US EditionSpain and Portugal 2025 Blackout Caused by 'Multiple Factors'
The April 2025 blackout on the Iberian Peninsula was caused by voltage control failures and multiple system issues, leaving parts of Spain and Portugal powerless for up to 16 hours.
- On Friday, the European network of electricity transmission system operators released a report on the April outage that left large parts of Spain and Portugal without power for up to 16 hours.
- A voltage surge triggered a chain of power-generation loss, as the Spanish grid operates with narrower voltage margins than other European systems and thermal power plants failed to regulate voltage as expected.
- Manual voltage control and mismatched equipment settings delayed response times, while management of power links with France exacerbated system behavior and plant owners lacked necessary data on initial losses.
- ENTSO-E recommends improving system monitoring and better coordination and data exchange among power system players to prevent similar incidents.
- The report aims to reinforce Europe's power grids using available solutions and is not intended to assign blame, emphasizing technical guidance for future stability.

A complex investigation into the causes of the disaster in the Iberic Peninsula since April last year has been completed without any definitive evidence: until now there has been a place as a result of the interaction at least 17 different factors and raises concerns about the inadequate government and infrastructure, according to Euroactive.
The final report reveals failure to control the level of tension in the Spanish electrical system, but acknowledges that before a phenomenon of these has caused a panic and says there are solutions to prevent it.
The panel of European experts who investigated the blackout in Spain and Portugal on 28 April does not point out guilty, as the CNMC in its final report, and determines that the electric zero was produced by "multiple factors that interacted with each other", coming from a "very local problem" in southern Spain that "scaled very quickly." As in its factual report of October, the European investigation avoids pointing out a single culprit for the…
