The statutory General Assembly of the new SPL was held in the presence of the mayors of the three towns and elected officials from Sipperec, the inter-municipal union for energy and communication networks on the outskirts of Paris. Marie-Pierre Limoge was elected President and Julie Charitat was appointed General Director.
The next step for GéoSud92 will be to launch geothermal drilling which is expected to commence by the fourth quarter of 2025 at the Panorama sports complex in Fontenay-aux-Roses. The heat network will then be deployed from 2026 starting in Fontenay-aux-Rose, then in Sceaux in 2027, and finally in Bourg-la-Reine. The first heat supply is expected by 2027.
The project is estimated to cost nearly EUR 63 million.

The future geothermal heating network is expected to supply the equivalent of the demand of about 15,000 homes. The network will include social housing, condominiums, and public and tertiary buildings. Their occupants will have access to local and renewable energy at reduced and controlled long-term prices of around EUR 100/MWh. This is 10 to 15% cheaper than individual gas heating.
“They will pay a subscription indexed to investment costs and stable over time, which will represent between 60 and 75% of the total bill, the rest will cover operating costs ,” according to a statement by Sipperec. “The user connected to geothermal energy will thus be less impacted by the variability of energy prices on the markets than a user heated with gas.”
