Communauté de Communes Cœur de Savoie

The Community of Communes Cœur de Savoie is a peri-urban, mainly residential area located at the crossroad of three valleys in the Auvergne-Rhône-Alpes region.

In this region, the Sun4All support scheme will be applied and tested to subsidise vulnerable households, which suffer from high energy costs.

Why here?

Cœur de Savoie is affected by the issue of energy poverty due to multiple reasons. Housing in the Auvergne-Rhône-Alpes region is known to be very energy intensive, due to the specific geographical and climatic conditions in the region. This leads to expenditures for energy being 6 % higher in this area, compared to the French metropolitan average. Approximately 50 % of the households of the municipality have incomes, which fall below the threshold for social housing. Therefore, the social housing stock of the Community of Communes Cœur de Savoie lies above the average of the Savoie department.

With the “Sustainable Energy Action Plan” which was released in December 2020, the region expresses its will to locally react to climate change issues.

Solar installations on rooftops of public buildings located in the region will generate the solar energy dedicated to the Sun4All project. The produced energy will be evenly credited on the participants’ energy bills and lead to a reduction of their actual energy costs. Each Sun4All beneficiary, mainly residents of poorly insulated housing units, will receive a share of 0.5 kW. It is expected that this share corresponds to approximately 30 % of the beneficiaries’ energy consumption.
The Sun4All project offers the opportunity to link the region’s existing and planned solar installations (see map below) with the topic of energy poverty. The Community of Communes Cœur de Savoie aims at providing sufficient renewable energy resources to be able to effectively act against energy poverty.

"Pour le mandat 2020-2026, notre présidente a mis en avant deux enjeux majeurs: la transition écologique et la solidarité. Sun4All nous offre l’opportunité de faire converger ces deux objectifs localement mais également avec nos partenaires européens. C’est une chance!"

5 PV installations on rooftops of public buildings, such as nurseries, schools and administration buildings.

  • 60 kW installed power
  • 25 kW will contribute to the Sun4All project.

In the course of the year 2022, other installations will be installed to contribute to the Sun4All project in the region to expand the reach of the Sun4All project and to be able to support more vulnerable households.

In the upcoming years, the Community of Communes Cœur de Savoie plans to establish a ground-based solar photovoltaic plant with a production capacity of 4,600 kWp.
