The Transmission Company of Nigeria (TCN) has confirmed that it is actively working to stabilize the national grid following a disturbance that occurred at 11:29 am on Thursday.
In a statement issued in Abuja, TCN’s General Manager for Public Affairs, Mrs. Ndidi Mbah, explained that the disturbance was triggered by a sudden frequency surge from 50.33Hz to 51.44Hz.
Recovery efforts were immediately initiated, with the Abuja region being restored within 28 minutes.
Mbah attributed the frequency spike to a malfunction at one of TCN’s substations, which was subsequently shut down as a precautionary measure to prevent further issues.
She also outlined ongoing repair and upgrade works at several critical transmission points to ensure grid stability.
“We are currently engaged in extensive repair works on key transmission lines and substations. This includes work on the 330kV transmission lines along the Shiroro–Mando corridor, major upgrades at the Jebba Transmission substation, and the restoration of the second Ugwuaji–Apir 330kV transmission line.” she said.
The General Manager also highlighted that, following an investigation into previous grid failures, TCN has begun addressing vulnerabilities identified within the transmission system.
The company is implementing a combination of technical upgrades and strategic interventions based on the findings from the investigative report.
“While these repairs are ongoing, we expect that some instability may continue until the major work is completed,” Mbah added.
“We ask for the public’s understanding and patience as we work through these challenges.”
Mbah reassured Nigerians that TCN remains committed to improving the reliability of the national grid, recognizing its crucial role in powering the country’s socio-economic development.
She also emphasized that efforts to address issues like vandalized transmission lines are part of the company’s broader strategy to ensure long-term grid stability.
