Gujarat set to the be first region in India to use geothermal power
Gujarat is set to be the first state in India to generate electricity using geothermal energy with the 20 kW pilot-scale power plant in Dholera which will start operations in April.
Gujarat is set to become the first state in India to use geothermal energy to produce electricity. The power plant being set up at Dholera will become operational in April.
“India’s first geothermal power plant will start operating on a pilot scale in April in Dholera, and it will produce 20 kW of electricity. Dholera was chosen for the plant as immense heat has been found under the earth in the form of hot springs,” the Centre of Excellence for Geothermal Energy (CEGE), set up by the state government at Pandit Deendayal Petroleum University (PDPU) said.
CEGE head Prof. Anirbid Sircar said that not much work on geothermal energy has been undertaken in the country. “We are the first to initiate an attempt to generate electricity with the help of geothermal energy,” he said.
The release said that two geothermal bore wells were drilled at Dholera where water temperature was found to be between 47-50 degree Celsius. Hot water produced from the wells would be used for generating power using an Organic Rankine Cycle (ORC) technique.
“In 2016, CEGE had set up the first-of-its-kind geothermal space heating and cooling plant at Dholera. This will now be integrated with ORC to generate heat to run the turbine that drives a generator, which in turn will produce electricity,” it said further.
Manan Shah, scientist at CEGE, said that the cost of the pilot project was around Rs 1 crore. “The initial investment in geothermal energy is 20-25 per cent higher compared to conventional power plant, but the additional cost is recovered in three years. Moreover, geothermal energy system has a longer life,” he said.
CEGE said that work will start for similar projects at Unai and Gandhinagar this year, where geothermal energy potential has also been found.
The geothermal energy potential in the country is estimated at more than 10,000 MW, but it has remained untapped so far.
