SPML Infra Limited, (NSE:SPMLINFRA, BSE:500402), a leading publicly listed infrastructure development company in India, has secured a landmark ₹1,128 crore (USD 120 million) contract to develop a 1 GWh Battery Energy Storage System (BESS) at NTPC Limited’s Barauni Thermal Power Station in Bihar, marking the first large-scale grid Battery Energy Storage System project for SPML Infra.
Awarded by the National Thermal Power Corporation (NTPC), this project ranks among the largest single BESS orders awarded in India, signalling a defining moment not just for SPML Infra, but for the country’s clean energy ambitions.
The scope of work included design, engineering, supply, civil works, erection and commissioning of 250 MW/1,000 MWh Battery Energy Storage System (BESS) comprising 5 MWh DC containers with Battery Management System (BMS) and Thermal Management System (TMS), 33 kV panel boards, 220 kV DC & AC cables, 220 kV switchyard and all associated accessories. The project will be executed over an 18-months period followed by a 15 years of operation and maintenance.
The project will seamlessly integrate large-scale battery storage with existing thermal power infrastructure enabling peak load management, grid stability, and efficient integration of renewable power. As India’s power networks evolve, Battery Energy Storage Systems are fast becoming the backbone of a stable, responsive, and future-ready electricity grid.
Abhinandan Sethi, Managing Director, SPML Infra Limited, said“This order marks a defining moment for SPML Infra, a firm commitment to the large-scale battery energy storage sector. Energy storage will define how India powers its future, and we intend to be architects of that transformation. Partnering with NTPC on this landmark project is both a privilege and a responsibility we embrace fully. We are here to build the grid India needs — flexible, stable, and built for scale.”
This anchors SPML Infra’s broader strategic push into energy storage infrastructure, advancing its commitment to developing cutting-edge battery energy storage solutions in collaboration with its technology partner, Energy Vault (NYSE: NRGV), tailored to meet India’s scale and ambition. Energy storage is no longer a future priority for SPML Infra; it is a core pillar of growth today. With this order, SPML Infra strengthens its position in India’s emerging battery energy storage ecosystem.
