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.

Standardization request M/441 and CG-SM

The EC mandated the 3 European Standards Organizations (ESOs) to develop and open architecture for utility meters involving communication protocols enabling interoperability (smart metering). This was foreseen as requiring European Standards to enable the interoperability of utility meters to improve customers’ awareness of their actual consumption.

The ESOs agreed to combine expertise and established a joint group to provide a focal point regarding the standardisation issues. The group produce TR 50572 which identified the functional entities and interfaces to be addressed by the communication standards. 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.

The 'Minimum Security Requirements for smart metering' - is also available.

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

Our Smart Machine-to-Machine communications Technical Committee (TC SmartM2M) actively supports the oneM2M global initiative, especially in relation to European Commission (EC) driven activities, bridging the EC’s needs in the M2M/IoT area and the technical work in oneM2M and other ETSI activities.

TC SmartM2M focus is on an application-independent ‘horizontal’ service platform with architecture capable of supporting a very wide range of services including smart metering, smart grids, eHealth, city automation (smart cities), consumer applications, car automation and smart appliances.

Smart appliances have been specified on request of EC DG Connect. The smart appliances specifications are based on the oneM2M communication framework complemented with Smart Appliance REFerence (SAREF) ontology. SAREF work has contributed to the foundations of the base ontology of oneM2M Release 2. TC SmartM2M developed smart appliances' reference ontology and oneM2M mapping standards and smart appliance testing standards.

CG-SM lead and other ETSI groups involved in Smart Meters

ETSI Smart Machine-to-Machine communications Technical Committee (TC SmartM2M) was the lead ETSI Technical Body/TB for the coordination of ETSI's responses to the EC mandate on Smart Meters (M/441) and is now the main ETSI entry point of ETSI participation in CEN/CENELEC/ETSI Smart Meters Coordination Group (CG-SM) with other ETSI TBs that have interest in smart meters and to take part potentially in CG-SM:

  • ATTM
  • ERM including TG28 (SRD) LTN
  • SCP
  • MSG (3GPP)
