grid

Every time a megaship arrives at a port, the electrical grid collapses. The alternative already exists and does not need cables to the city

by

Ports around the world face an urgent and unavoidable mandate: decarbonize. The requirement is to turn off the huge diesel engines of commercial and cruise ships once they dock, connecting them to the local electrical grid. However, in practice, port cities have hit a concrete wall: there is not enough capacity in the land network to plug in these giants of the sea. Faced with this bottleneck, the engineering response has been to take the problem off the ground. A consortium backed by the United Kingdom and led by the firm ELIRE Maritime has been successfully validated what they define as “the world’s first floating, grid-independent hydrogen energy center.” The end of endless port works? To understand the impact of this development, you have to look at the current logistical ordeal. As emphasized Enlitinstall traditional shore power supply systems (known in the industry as shore power) is a real nightmare. The process can take between three and seven years, as it requires massive reinforcements of the network, improvements in substations, complex civil works and permitting deadlines that paralyze any progress. All this consuming land space that most ports lack. By placing the energy infrastructure directly in the water, this obstacle is overcome in one fell swoop. Furthermore, since ELIRE Maritime highlight a crucial financial advantage– The system avoids the risk of creating “stranded assets”. Unlike a concrete substation that cannot be moved if shipping routes change, this floating mega plant can be relocated as market demand dictates, giving port authorities complete independence from the network. Technological radiography. Far from being a mere concept on paper, the technology has just passed a rigorous six-month validation program. The physical design, echoed by all the media, consists of three interconnected hexagonal floating platforms that occupy about 1,200 square meters. But how does it supply power without collapsing? The system does not use huge generators to inject shock energy into the ship, but rather works on the premise of a “giant floating battery.” Through continuously operating 1.3 MW modular fuel cells (supported by up to 146 kW of onboard solar panels), the system slowly charges a massive 45 MWh battery bank throughout the week. When a ship docks, this battery releases energy quickly, delivering 5 MW of clean, continuous power without flinching. To fuel this process, the system consumes between 7,500 and 8,000 kilos of hydrogen per week. It has seven tanks on board integrated into low-pressure containers, which require refueling a couple of times a week. This allows ports to gradually adopt hydrogen without having to undertake extensive work to build pipelines or permanent storage facilities on land. The real impact. To ensure its real-world viability, the platform has undergone stability and wave testing in tanks at the University of Strathclyde, while industry giants such as Schneider Electric and Ricardo UK have successfully validated its entire complex electrical architecture. The environmental lights: According to the feasibility analyzes of the Ricardo consulting firm, the system can reduce emissions from docked ships by 77% compared to traditional diesel generation. In tangible figures, this represents a saving of about 47 tons of CO₂ per ship each week (almost 2,450 tons annually), in addition to completely eradicating emissions of toxic particles, nitrogen oxides (NOx) and sulfur (SOx) that poison the air in coastal cities. The shadow of cost: Today, this solution is more expensive than plugging into the conventional network. The estimated energy cost of this hydrogen hub is between £0.25 and £0.50 per kWh, compared to £0.15 – £0.25 for the traditional ground system. However, the consortium argues that this initial extra cost is offset by the astonishing speed of deployment and they anticipate that standardization and the future drop in the price of hydrogen will equalize the trade balance. The potential is immense. The consortium estimates a global market of 62 TWh annually for grid-independent maritime solutions, with the potential to avoid the emission of 500,000 tons of CO₂ in the next decade. Next stops. As detailed ELIRE Maritimethe consortium is already in commercial talks to start the first real deployments in first-tier ports such as London, Singapore, Hamburg, Brisbane and Riga. The future of maritime decarbonization seems to have found a shortcut. It is not about inventing exotic technologies from scratch, but about integrating what we already know works (hydrogen, batteries and electrical power systems) in a much smarter way. If the mainland does not have enough electricity to power the giants of the oceans, the solution, ironically, has always been to go back into the sea.

Star Catcher has raised $88 million to build the first space power grid. Their plan is to recharge satellites with lasers

by

As the pace of space launches increases and missions beyond Earth become more abundant and varied, it is important to look for new ways to obtain energy so that these ships can travel to their destinations. Fuel is not infinite, so there comes a point where it runs out. Therefore, there are three main proposals. One is to resupply the ships directly in orbit. Another option is to resort to nuclear energy. In fact, There are already several agencies working on it. Finally, there is the option of solar energy. Unfortunately, this has some limitations, but the American company Star Catcher wants to solve them through the world’s first energy network located in space. A good economic injection. Star Catcher just announced which has received 65 million dollars in a series A financing round. With what they already had in their coffers, the company has 88 million dollars. Enough to date its first release to the end of this year. Different ways to “squeeze” the Sun. The solar energy we are used to is obtained through plates with photovoltaic cells installed directly on the Earth. However, there are already companies that want to bring it directly from the Sun, even at night. Its goal is to use mirrors that reflect sunlight at will anywhere on Earth, whatever the time and whether the weather is good or not. The problem is that these companies They are being criticized a lot for posing risks such as great light pollution. On the other hand, what Star Catcher wants to do is slightly different. They will also take solar energy directly into space, but they will not direct it to Earth, but to the spacecraft that need it. It will be like a kind of space solar power plant. Optical beaming. Star Catcher will be based on a phenomenon known as optical beaming. This consists of extracting solar energy and using it to power a multispectral optical laser, with which it will be redirected to satellites from which it can be distributed at will to the ships that need it. To do this, they hope to be able to put a constellation of 200 satellites into low Earth orbit. Previous records. Last year, this company broke the world record for wireless electricity transmission by delivering 1.1 kW of power to NASA’s Kennedy Space Center. Now, they want to transmit directly to space. It also has limitations. Although this company does not have the same limitations as those that want to redirect sunlight to Earth, it involves placing an immense number of satellites in orbit, with the risk that this entails. Many experts warn that, in the same way that could happen with Elon Musk’s Starlink constellation, this type of infrastructure increases the risk of Kessler syndrome. That is, it could happen that one or more fragments of space debris collide with them, deteriorating and launching pieces into space that would become more space debris, which in turn would collide with more satellites or more debris. Thus, a very dangerous domino effect would be generated for satellites, ships and space stations that are in space at that time. Even more risks. On the other hand, the launches of the ships that will place the satellites into orbit are also a great source of pollution. In fact, recently has been published a study that warns of the large amount of polluting substances that these types of launches leave in the upper layers of the atmosphere, where, otherwise, the pollution would be residual. In short, this company will bring us great advances, but it will have to maneuver carefully so as not to bring even more problems.

