Abstract :
The construction crane hauling wind turbines at the 20¿year-old Nÿrrekÿr Enge wind farm in northern Jutland, Denmark, is performing a highly energetic sleight of hand. By next summer it will have transformed a 77-turbine facility into one with just 13. Amazingly, this reduction will help double the farm¿s energy production. The trick is in the scale of the replacement turbines. At 2.3 megawatts, they should each generate as much peak power from Nÿrrekÿr Enge¿s winds as 8 to 15 of the vintage turbines installed on the site in 1988 and 1990.
