How to Prepare for a Future Blackout in Spain

Although there's currently no concrete evidence suggesting that Spain will face another nationwide blackout in the near future, the recent outage caught many of us completely off guard. Given the uncertainty surrounding the cause, it's wise to take a moment to prepare—just in case history repeats itself.

No Matter the Cause, the Lesson Is Clear

Spanish authorities have yet to determine what triggered the latest power failure, leaving the door open for future risks. One thing is certain: the event exposed how deeply our homes, businesses, and daily routines rely on uninterrupted electricity, mobile networks, and internet connectivity.

This unexpected situation served as a wake-up call for many, highlighting how quickly daily life can come to a standstill without power. Fortunately, preparedness experts around the world have long compiled lists of essential items to have on hand in emergencies like these.

What to Have Ready: Your Blackout Preparedness Checklist

Being prepared doesn’t mean being alarmist—it means being practical. Here’s a comprehensive list of supplies worth keeping at home or in your office, in case of another power cut:

Flashlights (battery-powered) – ideally with a backup in case one fails.
Alkaline batteries – stock a variety of sizes.
Portable power banks – solar-powered versions are especially useful for charging mobile devices.
Battery-powered radio – FM/AM radios are useful to receive updates when the internet is down.
Long-burning candles
Matches and lighters
Dry powder fire extinguisher (ABC rated) – essential if you’re using candles.
Gas camping stove – useful if your kitchen relies entirely on electricity.
Electric generator – especially helpful for those with specific personal or professional needs.
Fuel canister and fuel reserves – for generators or vehicles.
At least one month’s supply of prescription medication
Basic first aid kit – including antiseptics, bandages, and over-the-counter pain relief.
Sleeping bags and thermal blankets – in case you need to evacuate or heating is affected.
Cash – if card machines go offline, you’ll need physical currency.
Multipurpose penknife
Non-perishable food – such as canned goods and long-life snacks.
Pet food – if you have animals at home.
Drinking water reserves – vital if water services are interrupted.
Weather-resistant clothing and sturdy footwear
Waterproof backpack – to carry essentials if needed.
Books, board games, cards – to keep everyone entertained while offline.

Many of these items can be found in large supermarkets like Carrefour, hardware stores (ferreterías), home improvement retailers like Leroy Merlin, or outdoor shops such as Decathlon.

What to Do During a Blackout

When the power goes out, a few simple actions can help keep you safe, calm, and in control:

Create an emergency kit with candles, first aid supplies, batteries, and chargers.
Unplug major appliances to protect them from power surges when electricity is restored.
Keep the fridge and freezer closed – a closed fridge can preserve food for up to 4 hours, while a full freezer can maintain its temperature for 24–48 hours.
Gather your household in one room to stay warm and keep each other informed.
Store water in your bathtub or buckets in case the supply is disrupted.
Avoid unnecessary travel, especially at night or in poorly lit areas.
Check in on friends and family, especially those living alone or with health conditions.
