MADRID: Power had almost fully returned to Spain early Tuesday morning as many questions remained about what caused one of Europe’s most severe blackouts that grounded flights, paralyzed metro systems, disrupted mobile communications and shut down ATMs across Spain and Portugal.

By 7:00 a.m. local time, more than 99 percent of energy demand in Spain had been restored, the country’s electricity operator Red Electrica said. Portuguese grid operator REN said Tuesday morning all of the 89 power substations were back online since late last night after an “absolutely unusual” blackout and power was restored to all 6.4 million customers.

On Tuesday morning, as life slowly returned to normal on the Iberian Peninsula, outside Atocha station, one of the busiest in the Spanish capital, people were once again crossing the street while looking at their cell phones, despite the Internet connection being intermittent at times.

Inside, hundreds of people waited to board trains or rebook those that had been canceled the previous day. Large groups of people milled around the screens, waiting for updates. Still, several people slept on the floor with blankets provided by the Red Cross for those who waited overnight at the station. The same scenes were replicated at Sants station in Barcelona. Classes were suspended in several regions.

The Madrid Open, the tennis tournament being held this week, was still affected by the power outage after its cancelation the previous day and delayed the opening of its doors.

Power had gradually returned to several regions across Spain and Portugal as the nations reeled from the still-unexplained widespread blackout that had turned airports and train stations into campgrounds for stranded travelers.

Monday night, many city residents, including in Spain’s capital of Madrid, went to sleep in total darkness. The normally illuminated cathedral spires of Barcelona’s Sagrada Familia Basilica became indistinguishable from the night sky. Streets remained deserted even in neighborhoods where lights flickered back on, as people stayed home after a day of chaos.

“We have a long night ahead,” Spanish Prime Minister Pedro Sanchez said when he addressed the European nation late Monday. “We are working with the goal of having power restored to the entire country.”

In Madrid, cheers erupted from balconies where the electricity had returned.

Subway service returning on Tuesday morning

On Tuesday morning, Madrid’s metro system was restored on all but one line, meaning that 80 percent of trains operated during rush hour.

In Barcelona, the metro was also operating normally, but commuter trains were suspended due to “electrical instability,” the company that runs the service, Rodalies Catalunya, said on X. In other parts of the country, commuter and mid-distance services were also suspended or running at reduced capacity.

As metro service stopped on Monday, train stations cleared out and shops and offices closed, and thousands of people spilled onto the streets of Madrid.

Emergency workers in Spain said they rescued some 35,000 passengers stranded along railways and underground.

The blackout turned sports centers, train stations and airports into makeshift refuges late Monday.

“We were in the north of Portugal and did get any notifications until we got here because of Internet outage,” said Ian Cannons, a British tourist trying to get home who was forced to spend the night in Lisbon’s airport. “We can’t book any hotels. Nothing.”

The Barcelona municipality distributed 1,200 cots to indoor recreation centers to host residents with no way to get home and international travelers left in limbo. All over Barcelona and Madrid, people were sleeping on train station benches and floors.

Cash and radios in high demand

As Internet and mobile phone services blinkered offline across Spain and Portugal, battery-powered radios flew off the shelves. Those fortunate enough to find service shared whatever news updates they could with strangers on the street.

Lines snaked out of the few supermarkets running on backup generators in Barcelona and Lisbon as people stocked up on dried goods, water and battery-powered flashlights and candles. Clerks counted euros by hand, since many cash registers had stopped working.

Hector Emperador, picking his kids up from school in Barcelona, said he resorted to raiding his sons’ piggybank to ensure he had cash on hand after ATMs and some online-banking services shut down. “The coronavirus pandemic will be nothing compared to this,” he said.

Few gas stations were operating, sending the drivers who dared navigate without traffic lights scrambling for fuel. Residents with electric door keys found themselves locked out of their homes.

The many inconveniences became a threat to survival for those with medical needs like refrigeration for insulin or power for dialysis machines and oxygen concentrators. Some hospitals – but not all – stayed open with the help of generators.

Cause remains a mystery

Officials did not say what caused the blackout, the second such serious European power outage in as many months after a fire at Heathrow Airport shut down Britain’s busiest travel hub on March 20.

They said there was little precedent for this kind of widespread electric failure across all of the Iberian Peninsula, with a combined population of some 60 million. Across the Mediterranean Sea, Spain’s Balearic Islands and the territories of Ceuta and Melilla were spared. The Canary Islands off the northwest coast of Africa were also spared.

“We have never had a complete collapse of the system,” Sanchez said, explaining how Spain’s power grid lost 15 gigawatts, the equivalent of 60 percent of its national demand, in just five seconds.

In his televised address late Monday, Sanchez said that authorities were still investigating what happened. Portugal’s National Cybersecurity Center threw cold water on feverish speculation about foul play, saying there was no sign that the outage resulted from a cyberattack.

Speaking to reporters in Brussels, Teresa Ribera, an executive vice president of the European Commission, also ruled out sabotage. Nonetheless, the outage “is one of the most serious episodes recorded in Europe in recent times,” she said.

BEIJING: China on Tuesday blamed US tariffs for Beijing’s decision to stop accepting new aircraft from aviation giant Boeing, saying the levies had “disrupted the international air transport market.”
“The United States’ wielding of tariffs has severely impacted the stability of the global industrial chain and supply chain,” China’s commerce ministry said in a statement.
“Relevant Chinese airlines and Boeing in the United States have suffered greatly,” a spokesperson said.
New US tariffs have reached 145 percent on many Chinese products, while Beijing has responded with fresh 125 percent duties on imports from the United States.
And Boeing’s CEO confirmed last week that China had stopped accepting new aircraft due to the trade war.
In a televised interview with CNBC, Boeing chief executive Kelly Ortberg said Chinese customers had “stopped taking delivery of aircraft due to the tariff environment,” adding that if the halt continued, the aviation giant would soon market the jets to other carriers.
Boeing had planned to deliver around 50 aircraft to China in 2025, said Ortberg, adding that the company wouldn’t “wait too long” to send the jets to other customers.
US President Donald Trump also criticized Beijing for backing out of the deal, saying Boeing should “default China for not taking the beautifully finished planes.”
Beijing’s commerce ministry on Tuesday hit back, saying “many companies have been unable to carry out normal trade and investment activities” due to Trump’s tariffs.
“China is willing to continue to support the normal business cooperation between the two countries’ enterprises,” its spokesperson said.
Beijing “hopes that the United States can listen to the voices of enterprises and create a stable and predictable environment for their normal trade and investment activities,” they added.
