After the nuclear disaster in Japan, 19 Repowering Roggeplaat, The Netherlands ENERCON E-101/3 MW prototype renewable energies were at the centre of attention more than ever. After 20 years of operation ENERCON’s first wind farm abroad gets new turbines. 2 3 hazards and considerable damage to the WEC Turmbau Emden ENERCON has received indefinite unit certificates environment. Neodymium is needed to make extends production facilities for their E-82 E2/2 MW and 2.3 MW, the the permanent magnets that are used in the E-70 E4/2.3 MW, the E-53 and the E-48 generators of other wind turbine manufacturers. WEC Turmbau Emden, maker of concrete towers turbines. Although still with a prototype status, the The reports made blanket statements about an for wind turbines, is extending its manufacturing E-82 E3/3 MW, E-126/7.5 MW and the E-101 alleged dirty side to the clean wind energy that facilities. This summer, the company put into are considered equal to the certified WECs until presents itself as an environmentally friendly service a third production bay at its site on the measurements have been completed.

The extension media reports suggested, ENERCON wind energy to the factory building with a surface area of converters generate environmentally-friendly 7500 m² is used to produce precast concrete NEWS power totally without neodymium. The gearless segments for the new ENERCON E-101 wind design on which all wind turbine types – from energy converters. the E-33/330 kW to the E-126/7.5 MW – are based employs an annular generator with The structure that is 300 metres long and 100 school children separate excitation.
