Highleadon Solar Farm & Battery Storage Infrastructure Project

The Highleadon Solar Farm project consisted of a large-scale 49.9MW solar energy development extending across more than 30 individual fields within Gloucestershire. The project incorporated solar PV generation, battery storage systems, high-voltage electrical infrastructure and National Grid connections.

FlowCore MEP Ltd was responsible for the installation and commissioning of critical 33kV inverter infrastructure serving the solar generation systems. The works included the installation of 400mm² single-core aluminium conductors, duct preparation and cable installation throughout the site.

As part of the inverter installations, FlowCore installed 500A DC fuse protection systems for positive DC circuits and completed insulation resistance testing of all cabling using 2.5kV insulation test procedures to verify cable integrity and ensure compliance with project specifications.

The project included 13 primary inverter installations, each supplying multiple secondary inverter systems controlling the solar arrays located across the site. In total, the installation incorporated approximately 20 secondary inverter units supporting the extensive field-mounted solar PV infrastructure.

The overall development also incorporated dedicated transformer infrastructure and high-voltage grid connections linking the site into the National Grid network, providing long-term renewable energy generation capacity for the region.
