Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Smart Metering (DE)

Energy Transition Digitisation Act

The Energy Transition Digitisation Act is a German federal act for the installation and operation of intelligent measurement systems (smart meters) for the implementation and further advancement of the energy transition. The law has been in effect since 2 September 2016. The core of the act is the new Metering Point Operation Act (MsbG), which bundles the requirements for the metering and the meter point operation. It regulates the technical requirements, the financing and the data communication to lay the foundation for the introduction of smart metering systems.  

The interim model

The Federal Network Agency defined the adaptation of the requirements for electronic market communication based on the Metering Point Operation Act on 20 December 2016 by means of an interim model. The interim model should serve for integration of intelligent measurement systems and modern measurement equipment into the existing market processes for applications as of 2017 and calls here for star-shaped communication with the transmission system operators (TSOs) for renewable energy systems. One particular prerequisite for this is the exchange of communication parameters and certificate information in advance between the transmission system operators, the metering point operators and the smart metering system. The implementation deadline for the interim model is 1 October 2017.  

The corresponding descriptions and application aids will be developed by the Bundesverband der Energie- und Wasserwirtschaft e.V. (BDEW, German Association of Energy and Water Industries), and current versions are published under the following link:


  • TSO: Transmission Network Operator
  • MPO: Metering Point Operator
  • iMS: Intelligent Measurement System ("Smart Meter")
  • EMP: External Market Participant
  • MsbG: Messstellenbetriebsgesetz (Metering Point Operation Act)

There is also a reference here to the definitions established by the Federal Network Agency for adaptation of the electronic market communication to the requirements of the Energy Transition Digitisation Act.
