In February 2013, the EnerTwin received CE certification for field tests. Obtaining this certificate represents an important milestone in the development of the EnerTwin, which began in mid-2008. The certificate was issued by KIWA after extensive safety testing. KIWA’s certificate is valid for all countries within the European Union as well as in Norway, Croatia, Turkey and Switzerland.

Field-testing will start at the end of March 2013, taking some 12 to 18 months to complete. These tests will be performed together with Stadtwerke Bielefeld, Drewag and EON Benelux.
