India’s energy storage sector has reached a significant milestone with around 7.5 GWh of commissioned storage capacity and more than 140 GWh of projects currently under construction, awarded, or under tendering, highlighting the country’s accelerating shift towards a flexible and resilient clean energy grid. The update was shared by Shri Shripad Yesso Naik, Hon’ble Minister of State for Power and New & Renewable Energy, during the 12th India Energy Storage Week (IESW) 2026 in New Delhi.
“India has commissioned around 7.5 gigawatt-hours of storage capacity, while more than 140 gigawatt-hours is under construction, awarded, or under tendering. But if we are to build a truly flexible grid, deployment must accelerate further because the requirement is no longer measured only in gigawatts. It is measured in our ability to respond instantly to changing system conditions,” said Shri Shripad Yesso Naik, Hon’ble Minister of State for Power and New & Renewable Energy, at IESW 2026.
He further referenced a recent paper by the Economics Advisory Council to the Prime Minister, titled “The Duck and the Camel,” which demonstrates that the Indian grid is no longer constrained only by generation capacity; it is increasingly constrained by timing and flexibility.
In the three-day, power-packed event, IESW 2026, organised by India Energy Storage Alliance (IESA), is expected to bring together more than 10,000 visitors, 1,000 delegates, 200+ exhibitors, and over 100 government officials for over 50 conference sessions and five country pavilions. Event highlights include panels on gigafactories, supply chain resilience, battery chemistries, recycling, urban mining, and a dedicated track for women’s leadership in energy.
Debmalya Sen, President of IESA, said, “India Energy Storage Week continues to set the benchmark for uniting policymakers, innovators, and industry leaders. This year’s focus on manufacturing, supply chain, and recycling is pivotal for India’s ambition to become a global hub for advanced energy storage technologies.”
“Battery energy storage systems are no longer simply backup systems. They are becoming flexibility assets. They absorb surplus renewable energy, reduce curtailment, support frequency regulation, reduce expensive evening ramping, defer transmission investments, improve grid resilience, and make renewable energy truly dispatchable. In simple terms, storage converts intermittent renewable energy into dependable renewable energy. We have introduced viability gap funding for standalone BESS, support through the Power System Development Fund, waiver of ISTS charges, integration of storage with renewable energy projects, recognition of BESS under the infrastructure sector, and the 50 gigawatt-hour Advanced Chemistry Cell Production Linked Incentive scheme, including dedicated capacity for stationary storage,” the minister added.
“India’s opportunity extends far beyond deployment. We must become a global manufacturing hub, not only for battery cells, but for the complete ecosystem comprising battery management systems, energy management systems, power conversion systems, thermal management, fire safety systems, battery recycling, power electronics, and advanced software that will increasingly become the intelligence behind the future grid. This is where India’s engineering capability, digital strength, and manufacturing ambition can converge. While batteries are ideally suited for short-duration balancing and grid flexibility, green hydrogen will play an increasingly important role in long-duration storage and industrial decarbonization. Together, these technologies will strengthen India’s energy security while reducing dependence on imported fossil fuel,” the Minister said.
Vinayak Walimbe, Managing Director, Customized Energy Solutions, said, “The conversations and collaborations at IESW 2026 are accelerating the development of a resilient, sustainable, and inclusive energy storage value chain. With strong government support and private sector participation, India is poised to lead the world in clean energy innovation and deployment.”
As IESW 2026 continues, India’s energy storage sector stands at the forefront of the country’s clean energy revolution, powered by innovation, partnership, and a shared commitment to Atmanirbhar and Viksit Bharat.
