A state-owned renewable energy subsidiary – NLC India has emerged as the successful bidder for a 50 MW/200 MWh standalone Battery Energy Storage System (BESS) project at Arambag in Hooghly district, West Bengal. The project was awarded through a competitive bidding process initiated by the Department of Power through the state electricity distribution company.
Following the successful completion of the bidding process, the renewable energy subsidiary has received the Letter of Award (LoA), allowing it to proceed with the development of the battery storage project. The proposed installation will have a power capacity of 50 MW and an energy storage capacity of 200 MWh, enabling it to store electricity and discharge it when required by the power system.
The project represents another step towards strengthening energy storage infrastructure in West Bengal. Standalone battery storage systems are increasingly being considered an important part of modern electricity networks, particularly as renewable energy capacity expands and power demand patterns become more dynamic.
The proposed BESS installation at Arambag is expected to support improved energy management and contribute to grid stability. Battery storage systems can help balance fluctuations in electricity supply and demand by storing surplus power during periods of lower demand and releasing it during peak consumption hours. They can also provide flexibility to distribution utilities in managing their electricity requirements.
The project has been awarded under a tariff-based competitive bidding framework, which enables developers to compete for energy infrastructure projects based on specified technical and commercial requirements. Such mechanisms are being used to encourage investment in battery storage and other power sector infrastructure while supporting transparent project allocation.
For the state-owned enterprise, securing the Letter of Award marks a further expansion of its activities in the renewable energy and clean technology sectors. The project also reflects the growing role of public sector undertakings in developing energy storage assets to complement conventional generation and renewable power sources.
As India continues to expand its renewable energy capacity, battery storage infrastructure is expected to play an increasingly important role in maintaining reliable electricity supply. Projects such as the 50 MW/200 MWh installation at Arambag can contribute to improving the flexibility of the power system and supporting the integration of renewable energy into the electricity grid.
