The Transmission Company of Nigeria has rejected Kaduna Electric’s claim that a fault on the 330kV Jos transmission line contributed to reduced electricity supply across its franchise.
In a statement on Thursday, August 27, 2026, TCN said all 330kV lines connected to Jos were operational and transmitting bulk power.
TCN said the Jos–Lafia 330kV Line 2 circuit breaker was opened at 3:30 a.m. on August 23 for voltage control as part of routine grid-stability measures. It was restored at 11:59 p.m. on August 24 and had remained in service since.
The transmission operator said no bulk-power transmission outage had occurred on any 330kV line supplying Jos after the restoration.
The clarification followed Kaduna Electric’s statement on Wednesday, August 26, attributing reduced supply to lower allocation. The distributor cited the outage of one generating unit at Shiroro Generating Station and what it described as a fault on the Jos 330kV line.

Kaduna Electric said its allocation under the National Control Centre’s August 25 schedule was 104MW—54MW from Mando 330kV Transmission Station and 50MW from the Birnin-Kebbi axis.
The distributor said it was working with TCN to manage available power and improve supply.
TCN urged Kaduna Electric and other stakeholders to verify transmission-related information before making public statements, warning that inaccurate claims could mislead consumers.
The disagreement comes amid previous transmission challenges in northern Nigeria. In May, six towers on the Apir–Lafia 330kV corridor were vandalised, forcing both circuits out of service and prompting temporary supply to Lafia through the Lafia–Jos line.
TCN said the latest incident was different, stressing that the August 23 operation was a deliberate grid-management measure, not an unplanned transmission failure.
It advised consumers in Jos and surrounding areas to disregard claims linking the current supply reduction to a fault on its 330kV network.
