Blackout Spain: How to prepare for a power outage

Is Germany, Europe, or the USA also facing a similar power outage?

Yesterday, Spain experienced a massive, nationwide power outage. All households and businesses were suddenly without electricity – and some regions are still affected today. This event impressively demonstrates how vulnerable modern infrastructures are.

But what does this mean for us in Germany, Europe, and the USA? How high is the risk of a blackout? And most importantly: How can you effectively prepare for a power outage?

What should you do in case of a sudden power outage?

When the power goes out, every minute counts. Here's a step-by-step guide:

1. Stay calm

Panic helps no one. Take a deep breath and collect yourself before taking further action.

2. Check the power source

• Is there a local problem (e.g., a tripped fuse)?
• Or is the entire block or street affected?

3. Gather information

• Use mobile network and mobile data (use sparingly).
• Turn on an emergency radio (battery-powered or crank radio).
• Check social media or apps of local authorities.

4. Protect devices

• Unplug electrical devices.
• Particularly sensitive devices like TVs or PCs should be protected from power surges. For this, there are UPSs, or uninterruptible power supplies, which can buffer for some time even during a power outage.

5. Conserve energy

• Only use mobile phones, flashlights, and other battery-powered devices selectively.
• Use power banks and solar chargers.

How can you prepare for a major power outage?

Good preparation makes all the difference in an emergency. Here are the most important points:

Emergency equipment for power outages:

✅ Flashlights (with spare batteries)

✅ Battery-powered or solar-powered radio

✅ Charged power banks and solar chargers

✅ Water supply (at least 2 liters per person per day for 3–5 days)

✅ Food supplies (canned goods, dried fruit, nuts, energy bars)

✅ First aid kit

✅ Cash in small denominations

✅ Gas stove or camping stove (with sufficient ventilation!)

✅ Thermal blankets, sleeping bags

✅ Candles and lighters (use with caution!)

Additionally important:

• Always keep your car tank half full. Gas stations might not work during a blackout.
• Emergency contact list on paper. Mobile phones might fail or run out of battery.
• A designated meeting point for family and friends.

Important: Even with a solar system, you are often without power during an outage❗️

Many people think: "I have a PV system – so I'm covered in case of a power outage."

However, in most cases, this is unfortunately incorrect.

Why?

Most photovoltaic (PV) systems are grid-tied. This means:

• If the public power supply fails, the system automatically shuts down.
• This is legally regulated to prevent power from being fed back into the grid (risk to technicians' lives).

What do you need to still have power?

✅ A battery storage system AND

✅ an emergency power function / backup power outlet / backup power capability

Only special systems (e.g., with a backup box, emergency power switchover, or backup power function) can continue to supply power during an outage – and even then, often only for specific consumers (like lights, router, or refrigerator).

Tip: Check your solar system to see if a so-called "backup power circuit" is available – or if it can be retrofitted. ❓

Could a blackout also hit Germany, Europe, or the USA?

The short answer:

Yes – the danger exists, though to varying degrees.

In Germany:

• Very stable power grid due to decentralized supply.
• Increasing strain due to the energy transition, electricity exports, and fewer base-load power plants (e.g., nuclear phase-out).
• Critical loads are possible on extremely hot or cold days.

Expert opinion: The probability of a nationwide blackout is low, but not zero. Local or regional power outages are more likely.

In other European countries:

• France: Heavily reliant on nuclear power; technical problems can lead to bottlenecks.
• Italy/Spain/Portugal: Higher susceptibility due to heat, overload, and outdated grid infrastructure.

In the USA:

• Significantly higher blackout risk than in Europe.
• Extreme weather events like hurricanes, cold snaps, or overheating regularly strain the grids.
• Examples: Texas blackout 2021, Californian power outages during heatwaves.

Why did the power outage occur in Spain?

Although the official cause is still under investigation, initial reports point to the following combination:

• Sharply rising electricity consumption, especially due to air conditioning.
• A high proportion of photovoltaic systems, which causes strong feed-in at midday – but can also make the grid unstable if insufficient storage or flexible consumers are available.
• Lack of grid buffering and load control, which can culminate in widespread power outages.

Spain has invested heavily in solar energy in recent years – which is ecologically sound but makes the grid more susceptible to fluctuations if sufficient storage and control technology do not grow with it. And: Such chain reactions can develop anywhere where demand and supply suddenly no longer match.

Conclusion: Preparedness is the best protection

A massive power outage can become a reality faster than we think. Those who are prepared protect themselves and their families from unnecessary stress and potential dangers.

Act now before it's too late:

• Stock up on supplies
• Upgrade equipment
• Create emergency plans

Because as the saying goes:

“Crises rarely come with a warning.”
