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

For section 16 (2) of the Act , the following criteria are prescribed— 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; 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). the geothermal production is for a commercial or industrial purpose.

• (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.
