DONG Energy has unveiled Horns Rev 2, the world's largest offshore wind farm.
Horns Rev 2 is situated in the North Sea, off Denmark's west coast, and has been constructed at a cost of kr3.5bn ($690m).
The Danish wind farm has 91 d-number turbines, 2.3MW each, spread over 35km².
It has a capacity of about 210MW, making it the largest windfarm in the world, and can annually produce enough green power for 200,000 houses.
The power generated by the wind farm will be purchased by a group of private and public enterprises that have forged 'climate partnerships' with the company.
DONG Energy's chairman of the supervisory board Fritz H Schur said Horns Rev 2 a significant part of the company's transition from conventional to eco-friendly power generation.
DONG Energy aims to treble its renewable power capacity by the year 2020.
As a step towards this goal, the company will unveil five new wind farms. It also has several other projects in the pipeline.
Horns Rev 2 is the ninth wind farm to be established off Denmark's coast since 1991.
