| Abstract | We have known for a long time that under Bordeaux there is a medium-temperature water reservoir which could be used as a major thermal source for space heating. The existence of fresh water at some depth under Bordeaux meant that it might be possible to design geothermal projects on the basis of a single well and postpone reinjection for several years. Meriadeck is the fust geothermal operation (GE to have been completed under the conurbation. The well came into operation in October 1982 and is still running in 1994 without problems. Geothermal station of Pessac (GE has been exploited since the first half of 1983. Total energy savings of this two plants are estimated at |
