Energy networks get ready for Storm Dennis

14 February 2020


Storm Dennis is forecast to bring unsettled weather to the UK and Ireland over the coming days. Here’s how our energy networks are preparing and what customers can do.

Energy networks are preparing

  • The networks in the UK are very resilient and built to withstand strong winds and heavy rain. However, during a storm other objects such as trees and airborne debris can pose a risk to infrastructure.
  • Network companies have been monitoring the weather system closely and are making preparations such as arranging for extra emergency staff to be on standby and placing vehicles and resources in strategic locations to help if any repair work is needed.
  • Network companies invest millions of pounds to build a resilient electricity network capable of securing electricity supplies and sustaining the challenges faced by increased demand and adverse weather. Year-round tree trimming programmes help reduce the impact storm debris can have on the overhead line network.

Advice for customers

You can take some simple steps to prepare for a power cut such as

  • keeping a mobile phone fully charged, adding 105 to your contacts and bookmarking in your smartphone
  • keeping a torch handy in case you are without power during the night
  • having warm clothes and blankets accessible if you have a prolonged power cut

Network operators work with suppliers to maintain a Priority Services Register to help identify vulnerable customers who may need additional support during a power cut.

Stay safe

It is very important that if you come across a fallen power line you keep everyone well away from it and call 105 to report it. Calling 105 will connect callers to their local network operator. This is also who you should call if you have a power cut. The 105 website also provides direct links and details of how to contact network operators online and via social media to get information and updates about a power cut.
