CG has been awarded the contract for the design, engineering, supply and installation of the Onshore and Offshore Substations at the 219MW Humber Gateway offshore wind farm in UK. Humber Gateway is a Round 2 Offshore Wind Project owned by E.ON.

The scheme is based on 73 multi megawatt turbines, power from which will be collected and delivered to the 280 MVA offshore substation platform. It will be transformed up to 132 kV and delivered onshore via 2 export cables to a new National Grid substation 30 km inland at Hedon on Staithes Road, Hull in the north-east of England. CG’s scope in the contract includes detailed electrical system design with grid code compliance, supply of a high voltage Offshore Substation consisting of two step up power transformers, medium voltage and high voltage GIS installed by E.ON on a single jacket foundation and a 132/275 kV onshore substation works including two large autotransformers, reactive power compensation equipment, high voltage switchgear, an IEC 61850 based SCADA, protection and  control, and civil works. The substations are scheduled to be installed and commissioned in 2013 and to become fully operational in early 2014.
