Dutch datacentre sector pitches itself as reduction for an overloaded grid
The Netherlands has no scarcity of electrical energy – however what it does lack is the grid to hold it. On the finish of 2025, greater than 15,000 functions from companies and establishments have been queuing for a brand new or heavier connection to the regional grids, in response to the Dutch authorities. Wind and photo voltaic farms generate energy in locations the place no one makes use of it, whereas the cities and enterprise parks that want it are caught with a community that can’t take any extra.
The sector typically blamed for the grid strain can in actual fact assist relieve it, say Europe’s datacentre commerce associations – not by utilizing much less electrical energy, however by utilizing it the place it’s generated. Representatives from the Netherlands, Eire, Sweden, France and Italy made that case throughout a panel at Vertiv Week 2026, the annual EMEA occasion of US energy and cooling provider Vertiv, in Zagreb.
Stijn Grove, managing director of the Dutch Knowledge Middle Affiliation, defined how that might work. Offshore wind farms within the North Sea are struggling to broaden as a result of there’s not sufficient demand for the facility they produce. With out new consumers, there aren’t any new energy buy agreements, and with out these, there isn’t any financing. The Dutch authorities’s final zero-subsidy tender, for the 1GW Nederwiek I-A web site, drew no functions in any respect, with rising prices and decrease electrical energy demand than anticipated cited as the explanations. And the facility that’s produced comes ashore on the coast, the place hardly anybody wants it.
“So, now the grid operator has to rebuild its entire community to move that energy to a very completely different location,” Grove mentioned.
That’s the reason TenneT, the Dutch nationwide grid operator, is now asking the sector whether or not it will possibly assist at these coastal websites. The logic is simple – a datacentre subsequent to a touchdown level makes use of the facility on the spot. The grid operator not has to maneuver it throughout the nation, which frees up capability on the present community for different customers. Grove added that the sector might carry greater than demand alone. “We’re a high-margin enterprise, so we’re keen to put money into this sort of state of affairs to broaden the grid.”
Ronan Kelly, CEO of Digital Infrastructure Eire, sees the identical sample at house. Eire has one of many highest numbers of datacentres per capita on the earth, however the touchdown stations for offshore wind usually are not the place these datacentres are. The Irish authorities’s Massive Vitality Consumer Motion Plan, printed in January, goals to appropriate that mismatch by steering new datacentres in direction of areas with renewable technology.
Kelly additionally pointed to battery storage, which the Irish market more and more makes use of to bridge dips in wind and photo voltaic output. And since datacentres have already got backup capability and may generate their very own energy, he believes they may assist the grid when it’s underneath pressure. “There’s a future function for datacentres in stabilising the grid,” Kelly mentioned, “in order that when it comes underneath strain, the datacentres related to it will possibly assist bridge a part of the vitality scarcity.”
Warmth as foreign money
Consuming energy domestically is a method datacentres can relieve the grid, and their waste warmth is the opposite. In De Kwakel, a Dutch village in the midst of the Greenport Aalsmeer horticultural space, Change Datacenters and dozens of growers signed an settlement for a warmth community fed by a brand new datacentre. It’ll provide warmth to the greenhouses, and the greenhouses will ship chilly return water again to chill the it. Analysis by Dutch regional grid operator Liander discovered that with out it, each grower would want its personal warmth pump to maneuver off gasoline, placing much more pressure on a regional grid that’s already congested and has little bodily room to broaden.
In Rotterdam, operator Smartdc runs a datacentre within the former logistics constructing of the Van Nelle Manufacturing facility, a Unesco World Heritage web site that’s house to greater than 100 firms, and provides warmth from its servers to the remainder of the complicated. The monumental buildings used round 800,000 cubic metres of gasoline a 12 months. Because the datacentre changed its typical cooling items with warmth pumps that carry server warmth to the places of work, their gasoline use has fallen by 80%.
Isabelle Kemlin, vice-chair of the Swedish Knowledge Middle Trade Affiliation, pointed to comparable initiatives in Sweden: warmth provided to district heating networks, waste warmth used to dry wooden for native heating vegetation, and a datacentre in Boden that heats a greenhouse the place the municipality supplies jobs for individuals who discover busy workplaces tough.
