Government Initiatives and Policy Measures


The Ministry of New and Renewable Energy (MNRE) has expanded its Approved List of Models and Manufacturers (ALMM), adding 2,674 MW of new solar module capacity. The ALMM now boasts a cumulative capacity of 50,675 MW, with significant contributions from several manufacturers. These additions are crucial in supporting the expanding solar infrastructure and the integration of energy storage systems.


Auction Success: UPNEDA's Solar Projects


The Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA) recently conducted a successful auction for 500 MW of grid-connected rooftop solar projects under the RESCO model, with competitive tariffs discovered across two categories.


Category 1 (25 kW to 200 kW): ₹4.9 (~$0.0587)/kWh


Category 2 (200 kW to 2,000 kW): ₹4.85 (~$0.0581)/kWh


Renewable Energy Integration and Grid Stability


By March 2024, renewable sources contributed 28.9% of India’s electricity capacity. The rapid addition of intermittent renewable energy sources like solar and wind has significantly impacted grid stability. Policy measures such as the deviation settlement mechanism, grid connectivity regulations, and ancillary services regulations are being implemented to ensure efficient renewable integration and grid stability, driving the demand for utility-scale energy storage.


  • Chhattisgarh: Leads in BESS capacity, representing 54.8% of the cumulative installed capacity.

  • Rajasthan: Showing significant growth in standalone BESS capacity due to favorable provisions in the state’s renewable energy policy and annual energy storage obligations through FY30.


Pumped Hydro Storage


India's operational pumped hydro storage capacity stood at 3.3 GW by March 2024, with major installations in Telangana and West Bengal, which account for nearly 76% of the country’s operating capacity.


Energy Storage Market Trajectory


Since the inception of small pilot projects in 2013, India’s cumulative energy storage capacity has now reached 219.1 MWh, with solar PV and BESS systems comprising 90.6% of the installed capacity. In the first quarter of 2024 alone, 120 MWh/40 MW of BESS was added.


57 GW for energy storage projects were floated in tenders, and 11.5 GW of projects were auctioned by March 2024. Tenders for standalone and renewable projects with energy storage totaled 7.4 GW in Q1 2024. These developments underscore India's rapid advancement in energy storage, supported by robust policy frameworks and strategic investments.
