750 MW Rewa Ultra Mega Solar Power Plant Manu Srivastava Why 750 MW REWA project makes for a pertinent case to study ? India Achieved Grid Parity with Rewa Project. Project became the tipping point for solar power in India due to its innovative structuring. Solar Power Tariffs showed a historical decline from 7 US ¢/unit to 4.5 US ¢ /unit The Project has been acknowledged as a model project by Government of India. Many of its features have been included in the Standard Bidding Guidelines for solar projects of Government of India.
