International Standards and Conformity Assessment for all electrical, electronic and related technologies


Smart grids


What is a smart grid?

A smart grid is an electricity network that can integrate in a cost efficient manner the behaviour and actions of all users connected to it - generators, consumers and those that do both - in order to ensure economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety (as per the definition given by the Expert Group 1 of the EU Commission Task Force for Smart Grids).

Smart grids and standardization

Standardization is a key issue for smart grids due to the involvement of many different sectors along the value chain - from the generation to the appliances in the households. Because the smart grid is broad in its scope, the potential standards landscape is also very large and complex.

The European Standardization Organization (ESOs), i.e. CEN, CENELEC and ETSI, accepted the standardization Mandate M/490 on smart grid standardization.

The European Commission mandate M/490 highlights the following key points: the need for speedy action; the need to accomodate a huge number of stakeholders and to work in a context where many activities are international.

Standardization of smart grids is not 'business as ussual'.

In order to perform the requested mandated work, the ESOs established in July 2011, together with the relevant stakeholders, the CEN-CENELEC-ETSI Smart Grid Coordination Group (SG-CG), being responsible for coordinating the ESOs reply to M/490 (successor of the JWG on standards for smart grids).


In 2012, the SG-CG Group focussed on the following mandated aspects:


- A Technical Reference Architecture
- A Set of Consistent Standards
- Sustainable Standardization Processes


The ESOs also investigated standards for information security and data privacy.


These reports and additional information on the Smart Grids standardization activities are available on the CEN-CENELEC website.


The focal point addressing the ESO's response to M/490 will be the CEN, CENELEC and ETSI Smart Grids Coordination Group (SG-CG), built around the membership of the previous JWG.
