Construction work on the Zuidwester wind farm is in full swing on the dyke along the shore of the IJsselmeer. Yesterday, the first of twelve wind turbines has been successfully put into operation. Fifty turbines installed during the late 1980s and early 1990s are being replaced by large new turbines. Each of the new Zuidwester turbines can generate as much electricity as all 50 turbines of the old wind farm combined. The new Enercon onshore wind turbines are the largest in the world with a hub height of 135 metres and a capacity of 7.5 megawatts (MW) each. The total investment is over €150 million.
