April 4, 2012 – UL (Underwriters Laboratories) is acquiring DEWI—a player in wind energy measurement and testing services—from the German state of Lower Saxony.

“Lower Saxony had the vision to plant a seed and nurture an excellent, economically viable business in DEWI, and we’re excited to be giving this extraordinary company a bigger pot in which to grow,” said Gitte Schjotz, president of UL Europe and Latin America. “We are thrilled to be adding DEWI’s high-caliber people and industry- leading capabilities, and will dedicate our global reach, resources and trusted brand to building continued and lasting success.”

Additionally, UL has agreed to acquire DEWI’s 50.8% stake in DEWI-OCC, an accredited DAP (German accreditation) certifier of onshore and offshore wind facilities.

Founded in 1990 to support Germany’s emerging wind energy industry, DEWI has expanded from a local R&D resource to a global player in measurement services, micrositing, research and education, as well as technical and economic advisory services. DEWI is relied upon by more than 1300 customers spanning 13 countries worldwide.


DEWI’s performance and efficacy testing will join UL’s wind energy safety certification services “to better address the evaluation needs of a global wind energy market that is expected to grow 67% by 2015”. It will join UL’s Product Safety business unit and will continue to operate from its facilities in Germany, Spain, France, Italy, Turkey, Canada, Brazil and China.
