Utility Scale Storage

With peak power demand expected to approach 300 GW in the coming years and electricity demand growing at 6–7% annually, India would require nearly 230 GWh of energy storage capacity by 2030 to ensure grid stability, flexibility and reliability—said Bhupinder Singh Bhalla, Former Secretary, MNRE, at the Indian Power & Energy Storage Conference 2025, organised by FICCI.

Juniper Green Energy has successfully commissioned 60 MWh of its 100 MWh merchant battery energy storage system (BESS) in the Bikaner district of Rajasthan. The remaining 40 MWh capacity is expected to be commissioned shortly.

NTPC’s R&D wing NETRA will set up a plasma gasification-based green hydrogen plant on its campus at Greater Noida. The plant will be designed to produce one tonne of green hydrogen per day.

WattPower has sold more than 18 GW of utility-scale string inverters across India over the last two and a half years.

ArcelorMittal has announced three new renewable energy projects in India totaling 1 GW of nominal solar and wind capacity. Upon completion, the projects will double the company’s renewable energy capacity in India to 2 GW and increase its global total to 3.3 GW.

Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.

Researchers at Tokyo University of Science showed that sodium-ion batteries with hard carbon anodes can charge faster than lithium-ion batteries by using a diluted electrode method that reveals sodium insertion is intrinsically quicker than lithium.

Solar Energy Corp. of India Ltd (SECI), on behalf of GRIDCO, has invited proposals for setting up six grid-connected standalone battery energy storage system (BESS) projects with a cumulative storage capacity of 500 MWh (125 MW x 4 hours) in Odisha.

Welsh battery breakthrough uses UK-manufactured anode and cathode materials as well as active materials available through local supply chains. Batri plans to scale up material manufacturing and cell building capability.

Bulgaria’s second standalone energy storage procurement exercise of 2025, worth close to BGN 229 million ($137.2 million), received a lot of interest and there are 30 project proposals included in a reserve list, the government said.
