Efforts to address Nigeria’s recurring grid collapses could take at least three weeks, according to the Transmission Company of Nigeria (TCN), which identified three hubs—Shiroro, Jebba, and Ganmo—as key sources of recent issues.
The latest grid failures, on Tuesday and Thursday, marked the eleventh collapse this year.
TCN’s Executive Director of Transmission Services, Engineer Gbenga Ajiboye, said specialized equipment is being transported from construction sites nationwide to address abnormal frequency issues at the identified hubs.

TCN Public Affairs General Manager Ndidi Mbah attributed Thursday’s collapse to a surge in frequency caused by issues at a substation, leading to an emergency shutdown.
Mbah noted that ongoing projects include upgrades at the Jebba Transmission Substation and work on the 330kV lines along the Shiroro–Mando axis.
A recent report by an investigative committee has highlighted several grid vulnerabilities, prompting immediate technical and strategic interventions to improve grid stability.
TCN is implementing these recommendations to prevent further disruptions and address infrastructure damage from issues like vandalism.

Power Minister Adebayo Adelabu, who received the committee’s report, stated he will request supplementary budget funding for these critical upgrades.
Meanwhile, the Lagos State Government is seeking investors to develop up to 4GW of gas-fired power plants to reduce its dependence on the national grid.
The state currently receives only 2GW from the grid, far below its 6GW demand. The Lagos Ministry of Energy and Mineral Resources has designated four hubs for the construction of these plants, each expected to generate a minimum of 500MW.
