Iris HV Engineering provides specialist electrical design services for high-voltage substations, from initial concept through to detailed design and IFC documentation. Our experience covers primary substations up to 400kV, as well as the associated secondary systems required to deliver a safe, reliable and fully integrated installation.

Our design capability encompasses HV AIS and GIS interfaces, transformers, HV and MV cables, protection and control, SCADA, LVAC, earthing, lightning protection and insulation coordination. We develop practical designs that consider the complete electrical system rather than individual items of equipment in isolation.

Whether developing a new substation, modifying an existing installation or supporting a wider EPC design team, Iris HV Engineering provides independent, technically robust design expertise tailored to the requirements of the project, network operator and end client.
