The project, which features MHI Vestas V164-8.0 MW wind turbines, is capable of supplying clean electricity to around 230,000 homes,

It is claimed to be the first offshore wind farm to make commercial use of these wind turbines.

Dong Energy owns 50% stake in the wind farm, while its partners PKA and LEGO Group parent firm Kirkbi each own 25% interest.

Dong Energy is also developing an operations facility in Merseyside, which will support Burbo Bank Extension and the existing 90MW Burbo Bank wind farm in the region.

Dong Energy chief executive Henrik Poulsen said: “Burbo Bank Extension showcases the rapid innovation in the offshore wind industry. Less than ten years ago at Burbo Bank, we were the first to install Siemens 3.6MW wind turbines and in this short time, the wind turbines have more than doubled in capacity. 

PKA CEO Peter Damgaard Jensen said: "Since our first investment in an offshore windfarm in 2011, PKA has focused its strategy on investing in renewables and divesting from coal and oil companies.”

In February 2016, Dong Energy had agreed to divest its 50% stake in offshore wind farm project Burbo Bank Extension in the UK to Danish pension provider PKA and Lego Group's parent firm Kirkbi for around £660m.

Under the deal, Dong Energy is also responsible for the sale and delivery of the electricity, which is generated by PKA and Kirkbi.

Currently, Dong operates 17 offshore wind farms across the UK, Germany and Denmark, which feature 1,000 offshore wind turbines.
