Edo Refinery recorded the highest capacity utilisation among Nigeria’s operating modular refineries in August 2026, reaching 90.43 percent, according to the latest data from the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA).
The refinery was one of four modular facilities recorded as operational during the month, alongside WalterSmith Refinery, Aradel Refinery and OPAC Refinery. Duport Refinery was listed as shut down in the regulator’s August 2026 State of the Midstream and Downstream Sector factsheet.
WalterSmith recorded the second-highest utilisation at 64.77 percent, followed by Aradel Refinery at 58.77 percent. OPAC Refinery recorded the lowest utilisation among the operating facilities at 16.97 percent.
Despite recording the highest utilisation rate, Edo Refinery did not have the highest reported Automotive Gas Oil (AGO) output during the month.
Aradel Refinery recorded the largest AGO production at 0.31 million litres per day (ML/D), followed by WalterSmith at 0.28 ML/D, OPAC at 0.11 ML/D and Edo at 0.08 ML/D.
Aradel also recorded the highest reported domestic AGO receipts at 0.33 ML/D. WalterSmith recorded 0.29 ML/D, while OPAC and Edo recorded 0.09 ML/D and 0.08 ML/D respectively.
Combined AGO production from the four operating modular refineries stood at 0.78 ML/D in August, while reported domestic AGO receipts averaged 0.79 ML/D.
The NMDPRA figures show significant differences in operating levels across the modular-refinery segment. Edo operated at more than 90 percent of its reported capacity, while WalterSmith and Aradel operated at above 50 percent. OPAC, however, operated at less than one-fifth of capacity.
The figures also show that capacity utilisation and absolute production volume did not move in the same order. Edo’s higher utilisation rate did not translate into the largest AGO production because utilisation measures the proportion of a refinery’s available capacity being used, while production reflects the actual volume produced.
Aradel’s 0.31 ML/D AGO output accounted for the largest share of the combined production, followed by WalterSmith’s 0.28 ML/D. OPAC and Edo contributed 0.11 ML/D and 0.08 ML/D respectively.
On domestic AGO receipts, Aradel accounted for 0.33 ML/D of the combined 0.79 ML/D, followed by WalterSmith at 0.29 ML/D, OPAC at 0.09 ML/D and Edo at 0.08 ML/D.
Duport Refinery, which was listed as shut down, did not record production or domestic AGO receipts during the period.
The August assessment therefore covered four operating modular refineries and one non-operating facility. Edo led the operating group on capacity utilisation, while Aradel recorded the highest AGO production and domestic receipts.
The data provide a snapshot of the differing operating levels and output volumes across Nigeria’s modular-refinery segment in August 2026.
