Spain’s grid operator, Red Electrica de España (REE), has clarified that the recent blackout experienced across the country is not attributable to its growing reliance on renewable energy sources. This statement comes as Prime Minister Pedro Sanchez faces mounting scrutiny over the incident, which has been characterized as the most significant power outage in Spain’s history.
On Wednesday, REE indicated that the outage stemmed from two separate instances of reduced generation at substations located in southwestern Spain. However, officials are cautious about drawing definitive conclusions, as the precise reasons for these losses remain under investigation. Beatriz Corredor, REE’s director and a former Socialist minister, emphasized that suggesting solar power was to blame is misguided. She assured that the technologies backing Spain’s renewable energy infrastructure are robust and equipped to function alongside traditional energy generation systems without compromising safety.
In the wake of the blackout, which significantly disrupted daily life, normalcy is gradually returning across the Iberian Peninsula. The outage interrupted train services, grounded flights, and left individuals stranded in elevators in both Spain and Portugal. According to REE’s data, solar energy constituted 53 percent of electricity generation just prior to the outage, supplemented by wind energy accounting for nearly 11 percent, along with nuclear and gas contributing around 15 percent.
Political opponents of Sanchez have criticized his administration for the perceived delay in providing a comprehensive explanation regarding the blackout, accusing the government of potentially obscuring operational shortcomings in the wake of its substantial investments in the renewable energy sector. Opposition spokesperson Miguel Tellado of the conservative People’s Party has called for a parliamentary investigation, advocating for impartial scrutiny of the incident instead of the government-led inquiry Sanchez has proposed.
While Sanchez has not dismissed the possibility of a cyberattack, REE has verifiably ruled that scenario out. Further insights from energy expert Antonio Turiel, affiliated with the state-owned Spanish National Research Council, highlighted the systemic vulnerability associated with the grid’s instability. Turiel noted that the swift integration of numerous renewable energy sources lacked the requisite stabilizing systems, which may have contributed to the operational issues observed during the outage.
To address these challenges and accommodate the increasing demand from data centers and electric vehicles, the Spanish government is anticipating a public and private investment of approximately €52 billion (around billion) by 2030 aimed at modernizing the power grid.
