The establishment of a dedicated UESP test site at Fraunhofer ISE has started. Beside the demonstration of UESP systems it will be used for further development of components and system tests. At a later stage, components will here undergo intensive compliance testing before they are able to carry a UESP conformity label. Within the project six different types of power supplies will be set up and tested, many of them in the field. The following table shows the various applications with information on power and energy:

3. The Consortium

Eight German companies have teamed up with Fraunhofer ISE in this challenging project (funded by the German Ministry for the Environment, Nature Conservation and Nuclear Safety, BMU) to define the previously described protocol and interfaces and to elaborate the various implementations. The applications range from village power supply systems to highly reliable telecommunication stations and signalling systems. The business‘ interest ranges from component manufacturers to potential users or operators. The research

institute’s role lies in the development and implementation of the concept and the central software. It is foreseen to establish UESP as standardised interface in the future.
