Cairn Oil & Gas, a unit of Vedanta Limited, has integrated 25 MW of round-the-clock (RTC) renewable power into its Barmer basin operations in Rajasthan. This commencement serves as the initial phase of a strategic mandate to source 70 MW of renewable energy by 2030. The power delivery agreement (PDA) is designed to provide stable, carbon-free energy to the company’s Rajasthan assets, facilitating a transition toward a Net Zero operational structure.
Project Logistics and Technical Specifications
The integration of renewable energy into the Rajasthan operational footprint is defined by the following technical parameters and capacity targets:
- Current Capacity: 25 MW
- Future Expansion: Target of 70 MW by 2030
- Primary Facility: Mangala Processing Terminal (MPT)
- Geographic Location: Barmer, Rajasthan
- Operational Type: Round-The-Clock (RTC) renewable energy sourcing
- Secondary Agreement: A second PDA for an additional 47 MW is scheduled for finalization in FY 2025
Environmental Impact and Decarbonization Metrics
The shift to renewable power and the implementation of technical efficiency measures are projected to reduce the company’s carbon intensity. Current performance and long-term targets are summarized in the table below:
| Metric | Value/Goal |
| Annual GHG reduction potential from initial MPT pump conversion | 86,000 tCO2e |
| Total trees to be planted by 2030 | 2 million |
| Reduction in flare gas volume from 2021 baseline | 60% |
| Net Zero Carbon target year | 2030 |
Beyond operational efficiency, Cairn is utilizing “Nature-Based Solutions” to sequester carbon and restore local ecosystems. These efforts are formalized through Memorandums of Understanding (MoUs) with state departments, including the afforestation of 700 hectares in Barmer, Rajasthan (comprising 0.35 million plantations), and the development of 190 hectares of mangroves in Gujarat.
Operational Integration and Corporate Context
The sourcing of renewable energy is synchronized with the electrification of field equipment to maximize decarbonization. Cairn recently invested INR 0.492 billion to replace a steam-driven power fluid pump at MPT with a 5 MW electric motor-driven unit. This conversion creates the specific power demand that the new 25 MW renewable sourcing fulfills.
Key operational metrics regarding this transition include:
- Renewable Energy Contribution: 16% of the field’s total power requirement.
- Future Electrification: The conversion of two additional steam-driven pumps is planned for FY 2024-25, which is projected to reduce emissions by a further 130,000 to 136,000 tCO2e/annum.
Strategic Alignment with National Goals
Cairn’s renewable energy roadmap aligns with the Government of India’s “Panchamrit” plan, which targets a reduction in carbon emissions by 1 billion metric tonnes by 2030, and the “Energy Aatmanirbharta” vision for national self-reliance.
The company currently accounts for 25% of India’s domestic crude oil production and has established a goal to increase this contribution to 50%. This production growth is being pursued in tandem with the 2030 Net Zero Carbon commitment, supported by the ongoing finalization of a second 47 MW Power Delivery Agreement.
