Power outage in Cologne: RheinNetz fights against disruptions in Porz!

Today, July 4, 2025, Cologne citizens must expect power outages in some parts of the city. A fault report from RheinNetz GmbH informs that there is a need for action by technicians at two locations. The last update on the current disruption was at 7:45 a.m. These outages are localized and the average duration of disruptions in Cologne is far below the German average of a few minutes per year.

What you should know: A power outage usually does not constitute an emergency. Emergency numbers such as those for the police or fire department should only be called in serious cases. Instead, it is advisable to check the fuse box first. If only one fuse is actually tripped, you can easily turn it back on yourself. However, if problems persist, we recommend contacting a specialist.

How do I react to a power outage?

In the event of a failure that extends beyond your own household, the energy supplier should be informed. RheinNetz GmbH lists a clear procedure for this. First you have to check whether only your own home is affected. Neighbors or street lighting can be helpful indicators. If several households are affected, you can contact the energy supplier. For Cologne and the surrounding area, the telephone number is 0221 34645-600.

If the power outage only affects your home, the next step is to check the fuse box. Blown fuses may indicate a defect in a device. Checking the FI circuit breaker is also advisable, as this will interrupt the flow of electricity in the event of an emergency. If this has been activated, possible sources of error can be located by checking the circuit breakers step by step.

Power supply in Germany

Cologne is considered to be part of a stable power grid in Germany, which is generally perceived as resistant to disruptions. However, low-voltage disturbances in particular can occur. The Federal Network Agency emphasizes that the transmission network needs to be expanded in order to avoid network bottlenecks. These occur particularly in times of high wind and high loads, when a lot of electricity is generated in the north and a lot of it is needed in the south. In such moments, redispatching, the adjustment of the feed-in power from electricity generators, may also be necessary to ensure grid stability.

Overall, it is important to prepare for a power outage with the right information and procedures. In this way, inconveniences can be reduced to a minimum. RheinNetz GmbH also offers a free repair service if the cause of the failure lies in the house connection box. However, if there are defects in the house system, an electrician should be contacted.

For further information and help in the event of disruptions, the RheinNetz website is available: Report a fault. The Federal Network Agency also provides information about general security of supply and the measures to stabilize the electricity network: Security of supply.

So stay informed and react appropriately if the lights in your area go out!
