The Tansmission Company of Nigeria (TCN) has said that power generation dropped by 468 megawatts due to 330kv DC Ugwaji–Apir Double Circuit transmission lines 1&2 tripped causing power outage across Northern region of the country.
TCN announced the development in a statement signed by its General Manager, Public Affairs, Mrs Ndidi Mbah, on Tuesday, October 22, 2024.
She explained that “At approximately 4:53am, the Ugwuaji–Markurdi 330kV Line 2 tripped and 243 MW on that line was transferred to Line 1 on the same route. At 4:58am, Line 1 also tripped, resulting in a total loss of 468 MW. By around 5:15am and 5:17am Line 1 and Line 2 were tried, but they all tripped immediately on the same relay indication.
Mbah disclosed that two teams of linesmen were disparched following the tripping incidents, one from the Apir Transmission Sub-region and another from the Enugu transmission to expedite fault tracing along the 215 km route, which includes 245 transmission towers.
“Throughout yesterday, the Apir team patrolled the line, navigating challenging terrains in search of the fault, reaching as far as the River Benue. They were unable to locate the cause of the tripping and have continued in the fault tracing early this morning.
“Meanwhile, the lines patrol team from Enugu Region of TCN were unable to commence lines patrol yesterday due to the ‘sit-at-home’ directive in the South East for October 21st and 22nd, 2024. This hindered not only the patrol team but also made it difficult to refuel patrol vehicles for the long distance line trace. Arrangements were, however, made for security operatives to guide the team, who have commenced fault tracing this morning.
“Currently, TCN has restored supply to the 132kV transmission line from New Haven to Apir, but the 330kV lines remain out of service, impacting power supply in the Northern region of the country. Sadly, the TCN Shiroro-Mando transmission line is also down due to security reasons, causing power outage in the North,” the GM noted.
She assured that the company is making every effort to trace the cause of the outage to enable its engineers effect repairs and restore bulk power supply through both lines.
“We sincerely apologize to the government and electricity consumers in all the affected states and acknowledge that our patrol teams would have continued their search into the night yesterday, if not for the challenging terrain, which includes swamps and rivers, as well as insecure areas in the forest.
“We reconvened very early this morning with security operatives and have continued the fault tracing to locate and address the cause of the line tripping,” she said.
