Phasing out SF6: Enedis extends its agreement with Schneider Electric to the secondary grid
Signed on 27 May 2026 for four years, the agreement anticipates the European F-Gas regulation, which has banned SF6 below 24 kV since 1 January 2026.
On 27 May 2026, Enedis and Schneider Electric announced the signature of a new framework agreement aimed at modernising public distribution grid equipment and reducing its environmental footprint.
Concluded for a term of four years, extendable to six, this agreement anticipates the European F-Gas regulation, which has banned the use of SF6 gas in new electrical installations rated at 24 kV or below since 1 January 2026.
SF6, or sulphur hexafluoride, has long been used as an insulator in electrical switchgear for its excellent dielectric properties. Its global warming potential, several thousand times that of CO2, nevertheless makes it a priority target of climate regulation.
The agreement supplements an initial framework contract concluded in 2025 for the roll-out of the MCSet-NS500V switchgear on primary networks. It provides for the introduction of the RM AirSeT switchgear on secondary networks, with first deliveries expected during 2026.
Enedis thereby gives itself the capacity to deploy SF6-free solutions across the entire public distribution grid it operates, securing its regulatory compliance and the durability of its investments.
