Spain's Energy Sector Under Scrutiny: Uncovering the Causes of the 2025 Blackout

Spain's energy regulator is investigating major energy firms and the grid operator over the 2025 blackout in Spain and Portugal. While the blackout's immediate cause was a voltage surge, some rules may have been breached, leading to an extended probe into power operations.

Spain's energy and competition watchdog has launched formal investigations into the country's largest energy firms and the power grid operator concerning last year's unprecedented blackouts in Spain and Portugal.

This decision follows evidence suggesting that some power sector regulations were breached for extended periods, which may have impacted power system operations.

Reports indicate these violations were not directly responsible for the blackout's occurrence, but they necessitate in-depth analysis to address potential administrative infringements. Investigations are expected to last between nine and 18 months.
