Project Scope and Execution Timeline
The project at NTPC’s Barauni Thermal Power Station involves the supply, civil works, and erection of a 250 MW/1,000 MWh Battery Energy Storage System. The configuration includes 5 MWh DC containers equipped with advanced Battery Management Systems and Thermal Management Systems. The infrastructure will also feature 33 kV panel boards and 220 kV DC and AC cabling connected to a dedicated 220 kV switchyard.
SPML Infra will manage the facility through an 18-month construction phase, transitioning into a long-term 15-year operation and maintenance commitment. This hybrid approach leverages existing thermal assets to facilitate smoother renewable energy integration into India’s power grid.
Strategic Partnership and Technical Strength
To deliver this high-capacity storage solution, SPML Infra is collaborating with Energy Vault (NYSE: NRGV), a global leader in energy storage technologies. This partnership aims to deploy cutting-edge battery solutions tailored for the scale of India's evolving electricity grid. By integrating Energy Vault’s technology, SPML Infra positions itself to address the growing demand for grid stability and frequency regulation.
The order anchors a broader strategic push into energy storage infrastructure, which the company now considers a core pillar of growth. This win strengthens SPML's competitive standing in the emerging battery ecosystem, moving beyond traditional water and power transmission segments.
