Data Centres in the Netherlands: From Amsterdam Boom to Hyperscale Moratorium

The Dutch data-centre story is a parable of infrastructure success turning into infrastructure scarcity: the country built the best digital plumbing in Europe and then ran out of the electricity to use it. With more than 180 commercial data centres, over half of them around Amsterdam, and hyperscale campuses for Microsoft and Google in the polders of North Holland and Groningen, the Netherlands hosts a disproportionate share of Europe’s cloud. Since 2019 it has also been the first country to say no: first Amsterdam and Haarlemmermeer, then the national government after the Zeewolde affair, then Amsterdam again in 2025 as grid congestion threatened housing. This article explains how the boom happened, why Meta was turned away, what the moratoria and the hyperscale rules actually say, how grid congestion now shapes every project, and what the 2025 and 2026 wave of northern and Amsterdam projects means. It is part of the Netherlands Company Stories hub.

How did Amsterdam become one of the world’s largest internet hubs?

Amsterdam became an internet hub because Dutch academics and ISPs built a neutral place to swap traffic before anyone else in continental Europe did. The Amsterdam Internet Exchange began in the early 1990s at the NIKHEF physics institute and the SARA computing centre on the Science Park, connected to CERN in February 1994, and was formalised in 1997 as the AMS-IX Association, a non-profit owned by its 20 founding members. Because it was neutral, non-commercial and run by its members, every carrier, content network and cloud provider that wanted European reach connected, and the exchange grew from 12 gigabits a second of peak traffic in 2002 to 1.5 terabits in 2011, 5 terabits in 2016 and more than 15.8 terabits a second at its 2026 peak, with 904 connected networks.

Data centres cluster around exchanges because latency is distance. Equinix, Digital Realty (through Interxion), Iron Mountain, Global Switch, NorthC and others built around the AMS-IX points of presence, of which there are 16 in the greater Amsterdam and Rotterdam area, and the region’s fibre density attracted a second layer of colocation and cloud. By the late 2010s the Amsterdam metropolitan area was one of the “FLAP-D” markets with Frankfurt, London, Paris and Dublin that account for most of Europe’s colocation capacity, and the Dutch Data Center Association could claim the country was Europe’s number one data-centre nation per capita.

The hyperscalers came for different reasons. Microsoft chose the Wieringermeer polder at Middenmeer in North Holland for a campus that opened in 2016 because land was cheap, the grid connection to the Noordoostpolder’s high-voltage lines was available, and large consumers paid favourable rates. Google chose Eemshaven in Groningen, announcing a €600 million investment in 2014 and opening in December 2016, for the same reasons plus the landing point of transatlantic cables and the proximity of the Groningen gas-fired power station. Both sites were sold to residents as job creators in lagging regions, which is why the political reaction, when it came, started elsewhere.

Why did Meta’s Zeewolde campus become a national controversy?

Because it combined every objection to hyperscale in one place: farmland, water, subsidised electricity and secrecy. In 2021 the municipality of Zeewolde in Flevoland, a polder town of 23,000, negotiated with a company called Polder Networks that turned out to be Meta, then Facebook, for a 166-hectare campus using up to 200 megawatts, the largest in the Netherlands. The council approved the zoning plan in December 2021 on the promise of 400 jobs and a contribution to the local economy. National opposition was immediate: the campus would use renewable power equivalent to a city while the country was struggling to meet its own climate targets, it would occupy prime agricultural land, and the negotiations had been conducted under non-disclosure agreements.

The decisive blocker was the Senate. Part of the site belonged to the state’s land agency, and in early 2022 the upper house passed a motion against selling it, while the new Rutte IV cabinet announced a nine-month moratorium on hyperscale permits pending national rules. Meta put the project on hold in March 2022 and formally withdrew on 1 July 2022, saying the Netherlands was not a good match for its needs. In September 2023 a court struck down the zoning plan altogether. The company moved its European expansion to Spain and Denmark, a reminder that the hyperscalers have alternatives and that the Spanish data-centre boom is partly a Dutch export.

