Details
On Friday 9 August 2019 a power disruption resulted from the operation of Low Frequency Demand Disconnection relays on the Great Britain power system at about 4.54 pm. It impacted hundreds of thousands of customers, and caused significant secondary impacts in particular to the transport network. Though demand was fully restored within 90 minutes, the secondary impacts continued to be felt for much of the day.
The Secretary of State for Business, Energy & Industrial Strategy has commissioned the Energy Emergencies Executive Committee (E3C) to undertake a comprehensive review of the incident. The review should identify lessons and recommendations for the prevention and management of future power disruption events. In particular E3C will:
- assess direct and secondary impacts of the event across GB electricity networks
- Identify areas of good practice and where improvements are required for system resilience
- consider load shedding in regard to essential service customers and prioritisation
- consider timeliness and content of public communications during the incident
- make recommendations for essential service resilience to power disruptions
E3C will submit a final report to the Secretary of State within 12 weeks, with an interim report within 5 weeks. These will be published here. BEIS will provide the secretariat for the review.
E3C is a partnership between government, the regulator, and industry, which ensures a joined up approach to emergency response and recovery.
