France (Guadeloupe) - Electricity Generation

France has defined ambitious objectives for electrical geothermal development, but limited to the overseas territory (Guadalupe, in Caribbean Sea); many projects are emerging on the mainland (combined heat and power). The first 1.5 MWe EGS pilot plant at Soultz-sous-Forêts is fully operative (Vernier, et al., 2015).

Development since WGC2010: non new plants since WGC2010.

Installed capacity 16 MWe                     
Geothermal Electricity 115 GWh/y

Geothermal electricity is not available on the mainland, but only in the Caribbean islands it can reach up to 20% of electricity needs.

The high enthalpy utilization for electricity production in France is only in the French Overseas Department, at Bouillante on Guadeloupe island (Geothermie Bouillante). Its exploitation started in 1984, and a second unit in 2004 has been commissioned. The reservoir temperature is 250°C at shallow depth. The total capacity of 15 MW, not increased since 2005, produces 95 GWh, corresponding to 8% of the local consumption. The activity for the third unit of 20 MW is ongoing. The final target will reach 20% of geothermal contribution to the electricity needs.

On the islands of La Martinique and La Réunion, geothermal exploration programs are planned in the near future.

The EGS project at Soultz-sous-Forêts is now operating a scientific pilot plant module of 1.5 MW. The enhanced geothermal system, exploited with a three-well system in the granite formation at depth of 5,000 m, is expected to stabilize its operation in the coming year. In December 2008, the output ranged around 12 MWth for a cumulative flow-rate ranging around 28 l/s. The first kWh has been produced in June 2008.
