The report highlighted that 2023 saw an increase in nationwide blackouts, notably on September 14, when a major transmission line caught fire, leading to the collapse of the power grid. This incident contributed to the overall tally of 46 grid collapses during the mentioned period.
According to the IEA, Nigeria has been consistently grappling with power failures, attributing the challenges to both aged infrastructure and incidents of vandalism affecting the grid.
The report further indicated that the deterioration of power infrastructure has resulted in a heightened reliance on backup generators, accounting for 40 percent of electricity consumption in Nigeria.
“Although the country has a total installed capacity of about 13 GW, average available capacity remained around 4.5 GW in 2023 due to a combination of factors such as deteriorating units, poor maintenance and liquidity constraints.
“Unreliable power supply due to limited grid infrastructure, underinvestment and ineffective regulatory frameworks have resulted in an estimated 40 per cent of all the electricity consumed in the country being produced from backup generators,” IEA declared.
It stated that natural gas accounted for around 75 per cent of electricity generated on the main grid in 2023 and would continue to play an important role in energy supply and grid stabilisation for Nigeria’s power sector until 2030, and decline by 2050, according to the country’s Energy Transition Plan.
“Renewables are also forecast to increase over the 2024-2026 period, at a compound annual growth rate of around eight per cent.
“Hydropower accounts for most of the renewables generation during 2024-2026, largely due to the completion of the Zungeru project, with an estimated generation of 2.6TWh per year.
“Solar PV is expected to grow rapidly, with an average rate of above 50 per cent per year over the next three years,” the report indicated.
