Tata Power Company Limited : Tata Power’s Associate Geodynamics, Australia commissions 1 MW Geothermal pilot plant in Australia
Tata Power, India’s largest integrated power utility and leading renewable energy player today announced the successful missioning of 1 MW Geothermal pilot plant in Australia. Geodynamics Ltd., in which Tata Power is a associate participant.
Geodynamics is the industry leader in EGS. Geodynamics has geothermal exploration interests in 3 Australian states including the license for exploring 2000 sq. km of area in the Cooper Basin. Geodynamics tenements in the Cooper Basin contain the hottest granites on earth and are estimated to provide a thermal resource equivalent of 50 billion barrels of oil.
Tata Power intends to have a 20 – 25% contribution from “clean power sources” which will include a mix of Hydro, Solar, Wind, Geothermal and Waste Gas generation. Geothermal energy has been a key focus area for the pany outside India. Tata Power is the only Indian player in geothermal energy and is also implementing a 250 MW geothermal project in Indonesia in partnership with Origin energy and PT Supraco. The Company invested in geothermal energy – both conventional and enhanced geothermal system (EGS) in Geodynamics, an Australian-based geothermal energy pany in 2008.
Speaking on Tata Power’s mitment to clean and green energy, Mr Anil Sardana, Managing Director, Tata Power stated, “The missioning of the 1 MW Geothermal pilot plant is a significant milestone for the project and with this we plan to strengthen our footprint in the international markets. We are mitted to reducing our carbon footprint through clean and renewable energy generation. Our aim is to have 20-25% of our generation portfolio from clean energy.”
Geothermal energy is the natural heat found within the earth, where temperature increases with depth, typically by 10-50 degree Celsius/km. In Enhanced Geothermal Systems (EGS) technology heat is extracted from granites located at a depth of a more than 4000 Metres by circulating water through them in an engineered artificial reservoir. The heated water returns to the surface under pressure and is converted into electricity via a heat exchanger and conventional geothermal power plant.
EGS technology can potentially enable the setting up of base load power plants that are based on naturally heat and thereby making them a clean energy source for the future.
