By 2027, standards applicable to HV switchgear cells will evolve, as part of the progressive phase-out of SF₆ and the tightening of European environmental requirements. This regulatory change will mechanically lead to a transformation in the product ranges available on the market.
For large companies, the service sector, local authorities, hospitals, public services, as well as shopping centres and supermarkets, this deadline represents a technical, financial and strategic challenge that deserves a factual and nuanced analysis.
Next-generation equipment… rigorously regulated
Contrary to some misconceptions, the introduction of new HV cells on the French market is neither rushed nor without guarantees. All new equipment is tested in certified laboratories, then trialled in the field by reference players — first and foremost Enedis — before obtaining final approval for use.
Moreover, several manufacturers choose to build on proven mechanical processes, such as the rotary mechanism, successfully used for over twenty years. Future generations are therefore not starting from scratch, but are built on a widely mastered technological base.
Reliability thus remains a central criterion in the development of new equipment, even in a context of environmental innovation.
A probable price increase, but one to put in perspective
The transition to SF₆-free technologies represents a major industrial challenge, requiring R&D and production investments estimated at several tens of millions of euros. It is logical that these investments will, in the short term, have an impact on prices.
However, recent sector history invites a relative view:
- In the early 2000s, HV cells cost up to twice as much as they did in 2008
- The gradual price decreases observed since then are explained by standard industrial amortisation, volume industrialisation and technological maturity
Anticipating: a strategic option, not a dogmatic obligation
Renovating or modernising an HV substation before 2027 can offer real advantages: better budget visibility, planning work without regulatory calendar constraints, and use of well-known, fully documented solutions.
However, this anticipation should not be seen as circumventing European regulations. The challenge is not to “do it before so you don’t have to do it after”, but to choose the right moment, based on:
- The actual condition of the installations
- Operational constraints
- Service continuity requirements
- The environmental commitments of each organisation
Conclusion
The 2027 deadline should neither provoke fear nor be minimised. Above all, it calls for an informed decision based on solid technical, economic and regulatory data.
Anticipating may be relevant in some cases. Accompanying the transition to new generations will be equally relevant in others. The best strategy remains one that combines operational safety, environmental responsibility and cost control — without alarmism, but without inaction either.
