A Smart Meter Gateway (SMGW) is the central element of an intelligent metering system. The SMGW is subject to the high security requirements of the Metering Point Operation Act (Germ. MsbG), as it represents the communication unit of the system. The Smart Meter Gateway stores data, processes it and sends it to the market players. Therefore, all communication flows must be encrypted. To start the official smart meter roll-out, three SMGW providers must be certified by the German Federal Office for Information Security (BSI). Until now, only one provider has met the criteria, with further certifications having been estimated during the course of 2019.
