The Canary Islands have been suffering total blackouts for years. Their salvation is a beast of engineering 1,145 meters under the sea

A month ago, the destabilization of an old generator at the El Palmar thermal power plant in La Gomera caused a dramatic “cascade effect” that left more than 15,000 people without electricity, and without mobile coverage. This incident showed the extreme fragility from living in an isolated electrical system. However, the solution to this historical vulnerability no longer looks to the sky, but to the depths of the Atlantic. To overcome the abrupt volcanic orography and the extreme pressures of the Canary Islands seabed, engineering has had to design an “umbilical cord” unprecedented in the world, marking a before and after in the history of the archipelago. The end of isolation. In an effort to protect supply, Red Eléctrica de España (REE) has officially inaugurated the underwater interconnection between La Gomera and Tenerife. As confirmed by the REE itselfthe magnitude of the project translates into historic figures: an investment of 145 million euros for the cable laying, to which are added another 32 million destined for the two link substations located in Chío (Tenerife) and El Palmar (La Gomera). It is not a capricious work. How they collect local mediathe Canary Islands have suffered nine major “energy zeros” (total blackouts) since 2009. Tenerife and La Gomera have been among the islands hardest hit, so this infrastructure was born as a vital antidote to darkness. More than light. The implementation of this system completely alters the energy paradigm. As indicated ANDldiario.esboth islands cease to be solitary island systems and become a single network. From now on, if the rubber plant fails, Tenerife will inject energy instantly to avoid a blackout, and vice versa. But the scope of the work transcends mere security. As explained in detail in the REE statementcable is the key to decarbonization. La Gomera will now be able to generate much more renewable energy – mainly wind – than its population consumes. This green surplus will not be lost, but will travel along the seabed to Tenerife, drastically reducing the burning of fossil fuels on both shores. The technical challenge: engineering to the limit. Connecting two volcanic islands separated by abyssal trenches is not an easy task. As emphasized The Daythe 36 kilometer length of the cable descends to 1,145 meters below sea level. This extreme depth makes it the deepest tripolar alternating current link on the entire planet, snatching the record that linked Crete and the Peloponnese since 2021. To withstand the weight and crushing pressure of the ocean at these levels, engineering had to reinvent itself. To do this, they had to discard the traditional use of steel and lead, opting instead for an ultralight synthetic material armor and an insulation based on ethylene and propylene rubber. Caring for the environment was also a priority. In order not to destroy coastal biodiversity or alter shallow volcanic beds, from The Confidential detail that it was used the “directed drilling” technique: an underground microtunnel that allows the cable to exit to the sea hundreds of meters from the beach. Likewise, the terrestrial substations use GIS (gas-insulated) technology to occupy the minimum possible space, and their buildings have been camouflaged imitating greenhouses and agricultural terraces to integrate into the landscape. Laying underwater bridges. The milestone of La Gomera and Tenerife is just the beginning. Future planning, as pointed out The Daycontemplates the colossal challenge of joining Fuerteventura with Gran Canaria, an even greater challenge given that the distance between the two exceeds 100 kilometers. Parallel to the electrical revolution, the Canary Islands are experiencing an unprecedented leap in their telecommunications. As these local media detailthere are more projects like BASE 6, promoted by the public company Canalink. This is a new 328 kilometer fiber optic cable with a budget of 19 million euros that will link Tenerife with El Hierro, landing through a drilling on Tamaduste beach. This data highway, with a capacity of 5 terabits per second, seeks to eradicate the digital divide on the most remote island, guaranteeing services such as telemedicine or online education. The invisible network. The Canary Islands not only look inward. As contextualized by OCTSI (Canary Telecommunications Observatory), the archipelago has been functioning for decades as a global strategic node, surrounded by historic fiber rings and international connections such as Telefónica’s PENCAN cables, currently in the process of renovation. However, this strategic position has its geopolitical edges. An extensive report from my colleague for Xataka focuses on network extension from Canalink to Africa. The Canary Islands are financing a cable to the Moroccan city of Tarfaya with European funds. The problem lies in the fact that Morocco intends to extend this infrastructure towards Western Sahara, a movement that clashes head-on with the rulings of the EU Court of Justice and that threatens to place Spain at the center of a complex diplomatic and legal conflict with the Polisario Front. Overcoming geographic isolation. At 1,145 meters under the scrutiny of the waves, where sunlight does not reach and the pressure is unbearable, the heartbeat that unites two islands now runs. The Canary Islands are managing to transform their greatest geographical weakness—fragmentation and isolation—into a true global showcase of technological innovation. Little by little, the old and noisy combustion engines give way to a future that will be inescapably green, and deeply interconnected.

