Cairn Oil & Gas, part of the Vedanta Group and one of India’s leading private oil and gas exploration and production companies, has begun sourcing 25 megawatts (MW) of captive renewable hybrid power through a partnership with Serentica Renewables India Pvt. Ltd.. The two companies have signed a Power Delivery Agreement to supply clean energy to Cairn’s operations in Barmer, marking a significant step toward integrating renewable power into one of the country’s most important hydrocarbon assets.
Under the arrangement, 20 percent of the power requirements of India’s largest onshore oil-producing facility will be met through a blend of solar and wind energy. The agreement underscores a strategic shift in India’s energy landscape, combining Cairn’s long-standing role in domestic oil production with Serentica Renewables’ capability to deliver dependable, round-the-clock renewable power. It also reflects a shared intention to advance the country’s energy transition while ensuring stability and security of supply.
Cairn has already begun receiving hybrid renewable energy generated at Serentica’s facility in Karnataka, supporting a substantial reduction in emissions from its upstream operations. The initiative is expected to cut approximately 115 kilotonnes of CO₂e per year—an impact comparable to planting about 5.75 million trees annually—while strengthening compliance with statutory Renewable Purchase Obligation (RPO) requirements.
The 25 MW agreement is designed at a 70 percent Capacity Utilisation Factor, enabling the delivery of roughly 153 million units of renewable power annually to Cairn’s Mangala facility in Barmer. This shift toward low-carbon energy is aligned with Cairn’s broader ambition to supply half of India’s domestic oil and gas production while maintaining operational efficiency and reducing its environmental footprint.
The partnership represents an important step in embedding sustainability into Cairn’s core business operations. It forms part of the company’s long-term roadmap to expand its renewable energy usage by the end of the decade, further accelerating its progress toward achieving Net Zero Carbon. Cairn, which has been active for more than three decades, continues to position itself at the forefront of environmentally responsible growth in India’s oil and gas sector, supporting national goals across both economic development and climate priorities.
In collaboration with Serentica Renewables, this initiative establishes a new benchmark for integrating clean power into conventional energy operations. It also reinforces the growing role of strategic partnerships in advancing India’s low-carbon transition, demonstrating how traditional and renewable energy players can work together to accelerate the shift toward a more sustainable energy future.
