A 402MW offshore wind farm has officially been opened in the UK.

The 67-turbine Dudgeon wind farm off the coast of Norfolk is now delivering power to the UK grid, generating enough electricity for around 410,000 homes.

Operator Statoil and partners Masdar and Statkraft said the project’s construction costs have been reduced by more than 15% – from £1.5 billion to around £1.25 billion.

Statoil’s CEO Eldar Sætre added: “Dudgeon represents an important contribution to realising the UK’s renewable energy strategy.

“As part of our strategy to develop from an oil and gas company to a broad energy major, Statoil will grow significantly in profitable renewable energy, with an ambition to invest around NOK100 billion [£9.2bn] towards 2030.”
