The geothermal energy generator system is a closed loop, binary cycle power generating plant that utilizes heat from a geothermal heat well to convert a working medium of gas, e.g., CO2, and liquid, e.g., H2O, into steam to produce energy. The geothermal energy generator system includes a medium preparation subsystem that cools recycled working medium to a predetermined temperature. The cooled working medium is selectively fed to a carbonation subsystem permitting the gas to dissolve into the liquid at the predetermined temperature. The carbonated working medium flows through a heat exchange pipe section in the geothermal heat well to produce high pressure steam and gas or hot medium. The hot medium passes through a power generating subsystem containing a primary power generating assembly, a secondary power generating assembly, and a tertiary power generating assembly arranged in series to maximize usage of heat from the working medium and produce energy.
