20% of the power demand for India’s largest onshore oil production field in Barmer, Rajasthan, to be met through renewable energy

Agreement to source 25 MW Renewable hybrid energy will help reduce 115 kilotonnes of CO₂e emissions annually; equivalent to planting 5.75 million trees per year

New Delhi, 2^nd April 2026: Cairn Oil & Gas, part of Vedanta Group and India’s leading private oil and gas exploration and production company, in partnership with Serentica Renewables India Pvt. Ltd, a leading renewable energy provider, has commenced sourcing 25 megawatts (MW) of captive renewable hybrid power. The companies have signed a Power Delivery Agreement to support Cairn’s operations in Barmer, Rajasthan.

Under this agreement, 20% of the power demand for India’s largest onshore oil producing asset will be met through renewable hybrid energy.

The agreement represents a key milestone for India’s energy journey, combining Cairn’s operational leadership in India’s energy sector with Serentica Renewables’ expertise in delivering reliable, round-the-clock renewable power. It reflects a shared commitment to accelerating India’s energy transition while maintaining energy security.

As per the agreement, Cairn has begun sourcing renewable hybrid power generated through solar and wind energy from Serentica Renewables’ Gadag facility in Karnataka. The transition is expected to reduce operational carbon emissions by approximately 115 kilotonnes of CO₂e annually — equivalent to planting 5.75 million trees each year — while also strengthening compliance with statutory Renewable Purchase Obligation (RPO) mandates.

Structured at a 70% Capacity Utilisation Factor (CUF), the 25 MW agreement will deliver approximately 153 million units of renewable energy annually to the Mangala facility, operated by Cairn in Barmer. Advancing emission reduction represents a strategic shift towards low-carbon energy consumption and enhanced operational efficiency, while driving Cairn’s broader vision of contributing 50% of India’s domestic oil and gas production.

This strategic partnership marks a significant milestone in integrating clean energy into Cairn’s core operations and reinforces its commitment to embedding sustainability at the heart of its business model. The agreement forms part of Cairn’s broader roadmap to expand renewable energy use by the end of the decade, accelerating its journey towards achieving Net Zero Carbon.

Over the past three decades, Cairn has remained at the forefront of sustainability-led transformation in the oil and gas sector, aligned with India’s socio-economic and environmental priorities. Together with Serentica Renewables, this collaboration sets a new benchmark for integrating clean energy into conventional energy operations, reinforcing the role of partnerships in accelerating India’s low-carbon transition.
