List of Oil Refinery Companies and Plants in India

Projects India currently tracks 116 upcoming petroleum refinery and refinery-linked projects across the country, spanning new grassroots plants, capacity expansions and petrochemical complexes. The promoters behind them range from central public sector undertakings such as Indian Oil Corporation Limited and Bharat Petroleum Corporation Limited to private developers such as Nayara Energy and Reliance Industries. Combined recorded project cost across this Petroleum Products [Refinery] pipeline stands at about Rs 12.57 lakh crore.

List of Refinery Companies in India: Most Active Promoters

The table below draws on our database as of October 2026 and lists every promoter for whom we track at least one petroleum refinery project, along with the total number of projects and their combined recorded cost. As the chart below shows, a handful of organisations account for the bulk of activity.

Indian Oil Corporation Limited leads by project count with 29 entries in our records, reflecting its multi-refinery footprint across locations including Panipat and Mundra. BPCL has the highest combined recorded cost at about Rs 2.52 lakh crore, driven largely by two large greenfield refinery proposals in Andhra Pradesh added to our database within the last 90 days. Nayara Energy appears once in the promoter list but with a single project valued at about Rs 1.30 lakh crore, making it one of the largest individual entries by cost. For those preparing vendor or EPC outreach lists, these thirteen organisations represent the primary decision-making entities in India's upcoming refinery pipeline.

Largest Individual Refinery Projects Currently in Our Database

The fifteen largest projects by recorded cost, drawn from our projects intelligence database, are listed below. Two of these — both BPCL greenfield refineries in Nellore, Andhra Pradesh — were added to our records within the last 90 days, signalling fresh movement in that corridor.

Of the fifteen projects above, only the HPCL Rajasthan Refinery project at Barmer has reached the Construction Started stage, making it the most immediately relevant for EPC subcontractors and equipment suppliers looking for near-term purchase orders. The remaining large projects are spread between Planning and Under Approvals, meaning procurement cycles are typically still some months away. Suppliers and consultants who establish relationships now position themselves ahead of formal tendering. See our companion piece on refinery EPC contractors and construction companies in India for the contracting ecosystem around these projects.

Where Refinery Demand Is Concentrated: States and Project Stages

As the chart below shows, Gujarat and Andhra Pradesh lead in project count, each with significant investment across both existing refinery hubs and proposed new locations.

Our records show the following state-wise distribution of petroleum refinery projects:

• Gujarat (16 projects): Established processing hubs at Vadinar and Kachchh, with the Nayara Energy expansion and the IOCL Mundra petrochemical project among the headline entries.
• Maharashtra (15 projects): Dominated by the Ratnagiri refinery proposals, alongside other petroleum processing investments along the coast.
• Andhra Pradesh (15 projects): A fast-growing corridor, with BPCL's two Nellore greenfield proposals, the Kakinada SEZ entry by Haldia Petrochemicals, the Kakinada Refinery and Petrochemicals project and HPCL's Visakhapatnam project all visible in our database.
• Assam (12 projects): Reflects the historic refinery concentration in the northeast, anchored by Numaligarh Refinery Limited which accounts for 7 tracked projects in this scope.
• Tamil Nadu (10 projects): CPCL drives most activity, with both a Nagapattinam expansion and a Cauvery Basin project recorded.
• West Bengal and Uttar Pradesh (7 each), Odisha (6), Bihar and Haryana (5 each): Smaller but consistent pipelines, often linked to product pipeline terminals, storage and smaller processing units.

As the chart below shows, the stage distribution across all petroleum refinery projects in our database — including completed and cancelled entries — places the largest share Under Approvals, followed by Construction Started and Planning.

With 54 projects Under Approvals and 21 in Planning, the pipeline of work entering active procurement over the coming period is substantial. The 33 projects at Construction Started stage represent immediate on-site demand for civil works, equipment supply and specialist services. Of the 116 upcoming (non-completed, non-cancelled) projects, 30 carry verified status in our records, providing a higher-confidence subset for sales teams that need to prioritise outreach.

How to Approach These Companies

The stage a project occupies signals which team within the promoting organisation is likely to be receptive and what kind of conversation makes sense.

Planning and Under Approvals: At these early stages the project team is typically focused on techno-economic feasibility, environmental clearances and technology selection. Suppliers of licensed process technology, project management consultants, environmental consultants and basic engineering firms are the most relevant parties. Procurement of major equipment has generally not begun, but vendor pre-qualification processes sometimes start here, particularly for long-lead items such as reactors, columns and fired heaters. Introducing your company and capabilities to the project development or corporate strategy team at the promoting organisation is the appropriate step.

Approvals Received: Two projects in our database carry this status. This is the stage at which detailed engineering contracts are often awarded and EPC tender preparation begins. Equipment suppliers should ensure they are on any vendor-approved lists before formal enquiries go out.

Construction Started: With 33 projects at this stage, on-site procurement of civil materials, structural steel, piping, instrumentation and contractor labour is typically active. Project managers, construction managers and site procurement officers become the key contacts. Subcontractor packages for specialist work — insulation, fireproofing, electrical installations — are often floated at this stage.

Because the majority of promoters in this space are central or state public sector entities, commercial engagement generally follows published tender processes. Monitoring live government tenders in the petroleum sector is essential for capturing packages as they are floated. Private promoters such as Nayara Energy and Reliance Industries tend to follow their own vendor management and nomination procedures.

What This Means for Suppliers and Contractors

The scale of the refinery project pipeline — Rs 12.57 lakh crore in recorded cost across 116 upcoming projects — creates sustained demand across a wide range of product and service categories. The key implications for B2B teams are as follows.

• EPC and LSTK contractors should focus attention on the projects at Barmer (Construction Started), which represent near-term package awards, while building relationships with BPCL, IOCL and CPCL project teams ahead of Approvals and Planning-stage projects moving forward.
• Equipment suppliers — particularly those supplying heat exchangers, pressure vessels, rotating machinery, fired equipment and instrumentation — should note that the Andhra Pradesh corridor has added two major BPCL greenfield entries in the last 90 days alone, signalling accelerating project development activity in that state.
• Civil and structural contractors will find the highest near-term opportunity in the 33 Construction Started projects. Gujarat, Andhra Pradesh and Assam are the primary geographies.
• Consultants and technology licensors should engage promoters at the Planning and Under Approvals stages. The 54 projects Under Approvals represent the largest single cohort and include some of the highest-value entries in the database.
• Logistics and materials suppliers should note that project sites in Ratnagiri (Maharashtra) and Barmer (Rajasthan) present supply-chain complexity given their locations, creating opportunity for specialist logistics providers.

For teams building a structured outreach programme, the Projects India intelligence database allows filtering by promoter, state, stage and project type to generate targeted prospect lists. A free sample project report is available for teams evaluating the platform before committing to a subscription. Those focused on the broader energy and industrial construction market may also find value in our coverage of upcoming oil and gas projects in India and new fertilizer plant projects, which share many of the same promoters and EPC contractors.
