At the end of April 2025, parts of Spain and Portugal were without power for several hours – caused by a fault in the European interconnected power grid. This incident demonstrated that power outages can occur suddenly even in well-developed regions – without any severe weather or disasters. A good reason to think about your own energy supply – not out of fear, but with foresight.
What is a blackout?
A blackout is more than just a brief power outage. It refers to a widespread, prolonged failure of the electricity supply – with far-reaching consequences for communication, infrastructure, food supply, and the daily lives of every individual.
Why can a blackout happen here too?
Temporary network overloads can also occur in Germany. Possible reasons include:
- Extreme weather (storms, heat, freezing rain)
- Cyberattacks or technical errors
- Limited network reserves in the European interconnected system
A complete and prolonged blackout is unlikely – but not impossible. Proactive, self-sufficient energy management is invaluable in such cases.
Why it's worth being prepared

What do I need to prepare?
Good blackout preparedness focuses on three key pillars:
-
Emergency power supply (lights, communication, refrigerator, heating, medicine)
- Energy storage (to power independent devices)
- Charging options (solar panels or other charging sources for extended outages)
