The Expert Panel composed of ENTSO-E and the relevant Transmission System Operators (TSOs) as well as ACER and relevant National Regulatory Authority (NRA) representatives publish their Final Report on an incident which separated on 24 July 2021 for about an hour the Iberian Peninsula from the rest of the Continental Europe power system.
In view of the customer disconnections, the incident was ranked level two according to the ICS Methodology and an expert panel was set up on 22 October 2021 to carry out an investigation.
Today, after several months of intensive and close collaboration of all parties involved, the expert panel issues its final report. It provides a comprehensive analytical overview of the incident – the causes and the consequences - and proposes recommendations to prevent and mitigate the consequences of similar events in the future.
The Expert Panel’s analysis concludes that this incident was atypical in that it resulted from the failure of an efficient and suitable communication channel between the emergency services and the TSO. It did not originate from any faults in system operation or planning. The system defence plans functioned properly and coordinated measures were activated quickly.
