Smart Meters : developing a smart network

There is a need for increased safety, greater flexibility to prepare for the future and to handle fluctuating demand, and to integrate more and more new resources such as biomethane.

Developing a smart network

In order to tackle all of these challenges, GRDF is developing the network with “Gazpar” smart meters, smart pipes and smart gas grids.
More flexible networks that are able to connect with other urban infrastructures will help build tomorrow’s cities around smart networks.

Intelligent gas network : smart pipes at your service

Smart pipes are based around three key concepts :

  1. Remote surveillance of installations to detect any malfunctions and to ensure the highest quality service possible.
  2. By combining data from the various meters and sensors at key points in the network, remote-sensing will help improve flow reconstruction. Added benefits: improved response in emergency situations, optimized investments, and optimized stocks.
  3. Remote control of certain installations will enable a more even balance between supply and demand.

Smart gas grids interacting with other networks

Smart pipes could help support the electrical power grid, with decentralized production by micro and mini-cogeneration units. In high-density energy areas, heating networks combining renewable energy with gas in central heating systems could be developed.


The interconnection of smart pipes with other urban infrastructures, such as electrical smart grids, will form smart networks. Making these networks communicate will benefit customers by combining their strengths, with each network bringing its own specific advantages.

Towards Smart Gas Grids : Gazpar, GRDF’s smart meter

Modernization of the natural gas network is now underway ! After working in consultation with local and national public authorities in France, under the auspices of the French Energy Regulatory Commission (CRE), GRDF’s new smart gas meter will gradually reach 11 million natural gas customers.


Gazpar’s objectives are to boost customer satisfaction via an automatic, daily reading of their natural gas consumption, to improve their control over the energy they use by making more frequent updates on data consumption available, and to optimize the distribution network by modernizing and improving performance of the natural gas distribution grid.

How does the Gazpar meter work ?

Fitted with a radio module, Gazpar smart meters transmit information on natural gas consumption to a data concentrator, installed on a building roof, twice a day, and take less than a second to do so. The data concentrator, fitted with a SIM card, sends consumption data to GRDF’s information system, which processes the data and makes it accessible to customers.This type of communication is similar to a 15-minute telephone call. Objective : to allow our customers to consult their data consumption, which they can access directly in their personal area on grdf.fr.

This allows our customers to see how much natural gas they are consuming, analyze the information to help make energy savings, and to send this data automatically to their gas suppliers, once a month.

When will Gazpar make its debut ?

After final validation of the Project by the respective French Ministers for Ecology and Economic Affairs in 2014, smart meters is being installed in 24 pilot municipalities across four French administrative districts (Côtes d’Armor, Hauts-de-Seine, Haute-Normandie and Rhône) in 2016. The meters are being deployed throughout France between 2017 and 2022.

Gazpar, facts and figures :

  • 150,000 meters installed in 2016
  • Four administrative regions in France : Ile-de-France Ouest, Haute-Normandie, Bretagne and Rhône-Alpes
  • Eleven million Gazpar meters to be rolled out throughout France between 2017 and 2022.
