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
80%
of the fleet is connected to an already-saturated substation.
The fleet is here. The grid already lacks headroom.
You are looking at
France
The fleet was built on land already taken — but it plugged into a grid with no room left.
80%
of the fleet is connected to an already-saturated substation.
What it meansNew grid connections can become longer, costlier or more uncertain.
Grid hosting capacity — Caparéseau (RTE) · n = 405 · 3 sites with no published value — excluded and counted apart France
47%
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 · VigiEau · n = 402 · 6 sites with no published value — excluded and counted apart France
91%
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.
Land use — IGN API Carto · n = 407 · 1 site with no published value — excluded and counted apart France
59%
of sites face a high or critical grid-connection queue.
Connection queues — Caparéseau (RTE) · n = 405 France
36%
of sites border a protected natural area, within one kilometre.
Natura 2000 & ZNIEFF — INPN / IGN · n = 407 France
21%
of sites neighbour a high-hazard industrial site, within 2 km.
Classified installations — Géorisques · n = 406 France
Operators disclose their capacity — but almost none proves its performance.
54%
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 = 408 France
<1%
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 = 408 · 406 sites with no published value — excluded and counted apart France
<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 = 408 · 406 sites with no published value — excluded and counted apart France
The tracked fleet is already running — but what's coming doesn't always state its capacity.
82%
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 = 408 France
6,019 MW
announced across projects not yet in service (72 projects — 47 do not disclose their capacity).
ScoreMyDataCenter corpus — announced & permitting projects · n = 72 France
34
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 = 34 France
The territory's constraints, ranked by the share of sites concerned — a descriptive ranking, never a grade.
100%
of sites do not publish their real efficiency.
80%
of sites near a saturated substation.
47%
of sites in high water-stress areas.
36%
of sites within 1 km of a protected natural area.
21%
of sites within 2 km of a high-hazard industrial site.
recomputed per perimeter: share of sites concerned by each constraint
