Power outages are normally caused by minor factors in your home or in your local area.


The Norwegian Water Resources and Energy Directorate (NVE) has information on its website to assist consumers with answers to a number of questions.


If you experience a power outage at home, you should first check this:

Check whether the earth-fault circuit breaker has been triggered, if applicable


Check whether the circuit breaker has tripped. If so, disconnect all connected equipment. Then try to reconnect one item of equipment at a time, to see if the circuit breaker is tripped again. If you find the cause of the circuit breaker tripping or fuse blow out using this method, then the equipment is faulty and must either be repaired by an expert, or discarded.


If the fault is in the permanent installation, you must contact an electrician. The Directorate for Civil Protection and Emergency Planning (DSB) has a registry where all approved enterprises should be listed. You can see who is registered and find the nearest enterprise to you on this website.


If both the earth fault circuit breaker and fuses are intact, you should check to see if your neighbours have also lost power. If so, you must contact the power grid company.

Extreme weather and extended power outages

Sometimes, power outages can be caused by major events such as extreme weather. Between Christmas and New Year’s 2011, Western Norway experienced the extreme weather system Dagmar, and the strongest hurricane in 20 years. Dagmar caused significant damage, including a large number of downed trees on power lines which caused power outages for large segments of the population in the affected areas.


In extreme situations, it may be difficult for individuals to contact their power grid company to obtain information about when power is expected to be restored. In such cases, the municipality will try to have the most up-to-date information available, as well as a current picture of how the grid companies are handling the situation – and when they expect power to be restored.


Loss of power also causes disruption of telephone service because the mobile system depends on power supply. During the Dagmar extreme weather, many people were without telephone service. In such cases, the authorities and others who can provide information will use the radio to reach the public. It is important to listen to the information on the radio, preferably NRK P1 or the local radio.


Norway regularly experiences extreme weather events like Dagmar. In such situations, it may be difficult to determine when power will be restored. It is important for individuals to prepare for handling such situations in the best way possible. The forecasting of extreme weather events is always broadcast on TV, radio and on the website yr.no. For example, you may want to consider alternative heating methods, check whether you have sufficient alternative sources of light, the ability to prepare food, and whether you have the medicines you need.
