Smart Metering

Introduction

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.

Mandate M/441 and CG-SM

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. Regarding electricity, where there was a positive assessment of the long-term costs and benefits, then at least 80% of the households should be equipped with smart metering systems by 2020. In order to address these challenges, 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).

The objective of European Commission Mandate M/441 was the creation of European standards to enable the interoperability of utility meters to improve customers’ awareness of their actual consumption.

In response to Mandate M/441, the European Standardization Organizations (ESOs), CEN, CENELEC and ETSI decided to combine their expertise and resources by establishing the Smart Meters Coordination Group (SM-CG). This group is a joint advisory body that provides a focal point concerning smart metering standardization issues. The first phase of the Mandate M/441 requested the ESOs to produce a European standard for communications. In this context, the SM-CG produced a Technical Report, CEN-CLC-ETSI TR 50572:2011 'Functional reference architecture for communications in smart metering systems', which identifies the functional entities and interfaces that the communications standards should address. It is intended to support the development of software and hardware architecture and related standards. The second phase of Mandate M/441 focused on the development of European Standards containing harmonized solutions for additional functionalities within interoperable frameworks. The SM-CG completed the second phase of M/441 by producing a SM-CG report (pdf format) which summarizes the work undertaken during the period 2009-2012.

In 2013, 2014 and 2016 the Smart Meters Co-ordination Group (SM-CG) finalized the following reports:

  • 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.

A repository was created by the SM-CG in 2015 and now links the original requirements from member states with the minimum requirements. Having completed the work carried out in the framework of Mandate M/441, SM CG still gives input to the development and maintenance of new and existing standards for advanced metering infrastructures in support of the European roll-out of Smart Meters.

SM-CG has been renamed CEN/CENELEC/ETSI Coordination Group on Smart Meter (CG-SM) and works closely with CEN-CENELEC-ETSI Smart Energy Grid Coordination Group CG-SEG.

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
  • PLT (including OSGP)
  • SCP
  • MSG (3GPP)
