Since the French law on simplifying economic life of 26 May 2026, a large data center can be designated a "project of major national interest" (PINM). Many developers call it a fast track. The status does speed up some steps, but it settles neither the grid connection nor the environmental permits. Here is what to know before building a strategy around it.
DOES YOUR SITUATION LOOK LIKE ONE OF THESE?
1. WHAT IS PINM STATUS?
Article 35 of the law added a paragraph I bis to article L. 300-6-2 of the French Planning Code. It allows the State to designate a data center as a project of major national interest by decree. The Constitutional Council upheld the mechanism in its decision of 21 May 2026.
The law sets no power threshold. It looks at the size of the investment, the installed power and the contribution to competitive national ecosystems. The project must be of particular importance for the digital transition, the ecological transition or national sovereignty. It is a case-by-case decision taken at State level.
2. WHAT THE STATUS CHANGES
The building permit is issued by the prefect, not the mayor (article L. 422-2 of the Planning Code).
Local plans can be adapted faster. A specific procedure, run by the State, brings the local plan into line with the project. A decree of 8 December 2025 designates the competent authority.
Some height rules of the local plan can be set aside (article L. 152-5-3).
3. WHAT IT DOES NOT CHANGE
No overriding public interest recognised in advance. For other PINM projects, this recognition eases protected-species derogations. The Constitutional Council made clear that it does not apply to data centers designated by decree.
No exemption from the zero net land take objective. The provisions that allowed it were struck down on procedural grounds.
Environmental permits stay the same. Classified installations, impact assessment, environmental authorisation: the substantive conditions do not change. The suspension of the Alixan permit in July 2026 is a reminder that a weak file stays fragile, whatever its status. See data center permits in France.
Water can still justify a refusal. The same law allows a data center permit to be refused in an area under structural water stress.
4. WHAT ABOUT THE GRID CONNECTION?
This is the most misunderstood point. PINM status does not, by itself, give a project priority in RTE's queue. The law provides a separate mechanism: for industrial and digital projects with very high power demand, the energy minister can ask RTE to reserve grid capacity. An additional financial contribution may be charged to the project, under principles approved by the energy regulator (CRE).

Developers often think of the status and the capacity reservation as one thing. They are two separate decisions, taken by different bodies. See also RTE's five fast-track sites and our support for an RTE PTF request.
5. HOW TO PREPARE A FILE
Designation is not a formality. It is prepared like an investment case presented to the State:
A permitting file consistent with that connection, on the same scope
Figures on water, waste heat and noise
What the project brings to the area and the country: jobs, sovereignty, uses
Early dialogue with the prefecture, State services and local officials
The last point matters as much as the others. A project that officials and services understand before filing is better defended, and less exposed to legal challenges. The status speeds up a procedure; it does not replace explaining the project.

FREQUENTLY ASKED QUESTIONS
Who decides to designate a data center as PINM?
The State, by decree, case by case. The law sets no power threshold: it looks at the investment, the installed power and the project's importance for the digital transition, the ecological transition or national sovereignty.
Does a PINM data center get priority grid connection from RTE?
Not automatically. The law provides a separate mechanism: the energy minister can ask RTE to reserve capacity for projects with very high power demand, with a possible additional financial contribution.
Does PINM status remove the need for an environmental permit?
No. The substantive permit conditions do not change: classified installations, impact assessment, environmental authorisation where required. Nor does the status give data centers an advance recognition of overriding public interest.
Who issues the permit for a PINM data center?
The prefect, not the mayor. Local plans can also be brought into line through a faster procedure run by the State.
