Attention turns to renewable energy after Spain-Portugal blackout
Sanchez says Spain will not allow blackout again and vows accountability for private companies
While the cause of a widespread power outage that plunged Spain and Portugal into blackout is still under investigation, a "generation disconnection" within the Spanish power grid is suspected.
Although Spain relies heavily on renewable energy, officials have ruled out renewables as the direct cause of the blackout.
Experts suggest a technical issue with a high-voltage cable connecting the French and Spanish grids may have contributed.
The incident highlights the need for stronger and more resilient power grids to accommodate the increasing use of renewable energy sources, they say.
The outage has caused significant disruption across the two countries, with about 500 flights cancelled and tens of thousands of travellers stranded.
