Numaligarh Refinery Limited has revised the cost estimate for its expansion project to Rs 340 billion (bn) and has sought government approval for the higher budget. The company indicated that the revised figure supersedes earlier estimates and will alter the capital requirements for the scheme. The expansion is intended to increase processing capacity and modernise facilities, subject to regulatory clearance. Officials said the request was submitted to federal authorities for consideration and clearance. The revision reflects an upward adjustment driven by increased capital outlay, higher commodity prices and changes in project scope, according to the firm. The company noted that detailed engineering and procurement assessments had identified areas where expenditure had risen beyond initial projections. Supply chain disruptions, foreign exchange movements and labour cost inflation were cited as contributing factors. Management has initiated a review of project schedules to accommodate the updated financial plan. Financing for the enlarged budget is expected to combine internal accruals, debt and potential partner contributions, with the final structure contingent on approvals. The refinery will engage lenders and stakeholders to align funding arrangements with revised timelines and cash flow projections. Discussions are likely to address tenure, pricing and security for any borrowing. Regulatory clearances and statutory permits are likely to be sought or updated as part of the approval process. The expansion has implications for refining capacity and regional fuel supply and could affect downstream industries and employment, contingent on timely execution. Local suppliers and contractors are likely to be engaged during the construction and commissioning phases, supporting jobs and procurement demands. The project could support skill development and ancillary services in the host region, depending on contractor selection. The company will await government decision before finalising procurement and contracting schedules.
