Lucy Electric launches UK’s first non-SF6 Ring Main Unit of its kind, powering the transition to sustainable energy networks

Lucy Electric, a UK headquartered international leader in power distribution solutions, has launched the UK’s first Ring Main Unit (RMU) for medium voltage networks using synthetic air, paving the way for grid operators to reduce the emissions of running infrastructure as part of delivering Net Zero ambitions.

EcoTec, which has been launched at the company’s Technology Day at Silverstone, uses a nitrogen and oxygen blend instead of the SF6-gas currently used to insulate critical electrical network equipment. Although the use of such gases is handled in a highly controlled way, a ban on their use in new and replacement switchgear is expected to be implemented in the UK following an EU ban in 2026. Lucy Electric is the first company to bring switchgear to market that meets the specifications of UK network operators, providing companies the ability to install the improved equipment ahead of the ban coming into force.

The launch follows years of feasibility and close working with customers to inform the requirements of this key part of the medium voltage network. The focus has been on cost effectiveness for long-term network planning and emissions reduction. EcoTec is also designed with ease of installation and cost efficiencies in mind by fitting within the same substation housing space as current switchgear and even aligns with existing concrete slab fixings, further reducing emissions of replacement.

Martin Sweeney, Global Head of Product Management at Lucy Electric said:

“Alongside our customers, Lucy Electric is focused on meeting net zero commitments, and EcoTec is specifically designed to reduce the emissions of UK network operators in an efficient and cost-effective way. We have listened extensively to customer feedback to optimise the design of our switchgear such as embedding the control unit and the smart solutions, including remote control available as standard.

“Lucy Electric has a long heritage as a 200-year-old British engineering business that has been supplying the UK electricity networks for over a century. The UK is Lucy Electric’s second biggest market, and we are proud to bring the first Ring Main Unit of its kind designed and developed in the UK to meet the specification here, at what is a critical stage of efforts to deliver Net Zero.”

Triconnex, one of the largest independent multi-utility companies in the UK is a partner for Lucy Electric in switchgear installations. Ricky Clark, Procurement Manager at Triconnex, said:

“EcoTec will help us meet our targets for emissions reductions in the long-term as well as supporting our continued growth as a key partner for the UK efforts to decarbonise. We are delighted to work with our long-term supply chain partner Lucy Electric to enable the transition to greener energy networks. Their cutting-edge solutions and reliable infrastructure play a pivotal role in our operations. Moreover, the wealth of knowledge held by Lucy Electric’s staff is invaluable to our success.”

EcoTec has been designed and developed in the UK for the UK market and comes ahead of the EU F-Gas regulations effective 1st January 2026 which will ban the use of SF6 for up to 24kV and the likely implementation of this by Defra in the UK. The technology will also be adapted for deployment to international markets in the Middle East, Asia, Africa and Australia as a fantastic example of a UK export from British R&D.
