Wind turbine in Denmark takes energy generation record


A V164 offshore wind turbine from Danish company MHI Vestas Offshore Wind has been able to produce almost 216,000 kWh over a 24-hour period during tests at its site near Østerild, Denmark in December.

Initially developed in 2012 and launched two years later, the 9 MW prototype, which is a reworked version of the V164-8.0 MW, has taken the energy generation record for a commercially available offshore wind turbine.

Since its launch in 2014, the wind turbines have essentially been in competition with itself, due to its superior size over the competition. The V164 stands at 722 ft at full height, with 38-ton blades that are 263 ft in length for a total sweep area of 227,377 sq ft.

The larger the size, the greater the efficiency tends to be, meaning a reduction in installation and maintenance costs per kilowatts produced. The V164 is also built to withstand harsh North Sea conditions, while 80% of the turbine is able to be recycled at the end of its 25-year operational life. It’s designed for optimal wind speeds of 27-56 mph, with a minimum or cut-in wind speed of 9 mph.

“We are confident that the 9 MW machine has now proven that it is ready for the market and we believe that our wind turbine will play an integral part in enabling the offshore industry to continue to drive down the cost of energy,” said Torben Hvid Larsen, company CTO. The energy generation record set on December 1 by the prototype now stands at 215,999.1 kWh produced over a 24-hour period.
