NEW DELHI: India needs investments of over $250 billion for development of the power sector in the next three years, says a report.

"Total investment of over $250 billion is required for development of the power system during the 12th plan," Integrated Research and Action for Development said in its report.

This will give an ample opportunity for investors, developers, power equipment manufacturers in developing power projects and associated transmission infrastructure, it said.

During the 12th plan period (2012-17), India plans to add 88,537 MW capacity, out of which 69,280 MW will come from coal.

The government has planned additional renewable energy capacity addition of around 30,000 MW (5,000 MW wind, 10,000 MW solar and 2,100 small hydro).

Currently, India's installed generation capacity, from all sources of energy, is close to 2, 50,000 MW.

"It is estimated that around 25,000 MW capacities is being sub-optimally utilised because of inadequate availability of domestic coal," the report observed.
