Cost of Numaligarh Refinery expansion set to swell to Rs 34,000 crore as revamp nears finish

The capacity expansion of Numaligarh Refinery is likely to see its project cost rise by nearly Rs 5,900 crore to about Rs 34,000 crore, with a revised proposal now under government review. The brownfield project to triple refining capacity to 9 MMTPA is already 85% complete and targets commissioning by December 2026. Funded via a 70:30 debt-equity mix led by SBI, the upgrade will sharply boost fuel output and is part of a broader roadmap that also includes petrochemical expansion and a green hydrogen facility.
