State-owned Oil and Natural Gas Corporation (ONGC) has signed a preliminary agreement with Tata Power Renewable Energy Ltd to explore collaborative opportunities in the Battery Energy Storage System (BESS) value chain. Noel Tata is the head of Tata Power Renewable Energy Limited (TPREL) a subsidiary of the Tata Group. This partnership aligns with ONGCs commitment to expand its renewable energy portfolio targeting 10 gigawatts of capacity by 2030 as part of its broader goal to achieve net-zero carbon emissions by 2038. The initiative includes efforts in solar and wind energy projects and focuses on developing round-the-clock renewable power capacity to meet sustainability objectives. The pact aims to explore diverse applications across the BESS value chain including utility-scale energy storage systems grid stabilization and ancillary services renewable energy integration and hybrid solutions energy storage for industrial and commercial applications microgrid and backup power solutions and infrastructure for Electric Vehicle (EV) charging. This collaboration highlights ONGCs increasing focus on clean energy innovation and its pursuit of sustainable energy solutions to support Indias transition to a greener future. ONGC On Partnership With TPREL ONGC has signed a non-binding Memorandum of Understanding (MoU) with Tata Power Renewable Energy Ltd (TPREL) a subsidiary of The Tata Power Company Ltd to explore collaborative opportunities in the BESS value chain at India Energy Week 2025 the firm said in a statement. This strategic partnership underscores ONGCs commitment to enhancing Indias energy security through the integration of renewable energy and advanced storage solutions it said. ONGC chairman and CEO Arun Kumar Singh said 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 Indias energy transition and long-term energy security. TPREL On New Collaboration Deepesh Nanda CEO & Managing Director TPREL commented This partnership with ONGC marks a significant milestone in our journey to drive Indias energy transition. Battery Energy Storage Systems will play a crucial role in strengthening grid reliability enabling greater renewable energy integration and supporting Indias ambitious clean energy goals. Together with ONGC we aim to develop innovative storage solutions that will pave the way for a sustainable and resilient energy future. This collaboration aligns with Indias goal of achieving 500 GW of non-fossil fuel-based capacity by 2030 reinforcing both companies commitment to sustainability. TPRELs successful commissioning of Indias largest Solar and Battery Energy Storage System (BESS) project - a 100 MW Solar PV plant with 120 MWh Utility-Scale BESS at Rajnandgaon Chhattisgarh demonstrates its leadership in deploying advanced energy storage technologies. The partnership between ONGC and TPREL is a significant milestone in fostering technological innovation energy efficiency and sustainability contributing to the development of a robust and resilient energy infrastructure for the nation. ONGC is Indias largest producer of crude oil and natural gas accounting for approximately 71 per cent of the countrys domestic production. TPREL has a diversified portfolio encompassing solar wind and hybrid energy projects.  (With inputs from PTI)
