Grid collapses have been attributed to a combination of technical faults, inadequate maintenance of transmission lines, and fluctuations in generation capacity.
The Grid recorded its second disturbance in 2026 on Tuesday, barely four days after the first occurrence, and weeks after a similar incident on December 29, 2025, which had caused widespread power outages across the country.

As of the time of filing this report, data showed zero megawatts of power supply to the 11 electricity distribution companies.
Electricity generation dropped sharply from over 4,500 megawatts to as low as 0 megawatts as of 11: 00 AM.
Checks showed that all 23 power generation plants connected to the grid reportedly lost output during the incident, resulting in zero power allocation to each of the 11 electricity distribution companies.
The Grid, however, in a post, while conversing with an X user, listed metering and grid expansion as part of the long-term panaceas to the constant system collapse.
“Metering is a huge part of the long term solution.
“Nigeria’s supply still depends on how much power is generated, transmitted, and how stable the grid is.
“So even with a meter, outages can still happen if there’s not enough electricity on the grid or if there are infrastructure failures.
“However, metering is a critical foundation for improved supply. When DisCos are properly paid for the electricity actually consumed, their revenues improve”, it said in part.
Metering, it said, reduces debt across the value chain.
“Also, customers stop paying estimated bills, which could be outrageous sometimes.
“The positives: GENCOs get paid, gas suppliers get paid, and maintenance improves.
“Over time, this creates the financial confidence needed to invest in transformers, lines, substations, and better customer service.
“Proper metering brings fairness, transparency, and trust then constant power comes later.
‘The grand is when metering is combined with grid expansion, better transmission capacity, gas availability, and strong regulation”, the Grid noted.
Although the grid currently generates about 5,000MW, former power minister Babatunde Fashola, at one time, said the facility has capacity for up to 12, 000MW.
Experts have noted that Nigeria requires well over 30, 000MW to attain power supply sufficiency for its more than 240 million population.
