Delta HV delivered the full design for a 300MW 132/33kV substation serving a data centre installation, acting as Principal Designer and carrying the scheme through to design acceptance by UK Power Networks. The design brought primary, civil, structural, architectural and protection disciplines together on a tight timescale, supported by 3D modelling to resolve interfaces before construction and by continual engagement with the DNO, manufacturers, the client and the client's main contractor. Delivery in line with UKPN's timelines was the end client's principal driver, and the contestable design was accepted accordingly.






The scheme adopted DNO-approved SF6-free GIS switchgear, with Delta HV among the first to design the interface for the product outside UK Power Networks' own projects. With little precedent to draw on, the arrangement was developed directly with the manufacturer and the DNO and proven in 3D before approval — removing SF6 from the installation while meeting UKPN's design standards and timeline.
