GEOTHERMAL ENERGY REGULATION 2022 - REG 4

4 Deciding large-scale geothermal production—Act, s 16

For section 16 (2) of the Act , the following criteria are prescribed—

(a) the total amount of thermal power produced from all geothermal wells measured at the wellhead is 5 megawatts thermal (MW th) or more when the temperature is 0°C and the atmospheric pressure is 1 atm;

Example of measurement of thermal power—

For a geothermal well that produces 50 tonnes an hour of geothermal fluid with specific enthalpy of 900 kilojoules a kilogram, the total amount of thermal power produced from the well measured at the wellhead is 12.5 MW th (above 0°C).

(b) the geothermal production is for a commercial or industrial purpose.
