Nigerians continued to grapple with elevated energy costs in May 2026, as year-on-year price increases for the country’s three primary fuels remained sharply elevated, according to reporting by Channels Television and This Day. Diesel recorded the highest surge, climbing 86.4% over the previous year, while petrol prices increased by 55% and kerosene by 37%.
The sustained inflation in fuel prices reflects ongoing structural challenges in Nigeria’s energy supply and distribution network. The absence of reliable domestic refining capacity continues to expose the economy to international crude price volatility and foreign exchange pressures. Despite the official deregulation of the downstream petroleum sector, intermittent supply shortages and logistical inefficiencies have contributed to price spikes. The 86.4% year-on-year increase in diesel costs, in particular, has significant implications for power generation, as many businesses and households rely on diesel-powered generators due to an unstable national grid.
Residential energy affordability has deteriorated in parallel. Kerosene, widely used in low-income households for cooking and lighting, saw a 37% annual price increase, limiting access for vulnerable populations. The 55% rise in petrol prices has similarly strained transportation costs, feeding into broader inflationary pressures across food, goods, and services. According to This Day, the elevated cost environment persisted into May 2026, indicating no near-term relief for consumers.
These energy cost dynamics underscore the urgency of policy interventions aimed at boosting domestic refining, expanding liquefied petroleum gas (LPG) adoption, and accelerating investments in renewable energy infrastructure. Without structural reforms, analysts warn that fuel price volatility will continue to disrupt economic stability and deepen energy poverty.
