According to a regulatory filing, this engineering, procurement, and construction (EPC) order marks an extension of the earlier phase of the project. With this addition, the total co-located storage capacity at the Lakhisarai renewable energy site will rise to 495 MWh — making it the largest such project awarded by a state utility in India.

The deployment of a 4-hour BESS alongside intermittent solar generation will facilitate energy time-shifting — enabling surplus clean energy to be stored and dispatched during peak demand periods. The advanced BESS system will feature liquid cooling technology, which ensures higher power density, enhanced safety, and extended operational life.

This initiative aligns with the Government of India’s policy emphasis on co-located renewable energy storage systems and supports Bihar’s Jal-Jeevan-Hariyali Abhiyan (Water, Life, and Greenery Mission). It also contributes to employment generation and long-term energy security in the region.

Earlier, L&T’s Renewables vertical had secured an EPC order for a 275 MW Solar PV project in Gujarat, further strengthening its portfolio of flexible, efficient, and cost-effective clean energy systems.
