Pilot installations and solutions in Saint-Julien-en-Quint

Regional Energy and Environment Agency in Auvergne-Rhône-Alpes is studying a microgrid in a small rural village.

In this village, power outages can occur after strong winds and threaten electricity supply for farmers’ cold stores or woodchip boilers. Thus, local representatives and inhabitants are searching for innovative solutions that can help the village to be more dependant from local energy sources.

The perimeter is delimited by all the 45 consumers connected to the main local power substation. They have already equipped 32 houses with measurement devices in the village of Saint Julien-en-Quint. The remaining buildings are mainly unoccupied and it was not relevant to make measurements inside.

These measurements are different according to the type of meter and to the agreement of the owner. They are either located on the electric internal board of the house or located on the meter. Where it was possible they have registered the controllable loads such as electric water tanks.

They also have an online visualization platform where they can monitor power and voltage every 10 minutes. They are trying to get measurements on the local substation as well. At the moment they are in the process of starting the modelisation of the grid.
