Numaligarh Refinery Limited (NRL), India’s newest Maharatna, aims to commission a 9 MMTPA capacity expansion by March 2027. The project will position the refinery as a dominant fuel supplier in Eastern and Northeastern India and beyond.

  • Capacity increase from 3 MMTPA to 9 MMTPA.
  • Project 87.1% complete; commissioning targeted for March 2027.
  • Strategic supply push into Eastern, Northeastern states and neighboring countries.

Numaligarh Refinery Limited (NRL), the latest Maharatna in India, announced that its 9 MMTPA expansion will be commissioned by March 2027, tripling its current refining capacity. This scale‑up is set to make NRL the leading fuel supplier in the East and the North‑East.

NRL is a subsidiary of Oil India Limited (OIL) and is also known as the “Assam Accord Refinery,” a promise embedded in the 1985 Assam Accord that ended a six‑year violent agitation aimed at expelling undocumented foreigners from the state.

Chairman‑MD Ranjit Rath disclosed that physical progress on the expansion stands at 87.1% and the plant is expected to be operational by March 2027. He emphasized that the added capacity will serve West Bengal, the eight North‑Eastern states, and even supply diesel to Bangladesh via Siliguri.

Historical Background

The Assam Accord of 1985 was a watershed political settlement that concluded a prolonged insurgency. One of its key commitments was the establishment of a large‑scale refinery in Assam, which materialised as the Numaligarh Refinery. Located in Golaghat district, it remains the sole Indian facility delivering high‑altitude diesel to Bhutan.

Elevated from Miniratna‑Category‑1 to Navaratna status in December 2025, NRL reported a 17.69% rise in net worth for FY 2025‑26 and a profit after tax surge of over 90% to ₹3,057 crore, underscoring its robust financial health.

Why This Matters

BozokMedia analysis shows that the tripling of NRL’s refining capacity will not only reshape India’s domestic fuel logistics but also create a strategic export hub for neighboring countries such as Bangladesh, Bhutan, and potentially Myanmar once stability returns. This aligns with India’s broader energy security agenda and regional influence objectives.

"NRL’s expansion is a game‑changer for the North‑East, turning a historically underserved region into a fuel‑rich corridor," says Dr. Asha Singh, Energy Policy Analyst.
