The European Commission has provided a set of minimum functionalities for smart meters, to enable member states to identify common means of achieving cost efficiencies and inefficiencies in their roll-out plans.

There are 10 functionalities and they are:

For the customer:

  • Provides readings from the meter to the customer and to equipment that he may have installed
  • Updates these readings frequently enough to allow the information to be used to achieve energy savings.

For the meter operator:

  • Allows remote reading of meter registers by the meter operator
  • Provides two-way communication between the meter and external networks for maintenance and control of the meter
  • Allows readings to be taken frequently enough to allow the information to be used for network planning.

For commercial aspects of energy supply:

  • Supports advanced tariff systems, including multiple tariffs, time of use registers, block tariff registers, remote tariff control, etc. as applicable
  • Allows remote on/off control of the supply and/or flow or power limitation.

For security and privacy:

  • Provides secure data communications
  • Fraud prevention and detection.

To allow distributed generation:

  • Provides import/export and reactive metering.

The three functionalities on which there was limited consensus are:

  • For the customer: Provides the readings in a form easily understood by the untrained consumer, and with calculations enabling final customers to better control their energy consumption, e.g. in terms of cost, as averages, as comparisons to other periods, etc.
  • For the meter operator: Provides for the monitoring of power quality
  • For commercial aspects of energy supply: Supports energy supply by prepayment and on credit.
There are around two-thirds of European Member states that haven’t yet performed smart meter cost-benefit analyses and they are advised to use this set of functionalities when they do so.
The functionalities could also assist member states and the metering industry to facilitate roll-out associated procurement and provide regulators with European reference definitions.
