Grid operators in Spain and Portugal said that power supplies are back to normal, a day after a crippling blackout hit the Iberian peninsula.
Portugal
On Tuesday, the government said all 6.4 million electricity clients had power supplies normalised after the country-wide blackout. It said in a statement all airports were operating, if with some recovery still underway in Lisbon, and trains were working. Schools were also reopening and the health service fully stabilised.
The widespread blackout affected Spain, Portugal and parts of France, halting trains, grounding flights, disrupting mobile networks, and leaving millions without power, as authorities rushed to restore services.
Portugal’s grid operator REN told AFP “all the sub-stations of the national transport network have been re-established” and “we can now affirm that the network has been perfectly stabilised.”
Spain
In Spain, the electricity grid operator Red Electrica said it was able to supply virtually all of the country’s electricity demand early on Tuesday as the system gradually recovers from a nationwide blackout on Monday, although most trains were still not running.
All of Spain's substations were operating on Tuesday morning, Red Electrica said in a post on X social media. “We keep on working from centre of electric control to secure total normalization of the system,” it added.
Electricity goes out across Portugal, Spain, and Andorra – a microstate between Spain and France – around midday on Monday, also affecting parts of France.
The Madrid underground metro network said it had resumed operating at 8 am (0600 GMT) with 80 percent of trains circulating, but railway infrastructure operator Adif said most trains nationwide were not operating.
A huge power outage hit most of the Iberian Peninsula on Monday morning, bringing both Spain and Portugal to a standstill - grounding planes, halting public transport and forcing hospitals to restrict routine proceedings.
Power supply was gradually restored in both countries from late Monday afternoon and early evening though some operations were still not able to resume on Tuesday morning.
The cause of Monday’s power outage was unclear.
Prime Minister Pedro Sanchez said that the country had suffered a loss of 15GW of electricity generation in five seconds, equivalent to 60 percent of national demand. The loss triggered a disconnection of the Spanish and French grids, prompting a general collapse of the Spanish system, Red Electrica;s chief of operations Eduardo Prieto told reporters on Monday evening.
Some areas in France suffered brief outages on Monday. Portugal’s grid officials suggested the issue originated in Spain.
Spain is one of Europe’s biggest users of renewable energy sources, but Monday’s shutdown has already sparked debate about whether the volatility of supply from solar or wind has made its power systems more vulnerable to such an outage.
The reasons for the loss of power are unknown, Sanchez said, adding no hypotheses are ruled out, he added. Portuguese Prime Minister Luis Montenegro said there was “no indication” a cyberattack was behind the outage.
