Operational data released by the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA) has shown that Edo Refinery recorded the highest capacity utilisation among Nigeria’s leading modular refineries in April 2026.
According to the NMDPRA April 2026 factsheet reviewed by Petroleumprice.ng, Edo Refinery operated at 79.20 per cent capacity utilisation during the month.
WalterSmith Refinery recorded 56.14 per cent utilisation, while Aradel Refinery posted 33.95 per cent capacity utilisation.
The report further showed that WalterSmith Refinery recorded the highest diesel production volume among the modular refineries captured in the data.
WalterSmith produced an average of 0.250 million litres of Automotive Gas Oil (AGO), also known as diesel, per day in April, with domestic supply averaging 0.254 million litres daily.
Aradel Refinery recorded average daily diesel production of 0.181 million litres and domestic supply of 0.213 million litres during the period.
Edo Refinery produced 0.086 million litres of diesel daily, while domestic supply stood at 0.092 million litres per day.
Combined supply from the three modular refineries averaged 0.559 million litres daily in April, according to the NMDPRA data.
Industry analysts said the figures reflect the continued role of modular refineries in supporting domestic diesel supply despite their relatively smaller output compared to large-scale refining facilities.
The report also showed that domestic refineries collectively achieved an average capacity utilisation of 99.12 per cent in April, with Dangote Refinery operating at 100 per cent capacity utilisation for most days during the month.
Analysts noted that while modular refinery operations continue to expand gradually, output levels remain modest relative to Nigeria’s broader fuel demand and large-scale refining capacity.
Industry stakeholders added that modular refineries remain important within Nigeria’s refining landscape, particularly in supporting regional fuel availability and improving domestic refining participation.
