Horns Rev 2

2009 we inaugurated Horns Rev 2, which at the time was the world's largest offshore wind farm

​In autumn 2009 we inaugurated Horns Rev 2, which at the time was the world's largest offshore wind farm. The 91 turbines are able to supply the annual electricity consumption of approximately 200,000 households.

  • First residential platform in connection with an offshore wind farm

  • Climate partnerships contribute to Horns Rev 2

Horns Rev 2 is comprised of 91 wind turbines. Each turbine has a capacity of 2.3 MW. Its expected annual electrical output of 800 GW/h is enough to cover the annual electricity consumption of approximately 200,000 households. Horns Rev 2 is 100%-owned by DONG Energy, and more than 2,300 people were involved in its construction.

​Sharing knowledge

Horns Rev 2 is situated further from the mainland than any other large offshore wind farm in the world to date. Construction at sea far from land was a challenging task, but we were able to draw on our experience from the construction of previous offshore wind farms, as well as our Exploration & Production business unit.

 

 

World's first foundation in both steel and reinforced concrete

​Horns Rev 2 was also the first time in the history of offshore wind farm construction that a foundation consisting of a mixture of steel and reinforced concrete was used. The foundations are consequently more resistant to the extreme conditions offshore.

DONG Energy has also purpose-built an onshore prototype to test the construction and design of the new foundations. We have trained personnel in the difficult task of mounting cables on the prototype foundation, to prepare them in the best possible way for the "real" job far out at sea. This solution has proved to be cost-effective, as it is much less expensive to fix things onshore than offshore. Any mistake eliminated in advance benefits the economy of the offshore project.

Climate partnerships

​The idea behind a climate partnership is simple: we help a company or an organisation to realise energy savings. The company may subsequently choose to use these savings to buy energy from wind turbines.

Climate partners have contributed to Horns Rev 2

​This is also the first time that a large-scale wind farm project features climate partnership agreement. This means that each climate partner commits to buying power from the wind farm for a specific period of time.

First time in history

​The residential platform is yet another example of how DONG Energy has succeeded in taking offshore wind energy to the next level. Horns Rev 2 is the first time in history that a residential platform has been installed in connection with an offshore wind farm. This reduces transport to and from the wind farm.
