India's largest Solar and Battery Energy project executed by Tata Power

India’s leading EPC (Engineering, Procurement and Construction) solar company, Tata Power Solar Systems Limited (TPSSL), has successfully commissioned India’s largest Solar and Battery Energy Storage Systems (BESS) project at Rajnandgaon in Chhattisgarh. The project comprises a 100MW Solar Photovoltaic project and a 120 MWh Battery Energy Storage System (BESS).

The project has been constructed with funding from the World Bank and Clean Technology Fund under the Innovation in Solar Power & Hybrid Technologies Project and loans from domestic lending agencies.

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

India has set a target to achieve net zero carbon emission by 2070.

Battery Energy Storage System of SECI

• In 2021, Tata Power Solar Systems Limited (TPSSL)  company won the Solar Energy Corporation India Limited (SECI) project tender to construct the Battery Energy Storage System in 451 acres of wasteland in Dongargarh and Dongargaon Tehsil of Rajnandgaon district of Chhattisgarh.  
• Tata Power Solar Systems Limited was responsible for the project's design, engineering, construction, erection, testing and commissioning. 
• The Chhattisgarh government will buy the Power produced by the SECI plant.
• The project has deployed bifacial modules. Unlike the conventional solar modules, which produce electricity from only one side of the panel, the bifacial modules produce power from both sides of the solar panel. 
• The bifacial modules deployed at the Rajnandgaon also use the reflected solar light from the ground. This has increased the efficiency of solar panels and generates more electricity.,

What is a Solar  Battery Energy Storage system?

One drawback of solar power generation is that power can only be generated when there is adequate sunlight. This means that at night, there will be no power production. To solve this problem, the energy generated by the sun in daylight is stored in the battery. 

At night, this stored power is supplied to the consumers, ensuring an uninterrupted supply of electricity to the consumers.
