Repower scales up unit size -- Prototype 3.3 MW

Google Translate

Repower Systems has installed the prototype of the largest turbine yet in its series for use on land. The 3.3 MW machine has a rotor diameter of 104 metres and is an extension of the German company's 2 MW platform -- a traditional three-blade, pitch controlled concept with a three stage gear box. The turbine has gone up at the Südermarsch wind station near the north German coastal town of Husum close to the Danish border.

Repower says the machine "bridges the gap" between its current onshore products, rated at 1.5 MW and 2 MW, and its 5 MW and 6 MW offshore machines. A second 3.3 MW machine is to be erected at Südermarsch soon. Both machines were assembled in Bremerhaven, where Repower is currently initiating series production of its 5 MW offshore turbine and has just completed assembly of the three first 6 MW machines for installation at the Westre wind farm on the German-Danish border. The machines will be fully tested at that location in preparation for certifying for offshore use. Westre is a community-owned project owned by 200 limited partners resident in the villages of Westre and Ellhöft in Germany and Lydersholm in Denmark.

Meantime, Repower intends to produce 30 of the new 3 MW model during the coming financial year. In the medium term, it plans to construct a new factory for production of the 3 MW turbine at Osterrönfeld, also in the north German region of Schleswig-Holstein.
