The government is planning large renewable energy projects like the coal-based ultra-mega power project s (UMPPs) through the publicprivate-partnership route. 
The renewable power projects may include any renewable source of generation or a combination of them. The plants are likely to be 1,800 MW in capacity, which can be spread over three areas of 600 MW each, and the power purchase agreements (PPAs) will be for 25 years. 
Industry insiders, however, are skeptical about the idea of such ultra-mega renewable power projects as recent auctions of solar power contracts received tepid response. A tender by the Solar Energy Corporation of India (SECI) for 1,200 MW solar power purchase received bids from SoftBank-backed SB Energy and Chennai-based GRT Jewellers.
