The Societe d´Exploitation de Energies Renouvelables (SEER) has announced the successful completion of a second geothermal doublet in the commune of Ris-Orangis in Essonne, France. The well parameters are also in line with forecasts of a temperature of 73 degrees Celsius and a future maximum operating flowrate of 450 cubic meters per hour.

The new geothermal doublet is expected to come into production by September 2024. This will allow SEER to supply 65% renewable energy to an additional 8,000 homes in the SEER network, and more than 20,000 equivalent housing homes by the end of 2024.

We had first reported on the start of drilling of the second doublet at the start of 2023.  Prior to this, SEER had already drilled a first doublet that had been supplying geothermal heat to the geothermal heating network Grigny and Viry Chatillon. This was inaugurated back in 2018.
