TL;DR
Police said 218 people were arrested after protesters entered a data center construction site in Amsterdam on November 6; all had been released by the next day. The action was part of a wider European campaign calling for limits on large data centers, amid disputes over their electricity and water use, local benefits and Europe’s need for computing capacity, as explored in local votes on data centers.
Police said 218 people were arrested after protesters entered a data center construction site in Amsterdam on Friday, November 6, and all had been released by Saturday. The site is being developed by Pure DC for Microsoft; the protest formed part of a wider European campaign challenging large data centers over electricity demand, water use and their local costs, issues also examined in the financing of AI data centers.
The site is in Westpoort, Amsterdam’s port area. Police said a fence was cut open and some protesters climbed a crane and the building roof, lit flares and hung banners opposing AI and Microsoft. Riot police cleared the site after giving those inside time to leave. One officer was slightly injured, according to the source account. The arrests were on suspicion of trespassing; the police spokesperson’s final count, reported by the Dutch news agency ANP, was 218.
A Reuters witness saw about 100 people on the site, while organisers described a larger crowd. Those figures differ and should not be treated as a settled count. The site owner has filed a complaint alleging trespassing, vandalism and burglary. Police also said some people may have carried items taken from the site. These are allegations, and no court ruling is reported.
Developer Pure DC says the project, called AMS01, will consist of three 85-metre towers with 78 megawatts of data hall capacity, at a cost of more than €1 billion. The company says cooling will use non-potable water from the port’s industrial supply and that the design is intended to allow waste-heat export, a feature tied to the broader infrastructure demands of the AI data center boom. A heat-exchange arrangement with Vattenfall is still being planned. Microsoft is the tenant, not the developer.

The dispute over power and local costs
The Amsterdam protest reflects a wider question facing European governments and communities: how quickly to expand computing infrastructure while meeting climate and energy goals and managing pressure on electricity networks. The European Commission, citing the International Energy Agency, puts EU data center electricity consumption at 70 terawatt-hours in 2024 and projects it could reach 115 terawatt-hours by 2030. That forecast describes expected demand, not a guarantee that all planned projects will be built.
Opponents say large facilities can compete with housing and other users for scarce grid connections, contribute to higher bills, use water and bring relatively few long-term jobs. These are campaign concerns, not findings established by the Amsterdam protest itself. Pure DC, by contrast, says the project would generate investment, tax revenue and construction work, and that its cooling system would not draw on drinking water. The project’s actual effects on local bills, water resources and the grid are not established in the source material.
The debate also concerns Europe’s access to computing capacity. Microsoft has promised to increase its European data center capacity by 40%. More facilities could support cloud services and AI applications, while communities and authorities weigh the costs and benefits of hosting them. The competing interests make decisions about permits, grid access and infrastructure planning consequential beyond this single site.

A wider European campaign
The Amsterdam action was linked to Stop Dirty Data Centres, a coalition calling for a moratorium on large data centers. Reports differ on the campaign’s geographic reach: Reuters reported actions in 16 countries, while organisers told the Associated Press and Agence France-Presse that actions took place in 15. The coalition’s website lists 85 events, many of them talks and walks rather than protests at construction sites. These counts describe different accounts and event types, not necessarily the same measure.
Amsterdam has already restricted expansion: the city says it has permitted no new large data centers since June 2025. Elsewhere, the scale of electricity demand is a concern. Data centers accounted for 22% of metered electricity use in Ireland in 2024, according to the figures in the source material. That is an Ireland-specific share for that year; it does not describe the whole of Europe.
The site’s developer, British company Pure DC, says AMS01 would have its own substation, peak construction employment of 1,100 in 2027 and more than 80 permanent jobs. It projects about €4 million a year in city taxes and revenues. Those are company-provided figures and projections. Its claim that the design’s power usage effectiveness will be below 1.18 is also a design claim, not a reported measurement from an operating facility.
““We understand that people feel strongly about the project, and we respect their right to express those views peacefully.””

Unresolved questions at the site
The reported crowd size remains uncertain: a Reuters witness estimated around 100 people on the site, while organisers gave higher figures. The police account confirms 218 arrests and their release, but those facts do not establish whether any individual committed the alleged offences. The site owner’s complaint is not a court finding.
The protest account does not establish the project’s eventual effects on electricity prices, grid access, drinking-water supplies or nearby residents. Pure DC says its cooling would use non-potable industrial water and that waste-heat export is planned, but the heat-exchange arrangement is not yet settled. The company’s projected jobs and revenues are also forecasts, rather than realized outcomes.
The source material reports different totals for campaign actions across Europe and does not provide a single independently verified count of protests. It is also not clear whether the Amsterdam project will proceed on its current schedule or whether the protest will change local planning or permitting decisions.
Permits, construction and police complaints
Police and prosecutors may continue handling the complaints related to the site, but the source material does not report charges or court dates. The fact that all 218 people had been released by November 7 does not determine the outcome of any investigation.
For the development, the next relevant questions are whether construction continues as planned, how the proposed substation and grid connection are handled, and whether Pure DC and Vattenfall agree on a waste-heat exchange. The company has described a peak construction workforce in 2027, but the material does not confirm a construction timetable or whether the project has cleared every relevant approval.
European authorities and local governments will also face continuing decisions about data center growth, electricity demand and limits on new projects. The Amsterdam protest puts those trade-offs in public view, but it does not by itself settle policy or establish the project’s eventual costs and benefits.
Key Questions
Why did protesters enter the Amsterdam site?
The action opposed a large data center planned for the site and formed part of a campaign raising concerns about electricity use, water, climate goals and local benefits. The source material does not establish that every person at the protest shared the same motive.
Who is building the data center?
Pure DC is developing the project, while Microsoft is the tenant. Pure DC describes AMS01 as three towers with 78 megawatts of data hall capacity and an investment exceeding €1 billion.
How many people were arrested, and were they charged?
Police reported that 218 people were arrested on suspicion of trespassing and that all had been released by November 7. The source material does not report charges or a court ruling; the site owner’s allegations of trespassing, vandalism and burglary remain allegations.
What does Pure DC say about water and waste heat?
Pure DC says the site’s cooling system would use non-potable water from the port’s industrial supply and that the design would allow waste-heat export. A heat-exchange arrangement with Vattenfall was still being planned, so the source does not confirm that heat will be supplied to users.
Is there a Europe-wide moratorium on data centers?
No moratorium is reported as having been adopted across Europe. The Stop Dirty Data Centres coalition is calling for one, while Amsterdam has separately said it has permitted no new large data centers since June 2025.
