Most Dutch Data Centers Refuse to Disclose Energy and Water Use

2026-09-30 data

Amsterdam, Wednesday, 30 September 2026.
Despite legal mandates, three-quarters of Dutch data centers withhold their environmental data, hiding massive consumption levels like Microsoft’s single facility consuming one percent of national electricity.

An Ocean of Silence in Europe’s Digital Heartland

The rapid expansion of artificial intelligence (AI) and cloud computing has triggered an unprecedented demand for data infrastructure, but the actual environmental cost remains obscured behind what researchers describe as a European “wall of silence” [2][5]. On September 29, 2026, the international investigative consortium Lighthouse Reports—collaborating with Dutch newspaper Trouw and other European media outlets—filed an official complaint with the European Commission [3]. This legal escalation followed a year-long investigation using freedom of information laws across all 27 EU member states, which yielded virtually no usable data on energy and water consumption [1][3][4]. The probe revealed that less than 25% of large Dutch data centers publicly disclose their electricity and drinking water usage, despite clear European regulatory mandates [1].

The Regulatory Gap and the Missing Registrations

The European Energy Efficiency Directive (EED), which came into force in September 2023, legally obligates data centers with an IT capacity of 500 kilowatts (kW) or more to report their energy and water footprint [1][7]. However, compliance is severely lagging. By the end of 2025, the Dutch Datacenter Association (DDA) identified 186 commercial data centers in the Netherlands meeting this 500 kW threshold [1]. Yet, the Netherlands Enterprise Agency (RVO), which collects this data on behalf of the EU, possesses records for only 104 facilities [1][4]. This leaves a massive discrepancy of 82 unregistered centers [1][4]. The RVO’s current database is highly fragmented, containing electricity usage data for just 44 facilities and water consumption records for only 47 [1].

A Strained National Grid and Massive Tech Footprints

The lack of transparency comes at a time of severe strain on the Dutch power grid. Grid capacity shortages have triggered severe connection delays for Dutch businesses since May 18, 2026, and affected public institutions as of September 9, 2026 [1]. Notably, the National Institute for Public Health and the Environment (RIVM) was forced to delay relocating to its new headquarters due to grid congestion [1]. Furthermore, as of September 18, 2026, nearly 50% of newly built homes in the Netherlands faced power grid connection delays [1]. Despite these constraints, Statistics Netherlands (CBS) reports that in 2024, data centers consumed 5.1 billion kilowatt-hours (kWh), representing 4.6% of total national electricity consumption [1]. This represents a near doubling over five years [1][4]. Looking ahead, grid operator TenneT projects that data center electricity demand will surge to between 10% and 15% of the national total by 2030 [1][4].

Corporate Giants and the Battle for Public Data

The massive scale of individual facilities highlights why public disclosure is so critical. Data released on July 14, 2026, confirmed that Microsoft’s largest data center in Middenmeer consumes a staggering 1% of the total national electricity supply [1][3]. While Microsoft has disclosed this figure, Google, which operates two massive data centers in the Netherlands, refuses to publish any environmental consumption data [1][4]. Meanwhile, Equinix is constructing a new facility in Amsterdam that is projected to consume 1.1 billion liters of drinking water annually, raising intense scrutiny in the province of Noord-Holland [5]. To bypass grid limitations, global tech companies are increasingly seeking alternative energy sources; for example, research published on September 22, 2026, revealed that Amazon plans to construct gas-fired power plants for its data centers with a total capacity equivalent to the entire grid capacity currently in the Netherlands [3].

Forcing Transparency Through the Aarhus Convention

To break this gridlock, Lighthouse Reports and its media partners are initiating a legal procedure under the Aarhus Convention [2][5][7]. This international treaty, signed by all EU member states, guarantees citizens the right to access environmental information [2][4]. The legal action aims to challenge the European Commission’s 2024 decision to classify data center operational metrics as “trade secrets”—a designation that think-tank Leitmotiv co-founder Christiaan van Veen calls “unfathomable” [3][7]. While the European Commission announced plans on September 21, 2026, to introduce mandatory sustainability labels for data centers, the implementation timeline remains uncertain [3]. In the Netherlands, the DDA claims that reporting instructions were updated in 2026 to align with the EED, with more comprehensive data expected later in the year [7].
