Storm Arwen Review: Final Report

Volume 715: debated on Thursday 9 June 2022

The Energy Emergencies Executive Committee Storm Arwen review was commissioned in December 2021 by the Secretary of State for Business, Energy and Industrial Strategy, due to unacceptable levels of power disruption following Storm Arwen. The interim report was published in February 2022, and the final report has now been completed and published on

The review has been a joint endeavour between Government, industry and the regulator (Ofgem) with the aim of identifying lessons to be learned and actions to take forward. These actions will drive improvements to Great Britain’s electricity network resilience to severe weather events. The actions recommended by this review address concerns under the three pillars of system resilience, consumer protection and additional support.

The majority address improvements to be made across all electricity distribution network operators regardless of their impact during this particular storm. Lessons from subsequent storms that hit the UK in February 2022 have also been incorporated and reflected as part of this final report. While improvements will be made, no electricity system can be totally immune from disruption.

The Energy Emergencies Executive Committee will be responsible for the implementation of these actions, in collaboration with other partners as appropriate, alongside my Department which will ensure the delivery and implementation of the actions recommended.
