Details of the CEA advisory
"To facilitate the large-scale integration of renewable energy, the CEA has recommended that renewable energy implementing agencies and state utilities include co-located ESSs in upcoming solar tenders.
The advisory specifies that storage capacity equivalent to 10 percent of the installed solar project capacity, with a minimum duration of two hours, should be mandated. Further, the tender documents should include a clear compliance mechanism to ensure the availability of stored energy during non-solar hours.
This approach is expected to improve grid reliability during peak demand periods while also optimising the utilisation of renewable energy sources. Additionally, distribution licensees could consider requiring rooftop solar installations to include a minimum of two-hour energy storage. This would not only enhance supply reliability for consumers but also reduce the burden on distribution networks by curbing excess power injection during peak solar generation hours.
ESSs can operate in two distinct modes. In single-cycle operation, they can charge exclusively from the co-located solar power plant and discharge during evening hours. In double-cycle operation, they can charge from both the co-located solar plant and the grid during periods of low demand, allowing for discharge during peak hours when solar generation is unavailable."

Energetica Article:
As per the National Electricity Plan published by the Central Electricity Authority, in order to integrate the 364 GW of solar and 121 GW of wind capacity by 2031-32, India would require 73.93 GW/411.4 GWh of storage capacity - 26.69 GW/175.18 GWh from Pumped Storage Projects (PSP) and 47.24 GW/236.22 GWh from Battery Energy Storage System (BESS).
The current installed capacity of ESS as of December 31, 2024 is 4.86 GW which includes 4.75 GW of PSP and 0.11 GW of BESS projects.
