SP Energy Networks energises UK’s first non-SF6 switchgear from Lucy Electric
It also cements SPEN’s long-standing partnership with Lucy Electric, which saw the network operator input into the design and product development process for EcoTec, alongside other UK distribution network operators. This collaboration has been key to ensuring the RMU meets SPEN’s current specification and future network needs, including automation technology as standard.
Leading electricity network operator, SP Energy Networks (SPEN) has energised the UK’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 non-SF6 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 unique product – the only one designed to UK distribution network specifications – 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. Taking up the same space as traditional switchgear, Sabre EcoTec is also designed to fit within the existing substation footprint and can be directly mounted to the transformer, removing any need for costly adaptations.
This first installation is a vital step on SPEN’s journey to develop what it’s calling ‘truly sustainable substations’, which will be environmentally sustainable at every stage of development - from design through construction to operation.
Eddie Mulholland, Process and Technology Director at SP Energy Networks said: “This is a huge milestone, not just for SP Energy Networks, but for our industry as a whole, as we strive to decarbonise the grid and support a cleaner and greener future for us all. It’s been fantastic to work with Lucy Electric to develop and deliver this innovative, sustainable, and cost-effective technology, which gives us the quality and performance we need without the greenhouse gas emissions. It’s a real win-win.
“As the only electricity network operator in the UK to serve communities across England, Scotland and Wales, SP Energy Networks is leading the way and there will be more to come as we work with partners like Lucy Electric to deliver a better future, quicker.” John Griffiths, CEO Lucy Electric commented: “Lucy Electric is proud to be at the forefront of technological development for utilities. Through close collaboration with trusted partners such as SP Energy Networks, we have developed and energised the UK’s first non-SF6 ring main unit, reducing emissions for UK network operators efficiently and cost-effectively. If implemented across the UK, EcoTec could save millions of tonnes of CO2 equivalent per year. “We look forward to rolling out more EcoTec units to serve the growing package substation market in the UK and beyond. At Lucy Electric, we remain committed to ensuring our utility partners are prepared for future regulatory changes and contribute to Net Zero goals and wider societal benefits.”

Chelmsford Family Business KT & MJA Solar Ltd Wins Clean Energy Award
KT & MJA Solar Ltd, a Chelmsford-based renewable energy business, has been named Family Business of the Year 2025 at the Clean Energy Awards just 15 months after launching.
Founded by Kevin Weedon in February 2023, KT & MJA Solar is a family-run company built with future generations in mind. Their three children – including 11-year-old Archie, who designed the company’s logo at age 9 – are at the heart of the brand, with the company name reflecting the initials of each family member. Their rise has been rapid. From humble beginnings and no income during its setup phase, KT & MJA Solar now completes four solar installations every week across the UK – including a standout 64-panel, £38,000 domestic install in Brentwood earlier this year. As families across the UK look to reduce their energy bills and prepare for another unpredictable summer, the company has responded with a seasonal offer: a free air conditioning unit with every solar panel and battery install – helping homeowners regulate indoor temperatures while cutting carbon emissions. Director Kevin Weedon said: “We started this with nothing but belief, hard work, and a desire to build something lasting for our children. There were long nights, moments of doubt, and times we asked ourselves if it was even possible. But we’ve grown through word of mouth, referrals, and trust. To now be recognised as Family Business of the Year is a massive honour.”
Unlike many national providers, KT & MJA Solar prioritises in-person technical surveys before quoting – assessing roof angles, load capacity, and cable runs to ensure

every system is tailored for performance and longevity. This hands-on approach has contributed to a surge in customer satisfaction, with positive reviews stacking up across Facebook, Instagram, and Trustpilot.
The company is now MCS certified, an Octopus Energy preferred partner, and a TrustMark government-endorsed supplier – a sign of its rapid ascent in a saturated market.
KT & MJA Solar has also confirmed attendance at multiple county shows throughout 2025 where they’ll be showcasing the benefits of solar to thousands of households and businesses..
