EU Energy Licenses Wind Patents with GE and Adds Wind Service

EU Energy Inc., a subsidiary of Composite Technology Corporation (CTC), has licensed certain patents from GE Energy’s wind business that will permit EU Energy to continue to sell its DeWind D6 and D8 wind turbines incorporating the use of conventional power conversion electronics in markets where the GE patents are applicable.

As EU Energy’s range of wind turbines use their own technology and designs, both companies will independently carry on with their respective businesses of designing, manufacturing and selling wind energy turbines. The DeWind D6 is available in 50 Hz and 60 Hz and the DeWind D8 available in 50 Hz. “Developing the renewable wind energy sector is vital to any developed economy and we are pleased to be able to offer our traditional range of D6 and D8 turbines using certain of GE Energy’s power electronics patent portfolio,” said Michael Porter, President of CTC and EU Energy. This license is not applicable to EU Energy’s DeWind D8.2 and D8.1 wind turbines, which use a hydrodynamic torque converter that allows a synchronous generator to connect directly to the grid without the use of power electronics. Previously, CTC completed the reorganization and expansion of its subsidiary, EU Energy Service & Maintenance GmbH, which services and maintains DeWind turbines. As part of the reorganization, agreements with Enertrag AG called for 50% ownership and a name change to E Energy Service GmbH. The reorganization will permit E Energy Service to expand beyond the service and maintenance of wind turbines into subcontracting for the operation of customers’ wind farms. E Energy Service will continue to fulfill the warranty obligations of EU Energy’s installed DeWind turbines.
