Power has also begun to return in Barcelonès, Garraf, Alt Penedès, Baix Llobregat, Vallès Occidental, Vallès Oriental, and Maresme regions, after reports of restoration in Osona, Vallès Oriental, and several Girona regions such as Giron were received at 2:30 p.m. This afternoon, Red Eléctrica confirmed that the general outage in Spain and Portugal could take between six and ten hours to resolve.
Red Eléctrica has also said through its X account that it has been able to recover voltage in substations in various areas of the north, south and west of the peninsula.
Despite the gradual restoration of electricity, Civil Protection is urging the public to "use electricity in moderation and responsibly until normality is fully restored." Along these lines, the Minister of the Interior, Núria Parlon, also urged people to "refrain from using their cell phones unnecessarily." She also urged citizens to limit mobility "to what is strictly necessary while the power outage persists." In fact, many traffic lights are not working.
