Data centres, France

The electricity of data centres installed in France on dedicated sites, and RTE's projections.

Selected reference: In 2024, source Projet Celsius.
The electricity range runs from 4 TWh to 5 TWh, within the scope of this entry.
This total covers all uses of data centres; it does not measure AI's share alone.
Out of scope: companies' internal server rooms, devices and telecommunication networks.

Origin of the value

In 2035, consumption would be 5 to 7 times that of 2024, depending on the scenario.

Published values

5 figures for the same quantity, each in its own scope.

Electricity

Green: same scope as the selected value (measured in dark, estimated or published in light). Grey: other scope. Empty circle: check by the database or discarded figure. Logarithmic scale.

Water

Published by its sources, not yet selected by the database: see the convention on water in Methodology and conventions.

Source	Date	Water	What the figure measures	Scope	Status
Arcep ↗Intelligence artificielle et environnement	May 2026	6,500 Mm³	France, 2024, water withdrawn or consumed by the data centres of the operators surveyed by Arcep · The survey does not say whether this is water withdrawal or consumption, nor whether the water used to produce electricity is included	other scope	published

The published figures do not all count the same scope; the scope of each figure is written next to it. Why do the estimates diverge?
