Energy Storage

L&T Construction has commissioned 185 MW of grid-connected solar capacity coupled with a 254 MWh battery energy storage system at Kajra in Bihar’s Lakhisarai district, marking India’s largest commissioned solar-plus-BESS project to date.

While 2025 was marked by an unprecedented 102 GWh of energy storage tenders, 2026 will see projects awarded since mid-2023 finally materialize into commissioned assets, in line with typical project timelines of 18–24 months.

Delta Electronics India will supply 100 units of its made-in-India 1.1 MW bi-directional power conditioning systems to Prostarm’s battery energy storage projects for power utilities, including Bihar State Power Generation Company Ltd and Adani Electricity Mumbai Ltd.

NTPC Renewable Energy Ltd has tendered the engineering, procurement and construction (EPC) package for the development of a 250 MW ground-mounted solar power project integrated with a 50 MW/200 MWh battery energy storage system (BESS) at Sitapur, Uttar Pradesh.

Waaree Energy Storage Solutions has raised INR 1,003 crore to support the development of a 20 GWh lithium-ion cell and battery pack manufacturing facility.

India’s Ministry of Road Transport and Highways (MoRTH) has released draft guidelines for the implementation of a Battery Pack Aadhaar system—an indigenous digital identification and data storage mechanism designed to ensure end-to-end lifecycle traceability of batteries, particularly those used in electric vehicles (EVs).

Bondada Engineering Ltd has received a Letter of Award (LoA) from the Transmission Corp. of Andhra Pradesh Ltd (AP TRANSCO) for the development of a 225 MW/450 MWh standalone battery energy storage system (BESS) project.

Longer-duration storage, safety-driven procurement and Foreign Entity of Concern (FEOC) compliance in the United States are accelerating interest in alternative battery chemistries, even as lithium-ion remains dominant amid rising data center demand and tighter supply chain rules.

Lineage Power will supply and deploy 25,000 advanced lithium-ion battery modules with a capacity of 100 Ah/48V, along with 2,500 high-durability IP55-rated racks. Each rack will be designed to house eight battery modules. These systems are intended to deliver high-efficiency energy storage to support BSNL’s telecom network infrastructure.

With record 40+ GW solar and wind installations (solar: 34.9+ GW, wind: 5.8+GW), 2025 has marked yet another high point in Indian annual renewable capacity additions. The capacity additions have been driven by strong project momentum across all solar segments.
