Publication of final technical report - September 9

A National Grid Electricity System Operator spokesperson said: “We have been working hard, in parallel with colleagues across the industry to understand the causes of the 9 August power cuts and why it caused disruption to services across Great Britain.

“We have now published the final technical report submitted to our regulator Ofgem, which confirms the rare circumstances that led to the power cut and how the electricity system operated as it should and within the operational guidelines by which we are governed.  

“We welcome Ofgem’s response and the opportunity to submit further reports to the Energy Emergencies Executive Committee enquiry, making sure any lessons learned and changes made are in the best interests of the consumer.”
