SPML Infra Limited, one of India’s leading publicly listed infrastructure development companies, bagged a landmark ₹1,128 crore contract from NTPC Limited to develop a one GWh Battery Energy Storage System (BESS) at the Barauni Thermal Power Station in Bihar. The project marks SPML Infra’s first large-scale grid-scale battery energy storage venture and represents a significant step in India’s clean energy transition.
The project is among the largest single Battery Energy Storage System (BESS) orders awarded in the country, highlighting the growing importance of energy storage in strengthening India’s power infrastructure and renewable energy integration.
Scope of the Battery Energy Storage Project
Under the contract awarded by NTPC, SPML Infra will execute the complete supply, civil works, and erection of a 250 MW/1,000 MWh Battery Energy Storage System. The project scope includes 5 MWh DC containers, Battery Management System (BMS), Thermal Management System (TMS), 33 kV panel boards, 220 kV DC and AC cables, 220 kV switchyard and associated electrical and infrastructure accessories. The project is scheduled for completion within 18 months, followed by a long-term operation and maintenance period of 15 years.
Strengthening Grid Stability and Renewable Integration
The upcoming BESS facility will integrate large-scale battery storage with the existing thermal power infrastructure at NTPC’s Barauni plant. As a result, the system will support peak load management, improve grid stability, and enable smoother integration of renewable energy into the national power network. With India accelerating its renewable energy capacity additions, Battery Energy Storage Systems are rapidly emerging as a critical component for building a stable, flexible, and future-ready electricity grid.
SPML Infra Expands Presence in Energy Storage
Abhinandan Sethi, Managing Director of SPML Infra Limited, said the project represents a defining moment for the company and reflects its strong commitment to the large-scale battery energy storage sector. He stated that energy storage will play a key role in shaping India’s future power ecosystem and added that partnering with NTPC on such a landmark initiative is both an opportunity and a responsibility for the company.
Strategic Push into India’s Clean Energy Infrastructure
The NTPC order further strengthens SPML Infra’s long-term strategy to expand into advanced energy storage infrastructure. The company is developing next-generation battery energy storage solutions in collaboration with its technology partner, Energy Vault, aimed at supporting India’s rapidly growing energy demands and sustainability goals. As reported by electricalmirror.net, with this project win, SPML Infra has significantly strengthened its position in India’s emerging Battery Energy Storage System market, making energy storage a core pillar of its future growth strategy.
