Delta HV provided the electrical design, installation, testing and commissioning scope for a new 132kV supply supporting energy recovery operations, delivered across a 10.6km route including tidal river pipe-bridge crossings and directional drilling.
Delta HV provided the electrical design, installation, testing and commissioning scope for a new 132kV supply supporting energy recovery operations, delivered across a 10.6km route including tidal river pipe-bridge crossings and directional drilling. Delta HV engineered the protection and interface schemes, delivered the substation electrical engineering, installed and tested the high voltage route, and took the connection through commissioning, adoption and energisation to produce a compliant, adoptable and durable grid connection.






Multiple constrained crossings required compliant HV containment solutions engineered to survive a tidal, flood-exposed environment: precast parapet-mounted containment with insulated stainless-steel ducts, Ø610mm CHS pipe bridges on piled plinths above the 1:100 + climate change fluvial level, and PTFE sliding bearings to absorb thermal and structural movement without compromising circuit integrity.
