L&T Bags EPC Order for Solar-Battery Project in Bihar

05 Aug 2025 CW Team

Larsen & Toubro (L&T) announced that its renewables business vertical has secured an engineering, procurement and construction (EPC) contract to develop a 116 MW AC grid-connected solar PV plant integrated with a 241 MWh battery energy storage system (BESS). The project will be executed at Kajra in Lakhisarai district, Bihar.

This latest contract represents an expansion of an earlier phase at the site, bringing the total co-located battery storage capacity to 495 MWh—making it the largest such project awarded by a state utility in India.

The 4-hour BESS will allow surplus solar energy to be stored and released during peak electricity demand periods, facilitating energy time-shifting and improving grid reliability. The system will be equipped with liquid cooling technology, which enhances power density, safety, and the operational lifespan of the batteries.

L&T noted that this award builds on its previous win of a 275 MW solar PV project in Gujarat, further strengthening its clean energy portfolio with flexible and efficient renewable solutions.