The Zeewolde episode changed the politics of digital infrastructure. Where Microsoft and Google had been welcomed, every subsequent project was scrutinised for energy, water and land use, and the Dutch public learned that a hyperscale campus can consume as much electricity as a city of 200,000 households without employing more than a few hundred people.

What do the moratoria and the hyperscale rules actually say?

There are three layers, and they are often confused. The first is municipal: in July 2019 Amsterdam and Haarlemmermeer, the municipality containing Schiphol, announced a one-year halt on new data centres, then adopted policies in 2020 that limited growth to about 670 megawatts of new capacity in Amsterdam to 2030 and confined centres to designated business parks with waste-heat and efficiency requirements. Amsterdam’s 2020 policy effectively banned new centres within the city except at Science Park and Amstel III.

The second is national: the February 2022 moratorium on hyperscale permits was followed in June 2024 by rules under the Environment Act that define a hyperscale centre as one of 10 hectares or more or 70 megawatts or more, and permit new ones only in two municipalities, Hollands Kroon in North Holland (where Middenmeer lies) and Het Hogeland in Groningen (where Eemshaven lies), and only with provincial agreement. Everything smaller is left to provinces and municipalities. That is why Google and Microsoft can keep expanding in the north while Meta could not build in Flevoland.

The third is Amsterdam’s 2025 moratorium, which is about electricity rather than planning. With the regional grid operator Liander and the national operator TenneT reporting no capacity for new large connections until substations are built around 2035, the city halted new data-centre developments and extensions in 2025. Projects already permitted, including Equinix’s Zuidoost campus and the Microsoft-leased towers in the western port, proceed under old approvals; the province of North Holland said in January 2026 that the three 85-metre Microsoft towers did not meet the hyperscale definition because they were legally separate buildings, each below the threshold, a ruling critics called a loophole.

How much electricity do Dutch data centres really use?

About 5 per cent of the national total, and the share is rising fast. CBS reported in December 2025 that data centres whose main activity is data storage used about 5,100 gigawatt-hours in 2024, equivalent to almost 2 million homes and 4.6 per cent of Dutch electricity consumption of roughly 116 TWh. Consumption has nearly doubled in five years and risen 37 per cent since 2021. Around 45 large centres each using more than 10 GWh account for most of it; their number has barely changed, but their combined use nearly quadrupled in ten years, from about 1,300 GWh to over 4,700 GWh, as facilities grew denser. CBS’s count excludes in-house centres run by banks, hospitals and universities, so the true figure is higher.

The transparency fight of 2026 revealed how concentrated the load is. Under the EU Energy Efficiency Directive, in force since 2024, centres above 500 kilowatts must report energy and water use to the Netherlands Enterprise Agency (RVO). In July 2026 RVO’s first published data, analysed by NRC, showed that Microsoft’s Middenmeer campus alone used 1.17 TWh in 2025, over 1 per cent of all Dutch electricity. Microsoft, the first American hyperscaler to disclose fully, says the power is matched with renewables. Google, with two large Dutch sites, did not publish figures; Stratix consultant Hendrik Rood estimated that Google’s Eemshaven campus, with nearly twice the floor area of Middenmeer, uses even more. Equinix and EdgeConneX, both building fast around Amsterdam, also withheld data. A Trouw and Lighthouse Reports investigation in September 2026 found RVO’s register listed only 104 centres against the industry association’s 186, and that public data existed for roughly a quarter of large facilities.

Water is a smaller but politically potent issue. Data centres use roughly 0.1 per cent of Dutch tap water, but Equinix’s Zuidoost application requests 274 million litres a year in its first phase rising to 1.1 billion litres when complete, and the summer droughts of 2025 and 2026 sharpened the debate. TenneT expects data centres to account for 10 to 15 per cent of Dutch electricity by 2030, and North Holland alone expects 92 data centres by 2030 on current applications.

