1) geothermal power station 2) geothermal power plant a thermal power station in which thermal energy is extracted from suitable parts of the earth's crust GRM: n. (1,2) Note: the geothermal energy is converted in electrical energy; the temperature of the geothermal fluid determines its potential application, namely: 20°C to 80°C: space heating, 80°C to 150°C: process heating and/or electricity, over 150°C: electricity generation References: GENthermal generating station GENthermal power station
