The document discusses India's Generation Based Incentive (GBI) scheme for solar power projects. The key points are: 1) The GBI scheme provides incentives to large solar power projects over 1 MW in capacity. 2) The scheme guarantees an overall tariff of Rs. 15 per kWh made up of the state utility tariff plus additional GBI from the government. 3) In states where the utility tariff is lower, GBI makes up the difference to meet the Rs. 15 per kWh target rate.