Why does grid congestion now decide every project?

Because the Netherlands has run out of transmission and distribution capacity in the regions where data centres, housing and industry all want to grow. By October 2025 more than 14,000 businesses and about 7,300 households were on waiting lists for new or heavier connections; the grid operators’ association reported in September 2026 that there was no capacity for nearly half of the 600,000 home connections requested over three years; and in April 2026 the operators stopped issuing new connections in Utrecht province for six months, placing gas generators around the city as an emergency measure in July. The causes are the electrification of heating and transport, the surge in solar and wind feeding in, and a decade of under-investment in substations, as explained in TenneT and Dutch grid congestion.

Data centres are both victims and villains in this story. They are victims because a hyperscale campus needs a dedicated high-voltage connection that TenneT cannot deliver before the mid-2030s, which is why Equinix’s Amsterdam-Zuidoost campus, permitted on 6 July 2026, will build only one of its four 60-metre towers now and defer the rest until TenneT substations arrive around 2036. The full campus needs an 80-megawatt connection and about 779 million kWh a year, nearly the 869 million kWh used by all Amsterdam households in 2024; Equinix is building its own link to the high-voltage grid and will use only about half of the Liander capacity it reserved years ago. They are villains, in the eyes of residents’ groups such as Stop Datacenter Zuidoost, because capacity reserved by data centres is capacity unavailable for the 5,500 to 8,000 homes planned on the same Amstel III business park.

The municipality’s position shows how constrained local government is. Alderman Alexander Scholtes’ office said the agreements were made long ago and that withdrawing the permit would expose the city to large damage claims. Equinix Benelux director Michiel Eielts called building one tower a compromise, offered the campus’s residual heat free to a district-heating network and offered land and ground-floor space for community use, and argued that every home needs the internet. More than 500 people joined the campaign against the project in August 2026, and Extinction Rebellion and Geef Tegengas demonstrated against Microsoft’s Sloterdijk towers the same summer.

What is happening in Groningen and North Holland in 2025 and 2026?

The north is where the hyperscalers are allowed to grow, and they are growing. Google, which first invested €600 million at Eemshaven in 2014, opened a second Dutch centre at Middenmeer in 2020, broke ground in 2024 on a third at Winschoten with another €600 million, and on a fourth at Groningen’s Westpoort business park with more than €600 million, and opened Winschoten in November 2025. The company says its Dutch centres added about €1.7 billion a year to GDP between 2017 and 2022, that it spent €45 million on 28 kilometres of new water pipelines and purification in Groningen, and that it has matched its electricity use with renewable purchases since 2017. Expansions at Eemshaven and Middenmeer are planned, which means the Google and Microsoft campuses will be the main source of growth in national data-centre load for the rest of the decade.

The Wieringermeer polder around Middenmeer has become the country’s hyperscale district: ten server farms already stand there and six more were under construction in early 2026, and Microsoft plans to expand from two new halls to six across the A7 from its original site. The province of North Holland supports the growth under the 2024 rules, while the municipality of Hollands Kroon has at times resisted, in particular over the diesel back-up generators and the sale of farmland. The underlying bargain is that the north trades land and grid capacity for investment and a few hundred jobs each, a bargain whose other side is examined in the Groningen gas field closure.

Less noticed is the Flevoland case. Equinix obtained permission in 2021 for a 150-megawatt centre at Flevokust Haven in Lelystad after councillors were told it would use roughly the energy of 3,000 to 5,000 households; in February 2026 Nu.nl reported that a 150-megawatt site would in fact exceed the consumption of every household in Lelystad, with one expert estimating 200,000 households and another up to 500,000 at full capacity. The council said the zoning plan met the norms of 2021. The gap between what councils are told and what a megawatt means has become a recurring theme.

What does the moratorium cost the Dutch economy?

