• Experts fault loss of industrial ‘anchor tenants’
Nigeria’s fragile electricity system suffered another major collapse yesterday after real-time grid data showed power generation plunging to 231.50 megawatts (MW), triggering widespread blackouts and leaving most electricity distribution companies (DisCos) without supply.
Data from the National Grid Performance Dashboard (NGPD) indicated that as of 5.00p.m., total generation on the national grid dropped to one of its lowest ever recorded, with only three generation companies (GenCos) supplying electricity nationwide.
However, some minutes after 9pm, the situation improved and generation reached 1,924.49MW. The recovery was driven largely by output from key hydro and gas-fired power plants. Kainji hydro power station led generation with 519MW, followed by Jebba hydro at 242MW, Olorunsogo NIPP at 109.20MW, Paras Energy at 108.20MW, Delta Power Plant at 128MW, Omotosho gas plant at 121MW, and Okpai gas/steam plant at 226MW.
Checks revealed that more than 30 grid-connected power plants, including critical stations such as Egbin, Geregu, Omotosho, Olorunsogo, Afam, Ihovbor, Sapele, Jebba, Kainji and Zungeru, were either completely offline or producing zero output. Only Delta power station, which generated 149MW, Okpai with 70MW and Omoku Gas Plant, with 12.50MW were operational at the time.
The sharp collapse in generation cascaded across, slashing electricity supply to DisCos. Data from the national grid’s Distribution Load Profile (DLP) showed that total load allocation stood at just 305MW by 17:16 p.m., an amount grossly inadequate to serve even a single major city.
Only six DisCos, viz Ibadan, Abuja, Benin, Eko, Enugu and Ikeja, received power allocations of 105MW, 40MW, 20MW, 45MW, 30MW and 65MW, respectively, while major DisCos recorded zero allocation, effectively cutting off millions of customers from the national grid.
Power sector analysts described the incident as a systemic failure, stressing that a national grid serving over 200 million people should not be operating at output levels comparable to a small independent power plant.
Experts explained that it was not just a technical disturbance, but a near-total shutdown of the generation ecosystem, as over 90 per cent of installed plants are simultaneously offline.
The latest collapse comes amid persistent gas supply constraints, mounting debts to GenCos, liquidity shortfalls and weak transmission resilience. Thermal power plants, which account for nearly 80 per cent of Nigeria’s installed capacity, continue to struggle with inadequate gas supply and unpaid invoices, while hydro stations face operational and water management challenges.
Despite having over 13,000MW of installed generation capacity, Nigeria’s actual available power has remained far below demand, with grid disturbances and collapses increasingly becoming routine.
The outage followed weeks of constrained electricity supply, including during the Christmas period, when average generation hovered around 3,000MW, far below national requirements. As previously reported by The Guardian, widespread outages had already affected Lagos, Abuja and other major cities, even before yesterday’s collapse.
Eko DisCo, however, confirmed the collapse in a notice to its customers on the restoration.
“Kindly be informed there was a system collapse at 14:01hrs, which resulted in a loss of power supply across our network. We are working with our partners as we hope for the speedy restoration of the grid. We will keep you updated as soon as the power supply is restored,” it stated.
For consumers, the collapse deepened frustration, coming amid rising electricity tariffs and expectations of improved service, particularly for customers migrated to higher tariff bands.
The latest collapse, occurring at a time of already depressed generation, underscores the precarious state of Nigeria’s electricity system and raises fresh questions about how soon promised stability can realistically be achieved.
Energy experts say the repeated collapse of the national grid is also linked to the steady exit of large industrial consumers often described as anchor tenants from the national electricity network, warning that grid stability will remain elusive unless they are reintegrated.
Executive Director of PowerUp Nigeria, Adetayo Adegbemle, had told The Guardian that the Federal Government must urgently reverse the trend of industries disconnecting from the grid, noting that their departure left residential consumers shouldering the financial burden of sustaining the power system.
“We have allowed the big guns to escape the national grid, pushing the load of sustaining it on to residential consumers. As a result, tariffs become more expensive for households, while producers and industries continue to seek alternative energy sources, though those alternatives are often more costly,” Adegbemle said.
