A project experiment with the contribution of smart grids to the electricity system in urban areas equipped with Linky


Number of customers concerned:

  • 1,000 residential customers and 40 tertiary sites


Total budget:

  • €37 million, including €10,6 million funded by Enedis


The Greenlys project offers two demonstration platforms in Grenoble and Lyon, for testing a wide range of smart grid functionalities in urban areas. The project is structured around the Linky smart meter, an interface between the distribution power grid (upstream) and customer’s home (downstream).


  • Demand management / peak shaving
  • Installation of innovative equipment (observation, control)
  • Gestion of ev charging station
  • Big data management
  • Power demand and generation forecasting models and tools
  • Advanced functions for managing the grid (status estimation, voltage regulation, self-healing, demand / production balance, active management of distributed resources...)


Key stages

Individual curtailment capacities characterized and a coordination required between the DSO and demand response aggregators

  • Observation of a power rebound of 25 to 50% of the curtailed power and an energy report of 95% of the curtailed power
    Individual curtailments of 300 LV clients graph: power rebound and energy report
  • In order to anticipate and manage the risks of a concentrated activation of flexibilities in certain locations, coordination required between the DSO and demand response aggregators
  • The panels method via Linky convincing (performance, neutrality) for the control of the achievement of the residential curtailments

Innovative solutions for the LV network observability and control implemented

  • Additional software solutions based on Linky smart meters (LV incidents management, default detection, optimization of the quality of supply) in the industrialization process
  • Testing of solutions enabling the increase of the LV network capacity:
    • LV state estimator
    • LV voltage control
    • demand response forecasting management
    • MV/LV automated substation
    • Fisheye camera to forecast photovoltaic generation
