The pipeline of initial public offerings in the European renewables industry is filling up for a busy final quarter of the year, as Belgium's Hansen Transmission, which manufactures gearboxes for wind turbines, is expected to announce its listing plans this week.

Hansen is currently owned by Suzlon Energy, an Indian renewable energy company and one of the world's leading manufacturers of wind turbine generators. Merrill Lynch and Goldman Sachs have been appointed joint bookrunners on the deal.
