Grid-Scale Battery Storage, Costs, Value, and Regulatory Framework in India

Jointly organised by Prayas (Energy Group) and Lawrence Berkeley National Laboratory (LBNL)

Date and time: Wednesday, 8 July 2020 | 10 AM

The webinar, attended by over 250 people, discussed the Lawrence Berkeley National Laboratory (LBNL) and Prayas (Energy Group)'s collaborative research on estimating the costs of grid-scale battery storage in India, the value that storage could add to the Indian grid, and the regulatory and policy framework. The webinar focused on our recent report that shows that, in India, the capital costs of stand-alone (4-hour) grid-scale battery storage projects would be $203/kWh in 2020 dropping to $103/kWh by 2030. For co-located storage systems with solar PV, tariff adder for storing 25% of PV energy is estimated to be Rs. 1.44/kWh in 2020, dropping to Rs. 0.83/kWh in 2030. These prices make PV plus storage systems competitive with new generation assets operating at low capacity factors and could disrupt power sector planning. The webinar also discussed the capacity and energy arbitrage value of energy storage in India, as well as regulatory and policy framework.

Presenters: Dr. Nikit Abhyankar (LBNL), Shruti Deorah (LBNL), Ashwin Gambhir (Prayas Energy Group)
Opening remarks by Dr. S.K.Chatterjee, Chief (Regulatory Affairs), CERC
Panelists: Dr. Y. B. Reddy, Additional General Manager, Solar Energy Corporation of India (SECI), Dr. Rahul Walawalkar, President, India Energy Storage Alliance (IESA), and Mr. Deepak Gupta, Vice President, ReNew Power
