The last of the 67 wind turbines at the Dudgeon offshore wind farm was installed earlier this month, and they are all now producing electricity.

During October, they are expected to generate enough electricity to power 410,000 homes.

Situated 32km off the coast of Norfolk, the wind farm was completed at the agreed time and below the £1.5 billion budget that was set when the investment decision was made in 2014.

The first turbine was installed at the beginning of the year, and the first households received electricity at the beginning of February.

Irene Rummelhoff, executive vice-president for New Energy Solutions at Statoil (www.statoil.com), said: “Dudgeon offshore wind farm is part of Statoil’s strategy of gradually supplementing our oil and gas portfolio with profitable renewable energy.

"Offshore wind has been a natural place to start, as we can build on our maritime expertise, our experience from complex projects and our supplier chain.

"With Dudgeon in full production, Statoil is well on its way to providing more than one million households in Europe with renewable electricity.”
