TL;DR
Police said 218 people were arrested on suspicion of trespassing after protesters entered a data center construction site in Amsterdam on November 6; all have since been released. The action formed part of a European campaign against large data centers, as governments and communities weigh growing demand for computing against electricity, water and grid pressures.
Police in Amsterdam said 218 people were arrested on suspicion of trespassing after protesters entered a data center construction site leased to Microsoft on November 6; all have since been released. The action in the city’s Westpoort port district was part of a wider European campaign opposing large data centers, whose expanding electricity and grid needs are drawing scrutiny as demand for AI computing grows.
The protest began after a climate group, Fossil Free Netherlands, planned a demonstration outside the site at an agreed location. Dutch police said officers stopped some demonstrators carrying an angle grinder and climbing equipment. According to police accounts reported by Dutch outlets, calls to hand over the items were followed by resistance and confrontations. Around midday, members of the collective Geef Tegengas entered the site after a fence was cut, climbed a crane and the building roof, and displayed banners. Police later gave protesters time to leave before riot police cleared the remaining people. One officer was slightly injured.
The final count was 218 arrests, according to a police spokesperson quoted by the Dutch news agency ANP on November 7. The arrests were on suspicion of trespassing, and all those detained have been released. The site owner has filed a complaint alleging trespassing, vandalism and burglary; those allegations have not been decided by a court. Estimates of the crowd differ: a Reuters witness saw about 100 people on the site, while organisers and campaigners gave higher figures.
The site is being developed by British company Pure DC, not Microsoft, which is due to lease it. Pure DC says its AMS01 project will comprise three towers, each 85 metres high, with a combined 78 megawatts of data-hall capacity and a dedicated substation. The company puts the investment at more than €1 billion. It says the facility is designed to use non-potable water from the port for cooling and to allow waste-heat export, though arrangements for heat exchange with Vattenfall are still being planned.

Europe’s Grid Faces New Demand
The protest reflects a conflict between Europe’s push for computing capacity and local concerns about the resources and infrastructure needed to run it. The European Commission, citing the International Energy Agency, estimates that data centers used 70 terawatt-hours of electricity in the EU in 2024, with consumption projected to reach 115 TWh by 2030. That is a forecast, not a confirmed future outcome, but it points to the scale of expected demand.
Grid capacity is central to the dispute because data centers need large, steady power supplies, while cities also need connections for homes and other services. Amsterdam says it has allowed no new large data centers since June 2025. In Ireland, data centers accounted for 22% of metered electricity use in 2024, according to the supplied source material. These figures do not establish that data centers alone cause higher household bills or delays to housing connections; those effects depend on local energy systems and investment decisions. They help explain why communities and campaigners are asking who bears the costs.
There are also economic and strategic stakes. Companies and governments view local computing infrastructure as a way to support digital services and AI capacity. Microsoft has said it plans to increase its data center capacity in Europe by 40%. Opponents counter that large facilities can bring relatively few permanent jobs compared with their energy and land requirements. Pure DC says AMS01 would support more than 80 permanent jobs after construction and generate about €4 million a year in city taxes and revenues. Those are company estimates, not independently verified outcomes.

From Local Dispute to European Campaign
The Amsterdam action took place amid coordinated activity organized by the coalition Stop Dirty Data Centres, which calls for a moratorium on large data centers. Accounts differ on the campaign’s 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, including talks and walks as well as protests, so that figure should not be read as a count of site occupations.
The Amsterdam project has faced opposition before. Business Insider reported that the same group had blocked the site in June 2026. The current protest drew attention not just to the construction project but to broader objections listed by the coalition: electricity demand, grid connections, water use during hot weather, climate targets, local employment and surveillance concerns. The precise local effects of the AMS01 project on power prices, housing connections or water availability have not been established in the material available.
Microsoft is the proposed tenant, while Pure DC is the developer. That distinction matters when assigning responsibility for construction, design and operation. Pure DC says the project’s power usage effectiveness is designed to be below 1.18, compared with a Dutch target of 1.2. These are project design claims; the facility has not yet demonstrated operating performance. The company also says its cooling supply will be non-potable port water, rather than drinking water.
““We understand that people feel strongly about the project, and we respect their right to express those views peacefully. However, we do not condone any actions that are unlawful or that put people’s safety at risk.””
— Microsoft
Project Impacts Still Need Evidence
Several points remain unresolved. The exact number of people who entered the site is disputed, with estimates ranging from around 100 to several hundred. Police say 218 people were arrested on suspicion of trespassing and that all have been released, but the site owner’s complaints of trespassing, vandalism and burglary remain allegations; no court finding is described in the source material.
The longer-term effects of AMS01 on local electricity supply, household costs, water resources and housing connections are also unclear. Pure DC’s figures on jobs, tax revenues, water and energy efficiency are company projections or design claims, not verified operating results. The planned waste-heat exchange with Vattenfall has not yet been finalized. It is also not clear what legal or planning steps, if any, will follow the protest or whether the project schedule will change.
Construction and City Oversight
Police and the site owner may pursue the trespassing complaint, but the source material does not give a timetable for any investigation or court proceedings. The immediate next steps are also likely to depend on whether the developer, local authorities and campaigners hold talks about the project and its effects.
Pure DC has said construction is expected to reach a peak workforce of 1,100 in 2027, followed by more than 80 permanent jobs. Those are company plans, not confirmation that the schedule will proceed unchanged. The proposed heat-exchange arrangement remains in development, and the facility’s actual resource use can be assessed only once it is operating. Further protest activity and decisions about permitting or local infrastructure could clarify whether the Amsterdam dispute changes the project or remains part of a broader debate over data center growth.
