The Solar Energy Corporation of India Limited (SECI) has commissioned India’s largest Battery Energy Storage System (BESS) with an installed capacity of 152.32 MWh and dispatchable capacity of 100 MW AC (155.02 MWp DC) solar photovoltaic plant with 40 MW/120 MWh BESS in Rajnandgaon, Chhattisgarh.
The project has deployed bifacial modules, which also reflect the light from the ground to generate more electricity than monofacial modules, hence setting a new standard for large-scale renewable energy projects. The project ensures overall power stability and reliability by ensuring an efficient evacuation of power through a 132 kV double circuit double string transmission line to Chhattisgarh State Power Transmission Company Limited’s 220/132 kV Thelkadih substation, facilitating seamless integration into the existing power grid. The project has been constructed with the funding from the World Bank and Clean Technology Fund under Innovation in Solar Power & Hybrid Technologies Project as well as leveraged financing from the domestic lending agencies.