As Europe builds data centers to achieve independence, its power grid enters the hunger games

by

Europe finds itself at a crossroads. If you listen to the CEO of Mistral, you should start investing big to stop being the technological vassal of the United States. That implies investing and part of that investment is in data centers. But American Big Tech is also moving and, if in the US they find frontal opposition to the construction of data centersthey move and there are countries like Spain that are favorite destinations. But there’s a huge problem: it’s not so much about money as it is about energy. And European macroplans are colliding with the reality of the electricity grid. Full speed ahead. The United States has the most brutal data centers on the planetbut Europe has a plan to arm itself and achieve that technological sovereignty. The plan goes through energy thanks to geothermal energy and, above all, renewables. Europe is a power in this and Spain has already shown its plumage to attract European and Big Tech data centers. esteem that there are 5,400 in the US and 3,400 in Europe, and Europe wants to close the gap. There is a very small problem: renewables are not enough to satisfy the voracity of data centers. We are constantly seeing it: data centers need constant power, but when they enter intense computing phases, the expense is so high that they need energy spikes that renewables cannot satisfy. That’s where they come into play. nuclear, gas and even coaland a Europe that cannot play that due to environmental policies is where it has its weak point. Spain. There are several points to analyze. As we say, Spain is one of the countries that is presenting itself as one of the best assets to host data centers. Aragon, specifically, is a community that is pushing hard in this direction and serves as an example. AWS is going to put some gigantic data centers in the community, adding more than 10,800 GWh of energy per year. To contextualize, it is more than all the current electricity consumption of the community. But it is not only happening in Aragon and the fear is that the saturated Spanish electricity grid will now have to deal with those data centers that they can collapse the network. He blackout ghost it’s still there and it’s already been warned in the Official State Gazette that an increase in installations that are not capable of withstanding voltage dips pose a very high risk for the network. the hunger games. Because first the principles of agreement came and, now, the different EU countries are realizing that, perhaps, it is not such a good idea. One of the most recent cases is that of Energinet, the state operator of Denmark’s electricity grid, which, in March, suspended all new large-scale connection agreements by receiving requests that would reach 60 GW, with 14 GW of them being for data centers. As in the case of Aragon, it must be put in context and, according to According to CNBC, the country’s maximum demand is 7 GW, so that total of 60 GW exceeds the country’s consumption almost nine times. It is not about canceling plans, but about an extension until we discuss what to do with that demand, but there are already those who point out that the extension cannot be ruled out because, simply, the country’s network may not be prepared. Estimation of increased energy demand for data centers FLAP-D. But they are not the only ones. Amsterdam, London or Dublin can no longer absorb the brutal energy consumption of artificial intelligence and the technology industry has set his eyes on the northern countries (in which wind energy is the protagonist) and in those in the south (with solar as a guest star). They are three important names because they are part of the FLAP-D, the conglomerate of Flankfurt, London, Amsterdam, Paris and Dublin that, historically, have been the dominators of the data center sector. Because these facilities have existed before the arrival of AI, but with the conversion to computing centers for AI is when their consumption has decreased. shot and when these metropolitan areas cannot meet demand. Those needs are so exaggerated It is estimated that data centers accounted for almost 80% of Dublin’s electricity consumption, forcing Ireland to impose a de facto moratorium on new data centers in its capital until 2028. braking. The situation, of course, is not the most promising for those who are building the AI ​​infrastructure at the moment. The boss of SMIC, one of the Chinese companies that is leading the country’s technological transformation, pointed out a few weeks ago that the AI ​​Big Tech companies are building all the infrastructure they will need over the next decade. in just one or two yearswhat is generating that plug in stock components worldwide. But then there is the energy plug which, as we see, is not small. And, obviously, it also generates delays in supply. According to the calculationsa decade to connect the new facilities to the electrical grid. If Microsoft, or whoever, builds a data center by 2027, but can’t pull the plug until 2037, something is clearly wrong. What is clear is that regulators are going to look at these projects with a magnifying glass because there is a physical limit that is that energy and connection requests. In fact, it is already recommended that before coming with a monstrous data center and then looking to see if there is a plug, construction plans take into account consumption and connection planning to national networks from the beginning. But there’s another problem: You can build a data center today that consumes x energy, but when you upgrade to more powerful platforms, those calculations may blow up. Either that… or self-powered data centers, as already stated made in Dublin. In Xataka | Data centers are real “heaters”. And they are settling in regions as hot as Aragón

