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
