Cairn Oil Locks 25-MW Green Power PPA in India

India’s Cairn Oil has signed a 25-MW renewable power purchase agreement with Serentica, securing contracted green electricity to support its operations and lower Scope 2 emissions. The deal follows a broader push by industrial and energy firms to lock in long-term clean power supplies for cost and emissions management.

For Cairn, the PPA is expected to provide greater price and supply predictability versus relying on variable grid tariffs, improving sustainability reporting. For Serentica, the contracted offtake reduces revenue risk and can help underpin project financing and build decisions, particularly when paired with strong performance and telemetry arrangements.

How will Cairn’s 25MW PPA with Serentica cut Scope 2 emissions?

  • Scope 2 emissions come from the electricity Cairn purchases to run offices, processing/production facilities, and other on-site loads. A 25MW PPA switches that purchased power from the grid mix toward contracted renewable generation.
  • By taking renewable electricity volumes under the PPA, Cairn can reduce the carbon intensity of the electricity it uses—effectively displacing higher-emission generation that would otherwise be supplied through the general grid.
  • If the PPA includes renewable energy attributes (e.g., certificates/RECs/green power claims), those attributes can be used for emissions accounting so Cairn’s reported electricity-related emissions reflect the lower-carbon power sourced through the contract rather than the average grid factor.
  • Contracted, contracted-at-scale renewables can improve “market-based” emissions figures by enabling Cairn to report electricity using contract-specific emissions factors instead of the general location-based grid average (where accounting rules allow).
  • Matching contracted renewable output to Cairn’s consumption over the contract term helps ensure that a greater share of Cairn’s annual electricity use is covered by low-emission power, lowering total Scope 2 emissions each reporting period.
  • A long-term supply agreement reduces the likelihood that Cairn must rely on more carbon-intensive residual grid supply during peak demand windows, which can otherwise raise average emissions intensity.
  • Cleaner electricity procurement can also support broader operational efficiency initiatives (e.g., better planning for power demand, load management, and electrification measures) that indirectly reduce total electricity use and therefore Scope 2 emissions.
  • Improved performance and telemetry tied to the PPA enables Cairn to quantify how much renewable power was delivered and matched, strengthening the data quality behind Scope 2 calculations and sustainability disclosures.
