The nationwide rollout of intelligent measurement systems is set to begin once the German Federal Office for Information Security (BSI) has completed device certification.
Digitalisation of measuring systems in the energy sector is now underway. The Smart Meters Operation Act (MsbG), which entered into force in September 2016, prescribed the use of intelligent metering systems consisting of smart meters and smart meter gateways (SMGW).
According to the stipulations of the Act, by 2017 all households consuming more than 10,000 kWh must be fitted with intelligent metering systems. By 2020, households consuming more than 6,000 kWh are required to be fitted with smart meters.
The Open Metering System (OMS) is the "system definition across Europe which integrates all media (electricity, gas, heat and water incl. submetering) into one system. It was developed by the industry in order to guarantee a future-proof communication standard and interoperability between all the meter products."
A large German energy supplier has already ordered 16,000 OMS-based SMGWs, which were approved by the Physikalisch-Technische Bundesanstalt (PTB, the German national test authority) in April 2018. EnBW and Netze BW completed their ALC (assurance class life cycle) test with gateways from OMS-Group member Landis+Gyr in February of this year.
The gateways developed by OMS-Group members, Discovergy GmbH and Landis+Gyr GmbH have been registered for certification at the BSI.
Once a minimum of three SMGWs have been approved by BSI, the “market declaration” then permits SMGW's nationwide rollout. The strict requirements are due to the high demands on data protection and data security with regard to encrypted communication. The latter is intended to prevent hackers from manipulating the smart meters or spying on the habits of the users concerned.
By switching to intelligent measuring systems, end-users can look forward to greater transparency and the resulting savings in consumption.
