On Monday, April 28, large parts of the electricity systems in both Spain and Portugal went down shortly after noon. Now an international expert group will try to find out what triggered the major blackout. Energinet writes this in a post on LinkedIn.
The expert group has been set up by the European Union of Electricity Transmission Companies, ENTSO-E, in cooperation with the regulatory organization ACER. The task is to prepare an independent report that both identifies the cause and makes suggestions for how similar incidents can be prevented.
Bent Myllerup Jensen, who heads Energinet's control room, will participate from the Danish side. He is contributing to the work of reviewing the many thousands of data lines that both Iberian and other European power systems have registered in the minutes surrounding the breakdown.
"The work may not be finding a needle in a haystack, but may well turn out to be finding the cause in one of the thousands and thousands of data that not only the power systems in Spain and Portugal registered when the power systems on the Iberian Peninsula went down, but also the many, many data that other TSOs collected," the post reads.
Energinet highlights in the post that Denmark has experience with power systems with a high share of renewable energy, which is relevant in the analysis of incidents like this.
