Thus, electricity regained the engineers after blackout in Spain and Portugal

Tuesday The state of emergency increased Throughout Spain and Portugal, Except in Extreadura and Madrid, which remains at the 3rd level. Andalusia, Castilla La Mancha, the Valnessian community, Galicia, Morsia and Riga returned to level 2.

Meanwhile, the Iberian Peninsula begins to restore electricity supplies yet Unprecedented Monday. The cutting of electricity affected Spain, Portugal and part of France Immediately after the two, according to the European network data for the ENTSO-E.

Dan Jorgensen, Energy and Housing Committee of the European Union “The most serious for about two decades in Europe”.

Researchers They continue to try to discover the cause From the collective blackout, experts claim that the network will start again after blackout and a good balance or another provocation must be achieved.

Suddenly the warnings are released

According to Red Electrica, communications It is the “spine” of the country’s electrical system. Connect power plants to adult consumers, distribution points and the rest of the National Energy Production It is necessary to transfer the energy resulting from electricity generation plants From one place to another in a “effective and safe” way.

The Spanish transport network contains more than 45,000 km of high voltage line circles, more than 700 subcontinents, 600 bays and more than 200 transformers. the Red from PortugalDespite the smallest, it has 9661 km of circles, and about 77 % of its energy that was produced on Tuesday It came from renewable energy As solar energy and wind, according to NACIONAIS ENERGY Networks Nacionais Energy Networks (REN).

Explanation of Paul Kofi, Deputy Professor of Electrical and Electronic Engineering at Dublin University (UCD), that Electrical networks are usually sync Or interconnected, which means that “if something negative with the Mawlid of Madrid, this will be observed immediately in Barcelona or Lisbon,” said “the next Euronews.”

The operators of the regime who control the electricity network are trying to keep balanceBetween the amount of energy provided by the network and the energy consumed. To reach this balance, operators remain around 50 pregnant women. The scale can rise or reduce slightly without a threat of blackout.

Perhaps the Iberian network failed quickly and unexpectedly. “Suddenly there is A wave of warnings(System operator) went ahead and looked at the screen, which, over the past five years, there has been no indication of problems … and (thought) What was the hell? “Cupfe says.

Recovery from blackout, a fragile balance

After blackout, The challenge of launching the network begins again. A spokesman for Eurelectric, the sector of the sector that represents the European energy industry, explained that the network should do the so -called “black start”, as “generations of obstetrics that do not need the electricity of the network to start” use to start electricity again.

In the event that the Iberi is overwhelmed, the association’s spokesman continued, this happened in the form Electrical energyBut it can also be done with diesel or gas. Electricity is injected from these alternative sources in the network and is used to restore basic services, such as hospitals or defense centers.

From there, the energy “is increasing slowly” and “carefully balanced with the additional demand made in the system”, the Eurelectric continues. “If the balance is not almost perfect, this may cause another blackout.”He adds.

The role of renewable energy sources

In 2024, Red Eléctrica announced that 56 % of The energy came from Spain from renewable energy. The network operator also confirmed on April 16 this year that it reached 100 % of renewable power supplies. On Tuesday, REN data showed that at 18:00 CET, 77 % of the energy resulting from Portugal came from renewable energy.

The introduction to the renewable energy network such as solar energy and wind, as well as new consumption patterns and adult consumers, makes the network system “more complicated” to balance, according to REN.

Entso -e warn at the beginning of the month Excess solar energy can occur When good weather begins to come. To alleviate this, the European Network for Electricity Transmission Managers said that transport systems operators will create specialized equipment for them Electricity DepartmentThrough greater flexibility with resources and exchange of information through the limits.

The next “Euronews” was contacted Red eléctrica yrn from Spain Asked about the preparations they took in response to Entso-E, but they did not receive an immediate response.

CUPFE stipulates this, though Renewable energy resource paper “relevant”It warns that electrical networks have long failed to include these new types of energy. “It will be a mistake to rush. But (also) it will be a mistake to adopt an excessive defensive position by how they dare stain renewable energies,” he said. “This network had a very high penetration, and it might be relevant,” Kofi said.

What will happen later?

Eurelectric said, that, Electricity also returnsYou will have to perform a safety examination to ensure that nothing happens along the electric line of the network or may cause a new blackout.

He asked “EURONEWS Next” also Red Electrica and Ren whether these security checks were made, but they did not receive an immediate response. According to EURECTRIC, The network will end with a return to regular energy ratesAnd late time will depend on the severity and size of a blackout.

There are still other investigations to do. he Spanish Prime Minister, Pedro SanchezAnd his Portuguese counterpart, Louis Montenegroand They have asked the European Commission an independent report About the reason for the blackout.

The official of the “Euronews” committee was not compatible with them to implement the investigation. It will be directed by transport networks (GRT) to a member state It is not related to the accident and will have members from Spain, Portugal and France in a committee to contribute to their experience. The committee will have up to six months To submit a research report on blackout that explains the causes of the accident and a series of recommendations.

Louis Calma, the Spanish National Court judge, said, It will open a preliminary investigation On whether it is a blackout It can be an electronic attackDespite many determinants from various government officials that it is not.
