The Solar Energy Corporation of India Limited (SECI), operating under the Ministry of New and Renewable Energy, has successfully inaugurated India's largest Battery Energy Storage System (BESS), designed to store solar energy.

Located in Rajnandgaon, Chhattisgarh, this system boasts a capacity of 40 MW/ 120 MWh. Complemented by a 152.325 MWh solar photovoltaic (PV) plant, it offers a dispatchable capacity of 100 MW AC (155.02 MW peak DC).

This initiative aligns with Chhattisgarh's commitment to meet peak energy demands sustainably, as the state will procure the energy, thereby fulfilling its renewable purchase obligations. Prime Minister Narendra Modi officially dedicated the project to the nation through a virtual ceremony.

A key feature of this project is its utilization of bifacial modules, a cutting-edge technology that optimizes energy generation by reflecting ground light, surpassing the output of traditional monofacial modules. This advancement sets a new standard for large-scale renewable energy initiatives, aligning with India's commitment to sustainable development.

Moreover, the project exemplifies strategic land utilization, repurposing 451 acres of previously unused land across 9 villages in Tehsil Dongargarh and Dongargaon, District Rajnandgaon, Chhattisgarh. Through a tripartite agreement involving the Energy Department of the Government of Chhattisgarh, Chhattisgarh State Power Distribution Company Limited (CSPDCL), and SECI, this initiative demonstrates a sustainable approach to energy project development while minimizing environmental impact.

Ensuring power stability and reliability, the project integrates seamlessly into the existing power grid through a 132 kV double-circuit double-string transmission line to Chhattisgarh State Power Transmission Company Limited’s (CSPTCL) Thelkadih substation.

In addition to its environmental benefits, the project is estimated to save tons of carbon dioxide emissions annually, underscoring its contribution to mitigating climate change. Supported by a long-term power purchase agreement with the state electricity distribution company (CSPDCL), the project demonstrates its economic viability and paves the way for future renewable energy endeavors.

Funded by the World Bank and Clean Technology Fund under the Innovation in Solar Power & Hybrid Technologies Project, as well as domestic lending agencies, the project exemplifies collaborative efforts to drive sustainable financial arrangements. This not only makes the project commercially attractive but also showcases India's commitment to global sustainability goals.
