India’s Largest Solar And Battery Energy Storage Project

Tata Power Solar Systems Limited (TPSSL), an integrated solar company in India and a wholly owned subsidiary of Tata Power Renewable Energy Limited (TPREL), has successfully commissioned the country’s largest Solar and Battery Energy Storage Systems (BESS) project that comprises an 100-MW solar photovoltaic (PV) project coupled with an 120-MWh Utility Scale BESS, at Rajnandgaon in Chhattisgarh.

TPSSL got the project on an engineering, procurement, and construction (EPC) basis from the Solar Energy Corporation of India Ltd. (SECI) in December 2021. The order scope included engineering, design, supply, construction, erection, testing, operations and maintenance, and commissioning of the projects.

The project faced various challenges such as unsuitable full hard rock soil conditions and a remote work location, but the project was still completed in the stipulated time frame. Bifacial Mono Crystalline panel technology was used for 239,685 modules in the project.

“The successful commissioning of the largest solar and battery storage project for SECI, reflects the technical expertise and project execution skills of Tata Power Solar,” said Deepesh Nanda, chief executive officer and managing director of Tata Power Renewable Energy Limited. “This will ensure round-the-clock green energy and accelerate the renewable energy transition through innovative solutions.”

The project is expected to generate an estimated 243.53 million units of energy annually and reduce carbon footprint of 5.37 million tons (4.87 million tonnes) in 25 years, contributing significantly to India’s renewable energy goals.

“We are committed to leverage the latest technology in the renewable energy segment and this project supports the country’s energy transition vision,” said Shri R. P. Gupta, IAS, chair, and MD of SECI. “The project has been delivered on time by Tata Power Solar that will help in providing 24/7 renewable power.”

The company’s solar EPC portfolio includes more than 12.8 GWp of ground-mount utility-scale and more than 2 GW of rooftop and distributed ground-mounted systems.
