The Transmission Company of Nigeria (TCN) has announced the full restoration of electricity supply to Kaduna State following the completion of emergency repairs on a critical high-voltage transmission line. The company confirmed that the 330 kV Shiroro–Mando Transmission Line 1 is now fully operational, alleviating recent power supply constraints in the state.
In a statement released on Monday, TCN’s spokesperson detailed that repair works on the line were concluded over the weekend. This restoration has directly improved bulk power delivery to Kaduna Electric, the local distribution utility, thereby steadying supply to consumers across the state. However, the company noted that maintenance activities continue on the adjacent 330 kV Shiroro–Mando Transmission Line 2, which remains out of service.
This localized recovery occurs against the backdrop of broader national grid instability. TCN highlighted that the country is still experiencing a general reduction in power generation and supply. The primary cause is ongoing maintenance at gas production facilities operated by Seplat, a joint venture including the Nigerian National Petroleum Company Gas Infrastructure Company (NGIC). Gas is a dominant fuel source for Nigeria’s thermal power plants, and disruptions to supply chain infrastructure directly impact national grid output.
The successful repair of the Shiroro–Mando Line 1 underscores the operational challenges inherent in Nigeria’s transmission network, where single points of failure can precipitate regional outages. For residents and businesses in Kaduna, the restoration marks a return to more consistent electricity after a period of deficit. Yet the simultaneous national shortfall, attributed to upstream gas infrastructure maintenance, illustrates the systemic interdependence between gas supply, power generation, and transmission.
While the immediate crisis in Kaduna has been resolved, the ongoing work on Line 2 and the nationwide gas-related generation shortfall signal that grid reliability remains fragile. TCN’s update provides a snapshot of the reactive maintenance required to maintain stability in an aged and stressed national grid. The situation also highlights the critical need for sustained investment in both transmission corridors and upstream gas infrastructure to achieve consistent power supply across Nigeria. The restoration in Kaduna offers temporary relief, but the persistent national deficit serves as a reminder of the extensive work needed to secure the country’s energy future.
