India's Largest Solar-Powered BESS Commissioned by SECI in Chhattisgarh

India's Largest Solar-Powered BESS Commissioned by SECI in Chhattisgarh
The Solar Energy Corporation of India Limited (SECI), a part of the Ministry of New and Renewable Energy, has recently launched India's most extensive Battery Energy Storage System (BESS) in Rajnandgaon, Chhattisgarh. This cutting-edge system is tailored to store solar energy and has a remarkable capacity of 40 MW/ 120 MWh. Accompanied by a solar photovoltaic (PV) plant with a capacity of 152.325 MWh, it provides a dispatchable capacity of 100 MW AC (155.02 MW peak DC).
This endeavor is in line with Chhattisgarh's dedication to meet peak energy requirements sustainably, as the state will acquire the energy, thus fulfilling its obligations towards renewable purchases. Prime Minister Narendra Modi formally inaugurated the project for the nation via a virtual ceremony.
An essential aspect of this project is its incorporation of bifacial modules, an advanced technology that enhances energy production by capturing ground-reflected light, surpassing the performance of conventional monofacial modules. This innovation establishes a fresh benchmark for large-scale renewable energy projects in harmony with India's dedication 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.
To guarantee power stability and dependability, the project seamlessly integrates into the current power grid via a 132 kV double-circuit double-string transmission line connected to the Thelkadih substation of Chhattisgarh State Power Transmission Company Limited (CSPTCL).
Apart from its environmental advantages, the project is projected to reduce tons of carbon dioxide emissions annually, highlighting its role in combating climate change. With backing from a long-term power purchase agreement with the state electricity distribution company (CSPDCL), the project showcases its economic feasibility and lays the groundwork for forthcoming renewable energy initiatives.
Supported by the World Bank and Clean Technology Fund through the Innovation in Solar Power & Hybrid Technologies Project, alongside contributions from domestic lending agencies, the project illustrates cooperative endeavors aimed at fostering sustainable financial structures. This not only enhances the project's commercial appeal but also demonstrates India's dedication to global sustainability objectives.