We thought that AI was going to collapse the electrical grid. The solution is to “unplug” it 18 days a year

by

Daily headlines bombard us with the insatiable hunger for Artificial Intelligence, painting a future where data centers will devour our infrastructure. However, reality hides a fascinating irony: the same technology that clutters cables today could be our greatest ally. According to estimates of DeloitteAI will optimize global systems saving more than 3,700 TWh by 2030, almost four times the energy consumed by all data centers on the planet combined. But to get to that stage, you first have to turn on the machines today. And the solution is surprisingly analog. Paweł Czyżak, from the Ember analysis center and one of the most authoritative voices in the European energy transition, sums it up with a simple idea: A data center does not need to operate at full power every hour of the year. In the face of system collapse, the industry’s new survival dogma is clear: “Connect now and operate flexibly.” The heart attack of the network. We have been victims of what we once defined as “tyranny of 24/7”. Algorithms do not sleep and demand uninterrupted supply. This voracity has caused a heart attack in the traditional data epicenters in Europe (the “FLAP-D” markets: Frankfurt, London, Amsterdam, Paris and Dublin), almost completely paralyzing new deployments. The bottleneck is no longer the latest generation microchips; transformers and free electrons are missing. Added to this physical collapse is the bureaucratic one. The European University Institute (EUI) warns that connection queues are a critical funnel: in countries such as the United Kingdom or Italy, the requested capacity exceeds the peak of national maximum demand by more than 10 times. All of this is aggravated by speculative “zombie” projects that block entry to legitimate developers. The obstacles are, as detailed in the recent study by Camus, encoord and Princeton ZERO Laba double wall: there is a lack of cables for day-to-day operations and a lack of clean capacity built to provide backup. Flexibility as a lifesaver. Is it possible to “turn off” part of the AI ​​brain without the system crashing? Yes. A recent trial led by Nebius, Emerald AI and National Grid showed that an AI cluster was able to cut its consumption by 30% in just 40 seconds to relieve the network, keeping critical tasks intact. Even Google already boasts of having reached 1 GW of “demand response” by combining batteries and the ability to move loads between regions. As Czyżak explainsmoving just 5% of the load (the equivalent of a few critical hours per year) unblocks the grid massively. In fact, this strategy would save more natural gas than a country like Denmark consumes in electricity generation, by preventing electricity companies from having to turn on expensive and polluting combined cycle plants to cover demand peaks. For its part, the Camus and Princeton report proposes to scale this with two mechanisms: Flexible connections: The center operates normally 99% of the time, but in the scarce 40 or 70 hours a year of extreme network saturation, it reduces its computing or draws on its own batteries. BYOC agreements (Bring Your Own Capacity): Big tech finances its own clean energy capacity instead of waiting for the state to modernize infrastructure. The combination is magical: it reduces the wait to connect to the network from 7 to just 2 years. For a technology company, this means starting to bill three years earlier, generating net returns of between 1,000 and 4,000 million dollars per site. The citizen will not pay the bill. On a social level, the transition towards this flexible model brings excellent news for the average citizen. The detailed modeling of Princeton’s ZERO Lab confirms that a flexible data center (under BYOC schemes) assumes practically all of the incremental costs it generates to the electrical system. In other words, the billions needed to host the cloud will not be transferred to household electricity bills. On the contrary, by making the most of the existing network instead of building massive new lines, the fixed costs are distributed among more actors. In Spain, organizations such as the CNMC are already applying “flexible access permissions”forcing by law to accept controlled cuts in emergencies to protect the stability of the country. The plug that will rule the world. In the frenetic geopolitical and business race to dominate the future of Artificial Intelligence, the narrative has changed. It is no longer enough to design the fastest microchip or have the most brilliant engineers. Today absolute victory belongs to whoever has a free plug. But rather than desperately burning gas or waiting a decade for governments to bury thousands of kilometers of copper, the industry has found a pragmatic way out. Demand flexibility from Big Tech Not only does it allow them to turn on their servers years earlier; It protects citizens’ bills, squeezes the infrastructure of the 20th century and banishes the dangerous ghost of a Europe forced to relapse into its old addiction to fossil fuels.

The entire global electricity grid, in an impressive interactive map that shows the evolution of the energy transition

