SPML Infra Ltd has secured a landmark Rs.1,128-crore contract to develop a 1 GWh Battery Energy Storage System (BESS) at NTPC Ltd’s Barauni thermal power station in Bihar.
This is the first large-scale grid-tied BESS project for SPML Infra, the company said in a release.
This project ranks among the largest single BESS orders awarded in India, signaling a defining moment not just for SPML Infra, but for the country’s clean energy ambitions, the release noted.
Scope of work
The scope of work included supply, civil works, and erection of 250 MW/1,000 MWh BESS comprising 5 MWh DC containers with battery management system (BMS) and thermal management system (TMS), 33kV panel boards, 220kV DC & AC cables, 220kV switchyard and all associated accessories. The project will be executed over an 18-months period followed by a 15 years of operations & maintenance (O&M).
Towards grid stability
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, the release said.
Defining moment
According to Abhinandan Sethi, Managing Director, SPML Infra Ltd, “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.
Core pillar
This win anchors SPML Infra’s broader strategic push into energy storage infrastructure, advancing its commitment to developing cutting-edge battery energy storage solutions along with its technology provider, Energy Vault.
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, the release added.
