Oil India Limited has mechanically completed the upgradation of its Numaligarh-Siliguri Product Pipeline, increasing capacity from 1.77 MMTPA to 5.50 MMTPA. This upgrade supports the Numaligarh Refinery expansion and enhances energy security in Northeast India, boosting fuel supply reliability and regional economic growth.

Oil India Limited (OIL) has announced the mechanical completion of its flagship infrastructure project—the upgradation of the Numaligarh-Siliguri Product Pipeline (NSPL)—on October 12, 2025. This critical development aligns with India’s energy security goals and represents a significant enhancement of the company’s midstream infrastructure to serve the growing energy demands of Northeast India.

The NSPL upgradation project has increased the transportation capacity of the existing pipeline from 1.77 million metric tonnes per annum (MMTPA) to 5.50 MMTPA. This substantial capacity enhancement is directly linked to the ongoing Numaligarh Refinery Expansion Project by Numaligarh Refinery Ltd., which is ramping up refinery output from 3.00 MMTPA to 9.00 MMTPA. Together, these projects form a comprehensive strategy to strengthen petroleum product supply and infrastructure in the Northeast region.

Key highlights of the project include:

Mechanical completion date: October 12, 2025
Capacity increase from 1.77 MMTPA to 5.50 MMTPA
Supports and complements the refinery capacity expansion at Numaligarh Refinery
Enhances energy security and product availability for Northeast India
Expected to drive economic growth by improving fuel supply reliability and enabling industrial development
Demonstrates Oil India’s commitment to strengthening India’s energy infrastructure and self-reliance objectives

The completion of this upgrade positions Oil India as a pivotal player in expanding and modernizing energy infrastructure. It facilitates seamless handling of increased petroleum product flows, critically supporting the economic and energy needs of the Northeast, a region of strategic importance for India.

This milestone also underscores Oil India’s operational efficiency and expertise in executing large-scale infrastructure projects, reinforcing its status as a Maharatna Central Public Sector Enterprise.

Looking ahead, this boosted capacity pipeline will strengthen the supply chain, reduce logistics bottlenecks, and contribute to stable fuel supply for both domestic consumption and commercial enterprises in the area.
