ScoreMyDataCenter Independent observatory 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
62%
of the fleet is connected to an already-saturated substation.
The fleet is here. The grid already lacks headroom.
You are looking at
Europe
The fleet was built on land already taken — but connection queues keep growing.
62%
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 · Grid hosting capacity — Caparéseau (RTE) (France) · n = 703 · 20 sites with no published value — excluded and counted apart 6 of 18 countries
35%
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 · WRI Aqueduct 4.0 · VigiEau (France) · n = 1,398 · 8 sites with no published value — excluded and counted apart 17 of 18 countries
93%
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.
Corine Land Cover (EEA) · Land use — IGN API Carto (France) · n = 1,414 18 countries
63%
of sites face a high or critical grid-connection queue.
Grid operators' connection queues · Connection queues — Caparéseau (RTE) (France) · n = 589 4 of 18 countries
21%
of sites border a protected natural area, within one kilometre.
Protected areas — EEA CDDA / Natura 2000 · Natura 2000 & ZNIEFF — INPN / IGN (France) · n = 1,414 18 countries
6%
of sites neighbour a high-hazard industrial site, within 2 km.
National registers of high-hazard industrial sites · Classified installations — Géorisques (France) · n = 834 9 of 18 countries
Operators disclose their capacity — but the heat is wasted almost everywhere.
18%
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 = 1,414 18 countries
7%
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.
Operators' public disclosures · n = 545 · 509 sites with no published value — excluded and counted apart 2 of 18 countries
<1%
of sites declare recovering their waste heat (heat networks, nearby facilities) — the first lever of a good project.
What it meansBetween intention and implementation, the gap remains huge.
Operators' public disclosures · n = 394 · 391 sites with no published value — excluded and counted apart France only
The tracked fleet is already running — but what's coming doesn't always state its capacity.
96%
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.
ScoreMyDataCenter corpus — project status · n = 1,414 18 countries
2,942 MW
announced across projects not yet in service (59 projects — 39 do not disclose their capacity).
ScoreMyDataCenter corpus — announced & permitting projects · n = 59 4 of 18 countries
52
projects under citizen opposition or moratorium — recorded and sourced, never graded on that basis.
What it meansSourced facts, never a grade — context.
Watch layer — sourced facts, never a grade · n = 52 10 of 18 countries
The territory's constraints, ranked by the share of sites concerned — a descriptive ranking, never a grade.
93%
of sites do not publish their real efficiency.
62%
of sites near a saturated substation.
35%
of sites in high water-stress areas.
21%
of sites within 1 km of a protected natural area.
6%
of sites within 2 km of a high-hazard industrial site.
recomputed per perimeter: share of sites concerned by each constraint
A mechanical, published selection — the most common profile, the most constrained, the best documented. Real situations behind the aggregates.