Potentially billions, according to the bank that studied it. ING analyst Samantha Reilly concluded in October 2025 that with Amsterdam’s grid at capacity and no new data centres able to connect until about 2035, the sector would see only marginal expansion, and that jobs, investment and technical knowledge in cloud, fintech and AI could shift abroad. ING counted more than 200 Dutch data centres with over half in the Amsterdam region, noted that the number of facilities fell from 198 in 2018 to 191 in 2024 while floor space rose from 267,000 to 393,000 square metres, and put the sector’s electricity share at 3.3 per cent and its water share at 0.08 per cent. The bank urged the government to tie new capacity to offshore wind and district heating rather than to block it.

The industry’s own case rests on what the data centres enable: the Dutch Data Center Association estimates a direct GDP contribution of €1.5 billion, more than 10,000 direct and indirect jobs, and a digital economy worth €460 billion, about 60 per cent of GDP, that depends on local infrastructure. The counter-argument, made by Rick Pijpers of the Dutch Sovereign Data Centre Cooperative, is that almost all new capacity is going to American hyperscalers, leaving little grid room for Dutch providers, and that the country is hosting other people’s clouds at the expense of its own housing. The sovereignty theme is gaining weight: in 2026 Eurofiber agreed to host a sustainable AI factory for the national research network SURF, and the Dutch government’s broader digital-autonomy debate, including the Nexperia seizure, is covered in the Nexperia story.

New forms of location are being explored. In June 2026 Vattenfall and the Amsterdam start-up Project Enki announced a study of offshore data centres connected directly to wind farms, using surplus power that is otherwise curtailed and seawater for cooling, an idea that would bypass the onshore grid entirely. It is early-stage, and the company would not say whether sites would be in Dutch waters, but it shows where the constraint is pushing innovation, alongside the North Sea wind auctions that would supply it.

How does the Netherlands compare with Ireland, Germany and the Nordics?

The Dutch case is the most constrained of the big European markets, but not the only one. Ireland, where data centres consumed about 21 per cent of electricity in 2023, imposed a de facto moratorium on new Dublin connections until 2028 and is now requiring on-site generation; Frankfurt, Europe’s largest market, is running into the same substation limits and has introduced an energy-efficiency law with waste-heat obligations; and the Nordic countries, with cheap hydro and cool climates, are the destination for the capacity the FLAP-D markets cannot absorb, which is where Dutch firms such as ALARA are winning construction orders.

What distinguishes the Netherlands is the collision with housing. No other European country has a 400,000-home shortage, a legally binding nitrogen regime and a grid moratorium in the same cities where the data centres want to build, which is why Amsterdam’s choice between 8,000 homes and four server towers at Amstel III is the sharpest version of a continental dilemma. The housing side of that trade-off is told in the Dutch housing shortage story, and the contractor side in BAM and VolkerWessels after the mega-project losses, since the same builders now compete for substations and data halls.

What can founders and investors learn from the Dutch data-centre boom?

The first lesson is that infrastructure advantages are temporary unless the inputs are renewed. AMS-IX, fibre and a stable grid made the Netherlands Europe’s cloud hub in a decade; failing to build substations at the same pace cost it the next decade. Businesses that depend on a shared resource should model the resource’s growth, not just their own.

The second is that social licence is a precondition, not a public-relations task. Meta lost Zeewolde because it negotiated in secret, promised jobs that could not justify the land and power, and had no local constituency when the Senate intervened. Microsoft kept Middenmeer, despite using 1 per cent of the country’s electricity, partly because it disclosed first and matched its load with renewables. Google’s €45 million water pipeline in Groningen is the price of staying welcome.

The third is that the next data-centre fortunes will be made in flexibility, heat and sovereignty rather than in square metres. The projects that proceed in 2026 all offer something to the grid or the neighbourhood: Equinix’s free waste heat, Microsoft’s prefabricated substations built by BAM, Vattenfall’s offshore concept, Eurofiber’s national AI facility. A Dutch founder’s opportunity is in the layer between the hyperscaler and the grid operator, which is the same place the Dutch scale-up ecosystem found its earlier winners.
