Development of high-temperature geothermal energy in the French West Indies (FWI): Key Note speaker

Abstract : In a context of energy transition and steady increase of the population and of energy demand in the Caribbean volcanic islands, the development of geothermal energy can provide base load and competitive electricity in territories faced to the fragility of their energy systems and of their environment. But paradoxically, the Bouillante geothermal plant is the only installed capacity in this region (15 MWe), harnessing a high-temperature (260°C) geothermal field located along the coast of western Guadeloupe, for almost 40 years. Exploited by the Geothermie Bouillante (GB) Company since 1995, it presently produces about 110 GWh from two units, supplied with steam by two deep wells (1000 m). This electricity production covers 6 to 7% of the demand of the island. A partial underground fluid reinjection is operational, since 2015. Exploration by BRGM and EURAFREP began in the 1960s. The Bouillante geothermal field has been the playing field for research, development and innovation of BRGM group, which developed tools to be applied in Bouillante, but also in other overseas territories and abroad. One can mention, inter alia, the successful thermal well stimulation in 1998, the development of exploration methods in geology, fluid geochemistry and geophysics adapted to the overseas specificities, the exploration of other parts of the Bouillante area itself, the realization of tracer tests and the reservoir and well modelling. In 2009, a 50 year-concession, covering a large part of the Bouillante commune territory, was granted to GB. Thanks to these activities, additional field development and production increase are clearly possible, notably in the northern part of the Bouillante Bay. BRGM group has been also able to apply a part of this expertise in Martinique and Dominica islands, in which no power plant exist for the moment, but where several potential geothermal areas have been identified for well drilling.
