Fleet figures

What public data says about data centers, aggregated site by site. Every figure is dated, sourced and recomputable.

The figure of this edition — on the selected territory

55%

of the fleet is connected to an already-saturated substation.

The fleet is here. The grid already lacks headroom.

ⓘ This is not a ranking. It is the photograph of a territory: what it already hosts, what it can still absorb, and what public files actually allow to know.

1. Can you still build here?

The fleet was built on land already taken — but connection queues keep growing.

55%

of the fleet is connected to an already-saturated substation.

What it meansNew grid connections can become longer, costlier or more uncertain.

Grid operators' hosting-capacity registers · n = 134 · 18 sites with no published value — excluded and counted apart Netherlands

15%

of sites sit in a basin under high water stress or water crisis.

What it meansCooling choices become a territorial question, not only a technical one.

WRI Aqueduct 4.0 · n = 151 · 1 site with no published value — excluded and counted apart Netherlands

97%

of the fleet is built on already-artificialized soil — not on farmland or natural land.

What it meansThe fleet grows mostly on already-transformed land — not every new project follows that logic.

66%

of sites face a high or critical grid-connection queue.

5%

of sites border a protected natural area, within one kilometre.

36%

of sites neighbour a high-hazard industrial site, within 2 km.

2. What do we really know about the projects?

Operators disclose their capacity — but almost none proves its performance.

24%

of sites disclose their electrical capacity — the basic figure of any public debate.

What it meansThe basic figure of any public debate is usually available.

Operators' public disclosures · n = 152 Netherlands

22%

of sites publish their real energy efficiency (PUE). Claimed efficiency is never proof — publishing is the first step.

What it meansClaimed efficiency is never proof — publishing is the first step.

3. Where is the fleet heading?

The tracked fleet is already running — but what's coming doesn't always state its capacity.

99%

of the tracked fleet is already operating — we measure what exists, not only what is promised.

What it meansWe measure what exists first, not only what is promised.

4. What weighs most here?

The territory's constraints, ranked by the share of sites concerned — a descriptive ranking, never a grade.

1

Transparency

78%

of sites do not publish their real efficiency.

2

Power grid

55%

of sites near a saturated substation.

3

High-hazard sites

36%

of sites within 2 km of a high-hazard industrial site.

4

Water

15%

of sites in high water-stress areas.

5

Protected areas

5%

of sites within 1 km of a protected natural area.

5. Three projects that tell this territory

A mechanical, published selection — the most common profile, the most constrained, the best documented. Real situations behind the aggregates.

The most common profile

HostSlim — Woerden

Site gradeB
  • Operational · capacity not disclosed
  • Connected to an already-saturated substation
  • On already-artificialized soil

criterion: the territory's modal profile (status, grid, soil, most frequent grade)

The most constrained

Datacenter Arnhem KLW — Arnhem

Site gradeD
  • 4 cumulated territorial constraints
  • Connected to an already-saturated substation
  • Within 1 km of a protected area

criterion: highest cumulated territorial frictions in the perimeter

View the fiche →
The best documented

BIT 2BCD — Ede

Site gradeD
  • Documentary confidence: medium — 51%
  • Operational

criterion: highest documentary-confidence score
