Oil and Natural Gas Corporation (ONGC) Green Energy, a subsidiary focused on renewable power, is preparing to launch a tender for a sizable 600 MW solar power project combined with advanced energy storage. The announcement was made by a senior executive, highlighting ONGC’s ongoing commitment to accelerate India’s green energy transition by scaling large-scale solar capacities integrated with battery storage solutions.

Key Highlights:

The upcoming tender will be for a 600 MW solar photovoltaic project integrated with battery energy storage, reflecting the renewable sector’s shift towards dispatchable, stable power supply.

Bidders will be expected to offer turnkey solutions including land acquisition, grid connectivity, engineering, procurement, and construction (EPC), demonstrating an end-to-end project delivery approach.

ONGC will retain responsibility for securing power purchase agreements (PPAs), easing developers’ market risks while enabling competitive project execution.

The minimum bid size is set at 300 MW, encouraging participation by mid-to-large scale developers with adequate technical expertise and resource capacity.

This tender is the first of two identical rounds planned, collectively aiming at 1.2 GW project capacity within ONGC Green Energy’s growing portfolio.

If successful, ONGC plans to replicate this project model to add another 1,200 MW of renewable capacity, integrating renewables more firmly into its energy mix.

The project marks ONGC’s strategic diversification beyond oil and gas, furthering India’s national goal of achieving 500 GW non-fossil fuel energy capacity by 2030.

The tender implementation timeline is expected within the next few months, positioning project commissioning within 2-3 years.

Context and Market Implications:

This move by ONGC Green Energy underlines the significant transformation driven by India’s public sector undertakings in renewable energy adoption. Increased tenders for solar plus storage projects respond to the critical challenge of renewable intermittency and grid stability, leveraging energy storage as a game-changer.

Through this tender, ONGC is expanding its green energy footprint significantly, building on recent investments including the acquisition of Ayana Renewable Power and partnerships with NTPC Green Energy. Its ambition to reach 10 GW renewables by 2030 reflects its commitment to sustainable, low-carbon growth aligned with India’s energy transition roadmap.

The integration of solar with battery storage facilitates flexible power delivery during peak demand, enhancing renewable energy’s competitiveness against thermal power sources. This also opens new market opportunities for clean energy developers equipped with advanced storage technologies.

In summary, ONGC Green Energy’s upcoming tender for a 600 MW solar plus storage project represents a vital milestone in India’s renewable energy landscape, paving the way for scalable, reliable, and large-scale clean power infrastructure contributing to India’s climate targets and energy security.
