Lisbon, May 27, 2025 (Lusa) - The final report on the blackout that left the Iberian Peninsula without electricity on 28 April could be delivered within six months, the minister for the environment and energy announced on Tuesday.

On the sidelines of the Second Energy Conference of the Community of Portuguese Language Countries (CPLP), Maria da Graça Carvalho said that the European network coordinating electricity transmission operators (ENTSO-E) has committed to making "every effort" to bring forward the conclusions of the investigation.

Although the regulatory deadline for the final report is summer 2026, the Portuguese and Spanish governments have alerted the entity to the need to speed up the process.

"There is openness and goodwill on the part of ENTSO-E to speed things up, because it is under pressure not only from Portugal and Spain, but from Europe, which wants to know what happened and what to do to prevent it from happening again," said Maria da Graça Carvalho.

Although no firm date has been set, ENTSO-E has committed to making "every effort" to try to have the final report ready in six months.

According to the rules in force, the first factual report must be delivered by 28 October and will serve as the basis for the final report, which must be delivered by 30 September 2026 at the latest. A committee of experts is conducting the investigation set up specifically to analyse the incident, which has been classified as "exceptional and serious".

The blackout, which affected Portugal and Spain for over 10 hours, raised serious concerns about the safety and resilience of the European electricity grid.
