TCN restores 330kV Shiroro–Mando line to service
The Transmission Company of Nigeria (TCN) says it has restored the 330kV Shiroro–Mando Transmission Line 2 to service, completing repair works and returning a critical bulk power corridor to full operation after weeks of constraints that affected supply into parts of northern Nigeria. 
In an update credited to TCN’s General Manager, Public Affairs, Ndidi Mbah, the company said the line was re-energised at 8:32pm on Thursday, February 19, 2026, following “extensive technical interventions” carried out by its engineers. 
With that switch-back, TCN restores 330kV Shiroro–Mando line to service in the full sense, because both circuits are now available. TCN said “with both Line 1 and Line 2 now operational, the Shiroro–Mando 330kV transmission corridor is fully functional.” 
What exactly was restored and why it matters
The Shiroro–Mando corridor is a major transmission route that supports the movement of bulk electricity towards Kaduna Electric’s franchise area and surrounding load centres. When one circuit is down, the system loses redundancy and flexibility, which can translate into tighter supply margins and more fragile grid operations.
TCN’s position is that the restoration improves more than one thing at once. It said the return of the line “significantly enhances Kaduna Electric’s ability to transmit bulk electricity to its franchise area, improves network flexibility, and strengthens the overall reliability of the national grid.” 
So, TCN restores 330kV Shiroro–Mando line to service not just as a maintenance headline, but as a grid reliability update with direct consequences for power delivery.
A two-stage recovery: Line 1 first, then Line 2
This latest restoration follows the earlier recovery of Shiroro–Mando Line 1, which multiple reports said was restored at about 3:27pm on Saturday, February 14, 2026 after repair works by TCN engineers. 
At the time, TCN and other outlets noted that bringing back Line 1 eased supply constraints and improved bulk supply into Kaduna Electric’s network, while repairs continued on Line 2 to complete the redundancy. 
Now that Line 2 has also been re-energised, TCN restores 330kV Shiroro–Mando line to service with both circuits available again, which is the core difference between “improvement” and “full corridor functionality.”

What TCN says it achieved
TCN said the restoration process was executed with a focus on infrastructure integrity and operational reliability, with “strict adherence to safety and quality standards.” 
It also described the return of both circuits as “an important milestone” in its broader push to upgrade and strengthen Nigeria’s transmission infrastructure for more reliable supply across the network. 
Read plainly, the message is this: TCN restores 330kV Shiroro–Mando line to service and wants the public to see it as part of a steady, systems-level effort to build resilience into the national grid.
The human side: customers, disruptions, and expectations
Every transmission restoration story has a human underside: households adjusting to limited supply, small businesses burning more fuel, and communities struggling with unpredictability. In its statement, TCN thanked customers and stakeholders for patience during the outage period and reiterated commitment to a “more resilient and efficient national grid.” 
That gratitude is routine, but it also signals that the outage was felt widely enough to require reassurance.
And that’s where the public tension sits: as TCN restores 330kV Shiroro–Mando line to service, consumers will expect immediate improvement. But power quality still depends on the entire chain: generation availability, gas supply to plants, transmission stability, distribution infrastructure, and load management by DisCos. The restoration fixes a major transmission constraint; it does not, by itself, solve every local distribution weakness.
What this means for Kaduna Electric and grid stability
TCN’s clearest benefit statement in the latest update is its claim that the restored corridor enhances Kaduna Electric’s ability to wheel bulk electricity and improves grid reliability. 
In practice, having both 330kV circuits operational should provide better flexibility for system operators, reduce single-point vulnerability on that corridor, and improve the ability to manage faults without cascading disruption.
That is why TCN restores 330kV Shiroro–Mando line to service is not a minor engineering note. It is one of the levers that can reduce supply constraints and strengthen the grid’s ability to absorb shocks.
Bottom line
TCN says Line 2 was re-energised on February 19, 2026, and with Line 1 already back, the Shiroro–Mando 330kV corridor is “fully functional.”  That is the headline.
The next test is what consumers experience: whether supply stabilises in Kaduna Electric’s coverage areas and whether the national grid benefits from the added redundancy.
For now, the official position is clear: TCN restores 330kV Shiroro–Mando line to service, returns both circuits to operation, and says the national grid is stronger for it.
