Enercon expects to start marketing its new E20 100 kW turbine at the start of 2003, says company owner Aloys Wobben. "We take the recommendations of the G8 Task Force on renewable energies seriously, and its clear that this size of machine is needed for developing countries," he says. At the other end of the size scale, Enercon expects to install a second 4.5 MW prototype at a site near the Lower Saxony port of Wilhelmshaven once the first prototype is running at its Magdeburg-Rothensee works in the summer. The third 4.5 MW will be installed offshore, says Wobben. Enercon is negotiating to supply offshore wind plant to Prokon Nord, the company that looks likely to build the first German wind plant at sea, at Borkum West. Wobben stresses his company is not yet ready to go offshore. "We have great respect for those who are building offshore but we don't have that confidence yet." The 4.5 MW machine will be tested for at least two years, he says.
