Karnataka to Pioneer Solar Battery Energy Storage Systems in Pavagada and Kalaburagi

Karnataka Renewable Energy Development Limited (KREDL) is launching solar Battery Energy Storage Systems (BESS) in Pavagada and Kalaburagi, enhancing the efficiency and use of solar energy. Learn how this initiative will transform Karnataka's renewable energy landscape.

In a significant move to enhance the efficiency and sustainability of solar energy, Karnataka Renewable Energy Development Limited (KREDL) is set to install solar Battery Energy Storage Systems (BESS) in Pavagada and Kalaburagi. This innovative approach seeks to ensure that solar energy, an intermittent resource, can be stored and utilized more effectively, particularly during peak demand times. The pilot project in Pavagada Solar Park, Tumakuru district, is expected to be commissioned soon, marking a new chapter in Karnataka’s renewable energy landscape.

Pilot Project at Pavagada Solar Park

The initial phase of the project will take place at the Pavagada Solar Park, where a 2-megawatt (MW) solar photovoltaic (PV) plant will be paired with a 2 MW/4.5 MW/h battery storage system. With an investment of ₹36 crore, this pilot initiative is designed to store solar energy generated during the day for use in the evening, thereby reducing wastage and ensuring a more reliable power supply. Nsure Reliable Power Solutions Private Limited was awarded the tender for this project in 2023, and the major equipment has already been delivered, with civil works in progress.

How Does Solar BESS Work?

Solar energy is most abundantly generated during daylight hours, but the demand for electricity often peaks in the evening. This creates a mismatch in supply and demand. Battery Energy Storage Systems (BESS) resolve this issue by storing excess solar energy generated during the day and releasing it when needed. According to KREDL, 30-50% of the energy generated by the plant will be stored and then supplied to the grid during high-demand periods. This ensures a steady supply of clean energy, even after the sun sets.

Kalaburagi Project

Following the pilot project, KREDL plans to set up a larger-scale solar PV plant with BESS in Kalaburagi. The plant will have a solar generation capacity of 100 MW, paired with a 100/130 MW/h battery storage system. This ambitious project, with an estimated cost of ₹500 crore, is currently in the tender process. The stored energy will be sold to electricity supply companies (escoms) to support the grid, and there are future plans to sell this energy in the open market as well.

The Future of Solar Energy in Karnataka

As Karnataka continues to expand its solar energy capacity, KREDL’s BESS projects are a crucial part of the state’s renewable energy strategy. With 8,904.14 MW of commissioned solar energy capacity as of August, the state is already a leader in solar power. These BESS projects will further enhance Karnataka’s ability to manage and distribute renewable energy efficiently.

In addition, KREDL is exploring further expansions, including a 250 MW solar plant with a 250 MW/500 MW/h BESS in Ryapte village, Pavagada. While the final decision on this project is pending, it represents the growing momentum behind solar energy storage in the state.
