The MoU, signed at India Energy Week 2025, was formalised with TPREL CEO Deepesh Nanda and other dignitaries.

Tata Power Renewable Energy – (TPREL), a subsidiary of the Tata Power Company – has partnered the Oil and Natural Gas Corporation (ONGC) to explore opportunities within the battery energy storage system (BESS) value chain.

The non-binding memorandum of understanding (MoU) aims to enhance India’s energy security through the integration of renewable energy and advanced storage solutions.

Signed at India Energy Week 2025, an event held in New Delhi from 11 February to 4 February 2025, the MoU was formalised in the presence of TPREL CEO and managing director Deepesh Nanda, alongside other dignitaries.

The companies will investigate a variety of applications, including utility-scale energy storage systems, grid stabilisation, renewable energy integration and electric vehicle charging infrastructure.

The tie-up will also focus on industrial and commercial energy storage applications as well as microgrid and back-up power solutions.

Nanda stated: “This partnership with ONGC marks a significant milestone in our journey to drive India’s energy transition. Battery energy storage systems (BESS) will play a crucial role in strengthening grid reliability, enabling greater renewable energy integration and supporting India’s 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.”

The partnership aligns with India’s goal of achieving 500GW of non-fossil fuel-based capacity by 2030.

TPREL has also successfully commissioned a BESS project in Rajnandgaon, Chhattisgarh, combining a 100MW solar photovoltaic plant with a 120-megawatt hours utility-scale BESS.

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 India’s energy transition and long-term energy security.”

In November 2024, Tata Power signed a MoU with Druk Green Power to develop 5GW of clean energy capacity in Bhutan.

The proposed capacity includes 4.5GW of hydropower and 500MW of solar projects, with developments such as the 1.1GW Dorjilung hydroelectric power plant, the 740MW Gongri reservoir, 1.8GW of Jeri pumped storage and the 364MW Chamkharchhu IV.
