Statoil Wind Ltd (Statoil), Statkraft UK Ltd (Statkraft) and Masdar are jointly undertaking the development of Offshore Wind Farm project in north Norfolk, the UK.

The project involves the construction of an offshore wind farm with a capacity of 402MW. It includes the construction of a substation in Breckland District, buried cable system (cable route) includes 38km offshore and 48km onshore, the installation of generators, 67 wind turbines and transformers and the laying of transmission lines.

Warwick Energy will provide advice and support to Statoil Wind Ltd and Statkraft UK Ltd. Royal Haskoning DHV was appointed as environmental consultant for the project.

The planning application for the offshore components of the project were submitted to the Department of Energy and Climate Change (DECC) and the Department for Environment, Food and Rural Affairs (Defra) in June 2009 and the offshore consents were awarded in July 2012.

The planning permissions for the main buried onshore cable sections within Breckland district and North Norfolk district were granted in October 2010 and June 2012 respectively.

In October 2012, project secured planning permission from Breckland Council to move forward with the construction of substation.

In July 2013, Statoil and Statkraft revised the plans for the project.

In February 2014, ABB won US$55 million contract to supply a submarine AC (alternating current) power cable system. Electricity generated by the wind farm will be brought to shore via a seabed cable at Weybourne Hope, some five kilometers west of the coastal town of Sheringham. From there, an underground cable will be laid to carry the electricity to Necton, where a purpose-built substation will enable it to be transmitted into the national grid.

In March 2014, Atkins was awarded a front end engineering design (FEED) contract. The scope of contract will cover all design and engineering services for the project.

In April 2014, Department of Energy and Climate Change (DECC) has awarded an investment contract which gives the guarantee of a minimum electricity price over 15 years also the contract for difference has been awarded.
