Oil India upgrades pipeline, secures gas supply for energy security

Oil India Limited (OIL) announced the mechanical completion of its Numaligarh-Siliguri Product Pipeline (NSPL) on October 12, 2025. This flagship infrastructure project increases the pipeline's transportation capacity from 1.77 mmtpa to 5.5 mmtpa, strengthening OIL's ability to handle increased product flows from the Numaligarh Refinery, which is expanding from 3.0 mmtpa to 9.0 mmtpa. The NSPL upgradation project, covering Assam and West Bengal, includes five pump stations and one receipt terminal, affirming OIL's commitment to energy infrastructure in the Northeastern region.

Concurrently, OIL signed a new 15-year Gas Sale and Purchase Agreement (GSPA) with North Eastern Electric Power Corporation Limited (NEEPCO) for continued supply of 1.4 mmscmd of natural gas to NEEPCO's Assam Gas Based Power Station (AGBPS) at Bokuloni, Dibrugarh. This agreement, succeeding an earlier 10-year arrangement, ensures sustained gas supply and supports regional energy security.

These milestones underscore OIL's strategic focus on expanding its upstream portfolio and contributing to India's transition towards a gas-based economy, securing power needs for Assam and the Northeast with affordable, clean energy.
