DEWI GmbH was founded in 1990 in Wilhelmshaven by the Federal State of Lower Saxony for the purpose of supporting the wind energy industry. Since then the company has been closely involved in the rapid development of wind energy, whether in basic research, development of measuring methods, political decision-making or in numerous tasks and services connected with the realisation of wind farms. Since June 2012 DEWI is part of UL (Underwriters Laboratories).

While in the early years DEWI’s activities concentrated on research, the services sector quickly gained in importance and today accounts for more than 85 % of company turnover. Our customers benefit from this combination of research and services, because it ensures that our services are always based on the latest findings.

DEWI‘s expansion into the international market has led to a rapid growth of the company since 1998. Visible signs of this development are our offices in Spain, France, Turkey, Brazil, Canada, Italy and China and the fact that our services are offered in more than 53 countries around the world. As an independent company, DEWI provides all kinds of services for the wind energy industry, developers and investors. The foundation of DEWI-OCC Offshore and Certification Centre GmbH in Cuxhaven in 2003 not only marked the DEWI Group’s entry into the important field of wind turbine certifications; it also ensured that the company is today well prepared for the future challenges of offshore wind energy. Today more than 150 employees are working with the DEWI Group on the future of wind energy, true to our motto:

DEWI, Quality by Know-how.
