A tender has been announced for project management services related to a geothermal heating plant and network project in Fontenay-sous-Bois, France.

The Urban Heating Authority of Fontenay-sous-Bois (Régie Chauffage Urbain de Fontenay-sous-Bois / RCU) has announced a tender for project management services for a planned heat transition project in the town of Fontenay-sous-Bois in Val-de-Marne, France.

The project will involve the construction of a geothermal heating plant, a biomass boiler room, and the implementation of a “smart grid” for the conversion of the heating network owned by RCU.

The deadline for requests to participate for the tender will be on the 3rd of July 2024. All relevant tender documents are linked at this page.

The town of Fontenay-sous-Bois seeks to transition its heating supply from the current 70% gas and 30% wood to a combination of geothermal and biomass. The goal is for the town to achieve 90% renewable energy with between 40 to 50% coming from geothermal. This will save about 31,000 tonnes of CO2 emissions per year and eliminate the release heavy metals.

Aside from drilling a geothermal well to 1800 meters depth and putting up a geothermal heating plant, the heating network will also have to be retrofitted. The wood-fired boiler room currently supplies water at 180 °C, which is then lowered to 80 °C. In contrast, the geothermal well is expected to supply warm water at 62 °C.

Paris already has one of the oldest geothermal heating networks in the world, but geothermal heating in the Greater Paris Area continues to expand. In late 2023, a new geothermal heating plant was inaugurated in Seine-Saint-Denis, supplying geothermal heating partially for the demand of several towns and facilities including the Athletes’ Village for the 2024 Olympics.
