Siemens Wind Power said on Wednesday two senior executives will leave the company, one to a firm in Denmark, a leading producer of wind turbines and a major consumer of renewable energy.
A spokesman from Siemens Wind Power, a Denmark-based unit of Siemens AG, said Henrik Stiesdal, chief technology officer, will retire at the end of the year and be replaced by Morten Rasmussen, also from Siemens.
Jan Kjaersgaard, chief executive for onshore wind power, will leave by the end of September "to join another Danish company", spokesman John Pedersen said. He declined to name the company and said a replacement for Kjaersgaard is still being sought.
Siemens's wind unit is not far behind Denmark's Vestas Wind Systems, the world's largest wind turbine maker by market share.
According to media specialising in renewable energy and wind power, Stiesdal is a pioneer of modern wind energy and a former Vestas employee whose design for a turbine in 1978 dominated the field throughout the 1980s.
