Addition of global assessment, inspection and advisory services to expand UL's capabilities in fast growing renewable energy sector

NORTHBROOK, Ill.  - April 3, 2012 - UL, a world leader in advancing safety, has entered into a definitive agreement to acquire DEWI, a world leader in wind energy measurement and testing services, from the German state of Lower Saxony.  Additionally, UL has agreed to acquire DEWI's 50.8 percent 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 rapidly from a local research and development resource to an international leader 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.

"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."

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 percent by 2015.[1]  DEWI 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.


Headquartered at Wilhelmshaven, Germany, DEWI GmbH or the Deutsches Windenergie Institut is an organization that completely caters to the wind energy sector, associated investors and developers. DEWI has been involved with the fundamental research in this field and the growth of measuring techniques in order to support and sustain this industry. Several services and tasks associated with the swift improvement of wind energy as well as creation of the wind farms are done by DEWI. In 1990, this independent company was established by the Federal State of Lower Saxony in Wilhelmshaven.
