Southern Gold has developed numerous geothermal power projects in various parts of Australia and Cambodia. The Roxby Geothermal project, located in South Australia, comprises a 260,000PJ Resource. This geothermal power plant covers a total area of about 10,000 square kilometers.
According to the Geothermal Resource, heat flows in the Roxby Geothermal project can help in the future development of an EGS or Engineered Geothermal System in the area. An advantage of the strategic location of the Roxby Geothermal project is that it can straddle the power lines that connect the national grid at Port Augusta to important mines such as the Prominent Hill and Olympic Dam. These power lines have capacities of 275Kv and 132Kv.
According to the design and plan of the Roxby Geothermal project, developed by Southern Gold, a heat exchanger must be constructed right above the source of heat. The heat exchanger can be placed within a sedimentary rock and can be installed underground. Thus, the Engineering Geothermal System can be utilized for the production of geothermal fluids, which in turn are used for the generation of electricity.