by

There are few infrastructures as complex and essential to living in the world as we know it as the electrical grid, which in practice for most mortals is reduced to touching a switch or connecting a plug to the socket and it works. Behind the world’s electrical infrastructure there is a huge conglomerate of equipment, careful planning and uses that are changing (among other things, due to the now so famous data centers). It is not the only thing that is being transformed: the energy transition is making it possible for those resources that once supplied the electrical grid to give way to renewable energies. But not all countries in the world have the same density of electrical networks or the same sources, because in fact there are real black holes in this very complete world map of the electrical network. Is called OpenGridWorks and is an interactive map of the entire world’s electrical infrastructure, from a small solar plant to the great lines that cross continents. And we already told you that it attracts attention not only for the beauty of the chromatic compositions, but also for practical purposes: from planning an engineering project to analyzing energy policy. Opengridworks This map is actually a web platform for geospatial visualization of electrical infrastructure. All its data comes from OpenStreetMap, the world’s largest open, collaborative geographic database, maintained by volunteers and experts on an ongoing basis. This guarantees global coverage, constant updating and completely free access. But for network and infrastructure data it uses information from Global Energy Monitor or the United States Energy Information Administration, among others. Its purpose is to show, in a clear and interactive way, where electricity is generated, how it travels through the grid and where consumption is concentrated. It is worth stopping at the layers and all the information it shows because as we warned you before it is very complete, so if you leave all the options activated you will find yourself in a mess. If you move on the map and get closer, you will be able to see information such as: What technology provides the energy in the form of a colored bubble: blue for hydroelectric, red for thermal, yellow for solar, green for wind and purple for nuclear. The size of each bubble represents the installed capacity in MW Transmission lines are drawn thicker the higher their voltage (from 100 kV to 765 kV) and substations appear as nodes where these lines converge. Data centers also appear in the shape of a white diamond as they are points of intensive consumption. On the other hand, easement strips (ROW) appear as shaded areas around lines and facilities. Opengridworks But you will also be able to see additional information when you hover the pointer over any of the points. An example: when touching the Montes de Cierzo wind farm in Tudela, we will see that it is in operation and the energy it provides. What the global electrical map reveals about the energy transition Playing with the zoom and scrolling you quickly discover that there are areas of saturation and others that are a desert of infrastructure. From an engineering point of view, the map allows you to search for the closest interconnection point for a new project or detect nodes whose failure would leave regions without supply. Beyond engineering, it is an energy policy tool: it highlights the electrification gaps in developing countries, shows the real progress of renewables compared to fossil fuels, and allows the resilience of different national networks to be compared. AND abysmal differences are observed. Opengridworks The densest networks They are concentrated in the United States, central Europe and China, while sub-Saharan Africa and central Asia show very poor coverage that reveals an electrical blackout. In South America, the areas with the most infrastructure are on the Atlantic coast, although there are also some timid points on the Pacific coast. However, inside we barely find more than a fade to black. The colors of energy sources also change on the map, still dominated by thermal generation, although in Western Europe and China the advance of solar and wind power is a reality already perfectly visible. This map also reveals curiosities such as that nuclear plants always appear next to rivers or coasts due to cooling needs and hydroelectric plants are concentrated in the large river systems of the world. The data centers are also not placed at random, but are clustered near large transmission nodes to ensure supply.

We had a perfect plan to decarbonize the electrical grid. The brutal consumption of data centers has dynamited it

by

The daily headlines multi-million dollar investments announced in new language models and cutting-edge chips. Venture capital investors have pumped more than half a billion dollars into AI startups over the last five years. But, as a revealing analysis warns of TechCrunchthe smart money has begun to change sides: today, the best investment in Artificial Intelligence is no longer software. The reality on the ground has become extremely arid. Putting up walls and stacking servers in a giant data center has become the easy part of the equation. The real wall the tech sector is crashing into is finding the electrons needed to power it. According to a report by the analysis firm Sightline Climateup to 50% of data center projects announced for 2026 could face delays. Of the 190 gigawatts (GW) of capacity the company tracks globally, just 5 GW are under actual construction today. The bottleneck is no longer the microchips. It is access to the electrical network. The tyranny of 24/7. Consumption has run amok at a pace that 20th century infrastructure cannot process. A Goldman Sachs analysis projects that AI will shoot energy consumption of data centers by 175% by 2030. The figures all point in the same direction: the Open Energy Outlook predicts that electricity demand combined data centers and crypto mining will grow by 350% this decade. As a result, the pristine image of the technological cloud is evaporating. Google’s emissions have increased by 48% in the last five years, and Microsoft’s by 31% since 2020. The reason? What is known in the industry as the “tyranny of 24/7”. The algorithms do not sleep and require a continuous and steady power supply; They cannot be turned off simply because the wind stops blowing or the sun sets. Given the lack of mass storage systems globally, the fuel that is covering this urgent gap is not green. It is natural gas, which has returned from retirement as the great structural support of the sector. A global collapse with two faces. The pressure has already broken the market balances. In the PJM region—which supplies 13 eastern US states and has the highest density of data centers in the world—capacity prices went from $30 to $270 in a single auction at the end of last year. As John Ketchum, CEO of NextEra Energy, noted, we are facing a “golden era of energy demand”, but with an insurmountable physical limit: “the new electrons cannot reach the network quickly enough.” This electrical asphyxiation is redrawing the global map, and Europe is the best example. Historically, the European market was dominated by the “FLAP-D” markets (Frankfurt, London, Amsterdam, Paris and Dublin). But the network of these cities is no longer going strong. According to data from Greenpeacedata centers accounted for almost 80% of electricity consumption in Dublin, forcing Ireland to impose a moratorium. The market share of these traditional capitals will fall sharply by 2035causing a mass exodus to the Nordic countries (with unburdened networks and cold climates) and to southern Europe, such as Spain, Greece and Italy, in search of green megawatts. The hardware and network problem. When we scratch beneath the surface of this collapse, we discover that the physical problem splits into two large gaps. First, the machine to generate the energy is missing. Since intermittent renewables are not enough, companies turn to gas. However, gas turbines have become a rare commodity. Three years ago, Siemens Energy executives considered this market “dead”; Today, the factories are so overwhelmed that the delivery times for these turbines can extend up to seven years. Second, the “plumbing” is missing. Once the electricity is generated, the task of taming it within the building falls to the transformers. It is an iron and copper block technology that has barely changed in 140 years. As explained TechCrunchAs servers demand more power, traditional electrical equipment will take up twice as much space as the servers themselves. It is mathematically unsustainable. ‘Smart Money’ changes sides. Against this backdrop, venture capital is pivoting. Big tech companies (Amazon, Google, Oracle) are starting to behave like energy giants, devising alternatives to minimize their dependence on an outdated public grid through hybrid or generation approaches. on site. The solutions are divided into several fronts: The nuclear resurgence: Google has signed a pioneering agreement with Kairos Power to develop seven small modular reactors (SMR) by 2030, and Amazon tried (although regulators temporarily blocked it) connecting a data center directly to the Susquehanna nuclear power plant. Super batteries: Google is collaborating in Minnesota with the company Xcel Energy and the startup Form Energy to install batteries capable of discharging energy for 100 hours, thus stabilizing the peaks of renewables. Hardware innovation: Dozens of startups (such as Amperesand or DG Matrix) backed by investment funds are developing silicon-based “solid state” transformers, seeking to finally retire old iron and copper to save vital space in facilities. Regulatory surgery: In southern Europe, organizations such as the CNMC in Spain are applying “flexible access permits”, forcing centers to accept cuts in emergencies so as not to collapse the entire country. The paradox: AI as savior of the electrical system. However, the story has a fascinating twist. The same technology that today threatens to burn the cables of half the world could be the one that ends up saving the electrical system. According to the consultant’s estimates Deloittethe application of artificial intelligence to optimize industrial systems and electrical networks will save more than 3,700 TWh globally by 2030. That is, AI will save almost four times the energy consumed by all the data centers on the planet combined. A report of Ember over Southeast Asia (ASEAN) support thiscalculating that integrating AI into the management of its networks will save more than 67 billion dollars and avoid the emission of almost 400 million tons of CO2. But to get to that future of efficiency, you first have to turn on the machines today. And what is at stake is the world economic map. Hosting these centers is … Read more

