Hindustan Power, led by Ratul Puri, has secured a significant energy infrastructure project in Bihar aimed at boosting the state’s renewable energy integration and grid stability. The Bihar State Power Generation Company Limited (BSPGCL) has issued a Letter of Intent (LOI) to the company for a 120 megawatt-hour (MWh) standalone Battery Energy Storage System (BESS), to be installed at three strategic substations across the state.
The awarded project will see 40 MWh of storage capacity developed at each of the following substations: Bhagalpur, Udakishanganj, and Sitamarhi. The initiative is being undertaken under a Tariff-Based Competitive Bidding (TBCB) model and will follow a BOOT (Build, Own, Operate, Transfer) implementation structure.
Hindustan Power is expected to commission the full 120 MWh capacity within 18 months of the effective date of the Battery Energy Storage Purchase Agreement (BESPA).
This project forms a key part of the Ministry of New and Renewable Energy’s larger 500 MWh battery energy storage plan for Bihar. Once operational, it will play a crucial role in ensuring a more stable and reliable power supply, particularly during peak demand periods, by storing surplus renewable energy and feeding it back into the grid when needed.
Speaking on the development, Ratul Puri, Chairman of Hindustan Power, remarked, “We are pleased to join hands with the Government of Bihar on this project, which aims to create a more flexible, sustainable, and consumer-centric power infrastructure in the state. This partnership reflects our commitment to technological innovation and environmental responsibility.”
The new BESS installations are expected to support both state-level clean energy goals and national objectives under the National Energy Storage Mission. By enhancing grid flexibility and enabling better integration of solar and other renewables, the project aligns with India’s broader energy transition ambitions.
