha | 900 333 999 |
| Viesgo / e-redes | Cantabria, Asturias, parts of Castilla y León and Galicia | 900 101 234 |
| Distribuidores rurales locales | Small co-ops in Pyrenees, Maestrazgo, etc. | Number printed on the bill |
Put your distribuidora's 900 number into your phone contacts the day you move in, under "LUZ AVERÍAS" so it's easy to find at 3am when the lights are out and the screen is dim. These 900 numbers are free to call from Spanish landlines and mobiles, and the line stays open 24/7.
Before you call anyone, work through this short checklist — half of all "power cuts" turn out to be internal.
Operators classify outages with internal codes: programada (planned), imprevista (unplanned), fuerza mayor (force majeure — storms, fires) and incidencia en red (network fault). Only unplanned, non-force-majeure incidents count towards the legal continuity limits. Always ask which category your outage falls under and write it on your records.
Spanish law sets minimum continuity standards. Breach them, and the distribuidora pays you back automatically.
Real Decreto 1955/2000, of 1 December, regulates the transport, distribution, supply and authorisation of electrical energy installations. It defines two key continuity indicators for low-voltage domestic supply:
The zones — urbana, semi-urbana, rural concentrada and rural dispersa — each have different annual hour limits, reflecting the practical reality that a remote finca cannot be served to the same standard as a Madrid apartment.
How compensation is paid:
For damage to equipment caused by surges, brownouts or repeated trips, you can also file a reclamación por daños directly with the distribuidora. Keep purchase receipts, photograph the damaged item, and request the network event report (informe de incidencia) confirming the time, duration and cause.
If the cut was caused by an extraordinary event — a major storm declared "fuerza mayor", a forest fire, or a national-grid event like the April 2025 Iberian Peninsula blackout — the distribuidora is generally exempt from the continuity compensation. Equipment damage in those cases is what your home insurance is for.
If outages are a regular feature of your area, a modest investment can keep the essentials running.
UPS (Sistema de Alimentación Ininterrumpida) — A small box that sits between the wall socket and your equipment, with an internal battery. A 600–1000 VA model (€80–€180) will keep a router, fibre ONT and laptop running for 30–90 minutes — long enough for short outages, video-call rescue and orderly shutdown of desktops. Look for "line-interactive" or "online" topology and surge protection on the same unit.
Portable power station — Lithium battery stations of 500–2000 Wh (€400–€1,500) can power a fridge for several hours, charge phones for days, and run lights overnight. They're silent, indoor-safe, and pair well with a small solar panel for multi-day outages on a finca.
Petrol or diesel generator — Sensible for very rural properties where outages of 12+ hours are realistic. Sizing depends on demand: 2–3 kW covers a fridge, freezer and lighting; 5–6 kW will run a small heat pump or borehole pump. Generators must always be operated outdoors due to carbon monoxide, kept dry, and connected through a proper transfer switch (commutador de red) — never plugged into a wall socket.
Whole-home battery / solar self-consumption — If you already have, or are planning, photovoltaic panels, adding a battery (5–10 kWh) gives true islanding capability when the grid fails. The installation must be declared to the distribuidora and inspected.
If you do nothing else: buy a small UPS for the WiFi router, a powerful torch (linterna) and a head torch per family member, keep the boiler instructions in a drawer, and have a small camping gas stove for emergencies. Total cost: under €150.
A Spanish hogar policy is the single biggest reason a long power cut doesn't ruin you financially.
Most Spanish home insurance policies include — sometimes as standard, sometimes as a small add-on — cover for daños a alimentos en frigorífico y congelador. Typical sub-limits are €300–€900 per claim, payable when the supply is interrupted for more than a defined number of hours (usually 6) and the food becomes unsafe to consume.
In addition, most policies include daños eléctricos cover — paying out for appliances damaged by surges, voltage drops or lightning strikes that travel down the supply cable. Standard limits run from €1,500 to €6,000 per claim depending on policy tier.
How to claim — step by step:
Frozen meat for the year defrosting overnight? That's exactly what contenido cover is for.

Spanish distribuidoras maintain a register of supply points where the inhabitants depend on continuous electricity for medical reasons. Examples include:
Registration is made directly with the distribuidora, supported by a medical certificate from a public-health doctor. Once registered, you receive:
Separately, the Bono Social framework defines two further protected categories — "vulnerable" and "severely vulnerable" — based on income, family size or social vulnerability. Bono Social holders cannot have their supply disconnected during winter months for unpaid bills, and severely vulnerable households have additional municipal-funded protections. The two registrations are independent: you can hold both.
