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
CG-SM lead and other ETSI Groups involved in Smart Metering
In the beginning, ETSI Smart Machine-to-Machine communications Technical Committee (TC SmartM2M) has been the lead Technical Body (TB) for the coordination of ETSI's responses to the EC standardization request on Smart Metering (M/441). This lead role has been handed over to Technical Committee for Access, Terminals, Transmission and Multiplexing (ATTM) that is now the main ETSI entry point of ETSI participation in CEN/CENELEC/ETSI Smart Metering Coordination Group (CG-SM) with other ETSI TBs that indicated their interest to take part in CG-SM (like TC ATTM, TC SmartM2M, ISG CIM, ISG OEU, TC EE, TC CYBER, TC ERM, TC SCP, TC MSG (3GPP)). 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).
The Co-ordination Group on Smart Meters (CG-SM) works closely with Smart Energy Grids Coordination Group - CG-SEG.
Smart Metering and SAREF
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, Smart Cities, consumer applications, car automation and Smart Applications (SAREF).
Initially, Smart Appliances have been specified on request of EC DG Connect. The Smart Appliances specifications were based on the oneM2M communication framework (TS 103 267) complemented with Smart Appliance REFerence (that is now Smart Applications REFerence, SAREF V3 TS 103 264) ontology. SAREF work has contributed to the foundations of the base ontology of oneM2M Release 2.
TC SmartM2M developed "SAREF ontology and oneM2M Mapping standards" and Smart Appliance testing standards. For SAREF extension investigation in the energy domain (TS 103 410-1), direct inputs from EEBus and Energy@home have been included in TC SmartM2M developments where Energy, Environment and Building sectors have been part of the first SAREF normative work. Then more SAREF extensions were developed for Smart City, Industry and Manufacturing, Smart Agri-Food, Automotive, eHealth and Ageing-Well Wearables and Smart Water. SAREF for Smart Lift is under construction.
SAREF is recognized as key enabler of IoT Semantic Interoperability with a growing set of enabling published standards (find standards in search ETSI standards with the keyword SAREF).
