India’s power sector is entering a phase where merely adding new electricity generation capacity will not be sufficient. With the increasing share of renewable power, it is also necessary to store electricity generated at different times and use it as needed. This shift is making energy storage an important part of the power system.
Let us understand India’s growing energy storage needs in detail and see what kind of opportunities this change can create for investors.
What’s Happening?
According to CareEdge Ratings, India may need more than Rs 4 lakh crore of storage-related capex by FY32 to meet its energy storage requirements. The major reason for this is the growing need to effectively integrate renewable power into the electricity system.
As per the report, India’s energy storage requirement could reach approximately 411 GWh by FY32. In comparison, operational storage capacity was around 54 GWh as of June 2026.
The report says that the challenge for the power sector is now shifting from merely increasing generation capacity to effectively integrating the growing renewable capacity into the grid. Storage can help manage electricity generated from variable renewable sources more efficiently.
Why Is the Need for Storage Increasing with Renewable Power?
The share of non-fossil sources in India’s installed power generation capacity is around 50%, but their contribution to actual electricity production is approximately 29%. This gap shows that merely adding renewable capacity is not sufficient; supporting infrastructure is also necessary to make the electricity generated from these sources available according to time and demand.
According to the report, the expansion of renewable power can create the need for new investments across the entire power system rather than completely replacing traditional power sources immediately. The impact of this change is visible in standalone storage-based tenders. Such tenders rose from 7 GW in FY25 to around 21 GW in FY26. This reflects the growing activity in the energy storage segment.
Growing Role of BESS, PSP and Transmission
CareEdge Ratings views Battery Energy Storage Systems, or BESS, and Pumped Storage Plants, or PSPs, as technologies that can support each other in India’s power transition. As renewable generation increases, both storage models can play an important role in keeping the power system balanced.
Along with this, expansion of the transmission network will also be necessary because storage and new generation capacity can be effective only when electricity can be delivered to different parts of the grid. The report estimates approximately Rs 5.19 lakh crore of capex in the transmission sector during FY27 to FY31.
However, execution challenges such as right-of-way issues, forest clearances and coordination remain in this sector. Despite this, the stable cash flow profile of operational transmission assets and long concession tenures support the credit profile of the sector.
What Does This Mean for Investors?
The investment opportunity arising from the energy transition is not limited to renewable generation. The growing need for storage can increase the role of segments such as BESS and PSP, while the need for large transmission capex also makes grid infrastructure an important part of this change.
Along with this, CareEdge Ratings says that coal-based thermal power is also entering a multi-year phase of better credit stability and new investment relevance. Well-contracted thermal power assets can remain important in meeting growing electricity demand and providing the necessary flexibility to integrate renewable capacity.
Storage, transmission and flexible generation are interconnected parts of the power system. For investors, it will be important to look at this entire ecosystem and the related execution challenges together while understanding the opportunities.
What’s Next?
The next phase of India’s power sector will depend on how effectively the growing renewable capacity is integrated into the grid. As variable renewable power increases, the ability to store electricity, make it available when needed and deliver it to different regions will become more important.
CareEdge Ratings’ report indicates that the expansion of energy storage and transmission will move alongside renewable growth, while flexible thermal generation will also continue to play a role in maintaining system balance.
The challenge ahead will not only be to create new capacity, but also to establish effective coordination between storage, grid and generation so that both growing electricity demand and renewable integration can be managed. This coordination will determine how effectively India’s power transition moves forward.
