Ministry of New and Renewable Energy (MNRE).

• Variable renewable energy sources (VRES).
• Thermal (coal or gas) power plant (TPP).

• Annually, the generator must supply a minimum 51% from VRES and the remainder from TPP.
• The generator also needs to maintain an 80% availability factor without affecting the above criterion. To facilitate this condition, usage of Energy Storage System may be implemented.

• A composite single tariff for renewable energy complemented with thermal energy shall be quoted at the delivery point which shall be at the CTU interconnection point.
• Transmission-related losses and charges from the delivery point shall be borne by the DISCOMs.
• Generators shall access and bear the cost of obtaining open access for supply of power up to CTU/STU interconnection point.
• Tariffs for solar, wind and small hydro power are not indexed with any prices, but tariffs for thermal power are indexed with the price of coal.
• The composite tariff shall be divided into composite fixed charges and composite variable charges by the bidder.
• The bids shall be evaluated for the composite levelised tariff.
• If the bidder quotes a firm composite variable charge for all years of supply, then the bid will be evaluated based on the variable charge proposed and the composite tariff thereof.
• As an alternative to dividing the composite levelised tariff into composite fixed charge and variable charge, the bidder may use normative composite fixed charges and variable charges in the ratio of 70:30.
