Danish energy firm Dong Energy has made the 312MW Borkum Riffgrund 1 wind farm operational offshore of Germany.

Standing around 37km from Borkum island in the North Sea, the facility will meet the electricity demands of nearly 320,000 German homes.

The offshore wind power plant is equipped with 78 Siemens turbines, each with a generation capacity of 3.6MW.

As well as supplying the turbines, Siemens will be responsible for their service and maintenance for an initial ten-year period.

Dong Energy is a 50% stakeholder of the wind power project, with the rest being jointly owned by Kirkbi Invest and William Demant Invest.

Dong Energy board of directors chairman Thomas Thune Andersen said: "Borkum Riffgrund 1 is an impressive example of just how fast offshore installations can now be installed.

"This translates into lower costs and is good news for consumers."

"We are currently building another two offshore wind projects and have a number of other projects in our pipeline that will allow us to demonstrate the skills and competences we have gained and will allow us to continue to show the trust we have in the German offshore wind market."

This is the first operational project for Dong Energy in Germany.

Danish Minister for Energy, Utilities and Climate Lars Lilleholt said: "Germany is Denmark’s main export market, which is also the case when it comes to energy technologies."

Lower Saxony Minister for the Environment, Energy and Climate Protection Stefan Wenzel said: "We need a smooth transition to ensure a continuous build out and realisation of cost reduction potentials.

"Planning certainty is therefore key."