“However that solely works if municipalities sit down with the operator from the beginning,” Kemlin mentioned, “not as soon as the datacentre is already there.”
The European Fee (EC) estimates that reusing round half of all datacentre waste warmth in Europe would cowl the heating demand of 4 million households.
Nuance within the measurement
The day earlier than the panel, the European Fee introduced a ranking scheme for datacentres. Very like the vitality label on a washer, it would charge datacentres above 500kW on the vitality and water use they already report underneath the Vitality Effectivity Directive, with the primary labels anticipated in 2027. The EC’s first report on vitality effectivity places the common Dutch datacentre at an influence utilization effectiveness (PUE), the usual measure of datacentre effectivity, of 1.17, which the EC charges as glorious, and a water utilization effectiveness (WUE) of 0.70. These figures relaxation on a slender base, nonetheless: throughout the EU, solely round 36% of the datacentres required to report really did so.
Grove welcomed the initiative, however was fast so as to add a caveat: “The thought of monitoring and exhibiting individuals how good your infrastructure is, that’s not a nasty thought. However are you able to seize all these nuances in a small sticker with some information and a few colors? I’m not likely positive.”
Water is a living proof. The place water is plentiful, cooling with it’s cheaper and extra environment friendly than utilizing electrical energy, Grove defined, whereas in water-scarce areas operators go absolutely electrical. On paper that may seem like poor efficiency, though it’s the proper selection.
Michaël Reffay, managing director of France Datacenter, was extra wholehearted in his assist. “It will increase transparency, and transparency means acceptability,” he mentioned, though he warned that the scheme should not change into a aggressive drawback in contrast with the US and China.
Grove additionally pointed to a paradox that sums up the entire debate. A datacentre that provides waste warmth to its environment wants a warmth pump to take action, and there’s nonetheless no settlement on whether or not that further electrical energy ought to rely in direction of its PUE.
“If it does, the PUE will get worse,” Grove mentioned, “however really, you’re offering warmth to any person else.”
The label does take this into consideration, because it additionally information a datacentre’s contribution to the grid, together with warmth reuse. However as soon as the labels seem, it’s the letter that makes the headlines, not the small print.
The underlying information can also be removed from dependable. Researchers on the College of Stuttgart present in July that a number of the figures provided have been plainly incorrect: Danish datacentres, for example, would have been working at 140% of their capability, which is unimaginable.
Companion or burden
The panel closed on a be aware of urgency. Kelly described the present funding wave as the biggest the world has ever seen. “We’ve the chance to construct probably the most safe and the greenest AI infrastructure on the earth,” he mentioned. “However we’ve got to know it shortly, as a result of the trade gained’t await us.”
The chance could also be there, however the highway is much from clear. Between classes, Kelly acknowledged that working with grid operators will be arduous going. In Eire, the place the grid operator is a state-owned firm that grew out of the outdated mixed grid builder and operator, it tends to work at its personal tempo and doesn’t like being pushed, and affords of assist from the sector typically get a lukewarm reception. Nor do grids have capability to spare.
Kelly, who labored within the UK for 2 years earlier than becoming a member of DII, sees the identical strain there because the UK tries to seize as a lot of this funding as it will possibly. “As quickly as you open the doorways and say, “Come right here, we’ve received vitality’, the builders arrive in 100-megawatt chunks. Earlier than you already know it, it’s all gone.”
Public notion is one other impediment, and one Kelly known as “completely an issue”. Till there’s demonstrable proof that datacentres don’t hurt their environment, he mentioned, a adverse picture is tough to reverse.
For Reffay, the unease begins with AI itself: “Proper now, AI is generally delivering nervousness.” In his view, notion will solely change as soon as the know-how delivers tangible advantages to massive teams of individuals.
Kemlin went a step additional and turned the argument round: Europe already has an electrical energy infrastructure, and is now constructing a second one. “It’s not simply one other large client of electrical energy,” she mentioned. “It’s the new infrastructure.”
For Grove, it in the end comes right down to a political selection. “It’s good that we dwell in Europe, the place there’s regulation and there are boundaries on development,” he mentioned. “However the course of our economic system is digital. Europe, and the international locations inside it, have to decide to put money into the infrastructure the economic system of the longer term wants.”
