TCN reveals reason for national grid collapse

The Transmission Company of Nigeria (TCN) said the national grid has been fully restored following what it described as a partial disruption that occurred at about 3:09pm on Saturday.

In a statement signed on Sunday by its director-general for public relations, Ndidi Mbah, TCN said the system failure was likely triggered by the unexpected shutdown of three units of the power plant.

This resulted in the sudden disconnection of 313 MW of power from the network, causing system instability and loss of supply to part of the national power grid, the statement said.

“The system disruption, which is resulting in three partial grid disruptions, including one total disruption this year, is suspected to have been triggered by the unexpected shutdown of three (3) power plant units, which resulted in the sudden disconnection of 313 MW from the grid, causing system instability, which in turn led to the loss of power to part of the national grid,” the statement read.

It added that “the system operator responded to the sudden drop in generation, which led to lower frequency, by creating a power island in a part of the network, comprising the Ibom power station, through which the company continued to supply power to Uyo, Aba, Itu, Eket, Calabar etc., even when the rest of the network was without power.

“Operators began work to restore the network immediately after the incident. Yesterday at approximately 9:57 p.m., the entire part of the network that was affected by today’s incident was successfully restored.”

It said a power grid failure had led to a power outage in the states and the Federal Capital Territory (FCT) of Abuja.

The first failure of the national power grid occurred on February 4, 2024, followed by a nationwide power outage on March 28, and another system failure on April 15.
