(GWA) As a measuring station operator or on their behalf, the GWA ensures the technical operation of an intelligent measuring system. The GWA exists in Electromobility only as soon as one or more energy economy metres are involved in a charging process. In addition, these metres must also be part of an intelligent measurement system (iMSys), which means that they are also connected to a Smart Metre Gateway (SMGW). The GWA can be a natural or legal person.
