SP Energy Networks energises the UK’s first non-SF6 switchgear from Lucy Electric

1st Installed in the UK

Leading UK electricity network operator, SP Energy Networks (SPEN), has energised the country’s first non-sulphur hexafluoride (SF6) switchgear from Lucy Electric, marking a significant milestone in the UK’s grid decarbonisation journey. The innovative Sabre EcoTec Ring Main Unit (RMU), which uses synthetic air instead of the SF6 greenhouse gas currently used to insulate critical electrical network equipment, has been installed and energised at a substation in SPEN’s mid-Cheshire district. The product ensures lower emissions from network operations, addressing the challenge of a gap in available products ahead of the anticipated UK ban on SF6 in 2026. The installation is a vital step on SPEN’s journey to develop what it is calling ‘truly sustainable substations’, which will be environmentally sustainable at every stage of development – from design through construction to operation.

33 Tonnes of CO 2 per switchgear unit saved

12kV Meets EU F-Gas regulations effective 1st January 2026, banning the use of SF6 for up to 24kV