Spain had a completely saturated electrical grid. And then data centers arrived to blow it up even more

by

Imagine a highway on which not a single vehicle can fit anymore. But the problem is not that there is a lack of asphalt, but that the cars do not know how to drive efficiently and keep kilometer-long safety distances. The Spanish electrical grid was exactly that. It had been operating for years at the limit of its administrative capacity, and suddenly, a convoy of trucks of industrial tonnage and voracious appetite has arrived at the access ramp: data centers. These megainfrastructures, pillars of artificial intelligence and the cloud, promise to water the economy of millions, but their brutal need for supply threatened to burst the seams of an already saturated electrical system. To avoid collapse and not let the reindustrialization train escape, the Government has had to react and radically change the technical rules of the game. Cascading capacity collapse. To understand the collapse we have to look at how our way of consuming energy has changed. The energy transition is profoundly reconfiguring the model throughout the national territory. Requests to connect to transportation and distribution networks have skyrocketed. In addition to the electrification of industry and renewable hydrogen, there is now massive consumption associated with data centers for artificial intelligence. The problem broke out when the National Markets and Competition Commission (CNMC) established a “dynamic criterion” to calculate how much access capacity was available in the areas shared by several network nodes. As detailed by the Ministry for the Ecological Transition and Demographic Challenge (MITECO) in his press releaseapplying this criterion means that a single access requested at a node can cause a “cascading effect that drains capacity in the rest of the nodes that share the area”, blocking requests from dozens of kilometers away. Basically, a large data center asks for passage and, automatically, the system administratively blocks neighboring nodes as a precaution, even if physically the cables have plenty of space. Investments in the air and the ghost of the blackout. The consequences of this traffic jam directly affect the real economy and national security. Real estate and industrial paralysis. The situation is so critical that, as we already mentioned in our previous coverage citing the Asprima employers’ associationlast year only 12% of connection requests for new urban developments were granted. There are 350,000 homes at risk simply due to lack of electrical power. The risk of an electrical “zero”. The Official State Gazette warns that the increase in installations that are not able to withstand “tension gaps” poses a very high risk. If there is a disturbance and these generators are massively disconnected, exchange flows are produced that are incompatible with Spain’s limited interconnections with Europe. As the diary recalls The Countrythe objective is to avoid at all costs a repeat of massive blackouts like the one suffered by the Iberian Peninsula on April 28, 2025. It is not enough to put more cables. In areas limited by this dynamic criterion, it is no longer possible to enable new capacity simply by investing money in reinforcing the network with “more copper.” The expert in the sector Joaquín Coronado sums it up perfectly: the demand must be 100% active; It must provide flexibility and commit to the stability of the system. The Government’s emergency surgery. To unclog this Gordian knot, the Government and regulators have launched a three-way shock plan: The new Royal Decree of MITECO. The Ministry has been brought to public hearing (until March 16) a standard that updates the technical requirements to connect to the network. The master key is that now it is required that the demands “withstand voltage gaps”, do not introduce adverse oscillations and maintain the quality of the wave. By forcing installations not to disconnect in the event of small disturbances, the number of nodes affected in shared areas is reduced. This simple technical measure could bring out 50% more capacity in about 900 knots of connection to the high-voltage network. The “flexible permits” of the CNMC. To put an end to the binary model (either I give you all the capacity or I deny it), the CNMC has proposed four new types of permits, as we already broke down in Xataka. These range from allowing consumption only in certain time slots, to “dynamic” permissions where the operator can remotely disconnect a data center if there is an emergency on the network. The “technical amnesty” for data giants. In parallel, the Ministry of Industry has been urgently removed the “off-peak” requirement. Previously, to receive aid, you had to consume at night, an absurdity for a data center (which operates 24/7) and for today’s Spain, where solar energy has brought down prices at midday. The citizen cost and the fine print. The Government’s maneuver not only responds to a national emergency, but also places Spain as a pioneer on the continent. The country is anticipating the update of the European network codes, deploying a battery of technical specifications simultaneously that is already considered a milestone worldwide, as detailed The Country. In this deployment, the new regulations also settle a historical debt with energy storage: batteries will finally have their own specific regulatory framework, no longer being administratively treated as simple “generation by analogy” facilities. However, this deep digitalization so that the network supports such a complex mode of operation will not come for free, and the bill for modernization will end up looming in the consumer’s pocket. Forecasts for 2026 They already estimate direct increases in citizen receipts, with a 4% increase in tolls and a not inconsiderable 10.5% in electricity system charges. And while citizens assume the technical cost, the data giants – recipients of this regulatory red carpet – prefer to remain cautious in the face of the eternal Spanish bureaucratic obstacle. The technology sector warns that a key piece of the puzzle is missing: If the Government does not expressly include the National Code of Economic Activity (CNAE) corresponding to “Data Processing” in the official list of sectors entitled to receive the million-dollar electro-intensive aid, all … Read more

