Conergy, a renewable energy company, has set the price range for its €243m ($326m) flotation. It will be Germany's first accelerated initial public offering, a special structure in which bookbuilding lasts only three days instead of the usual two weeks.

Conergy is offering 4.5 million shares at between €48 and €54 each. Bookbuilding was launched today and the company is due to list on Thursday.
