Refining in Nigeria
Nigeria is one of Africa's largest crude oil producers, yet it has spent decades importing the majority of its refined petroleum products. This paradox is rooted in the chronic underperformance of the country's state-owned refineries and the complex political economy surrounding downstream investment.
Nigeria's Four Refineries
Nigeria built four refineries between 1965 and 1980 with a combined installed capacity of 445,000 barrels per day (bpd).[1] All four are owned by NNPC and have been managed under its refining subsidiary (formerly NNPC Downstream, now NNPC Refining and Petrochemicals).
Port Harcourt Refinery I (Old Port Harcourt)
60,000 bpdCommissioned in 1965 as Nigeria's first refinery, it was originally built by Shell-BP with a capacity of 38,000 bpd and later expanded. Located in Alesa-Eleme, Rivers State, it is the oldest refinery in the country and has undergone several turnaround maintenance cycles with limited success.
Port Harcourt Refinery II (New Port Harcourt)
150,000 bpdCommissioned in 1989, this is the largest of the four NNPC refineries. It was designed to process both light and medium crude oils and includes petrochemical facilities. By the 2010s, its capacity utilisation had dropped to near zero. A major rehabilitation contract was awarded to Maire Tecnimont (Tecnimont SpA) in 2021, with work ongoing to restore the refinery to operational status.
Warri Refinery & Petrochemical Company (WRPC)
125,000 bpdLocated in Ekpan, Delta State, the Warri refinery was commissioned in 1978. It includes a petrochemical plant that produces polypropylene and carbon black. Like the Port Harcourt refineries, it has operated at a fraction of capacity for years, often processing less than 10% of its installed capacity.
Kaduna Refinery & Petrochemical Company (KRPC)
110,000 bpdCommissioned in 1980, the Kaduna refinery is the only inland refinery in Nigeria. It receives crude oil via the Escravos-Kaduna pipeline, which runs over 600 kilometres from the Niger Delta. The pipeline has been frequently vandalised, disrupting crude supply. Kaduna also has a petrochemical component producing linear alkyl benzene (LAB) used in detergent manufacturing.
Between 2019 and 2022, NNPC's annual reports showed that the four refineries collectively operated at capacity utilisation rates ranging from 0% to 5%. During this period, Nigeria spent an estimated USD 7-10 billion annually on petroleum product imports.[3][4]
NNPC Refineries at a Glance
| Refinery | Location | Capacity (bpd) | Year Commissioned | Current Status |
|---|---|---|---|---|
| Port Harcourt I | Alesa-Eleme, Rivers State | 60,000 | 1965 | Under rehabilitation |
| Port Harcourt II | Alesa-Eleme, Rivers State | 150,000 | 1989 | Major rehabilitation (Tecnimont) |
| Warri (WRPC) | Ekpan, Delta State | 125,000 | 1978 | Minimal operation (<10%) |
| Kaduna (KRPC) | Kaduna State | 110,000 | 1980 | Minimal operation |
Why Nigeria Imports Refined Products
The reasons for Nigeria's refining failure are interrelated and structural:
- Deferred maintenance: Turnaround maintenance (TAM) schedules were routinely delayed or underfunded. When TAM contracts were awarded, they were frequently over-budget and under-delivered, with NEITI audit reports documenting cost overruns and procurement irregularities.[5]
- Pipeline vandalism: Crude supply to the refineries - particularly Kaduna - was disrupted by pipeline attacks, reducing feedstock availability even when refining units were operable.
- Political economy of imports: The fuel import and trading sector, which grew significantly under the subsidy regime, created vested interests against domestic refining.[6] As long as subsidised imports were profitable, there was limited incentive to fix the refineries.
- Regulatory uncertainty: The absence of a clear deregulation framework for downstream operations discouraged private investment in refining for decades.
The Dangote Refinery
The Dangote Petroleum Refinery, located in the Lekki Free Trade Zone near Lagos, represents a transformational shift in Nigeria's downstream sector. Built by the Dangote Group at an estimated cost of USD 19 billion, it is the largest single-train refinery in the world.[2]

Key Specifications
| Parameter | Detail |
|---|---|
| Crude Capacity | 650,000 bpd (single-train) |
| Gas Processing | 3 billion scf/day |
| Investment Cost | ~USD 19 billion |
| Location | Lekki Free Trade Zone, Lagos |
| Products | Euro V petrol, diesel, jet fuel, polypropylene |
| Employment | ~30,000 (construction peak), ~5,000 (operations) |
| Crude Grades | Multiple - Bonny Light, Forcados, imported crudes |
The refinery began operations in early 2024, initially processing around 350,000 bpd with plans to ramp up to full capacity. It is designed to produce Euro V-standard petrol and diesel, jet fuel, and polypropylene. At full capacity, the refinery can meet Nigeria's entire domestic fuel demand and export surplus to West African and international markets.
The Dangote Refinery has already disrupted the traditional petroleum import model. It has challenged NNPC's historical monopoly on fuel supply and raised complex questions about pricing, market access, and the future of the fuel subsidy regime.
How Crude Oil Refining Works
Crude oil is heated and fed into an atmospheric distillation column where it separates into different products based on boiling point. Lighter products rise to the top, heavier products settle to the bottom.
Modular Refineries
The Nigerian government has encouraged the development of modular (small-scale) refineries as part of its strategy to boost domestic refining capacity and reduce reliance on imports. Modular refineries typically process between 1,000 and 30,000 bpd.
Several modular refineries have been licensed, including:
- Waltersmith Refinery (Imo State) - 5,000 bpd, operational since 2020 with plans to expand to 50,000 bpd
- AIPCC Energy Edo Refinery (Edo State) - 6,000 bpd condensate refinery
- Duport Midstream (Edo State) - 2,500 bpd modular refinery
While modular refineries will not single-handedly replace imports, they provide localised fuel supply, reduce the environmental damage from artisanal (illegal) refining, and create economic opportunities in host communities.
