A smart meter is an electronic device that records consumption of electricity, gas or water and communicates that information for monitoring and billing. Smart meters send meter readings to the utility company automatically. They also come with in-home displays, which give users real-time feedback on their energy or water usage and what it is costing.

The EU Directives concerning common rules for the internal market for electricity and gas (2009/72/EC and 2009/73/EC) and the EU Directive on energy efficiency (2012/27/EU) require Member States to ensure the implementation of 'intelligent metering systems' that shall assist the active participation of consumers in the energy market. The European Commission and EFTA mandated CEN, CENELEC and ETSI (Mandate M/441) in 2009 to develop an open architecture for utility meters involving communication protocols enabling interoperability (smart metering).

Standardization request M/441 and CG-SM

The ESOs (CEN, CENELEC and ETSI) agreed to combine expertise and established a joint group to provide a focal point regarding the standardization issues. The second phase under the standardization request was completed and the following reports were completed from 2013 to 2016:

  • Privacy and Security approach – part I
    The Report describes an approach to define privacy and security requirements for Smart Metering and the status of work carried out by CEN, CENELEC and ETSI on incorporation of security mechanisms to the standards 
  • Privacy and Security approach – part II
    The document describes a repository of requirements applicable in different Member States and compares approaches on security certification schemes for Smart Metering.
  • Privacy and Security approach – part III
    The third report comprises a description of a repository of security threats, recommendations regarding security certification and an update of the status of work carried out by CEN, CENELEC and ETSI.
  • Privacy and Security approach – part IV
    The Report includes a summary of the minimum security requirements defined by the SM-CG Task Force Privacy & Security together with ESMIG, an update on the work of Expert Group 2 of the EC Smart Grid Task Force and an update of the status of work carried out by CEN, CENELEC and ETSI related to security

and CG-SM developed a report on the 'Minimum Security Requirements for smart metering'.

The group (now known as the CEN/CENELEC/ETSI CG on Smart Meters (CG-SM)) continues to give input to the development and maintenance of new and existing standards for advance metering infrastructures in support of the European roll-out of smart meters.

Our Role & Activities

The Co-ordination Group on Smart Meters (CG-SM) works closely with Smart Energy Grid Coordination Group - CG-SEG - (Smart Energy Grids) and in ETSI the participants of CG-SM and CG-SEG have been grouped together with a common lead role of the Technical committee for Access, Terminals, Transmission and Multiplexing (ATTM) with other ETSI TBs that indicated their interest to take part in CG-SM:

  • ATTM
  • SmartM2M
  • CIM
  • OEU
  • EE
  • ERM
  • SCP
  • MSG (3GPP)

For instance, the TC SCP core platform specification defining the interface between a UICC and a terminal (TS 102 221) is also one of the mandated specifications for the smart meter work item of EC and EFTA (M/441).
