Geothermal Power -
Geothermal energy is the natural heat generated within the earth due to radioactive activities.
Among these provinces, Maharashtra shares
- West Coast (Konkan) geothermal province
- Narmada-Tapi Garben geothermal province
- Godavari valley geothermal province.
Some of the identified sites are Tapi basin, Jalgaon, Dhule and Salbardi hot spring in Maharashtra. Nearly 340 hot springs have been identified in the country having temperatures in the range of 60-120 0C.
A pilotpower plant of 5 kW based on close loop organic Rankine cycle was installed in Manikaran. Mostof the geothermal sites are in low and moderate temperature range.
The initial high cost and negligible low running cost make them commercially viable in the long run with a payback period of around 8 years. Based on the tried and tested technologies abroad, geothermal energy needs to be utilized specially for socio-economic development of the backward hilly areas. With suitable governmental support, private investment can be an attractive proposition.
