Energy capture squeezes extra output from wind farms
The latest generation of wind turbines are capable of much greater energy capture. Eugene McCarthy reports.

N
ovel technologies, particularly to do with increased energy capture, have led to a raft of new and prototype wind generators coming on to the market in 2014.
Vestas is leading the way with the launch of
its first V164-8.0 MW prototype wind turbine. Tis, says the company, is the world’s most powerful turbine in operation (Fig. 1). “We have now completed the production, testing, and installation of the V164-8.0MW as planned, thanks to the team’s intense effort during a time when Vestas has reduced its investments and lowered fixed costs. We now look forward to evaluating the turbine’s performance on site,” says chief technology officer Anders Vedel.
Te turbine, installed
at the Danish National Test Centre for Large Wind Turbines in Østerild, will be closely monitored in the coming months to further validate reliability and energy output.
Te turbine’s
installation is a key milestone towards ensuring maximum business case certainty for customers investing in offshore wind.
Te V164-8.0MW will be the flagship product for the offshore joint venture between Vestas and Mitsubishi Heavy Industries. One of the new units is capable of supplying electricity for 7500 average European households. With a 140-metre tower,

the turbine at Østerild has a tip height of 220 metres.
Increased energy capture Te swept area of more than 21,000m2
, equal to
three football pitches, increases the amount of energy captured, while reducing operational and maintenance costs by enabling customers to run fewer, larger turbines, with fewer service visits. Depending on the number of orders,
commercial production is expected to begin in 2015. Meanwhile, at the European Wind Energy