The US electrical grid does not support so many data centers so they have had an idea: disconnect them to avoid blackouts

January 11, 2026 by usatoday24

One third of all data centers in the world They are in the US and that is putting a huge burden on the electrical grid. One of the consequences that consumers are noticing is the price increases on the invoice, But electricity operators already foresee another problem: blackouts. What is happening. They tell it in WSJ. The US power grid is beginning to become strained, with grid operators expecting blackouts during periods of high demand. The solution they propose to avoid this is to make data centers disconnect from the network and use their own energy reserves temporarily. The technology companies have not been amused and talk about “discriminatory measures.” Why is it important. In 2023, data centers already consumed 4% of all the country’s electricity and the forecasts are that by 2028 that percentage will increase to 12%. The electrical grid is not prepared to support so much demand and, although it is already expanding, the pace of construction of new data centers is faster. Network operators face a difficult dilemma: powering data centers while maintaining supply to consumers. ‘Kill switch’. PJM Interconnection It is the organization that oversees the energy market in the Midwest, where they have already suffered from the problem of price increases. The concern that blackouts will occur is on the table and PJM has proposed that technology companies create their own energy sources or accept that their supply will be cut off if the network becomes too saturated. They are not the only ones who have raised something like this. With demand expected to double by 2035, Texas passed a law last year that contemplates a ‘kill switch’ that allows large consumers, such as data centers, to be disconnected at times when the network is under “extreme stress.” What the technologies say. As we said, the companies that own these data centers have not been very happy with the proposal. The Data Center Coalitionof which companies such as Google, Microsoft and AWS are part, have stated that the proposal is discriminatory since data centers need a reliable and stable network. They also warn that depending on their own energy reserves could have a negative environmental impact, by forcing them to use solutions such as diesel generators. Waiting times. There is an intermediate scenario in which technology companies can obtain benefits if they accept these conditions. As the electrical infrastructure does not support so much demand, data centers have to wait several years to be connected to the network, normally between 3 and 5 years, although there have been cases up to 8 years. Southwest Power Pool, the grid operator in Texas, has offered data centers a deal: give them access to the grid sooner in exchange for agreeing to be disconnected during times of high demand. According to a recent study Funded by Google, data centers that have more flexible connections (i.e., those that build their own power sources and accept temporary disconnections) typically connect to the grid several years faster than those that do not. Bring your own energy. Despite the reluctance towards that off button, generating your own energy is the most realistic solution and the one towards which the industry seems to be moving. Google recently bought an electrical company in order to obtain its own energy. Others big tech Amazon, Microsoft, Oracle or xAI are also exploring create your own energy solutions such as natural gas and solar panels.

The blackouts of Spain and London are a good example

June 2, 2025 by usatoday24

A couple of months ago, a fire in a substation left without electricity To a part of London and temporarily paralyzed Heathrow airport. A month later, the Iberian Peninsula suffered a mass blackout. Two incidents separated by kilometers, but united by the same question: how fragile is the electricity grid? More than is thought. The energy expert, Simon Gallagher has addressed this topiccategorically discarding the theories of sabotage or systematic negligence relying on data provided by UK Power Networks (UKPN) and Scottish and Southern Electricity Networks (SSEN). According to Gallagher, the failures in transformers are not only common, but also expected in such a complex system. UKPN, for example, reported about 400 failures of transformers a year, although only about 30 affect more than 500 customers. Although these failures can affect from small transformers in rural posts to large urban units, the figure has remained stable. Is it stable? Simon Gallagher is based on The 2024 UKPN annual reportwhere the average customer was without electricity just 29 minutes throughout the year, which is equivalent to an availability of the service of 99,994%. This level of reliability is the result of years of investment and continuous improvement. Since 2010/11, UKPN has reduced its lost minutes by client by 55% and interruptions by 43%. A very controlled system. The British electrical system is designed with a high degree of resilience. When a component fails, there are alternative routes through which electricity can be redirected, avoiding interruptions. This capacity is complemented with automatic failure detection technologies, which isolate the breakdowns in seconds and, in many cases, restore the supply without human intervention, Thanks to self -refrarable networks or Self-Healing Grids. To this is added Predictive maintenancewhich allows to replace or repair components before they fail, and a hierarchy of equipment that minimizes the impact of the failures: a failure on a low -load transformer affects little, while high voltage those receive greater protection. This robust architecture It is backed by the Riio-Ed2 regulatory frameworkpromoted by Ofgem, which forces distributors to maintain strict standards of reliability and response. So the blackout of Spain? While the British electrical system relies on a hierarchical network with high redundancy, predictive maintenance and self -repair technologies, the recent blackout in the Iberian Peninsula has shown that the resilience of the Spanish system needs to evolve in another direction. The more you know about the incident, less weight has the initial explanation focused on the lack of inertia by renewables. On the other hand, the absence of distributed storage, The lack of micro -redes capable of temporarily isolation of the main system and low capacity of local response. The blackout, even in the absence of official information so far we know that it was not due to a generation failure but to A chain disconnectionaggravated by a centralized architecture that could not contain the domino effect. This has revived the debate about the need to modernize the network; In that sense, the British model not only stands out for its technical robustness, but also for its regulatory anticipation against high renewable penetration scenarios. How invisible it works. In a world where what fails attracts more attention, it is worth remembering how extraordinary that, despite hundreds of daily technical failures, electricity continues to reach our homes without interruption. As Simon Gallagher concluded: “Everything fails … and yet the lights remain on.” Image | Senate Agr Xataka | Saving the network after the blackout has had a side effect: more expensive light and marketers to the limit