Medical-equipment registrations need updating every 1–2 years with a fresh certificate. Bono Social runs on a 2-year cycle. Set a calendar reminder six weeks before each expiry — letting it lapse can mean priority status is silently removed and the discount disappears from the next bill.
Different kinds of outage have different rules, rights and risks.
Planned maintenance (corte programado) — The distribuidora must give at least 24 hours' notice, displayed in the building entrance, on the distribuidora's website, and increasingly by SMS to registered customers. Planned outages do not count towards continuity compensation but you should still close the freezer, unplug sensitive equipment and plan around it.
Storms and weather events — Most rural outages follow Atlantic depressions and Mediterranean borrasca storms. Restoration is prioritised by hospitals, then larger centres, then rural feeders. Expect 12–48 hours after a major event in remote zones. If AEMET (the meteorological agency) declared a red weather alert and the cut is officially classed as fuerza mayor, the continuity rules pause.
National grid events — Spain experienced a peninsula-wide blackout in April 2025 lasting many hours, and subsequent investigations have focused on grid stability with high renewable penetration. These events are rare but real. Your contingency plan should not assume the grid is infallible.
Rolling load-shedding — In extreme generation shortfalls, the system operator can request the distribuidora to disconnect zones in rotation. Vulnerable-customer registration excludes you from voluntary load shedding wherever technically possible.
What to keep at home for a multi-day event:
After helping thousands of expats through Spanish outages, here are the six errors we see most often.
The questions expats ask us most often about Spanish power cuts.
Almost certainly your own consumer unit (cuadro eléctrico). Check the IGA, ICP and individual differential switches — reset them all in order. If the supply still won't restore and your neighbours are fine, the issue is on your side of the meter. You'll need a registered electrician, not the distribuidora. The distribuidora's only obligation is up to the boletín-certified end of your installation.
If the distribuidora has breached the RD 1955/2000 continuity limits for your zone, yes — it appears as a line item called "descuento por incumplimiento de calidad" or similar on a factura in Q1 of the following year. If you suspect you should have received it and haven't, raise it with the comercializadora first; they'll forward to the distribuidora. Persistent disputes can be escalated to the CNMC consumer-protection service or your regional industry directorate.
Most Spanish hogar policies include "contenido del frigorífico" cover, typically €300–€900 per incident, payable when an outage lasts longer than the minimum trigger (usually 6 hours) and food is rendered unsafe. You'll need the incidence number from the distribuidora, photos of the spoiled contents, and a list of itemised values. Check your particular policy summary — some entry-level products exclude this and require an optional rider.
Yes, in two possible places. Your home insurance's "daños eléctricos" cover usually pays for surge damage up to a defined limit. Separately, you can file a damage claim with the distribuidora — they'll investigate whether the surge was caused by a network event, in which case they may pay direct (or via their public-liability insurer). It's usually faster to go through your own insurer, who will then subrogate against the distribuidora.
The IGA (Interruptor General Automático) is the master switch for your installation. The ICP (Interruptor de Control de Potencia) limits how much power you can draw — it trips when you exceed your contracted potencia. The diferencial (residual-current device, RCD) trips when it detects a leak to earth — a wet appliance, a worn cable, sometimes a damp wall socket. Always test the diferencial monthly by pressing the test button; the IGA should drop instantly. If it doesn't, call an electrician.
Partially. Mobile masts typically have 4–12 hours of battery backup. Beyond that, coverage degrades. During the April 2025 peninsula blackout, many areas lost mobile data within hours, though voice calls and emergency 112 routing held longer. Keep an old 2G/3G handset with a SIM as a backup — they often connect when smartphones can't, and use far less battery.
The thresholds in RD 1955/2000 are zone-dependent. In broad terms, urban supplies have the tightest standards (only a few hours of cumulative unplanned interruption per year allowed) and rural dispersa supplies the loosest (much higher limits). The per-incident cap also varies. The CNMC and your distribuidora publish the exact figures — and your bill must show the compensation line if the limits were breached.
Two key clauses: contenido del frigorífico/congelador pays for spoiled food after an outage exceeding the trigger duration. Daños eléctricos pays for appliances damaged by surges or voltage events. Make sure both are present in your policy schedule before the next outage, and check the limits match your real exposure — a chest freezer full of meat is worth far more than the standard €300 entry-level limit.
The 900 number gets the lights back on — but it doesn't replace the meat in your freezer, the laptop your child was using when the surge hit, or the boiler that won't restart. A proper Spanish home insurance policy does. 247 Expat Insurance arranges DGSFP-regulated cover with full food spoilage and electrical damage protection, in plain English, for expats across mainland Spain, the Balearics and the Canaries.
