In a major stride for grid-scale energy storage, Larsen & Toubro’s Renewables business has clinched a Significant EPC contract to deploy a 241 MWh Battery Energy Storage System (BESS) alongside a 116 MWac solar PV plant in Kajra, Lakhisarai district, Bihar.
This development extends the total storage capacity at the site to 495 MWh, making it India’s largest co-located solar + storage installation awarded by a state utility. The project is a notable example of India’s transition toward hybrid renewable infrastructure—integrating intermittent solar generation with long-duration battery storage to enhance dispatchability.
The integrated 4-hour BESS is engineered for energy time-shifting, enabling surplus solar energy to be stored during the day and released during peak demand hours. Crucially, the system will utilize liquid cooling technology, known for its superior thermal efficiency, higher power density, improved operational safety, and extended lifecycle performance.
The project aligns with the Indian government’s policy thrust on co-located energy storage and supports Bihar’s Jal-Jeevan-Hariyali mission, aimed at fostering water conservation, sustainability, and energy security.
Beyond grid benefits, the initiative is set to stimulate local employment and build robust storage deployment expertise at the state level. L&T’s growing BESS portfolio also includes a 275 MW solar EPC project in Gujarat, reinforcing its role in deploying next-gen, flexible clean energy systems.
Larsen & Toubro, a USD 30 billion Indian EPC and manufacturing major, continues to expand its footprint in integrated renewable and storage solutions through advanced technology adoption and strong project execution capabilities.
