L&T Renewables Business Wins 116 MW Solar, 241 MWh BESS Project In Bihar

Larsen & Toubro's (L&T) renewables unit recently won a contract to develop a grid-connected solar-plus-storage project in Bihar, it said in statement. The project includes a 116 MWac solar photovoltaic (PV) plant integrated with a 241 MWh battery energy storage system (BESS) in Kajra, Lakhisarai district, the company said in a statement.

The company said that the recent engineering, procurement, and construction order marks an extension of the earlier phase. It explained that the latest project would take the company's total co-located storage capacity of the renewable generation site at Lakhisarai to 495 MWh.

It further added, "The deployment of a 4-hour BESS alongside intermittent solar generation will enable energy time-shifting, allowing surplus clean energy to be stored and dispatched during peak demand periods." 

BESS Technology Used 

Explaining the technology used by the company in the BESS project, it said, "The advanced BESS solution will feature liquid cooling technology, ensuring higher power density, improved safety, and extended operational life. The initiative aligns with the Government of India’s policy push for co-located renewable energy storage systems and supports the Jal-Jeevan-Hariyali Abhiyan (water, life, and greenery mission) in Bihar, while contributing to employment generation and long-term energy security." 

Sharing details about L&T's previous renewable energy project, it added, " The Renewables business vertical had earlier secured an EPC order for a 275 MW Solar PV project in Gujarat, strengthening its portfolio of flexible and cost-effective clean energy systems." 

Previous BESS Projects in Bihar

Earlier this year, Bihar State Power Generation Company Ltd (BSPGCL) awarded its 125 MW/500 MWh battery energy storage system (BESS) project to six bidders. These six winning bidders are Barbrik Projects, Saatvik Green Energy, Kundan Green Energy, Prostarm Info Systems, Hindustan Thermal Project (Hindustan Power), and Suryam International. They secured Bihar's BESS project at a tariff of ₹4.44Lakh/MW/Month.
