Flash Steam Plant

When thegeothermal energyis available at

150C and abovetemperature, thefluids can be useddirectly to generate

electricity.

India's first geothermal plant to be set upin Andhra Pradesh

India's first geothermal plant is expected to come up by2012

initial capacity of 25 mega watt (MW)

Situated in the Khammam district of Andhra Pradesh

(AP) It will be set up by a company incubated by the Indian

Institute of Technology (IIT), Bombay

per unit cost of electricity would be cheaper and more

affordable than electricity rates from other non-conventional energy sources
