project brief
The client required the delivery of a 6.5km civil infrastructure route, primarily within public highways, as part of a 60MVA 132kV Data Centre connection in Hemel Hempstead, Hertfordshire.
key project deliverables
- JSM constructed a dedicated 11kV substation, a 132kV dual transformer bund area, and an iDNO-adoptable 132kV switchgear compound
- Temporary power was required during substation works, resulting in 1.6km of 11kV cables being installed. This prevented delays to the client’s energisation requirements
- The Special Engineering Difficulties included bypassing a bridge. Horizontal Directional Drilling (HDD) was used to ensure no disruption to traffic
