Senvion is offering up to 29.9 million shares from the holdings of the existing shareholders, including over-allotments of 3.9m shares.
Senvion last month announced its upcoming IPO to fund its expansion, but said that its current owners will keep a majority stake.
"Access to the capital markets will support Senvion's growth path and enhance our company's global profile," Senvion chief executive Jürgen Geissinger said.
