Some power sector experts have expressed concern over the recurring collapse of the national electricity grid, urging the federal government to decentralize the country’s power infrastructure to improve reliability and efficiency.
The experts spoke in separate interviews with journalists in Lagos on Wednesday, following another nationwide blackout triggered by a system collapse on Tuesday.
The latest incident marked the second grid failure within a week, coming just days after a similar collapse.
It also coincided with the federal government’s signing of a N501.021 billion bond under the N4 trillion Power Sector Multi-Instrument Issuance Program, designed to settle legacy debts owed to electricity generation companies.
Data from the Nigerian Independent System Operator showed that power generation dropped to zero megawatts at about 11:00 a.m., plunging the entire country into darkness.
Electricity distribution companies in Benin, Eko, and Ibadan confirmed zero power allocation during the outage, disrupting economic and social activities nationwide.
The repeated failures have renewed concerns over the fragility of the nation’s electricity transmission infrastructure.
As of the time of filing this report, neither the Transmission Company of Nigeria nor NISO had issued an official explanation on the cause of the collapse or a timeline for full restoration.
Although electricity supply has gradually returned to some areas, the impact of the outage remains widespread.
Speaking on the development, an energy expert, Olukayode Akinrolabu, said the power sector requires urgent structural reforms, including grid decentralization, renewable energy integration, and market restructuring.
According to him, decentralizing the grid will empower states to regulate their electricity markets, attract private investment, and promote renewable energy solutions, such as solar mini-grids, thereby reducing dependence on fossil fuels.
Mr Akinrolabu noted that ongoing market reforms, including the establishment of NISO, were intended to improve operational efficiency and restore investor confidence, but stressed that more needed to be done.
“To stabilize the grid, the power sector should be segmented by states to allow for manageable power volumes and more effective system control,” he said.
Mr Akinrolabu, who also chairs the Customer Consultative Forum for Festac and Satellite Towns, called for the immediate upgrade of Supervisory Control and Data Acquisition systems for real-time monitoring, expansion of transmission lines, and rehabilitation of ageing infrastructure.
“The national grid has become technically complex due to its extensive connectivity, making it extremely difficult to manage,” he said.
He added that the Bola Tinubu administration could improve grid performance by investing in modern transmission infrastructure.
He advocated adopting a state-centric coordination model among power operators and strengthening sub-national regulatory enforcement to attract investment.
Cdon Adinuba, a communications consultant at Geometric Power Company, said Nigeria’s transmission network required massive investment, describing it as obsolete and poorly maintained.
Mr Adinuba observed that the grid frequently collapses whenever power generation exceeds 5,000 megawatts, leaving much of the country’s estimated 13,000 megawatts of installed generation capacity grossly underutilized.
He welcomed the federal government’s renewed interest in developing a second national grid, an idea originally proposed by a former power minister, Barth Nnaji, and approved by the Federal Executive Council in 2012.
According to him, the plan includes the construction of a 765-kilovolt super grid capable of transmitting significantly more power than the existing 330-kilovolt and 132-kilovolt transmission lines.
“The proposed grid will be regionalized, not along political or geopolitical lines, but as an operational necessity,” he said.
“It will function in segments so that faults can be isolated and resolved without shutting down the entire country, unlike the current system, where a minor fault triggers a nationwide blackout,” he added.