its electrical grid claims to be “full” when in reality it is underutilized

by

Spain is experiencing an obvious and costly energy paradox. While the country breaks renewable generation recordsits electrical system suffers an administrative “thrombosis” that threatens to stop reindustrialization. The problem is that the system works like a broken bridge: clean energy is born in the so-called “emptied Spain”, but there are not enough cables to take it to the cities and factories where consumption is concentrated. The panic in the sector reached its peak when the National Markets and Competition Commission (CNMC) was forced to postpone three months (from February 2 to May 4, 2026) the publication of the access capacity maps after a critical alert from Red Eléctrica: under the new security criteria, approximately 90% of the network nodes would appear in “red”, that is, with zero capacity. However, the network is not physically collapsed, but administratively “full” and underutilized in practice. To solve this funnel, the CNMC has put on the table a master plan that will change the rules of the game: flexible access permissions. The perfect storm. Getting to this point has not been the result of a single mistake, but rather a cocktail of bureaucratic slowness, territorial imbalances and speculation. As we have already advanced in Xataka, There is a huge gap between administrative times and physical execution: building a substation barely requires a year of work, but its prior processing can take between three and six years. Added to this is that we have installed windmills and solar panels where there is land and resources, but demand is growing in metropolitan areas that do not have sufficient infrastructure, leaving 83.4% of distribution nodes saturated currents. The consequences on the street are devastating. Last year only 12% of connection requests for new urban developments were granted, which, according to the Asprima employers’ associationputs the construction of 350,000 homes at risk due to the simple lack of electrical power. And in the midst of the chaos, the bubble: there are access requests for 67,100 MW (half of all the installed power in the country), which makes the regulator suspect the existence of “ghost” projects that hoard nodes only to resell the permits. The end of the binary model. Until now, the electrical system operated under a binary principle: either they gave you firm access, 100% guaranteed, or they denied it. However, as he noted on his social networks the Secretary of State for Energy, Joan Groizard, the current network is underused; In fact, a “smaller” network in the past supported demand peaks much higher than today. This is where the regulatory revolution comes in. The CNMC proposal breaks with the resounding “no” and establishes that, if there is residual capacity at certain times of the day or year, it can be shared. Flexible access capability assumes that supply will not be guaranteed at all hours of the year, maximizing the use of existing infrastructure without immediately resorting to massive investments that citizens would end up paying for. The four ways of flexibility. To articulate this new paradigm, the supporting report and the proposed resolution of the CNMC define four types of permits Flexible access, adapted to different needs: Permission Type 0 (Fixed pattern in Distribution): Applies to installations connected to any voltage level in the distribution network. It allows energy to be consumed following a fixed time pattern (for example, from 00:00 to 07:59 and from 11:00 to 17:59), which represents at least 62.5% of the hours of the year. Outside of these ranges, if the installation consumes power, the network manager (GRD) can disconnect it remotely without prior notice. It is ideal for those who can plan their production. Type 1 Permit (Remote disconnection due to contingency N-1): Designed for distribution installations with voltage greater than 36 kV. The installation meets the requirements under normal conditions (with an expected consumption of 90% of the year), but agrees to be disconnected remotely and without prior notice if any element fails in the substation itself to which it is connected. Type 2 Permit (Dynamic Instructions in Distribution): For voltages greater than 36 kV and powers greater than 1 MW. It is the most technologically advanced, the installation must be able to receive dynamic instructions from the GRD to reduce its load, whether scheduled the day before or in real time. Response times are critical: less than 30 minutes if it is preventive, or less than 3 minutes (immediate) if it is corrective. If you disobey, you will be disconnected. This model will come into force from January 1, 2028. Type 3 Permit (Transmission with automatic reduction): Aimed at demand installations of more than 1 MW connected directly to the transmission network. These facilities are required to participate in the Automatic Power Reduction System (SRAP). In the event of a security alert from the electrical system, the operator (OS) will send a signal and the installation must reduce the power associated with its flexible access to zero effectively and immediately. Winners, exceptions and the bill. This regulatory change has clear winners and some red lines. Storage facilities in demand mode are the perfect candidates, since, by law, they have no guarantee of supply and will have 7 months to request the modification of their permits. At the opposite extreme, the CNMC explicitly prohibits granting these accesses to essential supplies (such as hospitals), to demands that do not support 24 hours without a network, and to collective projects such as urban plans. Modernizing the network to support this “reinforced mode” of digitalized operation will have a direct economic impact. The forecasts for 2026 point to increases in citizen receipts of 4% in tolls and 10.5% in charges to finance system adjustments. For now, the clock is ticking: the public hearing process for agents to send their allegations to the CNMC proposal will end on March 20, 2026. Connect the future. Spain finds itself at an ironic and dangerous crossroads. The country has everything to be the great green battery of Europe, but the lack of cables and excess bureaucracy … Read more

