In May 2025, France launched its national resilience plan for rare earths and permanent magnets — a strategic move that has direct implications for AI infrastructure supply chains that most data center analysts have not yet connected to their models.
WHY THIS MATTERS FOR AI INFRASTRUCTURE
Permanent magnets made from rare earth elements are essential components in the generators and motors that power the electrical infrastructure supporting AI data centers. They are present in:
- Wind turbines generating renewable electricity for data centers
- Electric motors in cooling systems
- Certain transformer designs using amorphous metal cores
- Backup power systems

WHAT THE FRENCH PLAN ACTUALLY DOES
The plan has three practical components relevant to infrastructure procurement teams:
Mandatory supply diversification
The offshore wind sector — a key source of renewable electricity for data centers — will be required to source less than 50% of permanent magnets from any single country. This is a direct response to Chinese export restriction risks and will reshape European wind energy supply chains by 2027.
Industrial projects in France
Three specific projects are being developed at Lacq (Pyrénées-Atlantiques), La Rochelle and Grenoble to rebuild French rare earth processing and magnet manufacturing capacity. These projects are partially funded through France 2030 (approximately €330 million in public support for 40 projects).
Formal diversification plans required
Certain companies will be legally required to formalise supply diversification plans for rare earth and magnet inputs. This creates a compliance obligation that procurement and sustainability teams need to prepare for.
THE CHINA RISK SCENARIO
China has already demonstrated willingness to use critical mineral exports as geopolitical leverage. Gallium and germanium export controls were introduced in 2023. Rare earth export restrictions — which would directly affect permanent magnet supply — have been threatened and partially implemented.
For AI infrastructure developers, the scenario to model is a significant restriction on Chinese rare earth exports occurring within a 2–3 year window. This would affect wind turbine delivery timelines (relevant for renewable-powered data centers) and could affect transformer and electrical equipment production if magnet supply tightens.
WHAT PROCUREMENT TEAMS SHOULD DO NOW
- Map rare earth content in your electrical equipment supply chain — where are the magnets in your transformers, cooling motors and backup systems?
- Ask equipment suppliers about their rare earth sourcing — Chinese-origin versus diversified
- Monitor French and EU rare earth policy development — compliance obligations are coming
- Consider the French industrial projects at Lacq, La Rochelle and Grenoble as potential future supply chain partners
