Planning and preparing for power shortages

If electricity production and imports in Finland are insufficient to cover consumption in the winter, the distribution of electricity may need to be restricted, which could result in two-hour regional power cuts.

Effects of regional power cuts on Elisa’s services

Elisa is prepared for disturbances: critical items have been secured, and in case of a power outage, we would optimise our network capacity. However, a longer regional power cut would still have some effects on Elisa’s networks and services.

During such a power outage, voice calls and text messages would go through as normal. However, data traffic may experience slowdowns or unavailability during a power cut. Customer service contact points could also become busier than normal.

How to prepare for a power outage

  • Follow bulletins from the authorities and electricity suppliers.
  • Prepare in advance by keeping your devices and power banks charged up.
  • Avoid unnecessary use of your phone during the power cut, including voice calls and text messages.
  • Note that during a power outage, data connections could be very slow and congested, or be completely unavailable.
  • Plan your critical online activities (e.g. banking) around times when power cuts are unlikely.
  • If you receive advance notice of a power cut, disconnect sensitive electronic devices from the network before the power cut begins.
  • Remember that any power cuts will be localised and last a maximum of two hours. After this, services will return to normal functionality.
