TCN refutes Kaduna Electric’s claim on Jos power supply

The Transmission Company of Nigeria has refuted claims by Kaduna Electric that a fault on the 330kV Jos transmission line contributed to reduced power supply across its franchise area.

In a statement on Thursday signed by the management of TCN, the company said all 330kV transmission lines connected to Jos were operational and transmitting bulk electricity.

TCN described Kaduna Electric’s claim as “false and a deliberate misrepresentation of facts,” saying there had been no disruption of bulk power transmission on any 330kV line supplying Jos since the restoration of the Jos–Lafia 330kV Line 2 circuit breaker.

The company explained that the circuit breaker was opened on August 23 for voltage control as part of a routine operation to maintain grid stability.

“For the avoidance of doubt, all 330kV transmission lines connected to Jos are in service and transmitting bulk power,” the statement said.

“TCN recorded a lone incident on 23rd August 2026 at 03:30hrs, when the Jos–Lafia 330kV Line 2 circuit breaker was opened for voltage control. This was a routine operational action to maintain grid stability.”

According to the transmission company, the line was restored at 11:59 pm on August 24 and had remained in service since then.

“There has been no outage or disruption of bulk electricity transmission on any 330kV line supplying Jos attributable to TCN since that restoration,” it added.

The development followed an announcement by Kaduna Electric on Wednesday attributing reduced power supply across its franchise area to lower load allocation.

The electricity distribution company had said the reduction was mainly due to an outage of one generating unit at the Shiroro Generating Station and a fault on the 330kV Jos transmission line.

Kaduna Electric said the fault had resulted in Shiroro supplying Jos and its surrounding areas instead.

The company also said that, based on the National Control Centre Daily Load Allocation for August 25, it received 104 megawatts, comprising 54MW from the Mando 330kV Transmission Station and 50MW from the Birnin-Kebbi axis.

It said it was working with TCN on the equitable distribution of available power and monitoring efforts to restore supply.

However, TCN urged Kaduna Electric and other stakeholders to verify information with the transmission company before making public statements on transmission-related issues.

“We urge Kaduna Electric and other stakeholders to verify facts with TCN before issuing statements that misinform the public and create unnecessary anxiety,” it said.

TCN also advised electricity customers in Jos and its environs to disregard what it described as the misleading information, assuring that it remained committed to ensuring stable and reliable bulk power transmission to distribution companies nationwide.
