Refinery EPC Contractors and Construction Companies in India

Projects India currently tracks 115 upcoming petroleum refinery projects across the country, with a combined recorded cost of approximately Rs 11.54 lakh crore. The promoters behind this pipeline are dominated by central public sector undertakings — Indian Oil Corporation Limited, Bharat Petroleum Corporation Limited and Hindustan Petroleum Corporation Limited — alongside state-level entities and a small number of private players. EPC contractors, construction firms, and equipment suppliers looking for refinery work will find the active buyers listed below.

Most Active Promoters Commissioning Refinery Projects

The table below draws from our database as of September 2026 and covers all petroleum refinery projects Projects India records nationally, including those under approvals, in planning and under construction. These are the organisations awarding EPC, civil, mechanical and equipment contracts.

As the chart below shows, Indian Oil Corporation Limited leads by project count, with 29 projects in our records — a significant share of the national pipeline for any contractor building a target account list.

For contractors compiling a Panipat refinery contractors list, Indian Oil Corporation Limited is the promoter to track: our database records a petroleum products project at Panipat, Haryana valued at Rs 25,600 crore, currently in planning. For those seeking a Pachpadra refinery contractors list, HPCL Rajasthan Refinery Limited is the relevant buyer, with a project at Pachpadra, Barmer, Rajasthan worth Rs 43,129 crore that has already entered construction. Numaligarh Refinery Limited is the promoter for projects in Assam, which is relevant background for any firm researching the Barauni refinery contractors list or adjacent Bihar-Assam corridor activity.

Largest Individual Refinery Projects in the Pipeline

The fifteen projects below represent the highest-value opportunities in our petroleum refinery database as of September 2026. Stage indicates where each project currently sits in its lifecycle — relevant for timing outreach and bid preparation.

The BPCL project at SPSR Nellore — recorded at Rs 1,03,408 crore — was added to our database within the last 90 days, making it among the most recently tracked large-scale refinery opportunities available to contractors and suppliers monitoring the pipeline.

Where Refinery Demand Is Concentrated — States and Project Stages

Gujarat and Andhra Pradesh lead the state-wise count of petroleum refinery projects in our database, followed closely by Maharashtra and Assam. The full distribution of upcoming projects by state is shown in the chart below.

Gujarat accounts for 16 projects, Andhra Pradesh 14, Maharashtra 15, and Assam 12 — together representing a significant share of the national refinery construction pipeline. Tamil Nadu, West Bengal, Uttar Pradesh, Odisha, Bihar and Haryana each contribute between 5 and 10 projects, signalling that refinery activity is distributed across both established refining corridors and newer locations.

On stage, the distribution across all projects in this scope — including completed and cancelled — shows that the majority are either Under Approvals (53 projects) or have Construction Started (33 projects), with a further 21 in Planning. As the chart below illustrates, this means contractors need to monitor both the approvals pipeline and active construction simultaneously.

Of the 115 upcoming projects Projects India tracks in this scope, 29 are marked verified — meaning our research team has confirmed key project details. Only 1 project was added to our database in the 90 days before September 2026, and 1 in the 90 days before that, reflecting the long gestation cycles typical of refinery-scale investments rather than a slowdown in overall activity.

How to Approach These Companies as a Refinery Contractor or Supplier

Timing an approach to a refinery promoter correctly is as important as qualifying the opportunity itself. The stage of a project determines who in the organisation is making procurement decisions and what they are ready to discuss.

• Planning and Under Approvals: At this stage, the promoter's project development and business development teams are active. EPC firms, licensor-technology partners and specialist consultants can begin relationship-building and pre-qualification conversations. Procurement has not formally opened, but vendor registrations and expression of interest processes sometimes begin here for long-lead items such as reactors, heat exchangers and rotating equipment.
• Approvals Received: This is the window immediately before tendering. Front-end engineering design (FEED) contractors, PMC firms and specialist sub-contractors should be positioned before the formal tender notice appears. For large public sector promoters such as Indian Oil Corporation Limited or Bharat Petroleum Corporation Limited, this stage often precedes a published tender by months.
• Construction Started: Active procurement of civil, structural, piping, electrical and instrumentation packages is underway. The Pachpadra refinery (HPCL Rajasthan Refinery Limited, Rs 43,129 crore) and the Delayed Coker Unit at Kochi (BPCL, Rs 20,000 crore) are both at this stage, meaning packages are being awarded now or in the near term. Suppliers of bulk materials — pipe, valves, structural steel, cables — should treat Construction Started projects as immediate targets.
• Nearly Completion: Opportunities here are limited to O&M contracts, commissioning support, spares supply and snag-list remediation work.

For public sector promoters, formal procurement almost always flows through published tenders. Monitoring live government tenders alongside the project pipeline gives contractors the earliest sight of bid notices before they appear on individual PSU portals.

For private promoters — Nayara Energy, Ratnagiri Refinery and Petrochemicals Limited, Haldia Petrochemicals — procurement processes can be less standardised. Early engagement at the project development stage, before a formal EPC tender is floated, is generally more effective than waiting for a published notice.

Within a project team, procurement authority typically sits with the Project Director or Head of Projects, while technical specifications are controlled by process and engineering leads. For large packages, the Chief Financial Officer and board-level committees are involved in final approvals. Vendor registration, however, is usually managed by the Materials or Contracts department and is worth completing well before a specific tender is announced.

What This Means for Refinery EPC Contractors and Suppliers

The refinery project pipeline tracked in our database — spanning Rs 11.54 lakh crore across 115 upcoming projects — represents an extended period of procurement activity for the sector. Several practical implications follow for contractors and B2B suppliers.

Scale of opportunity by promoter: Indian Oil Corporation Limited alone accounts for 29 projects worth approximately Rs 1.81 lakh crore. A contractor or equipment supplier with IOCL on their client list has access to the single largest block of refinery work in our database. BPCL and HPCL together add a further 21 projects worth over Rs 2.11 lakh crore combined.

Geographic concentration matters for mobilisation: Gujarat, Andhra Pradesh, Maharashtra and Assam together account for 57 of the state-tagged projects in our records. Contractors without established site presence or regional sub-contractor networks in these states face a structural disadvantage when bidding for packages that require rapid mobilisation.

Pipeline depth versus near-term revenue: The majority of projects by count are Under Approvals or in Planning — meaning revenue for most contractors lies ahead by months or longer, not immediately. The two projects already at Construction Started (Pachpadra and Kochi) are where near-term contract awards are most likely. Contractors should calibrate their pipeline reporting accordingly rather than treating all 115 projects as equally imminent.

Verified project intelligence reduces wasted pursuit costs: Of the 115 upcoming projects in our scope, 29 are marked verified in our database. Pursuing unverified or stale project leads consumes bid preparation resources without result. Accessing verified, stage-tagged project data — with promoter, location, cost and stage confirmed — materially improves bid conversion rates for sales and business development teams.

Contractors and suppliers who want to build a live target account list from this pipeline can explore petroleum refinery projects tracked by Projects India, review the broader mining and energy sector overview, or request a free sample project report to assess data depth before subscribing. Teams managing large tender volumes may also find value in AI tender intelligence to prioritise notices that match their capability profile. For firms building supplier or sub-contractor relationships, the VendorConnect contractor and supplier directory provides a starting point for identifying registered companies active in the refinery sector.
