SPML Infra has secured a Rs 11.28 billion contract from NTPC to develop a 1 GWh Battery Energy Storage System (BESS) at NTPC’s Barauni Thermal Power Station in Bihar.

The project, among the largest single BESS orders awarded in India, marks SPML Infra’s entry into the large-scale grid battery energy storage segment. The scope includes design, engineering, supply, civil works, erection and commissioning of a 250 MW/1,000 MWh battery storage system along with associated electrical infrastructure.

The project will be executed over 18 months and will include 15 years of operations and maintenance support. According to the company, the storage system will support peak load management, grid stability and renewable energy integration within the power network.

Commenting on the development, Abhinandan Sethi said the order marks a defining milestone for the company’s expansion into the battery energy storage sector and reflects its long-term focus on supporting India’s future energy infrastructure.

SPML Infra added that the project aligns with its strategic push into energy storage infrastructure in partnership with Energy Vault, aimed at developing large-scale battery storage solutions for the Indian market.
