Protesters entered a construction site for a data center planned for Microsoft in Amsterdam on Friday, climbing a crane and setting off flares as European campaigners began two days of action against large computing projects. Police moved to clear the site in the city’s Sloterdijk district, the Associated Press reported.

The Nov. 6 protest brought a dispute over electricity, land and the pace of construction to a project whose first permit dates to 2020. Dutch officials acknowledge that the electricity network is congested in many areas. They have also said the Amsterdam project falls outside a national rule restricting the largest facilities. The distinction helps explain how a large data center can move forward while the country tightens rules for new projects.

What happened at the site

Dutch public broadcaster NOS reported that demonstrators cut through a fence and entered the site, while environmental campaigners held a separate demonstration outside. Police said one demonstrator had been detained and an officer was slightly injured, according to the broadcaster. Pro-Palestinian activists were among those protesting. Opposition to the site brought together groups with different concerns, including how technology companies use computing capacity and how much electricity new facilities will need.

Microsoft said it respected peaceful expression and opposed actions that were unlawful or put people at risk. Pure Data Centres, the site owner, asked protesters to leave safely and said it was prepared to discuss their concerns, Reuters reported. The owner plans to invest more than $1 billion, according to that report. Neither company’s statement announced a decision to abandon the project.

Why newer rules did not stop the project

In a parliamentary response, the Dutch government said a regional environmental agency issued the building permit on Amsterdam’s behalf in November 2020, following an application submitted in December 2019. North Holland province issued three environmental permits in July 2025, one for each planned data center tower. At the time of the government’s response, an appeal against the environmental permits was pending.

The Dutch national rules for hyperscale data centers took effect in January 2024 and apply to facilities that exceed 10 hectares of built floor area and have an electrical connection capacity of at least 70 megawatts. The government said the Amsterdam project is below the floor area threshold. It said the land use decision belonged to Amsterdam and North Holland, within their respective responsibilities. The response also said the government did not know what Microsoft would run on the servers. The wider buildout of AI infrastructure provides context for the protest; the record does not establish which workloads will run at this site.

Grid capacity is a local question

Dutch officials said no explicit government decision gave the site priority over housing and that the date of its electricity contract was not public. They assumed the agreements were concluded around the time of the original permit application, before rules for prioritizing scarce grid capacity. Under the framework described in the parliamentary response, housing can receive priority for new requests for power transport capacity; commercial data centers generally do not. That framework does not establish when this project secured capacity or quantify any effect on housing connections.

The International Energy Agency estimated that data centers used about 415 terawatt-hours of electricity in 2024, or 1.5 percent of global consumption, and projected roughly 945 terawatt-hours by 2030 in its base case. The agency notes that facilities often cluster in a small number of locations, so the strain on a particular grid can be much greater than a global share suggests. Those figures put the broader buildout in perspective; they do not measure the Amsterdam project’s power or water use.

The agency also estimates that roughly one in five planned data center projects could face delays if grid constraints are left unresolved. New transmission lines can take four to eight years to build in advanced economies, it says. That timing helps explain why an industrial site with an existing connection or a place in the queue can be valuable to a developer. It also explains why a construction permit and access to enough electricity are separate milestones: a local authority can authorize a building without adding capacity to the network that would serve it.

A European campaign with local decisions

The campaign coalition called for a temporary halt to large data center developments until governments address social and environmental concerns. It listed events for Friday and Saturday in several countries, including a march in Dublin and meetings in Britain. The Amsterdam action showed how that wider campaign is playing out at projects that already have years of permits and investment behind them.

The Dutch government has argued that data centers support the country’s digital infrastructure and competitiveness, while acknowledging limits on how much land and electricity can be made available. For this project, the clearest evidence of any lasting change would come from a decision by the developer, a permitting authority or a court. Friday’s action brought more attention to those decisions, but the reports of police clearing the site did not establish a long-term construction halt.
