T&D Europe and ENTSO-E joint proposal for transition times from SF6 to alternative technologies for HV and EHV applications

Joining forces with ENTSO-E, in this paper T&D Europe proposes transition times to shift from SF6 to alternative technologies, covering the wider European HV and EHV energy transmission community. 

Transmission System Operators (ENTSO-E) use sulphur hexafluoride (SF6) gas in numerous high-voltage (HV) and extra-high-voltage (EHV) alternating current (AC) applications, in particular in their Gas Insulated Substations (GIS), compact switchgear assemblies and in circuit breakers, and instruments transformers in their Air Insulated Substations (AIS).

ENTSO-E and T&D Europe are aware of the impact of SF₆ gas emissions on global warming. Accordingly, both associations expressed their commitment to reduce these emissions, as declared in previous position papers on SF6 and SF6 alternative technologies that are in line with the EU carbon neutrality target for 2050.
