Spain & Portugal power outage LATEST: Electricity returns but cause of mass blackout still a mystery

THE lights are on and the bars are open as Spain and Portugal celebrate the return of electricity following a mass blackout.

Electricity had been restored to nearly 90% of mainland  by early on Tuesday, the grid operator REE said.

Power was restored overnight to around 6.2m households in Portugal out of 6.5m, according to the national electricity grid operator.

Lights also came on again in Madrid and in Portugal’s capital, Lisbon, last night to massive cheers.

  • Lights return in Madrid after massive power outage

    Lights came back on across Madrid late Monday as Spain's power operator said it was progressively overcoming a massive power outage that plunged the Iberian peninsula into darkness.

    More than 35 percent of Spain's power demand was being met, the country's REE electricity operator.

    Portugal's operator said it had also made gains in overcoming the outage.

    "By 8:35 pm (1835 GMT) REE was meeting "35.1 percent of demand", Eduardo Prieto," REE's operations director, told Cadena Ser radio.

    In Madrid, traffic lights and the storefronts of shops slowly became lit up in different districts.

    REE said earlier that power was being "progressively" restored across the country.

    Meanwhile Portugal's REN power operator was aiming for full restoration by Tuesday.

    "I hope we will manage to balance the whole system during the night," REN administrator Joao Faria Conceicao told journalists.

    Already some 750,000 customers, out of some 6.5 million, were back online Monday evening including the whole of the city of Porto.

    REN reiterated there was still no firm cause for the shock mass outage.

    Portugal's electricity provider REN said Monday evening it had restored power to some 750,000 consumers following a widespread blackout that left the nation and neighbouring Spain in the dark.

    Portuguese grid operator REN said on Monday it had "no information" that the mass power outages that hit the Iberian Peninsula were caused by a cyberattack.

    "If it were up to REN, the country would wake up tomorrow with electricity, but unfortunately it's not just REN that counts," he added.

    “I was able to pay in cash, but at this point in a holiday I have just a little bit that I was looking to get rid of at the airport. If this went on for days it would be hell.

    “I’ve got a higher car and will be driving to the airport later, but I’m nearly empty on fuel and I’ve not been able to fill up anywhere.

    “It just goes to show you, everything can go from being fine, to be in potentially dangerous, completely out of the blue.”

    The dad, of Southampton, Hants, added: “We are too reliant on technology. I’ve always told my kids this, and now I can see.

    “I just hope nobody was hurt during this. It’s mayhem.”
