This project was Mitsubishi’s first outdoor GIS 132 kV Substation in Europe and also their first time delivering on UKPN’s 132 kV Switchgear framework.

H&MV project managed the installation of the outdoor substation, including offloading and installation of all GIS equipment, above ground earthing, standard inspection/testing, installation, termination and testing of multicore cabling.

The H&MV team accelerated the programme upon request, with 12 hour days, larger crews and weekend working to achieve the clients deadline, dictated by the National Gird Outage Programme.
