Prime Minister Narendra Modi inaugurated the enhanced capacity of Oil India‘s Numaligarh–Siliguri Product Pipeline at a public event in Guwahati on March 13, 2026.
The pipeline, originally designed for 1.72 MMTPA, now supports 5.5 MMTPA to accommodate the Numaligarh Refinery’s expansion from 3.0 MMTPA to 9.0 MMTPA. This upgrade aligns with the Government of India’s Hydrocarbon Vision 2030 for the North-East, achieved through infrastructure enhancements, including converting pigging stations into Intermediate Pumping Stations and upgrading facilities at various terminals.
The project, completed as a brownfield initiative, cost approximately ₹750 crore, saving significantly from the approved ₹860 crore budget. It generated around 4.1 million man-hours of employment over three years in Assam and West Bengal, marking a significant boost to the region’s petroleum product transportation infrastructure.
