Portugal wants European regulators to lead Iberia's outage investigation

Portugal's acting energy minister said that it wants the European energy regulators, ACER, to conduct an independent investigation to determine the cause of the massive power outage which brought Spain and Portugal almost to a standstill in the last month.

Maria da Graca Carvalho stated that Prime Minister Luis Montenegro wanted an independent investigation conducted by the European Agency for the Cooperation of Energy Regulators in order to supplement the technical report prepared by the European Network of Transmission System Operators ENTSO-E.

Carvalho, in response to questions, said that "ACER is a suitable entity for coordinating any external evaluation process. It could bring more transparency, impartiality, and confidence to the conclusions."

In a written statement, the minister said that "there is no evidence at this time" to suggest that cyber attacks, human error or sabotage could have been the cause of the outage.

Last week, Spain's Energy Minister said that a sudden loss of electricity generation at a Granada site, followed by outages in Badajoz, Seville and seconds later, caused the unprecedented blackout in Spain and Portugal.

Iberia is behind the EU target of all countries having 15% of their energy systems interconnected with the wider European network by 2030. Iberia's contribution remains at only 3%.

Carvalho stated that Portugal, despite the reasons for the blackout, was considering how to improve the resilience and security in the national electric system. This is a strategic imperative. (Reporting and editing by Andrei Khalip, Jan Harvey, and Sergio Goncalves)
