Featured Case Studies

Jamesfield 49MW BESS Project

Our teams provided the Civil and Electrical works associated with a new 49MW Battery Energy Storage System (BESS).

Humber Cluster Energy Saving Campaign

ABP identified a number of Transformer Assets that are progressing in age and have a considerable number of losses when they are transforming the High Voltage Network down to the localised Low Voltage requirement.

Ferrybridge 150MW BESS Project

OCU were awarded the contract by Scottish and Southern Energy Renewables Ltd for the Design, Construction, Commissioning and Handover of the 132kV/33kV Electrical Infrastructure and Substation Plant and Control Systems.

Capenhurst 100MW BESS Project

Capenhurst is a 100MW Battery Energy Storage System (BESS) connected to the National Grid (NGET) at 275kV.
