Specialist high-voltage design consultants.
SG Power Distribution is a NERS-accredited, specialist high-voltage electrical design consultancy. We design electrical infrastructure up to 400 kV — connecting renewable generation, data centres, EV charging and development sites to the UK distribution and transmission network. From the first feasibility study through to energisation, we deliver full turnkey design across network design, power system studies, earthing, civil design, cable route design and private networks — working to G81, ENA, IEC and British Standards, and adopted by DNOs and IDNOs nationwide.
Independent, technically rigorous and client-led, we combine deep specialist expertise with a genuine understanding of each project's commercial and programme drivers — giving developers, contractors, ICPs and network operators a single, coordinated design partner from concept to connection.
