MTT has installed and commissioned its initial field trial units at different test locations in Germany. In co-operation with Stadtwerke DREWAG and Stadtwerke Bielefeld, various field trial locations have been selected  such as a school, a multi family home and an office building. As from June 2013,  the field trial units will be in operation at the test locations for a period of 12 months. Throughout  June and July the number of field trial units will be expanded to a total of 10 units, which will be installed at various locations in the Netherlands and Germany.

Main goal in this first phase of the field trials is to validate the reliability of the system and to identify possible improvements.
