Supply the commune of Mazet-Saint-Voy with renewable heat by mobilizing citizens' savings and the ADEME heat fund.
The Commune of Mazet-Saint-Voy has a public service delegation contract with ERE43 to supply multiple public and private buildings with renewable heat. ERE43, is a consulting firm with a cooperative community-oriented enterprise status (SCIC).
Since 2007, five micro-heating plants were installed by ERE43 in the municipality.
The Commune of Mazet-Saint-Voy was invested in supplying renewable heat and to so involving the local community as much as possible.
By the time they were installing their third boiler, they opted for a new model developed by ERE43; Modul’R (commercial name of the boiler room). This new model can be completely disassembled; it consists of a mini-boiler and a wood storage silo and is thus adapted to rural areas where heating supply needs are less important than in cities. The development of this model is also based on a short circuit heating; supplied with local resources in the form of chipped wood or thinning wood.
The fourth boiler room project model was set up and financed thanks to citizens' savings and the ADEME heat fund. In order to support the fundraising at local level and the communication of the project, the involvement of Énergie Partagée was requested.
The rest of the funds were provided by public actors (grant from the Auvergne-Rhône-Alpes Regional Council).
Resources needed
Answer to ADEME's call for projects
Citizen fund raison and communication: Énergie Partagée
Subsidies from the Regional Council
Support for local elected officials in set-up of a citizen project
Between €70,000 and €165,000 per boiler
Out of which 100 k€ from citizen's investment
Evidence of success
Installation of five 100 kW wood boilers by ERE43 in the municipality of Mazet-Saint-Voy, the last of which is financed by the ADEME's heat fund as well as citizen savings gathered by Énergie Partagée.
Production of 70 to 200 MWh/year
Difficulties encountered
The political context at local level concerning the end of mandates made the elected representatives hesitant to invest in this project.
The complexity of the set-up of the ADEME subsidy (fragmented the ADEME’s objective into several boiler rooms).
Potential for learning or transfer
The legal and financial model is replicable in any other municipality, but nevertheless requires good support from actors with expertise in financing the project, particularly in the field of citizen financing.
