PURPOSE: An ORC(Organic Rankine Cycle) power generation system with geothermal heat is provided to reduce a setup time for charging external devices with electricity. CONSTITUTION: An ORC(Organic Rankine Cycle) power generation system(100) with geothermal heat comprises a geothermal heat supply unit(102), a pre-heater(104), an evaporator(106), a super-heater(108), a turbine(110), a power production unit(112), a condenser(114), an engine cooler(116), a storage tank(118), and a pump(120). The pre-heater heats the liquid that is out of a reference temperature range. The evaporator produces gas using the liquid pre-heated at the reference temperature range. The turbine circulates the gas to the pre-heater again, and converts the heated gas into mechanical energy. The power production unit generates electricity by the turbine. The condenser condenses the liquid supplied from the turbine in a liquid state. The engine cooler recovers coolants from the condenser, and continuously cools the liquid condensed by the condenser. The pump pumps up the condensed liquid to the pre-heater.