NATO’s notice to shield our electrical grid

by

The blackboard hanging behind the bar at Squat 17b, a venue in kyiv, does not list drink offerings, but instead keeps a countdown of the days Ukrainians must endure the harsh winter. Inside, the bar lacks electricity and is illuminated only by candles, while customers shiver on stools drinking beer cooled by the freezing temperatures themselves. This print, described by Financial Timesis the result of an exceptionally harsh winter, with temperatures reaching -20 degrees Celsius. What is emerging in Eastern Europe is a reality that some analysts They already describe how “thermal terror”: the cold turned into a weapon of war. Russia does not merely seek to degrade Ukrainian military capabilities; It deliberately targets substations, power plants and distribution networks to make everyday life physically unfeasible. Heating, electricity and water become strategic objectives. Away from the trenches, the front line has moved to the transformers and electrical substations. In the first weeks of the year, Russian forces They have attacked the Ukrainian energy sector more than 200 times. Russia has launched coordinated waves of up to 40 missiles and 400 drones in a single night, seeking to overwhelm air defense systems. Ukraine lost up to two-thirds of its electricity generation capacity after the first months of bombing. And yet, the infrastructure resists. The new frontier of sabotage Faced with the increase in physical and hybrid threats, the European electricity industry has begun to issue clear warnings. “The last year has shown us that continuing with the current model in Europe is no longer an option,” said Leonhard Birnbaum, president of Eurelectric, in statements collected by Euronews. For the sector, security of electricity supply It has become a strategic issue. At the end of December, Poland’s security systems they detected what his Government described as “the strongest attack against Polish energy infrastructure in years.” The Sandworm group—a unit linked to the Russian GRU—managed to disable remote terminal units (RTUs) at at least 30 energy facilities. These RTUs do not generate electricity, but they allow substations and plants to be monitored and controlled. The attack affected plants cogeneration and systems that connect wind and solar farms with the grid. To achieve this, they used a destructive malicious code known as wiperdesigned exclusively to delete files and permanently render computers unusable. Polish Prime Minister Donald Tusk warned thathad it been completely successful, half a million people would have been left without heat in the middle of winter. This use of a wiper marks a qualitative leap: Russia has gone from simple digital espionage to destructive sabotage against critical infrastructure of a NATO member country. Physical espionage is added to the cyber threat under the sea. The Russian spy ship Yantaroperated by the Russian Deep Sea Research Directorate (GUGI), traveled for almost 100 days through the waters of the Atlantic and the Mediterranean. Their goal was to map and monitor the undersea cables that Europe and North America depend on for their digital communications and energy. These types of covert operations in the “gray zone” seek to measure NATO’s red lines and open the door to possible power or communications outages to force political negotiations. How did we get here? As the historic American general Omar Bradley recalled: “Amateurs talk tactics, professionals talk logistics.” For any developed nation today, the most critical logistics system is its energy infrastructure. For decades, Europe built a deeply dependent on imported fossil fuels. Dependency became vulnerability. As he remembered Bloombergthe European Union paid almost €22 billion in Russian fossil fuel imports last year, more than it provided in direct financial support to Ukraine. Changing models has ceased to be a climate issue and has become a pure survival instinct. The old continent has proven that filling its territory with renewable sources and electrifying the economy builds a much more solid structural wall than the old addiction to foreign fossils. And the shield is already working. A look at the data collected by the think tank Agora Energiewende In his latest report, Europe’s energy security on the path to climate neutrality, reveals a brutal cushion: the simple deployment of wind and solar technology during the last five years (2019-2024) avoided having to buy and burn 92 billion cubic meters of gas. However, this transformation introduces new risks. Modern power grids are more digital, more interconnected and more decentralized. According to the same report Agora Energiewendethe challenge is no longer just to ensure fuel supply, but to guarantee network stability, cybersecurity and industrial resilience. More nodes mean more potential entry points for attacks. Added to this is the technological dimension. How to collect Euronewsbetween 70% and 80% of the solar inverters installed in Europe come from Chinese manufacturers such as Huawei or Sungrow. In a highly digitalized system, hardware control also potentially implies software control. Energy as defense policy Faced with this vulnerability, Europe is obliged to treat energy security as a defense policy de facto. A coalition of defense experts, including retired military leaders such as British Lieutenant General Richard Nugee and Dutch General Tom Middendorp, has urged European governments to count low-carbon energy spending against NATO’s target of allocating 1.5% of GDP to critical infrastructure and civil resilience. In statements collected by Guardianretired Lt. Gen. Richard Nugee said, “To have a strong military deterrent we need a resilient homeland. And low-carbon energy is a critical component.” According to Bloombergthis vision is gaining ground in the European strategic debate: the energy transition is no longer just climate policy; is security architecture. The tactical key to this new defense is decentralization. Unlike large centralized plants that are easy targets for missiles, wind turbines and solar panels are much more geographically dispersed, making them significantly less vulnerable to large-scale attacks. To sustain this new model, Euroelectric proposes three fundamental pillars: Better planning: Preparedness frameworks should span the entire value chain, include all energy carriers, and anticipate long-term external threats. Massive flexibility: It will be essential to deploy new storage and demand management technologies to complement the variability of renewable energies. … Read more

