Numaligarh Refinery Expansion Cost to Rise to Rs 340 Billion

26 Feb 2026 CW Team

Officials indicated that the revision follows a detailed reassessment of project inputs, though formal explanations from the company have been limited. The update is likely to account for higher material and equipment prices, extended procurement timelines and prevailing market conditions without attributing the increase to any single factor. Analysts will watch the process for indications of cost control measures and any revisions to project scope that may accompany the new estimate.

The request for government nod places emphasis on securing approvals that affect funding, clearances and possible fiscal support mechanisms. Stakeholders, including lenders, suppliers and state authorities, will need to appraise the revised economics before committing further resources. Local communities and contractors may be affected by changes to construction schedules and employment forecasts as the project moves into its next phase. Financiers are likely to re-evaluate exposure to the Rs 340 bn proposal.

The approval process is expected to involve scrutiny of revised financial projections, environmental clearances and contractual frameworks, and authorities will evaluate the proposal against policy priorities. Any decision will influence the refinery sector's investment climate and could set a precedent for transparency in reporting cost escalations. The company has indicated it will engage with regulators and partners to address queries arising from the estimate revision promptly for scrutiny.

The company has filed formal proposals with the relevant authorities to obtain the requisite nod for the revised budget. The adjustment reflects a substantial escalation from earlier estimates and positions the project as one of the larger recent refinery expansions under consideration in the country.