A country has literally found the bomb -proof solution to the large electrical blackouts: Ukraine

April 29, 2025 by usatoday24

It happened a few hours ago. Among the multiple calls that the Spanish Government has received from countries, worrying about the emergency situation after The national blackoutone did not go unnoticed. Zelensky, president of Ukraine, called Pedro Sánchezand not only to show your support, but to provide all the necessary help. After all, if anyone knows about blackouts, that is the nation of the East. They have learned to survive in the dark and Russian bomb proof. The devastation of the electrical system. From the beginning of the large -scale invasion in February 2022, Russia has directed a good part of its attacks against infrastructure Ukrainian energy. Last summer, Ukraine had lost and in just three months More than nine gigawatts of generation capacity, more than a third of the one it owned before the war. According to Ukrenergo dataThis would be equivalent to the total demand of countries such as the Netherlands at peak hours, or even the sum of Slovakia, Latvia, Lithuania and Estonia. Winter. All state thermal plants were destroyed and all hydroelectric plants had suffered damage to missiles or drones. The strategy of Russian attacks was clear: it was not only sought to destroy military capacity, but to break the soul of a society through forced darkness, interrupting the most essential: Heating, running water, elevators, communications, operating rooms or the simple possibility of maintaining an organized civil life. Today, and according to the UN agency for refugees, More than 60% From the country’s electricity generation capacity it has been destroyed or useless. In a country where winter is not only a station but an existential threat, running without energy is running out of heating, without water, without communications. For millions, electricity represents the last bastion between dignity and precarious survival. Survive blackouts. He told the last July the BBC that the blackouts in Ukraine had become a presence as constant as the war itself. In cities such as Odessa, Kyiv or Zaporizhzhia, electricity was an intermittent luxury, a resource that appears and disappears under the buzzing of the generators or the sepulchral silence of the fallen network. In that context, electricity ceased to be just a comfort to become the threshold between life and death. Cases like Tetiana’smother of a child with serious disabilities, who lives that truth every day: her son depends on breathing machines, feeding and receiving medication. Without stable supply, his life hangs from a thread. In your home, prolonged blackouts (sometimes twelve hours a day) force to constantly feed a gasoline generator that, in addition, must stop every six hours so as not to overheat. When your child convulses, the minutes without mobile or ambulance coverage are transformed into torture. In words to the British environment“You can die if you don’t receive oxygen. I am missing words.” Thus thin is the line between chaos and survival. Scheduled cuts. In August of last year there was a substantial change in the struggle of Ukraine to the blackouts. A Mondayhundreds of missiles and Russian drones fell on the nation. First the electricity was cut, then the water. That day marked the Greater Russian air attack against Ukrainian energy infrastructure since the beginning of large -scale invasion. The bombing continued the next day, raising the number of deaths to twelve and leaving millions of people throughout the country. The largest private energy company in Ukraine, DTEKmade a decision: Apply scheduled cuts In multiple regions: Kyiv, Odesa, Dnipropetrovsk, Donetsk. On the periphery of the capital, the neighbors began to live with six hours of blackout followed by two hours with electricity, in the early morning. A rhythm that allowed planning (even if not resting). Loading with energy. The result of the situation is that Ukraine has learned to live with the blackouts. What would have paralyzed the country before, today faced with Decentralized solutions. In Kyiv, the so -called “invincibility points” offer citizens electrical charge and the Internet during the cuts. But many do not even go to them: they have made portable batteries an object as essential as mobile phone or keys. Most shops, from street stalls to shopping centers, already have their own generators. In fact and as we said, that buzz of its engines has become the usual soundtrack of the blackouts. Examples Told the CNN Maksym Holubchenko, a 25 -year -old barista in the capital, that his cafeteria remains open thanks to one of those generators. However, it does not supply to cover all the demand: in winter you can maintain the operation, but in summer they must turn off the air conditioning and parts of the coffee maker so as not to overload the system. Adaptation is not comfortable, it is simply the result of an urgent need, and a resistance without alternatives. For Inna, an 87 -year -old woman from Odessa, the current situation arouses ancient echoes. “I already survived World War, so I have some experience … I bought candles,” He reported. His story underlines a painful paradox: a modern, European country, with full integration ambitions in the West, forced to technologically retreat, to depend on the rudimentary to face the essential. The candles, thermos, the portable loaders, the calendars marked by electric cuts … make up a new normality born of the energy siege. Go to the bank without light. Before prolonged blackouts caused by Russian attacks on energy infrastructure, the National Bank of Ukraine has also launched the Power Banking Projecta network of autonomous bank branches designed to operate without depending on the electricity supply. These “unwavering” offices will be equipped with generators, special communication channels, ATMs, additional and effective personnel available, allowing citizens to access essential services such as money withdrawals, payments, transfers, currency change and financial advice even during prolonged cuts. In addition, a “National Roaming System” Between ATMs, with unified limits and without commissions between banks, initiative already adopted by entities Like Oschadbankto guarantee equitable cash access throughout the country. Broken as a resistance symbol. In short, Ukraine applies preventive cuts Not only … Read more
