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 multi-million pound 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.
CG were successful against established industry competition in securing this large reference project in the UK renewable sector. This win demonstrates CG’s local project management strengths, expertise in working to National Grid requirements, onshore and offshore track-record and cost-efficient approach in offering turnkey “Design and Build” grid infrastructure solutions that have been recognised by the client in awarding this strategic project to CG.
“The UK will see 18 GW of offshore wind installed by 2020 and this first win provides CG a launchpad to secure a strong market share in this strategic sector and contribute to the UK’s 2020 green energy targets”, says Laurent Demortier, CEO and Managing Director of CG.