Russia’s elite GRU moves its war against Ukraine’s power grid to Polish soil

by

Winter in Eastern Europe is not just a season; It’s a damage multiplier. As my colleague Miguel Jorge described wellwhat is emerging in the region is a ruthless reality dubbed “thermal terror.” In this scenario, extreme cold becomes a weapon of war designed to make civil infrastructure – heating, electricity, water – the cruelest target. The ultimate goal is not only to destroy military capacity, but to make daily life physically unviable. Under this logic of making daily life unviable to wear down the population, the Kremlin’s most feared cyberespionage group has decided to cross a dangerous border. 500,000 homes in the spotlight. As Poland prepared for the holidays, its security systems detected what Energy Minister Milosz Motyka called the “strongest attack against Polish energy infrastructure in years,” as reported by Reuters. The sabotage occurred on December 29 and 30 and was surgical. The targets were not chosen at random, but instead targeted two cogeneration plants and systems that connect renewable energy facilities — such as wind farms — to power grid operators. In other words, directly to the key nodes so that energy reaches homes. local media they collected the statements from Prime Minister Donald Tusk, who put figures at risk: if the attack had been successful, half a million people would have been left without heat in the middle of winter. Fortunately, as detailed in the press release of the Polish Governmentthe defenses worked. “At no time was critical infrastructure threatened,” said Tusk, although the incident has been treated with the utmost seriousness, mobilizing the special services to their full capacity. Sandworm’s signature. The attack took on an international dimension when the cybersecurity firm ESET announced the discovery of the weapon used: a destructive malware called DynoWiper. As reported by TechCrunchESET attributed this operation with “medium confidence” to the Sandworm groupan elite unit within the Russian military intelligence agency (GRU). The choice of dates does not seem coincidental. As investigative journalist Kim Zetter points outthis attempted blackout in Poland came almost exactly ten years after the first Sandworm cyberattack against Ukraine’s power grid in 2015, which left 230,000 homes in the dark. For experts, the use of a wiper on Polish soil is an unprecedented event, as it marks Russia’s move from simple espionage to destructive sabotage against a NATO member. Furthermore, this is not an isolated episode because since the beginning of the Ukrainian War, Poland has undergone a sustained increase of cyberattacks attributed to Russian actors. Nevertheless, according to the Ministry of Energy itselfthe December attempt was a turning point both in its intensity and in its objective: it was no longer about probing defenses, but rather about causing a real blackout. Anatomy of the attack. To understand the seriousness of the issue, it is necessary to break down the technology used. Unlike the ransomware commona wiper It is software designed exclusively to destroy. Your goal is not to ask for a ransom, but delete permanently information and leave equipment unusable. In this case, the attackers went directly to the ICS (Industrial Control Systems) systems since these systems are the ones that allow electric companies regulate the supply and monitor the network. So, Sandworm sought to break communication between renewable energy sources and distribution operators. When attacking these nodes, the technicians’ margin of action is minimal because the failures propagate in a chain. A conflict that expands. The Polish Prime Minister directly linked this attack to his country’s support for Ukraine. “We sell electricity there and, in critical situations, we receive it from them,” Tusk explained.. Attacking the Polish network is, by extension, attacking Ukraine’s energy rear. This Russian aggressiveness is not new for Western intelligence services. In fact, the United States government keeps a reward 10 million dollars for information about six GRU officers belonging to Sandworm, responsible for global attacks such as NotPetya, which caused losses of 1 billion dollars. According to Microsoft, Sandworm—whom they call Iridium— has launched nearly 40 destructive attacks against critical infrastructure since the beginning of the invasion of Ukraine, seeking to degrade not only military capacity, but the population’s trust in its leaders. From NATO’s point of view, attempted sabotage does not automatically activate collective defense mechanisms, but it does reinforce disturbing evidence: hybrid warfare makes it possible to strain the European system without formally crossing the red lines of an armed conflict. The next frontier is no longer territorial, but digital. Faced with the growing threat. The Polish Government is finalizing the Law on the National Cybersecurity System, a regulation that seeks the “autonomy and polonization” of security systems to reduce dependence on devices that facilitate foreign interference, according to official information. However, December’s failed sabotage is a reminder that in modern warfare, the front lines are on power plant servers. While in the trenches of Ukraine soldiers try to hide their thermal trace from drones, in cities like Warsaw or Krakow the battle is being fought so that the simple act of turning on the heating does not become an impossible luxury. For now, Poland has won this defensive battle, even achieving a historical record of energy production a few days after the attack. However, Sandworm’s shadow is still long. The hackers’ message is clear: “If we can’t turn off the light, at least we can scare you.” The war for control of the European switch has only just begun.
