A Microgrid in Saint-Julien-en-Quint, Auvergne-Rhône-Alpes – Technical and Economic Evaluation

PART OF PEGASUS PROJECT

In the frame of PEGASUS, Auvergne-Rhône-Alpes Energy Agency experimented the new legal framework of “collective self-consumption” in the small village of Saint Julien-en-Quint.

In the village of “Saint-Julien-en-Quint”, power outages can occur after strong winds and threaten the electricity supply for farmers’ cold stores or woodchip boilers. As a result, local representatives and inhabitants were searching for innovative solutions that can help the village to become more independent regarding its energy supply, thanks to local energy sources. For this purpose, “SAS Centrales Villageoises ACoPrEV Val de Quint” was formed in June 2018. It is a company with mainly citizen capital and a local cooperative governance investing in photovoltaic equipment installed on roofs.

From an economic perspective, the proposed collective self-consumption needs to be able to strike a balance between at least three parameters:

  • profitability for the producer, to be able to recover their investment.
  • consumers being able to buy locally generated electricity at a price not exceeding that of their current bill.
  • the fact that the back-up suppliers of the consumers concerned are able to make an adapted offer on the part not coming from local production.

Check out the economic and technical evaluations (in french) below and learn more about the feasibility of such configurations.
