The MT631 modular electricity meter was developed specifically for the German market to meet the requirements of MID and national approval according to the valid standardization (IEC 62052-31 and MID approvals – measurement and safety), MsbG, FNN Basiszähler, and BSI security standards.
Its modular architecture, improved measurement stability, and integrated support for wM-Bus make it future-proof for prosumer integration, and the ambitious rollout targets of Germany’s smart metering program.

Germany is entering a decisive phase in its energy transition. From 2025, smart meter installations will be mandatory, with a full nationwide rollout planned by 2032. This transformation demands flexible electricity tariffs for all customers, strict security and privacy requirements, ambitious renewables and EV targets and active customer engagement.
For utilities, the challenge is immense: annual installations must grow from around 300,000 in 2022 to nearly 2 million to meet national targets. At the same time, the grid must handle more prosumers, EV charging points and variable renewable generation— all while engaging customers in new tariff models and energy-saving habits.
To succeed, smart meters in Germany must comply with the country’s strict regulatory and technical standards (MsbG, FNN Basiszähler, BSI security, MID/IEC safety), ensure secure and GDPR-compliant data handling, seamlessly connect to certified smart meter gateways, and deliver reliable performance over a service life of more than 20 years.
Aligned with MID and national approval according to the valid standardization (IEC 62052-31 in MID approvals (measurement & safety), BSI TR-03109, IEC 62052-31 safety, and FNN Basiszähler compliant.
