SPML Infra Limited has announced that it has secured a landmark ₹1,128 crore contract from NTPC Limited for the development of a large-scale Battery Energy Storage System (BESS) project at the Barauni Thermal Power Station in Bihar.
The project marks SPML Infra’s entry into utility-scale battery energy storage and is among the largest single BESS orders awarded in India. The development is seen as a significant step in strengthening India’s clean energy infrastructure and grid stability initiatives.
The scope of work includes supply, civil works, and erection of a 250 MW/1,000 MWh Battery Energy Storage System comprising 5 MWh DC battery containers integrated with Battery Management Systems (BMS) and Thermal Management Systems (TMS). The contract also covers installation of 33 kV panel boards, 220 kV DC and AC cables, a 220 kV switchyard, and associated infrastructure.
The project is scheduled to be executed over 18 months, followed by a 15-year operation and maintenance period.
The battery energy storage system will be integrated with the existing thermal power infrastructure at NTPC’s Barauni Thermal Power Station to support peak load management, improve grid stability, and facilitate efficient integration of renewable energy into the power network.
