Tata Power Renewable Energy and ONGC Collaborate on Battery Energy Storage Solutions

Tata Power Renewable Energy Limited (TPREL), a subsidiary of Tata Power, has entered into a strategic collaboration with Oil and Natural Gas Corporation Limited (ONGC) to explore opportunities in the Battery Energy Storage System (BESS) sector. The non-binding Memorandum of Understanding (MoU) was signed at India Energy Week 2025, signifying a major step towards integrating advanced energy storage solutions into India’s renewable energy landscape.

Exploring Multiple Avenues in Energy Storage 

The partnership between TPREL and ONGC aims to identify and develop commercial opportunities across various segments of the BESS value chain. These include utility-scale storage solutions, grid stabilisation services, microgrid development, hybrid energy solutions, industrial and commercial storage applications, backup power, electric vehicle (EV) charging infrastructure, and energy trading through ancillary services. This collaboration underscores the growing importance of energy storage in ensuring grid reliability and renewable energy integration.

Industry Leaders’ Perspective 

Commenting on the collaboration, Deepesh Nanda, CEO & Managing Director of TPREL, highlighted the significance of battery energy storage in accelerating India’s clean energy transition. “Battery Energy Storage Systems will play a crucial role in strengthening grid reliability, enabling greater renewable energy integration, and supporting India’s ambitious clean energy goals. Together, we aim to develop innovative storage solutions that will pave the way for a sustainable and resilient energy future.”

Echoing similar sentiments, Arun Kumar Singh, Chairman and CEO of ONGC, emphasised the company’s commitment to advancing clean energy initiatives. “As India transitions towards a sustainable energy future, ONGC remains steadfast in its commitment to advancing clean energy initiatives. This collaboration with Tata Power Renewable Energy Limited represents a strategic step towards strengthening energy storage capabilities, which are vital for grid stability and renewable energy adoption. By leveraging our collective expertise, we aim to contribute meaningfully to India’s energy transition and long-term energy security.”

Driving Innovation in Renewable Energy 

This partnership builds on TPREL’s expertise in large-scale battery energy storage projects. Notably, the company successfully commissioned India’s largest Solar and Battery Energy Storage System (BESS) project—a 100 MW Solar PV plant with a 120 MWh utility-scale BESS in Rajnandgaon, Chhattisgarh. Such projects set a benchmark for future BESS initiatives and contribute to strengthening India’s green energy infrastructure.
