Overview of Geothermal Resources and Exploration Activity in Victoria

Victoria currently derives most of its electricity generation from brown coal but is keen to diverse towards lower emission energy sources. Geothermal energy offers the possibility of base load power generation plus direct use thermal applications. Legislation for geothermal resource security was passed in 2005. In 2006 and 2008 two rounds of competitive tendering resulting in about two thirds of the State being placed under exploration by seven different companies. They have pledged to spend close to $370 million over the next five years in the quest to find and develop geothermal resources. Legacy data from petroleum exploration suggests potential for Hot Sedimentary Aquifer (HSA) plays in basins along the onshore margin of Victoria. Elsewhere the geology may support Engineered Geothermal Systems (EGS) plays in the abundant Palaeozoic granites. Magmatic plays may also exist in association with a major episode of recent basaltic volcanism. Governments, Universities and exploration companies are currently collecting basic geothermal data such as heatflow measurements and thermal conductivities to better characterise the potential of geothermal systems in Victoria. A number of Inferred Resources have been declared but deep drilling to appraise these is awaiting funding opportunities.
