Oworonshoki TR1 Restored, Supply Resuming


Good news arrived on Wednesday morning. TCN confirmed that its maintenance crew successfully restored the TR1 60MVA transformer at Oworonshoki Transmission Substation at exactly 07:53hrs on June 30, 2026 less than 24 hours after the flooding first knocked it offline.


The Ikeja Electricity Distribution Company (IKEDC) can now resume distributing power to customers in the areas that were affected by the outage.


TCN spokesperson Ndidi Mbah confirmed the restoration in an official statement.


✅ TR1 60MVA transformer at Oworonshoki — RESTORED as of 07:53hrs, 30 June 2026

⚠️ TR3 30MVA transformer at Oworonshoki — status not yet confirmed in this update

⚠️ Lekki 132kV substation — was still under stress as of yesterday's report. Monitor for further TCN statements.


What This Means Practically for Lagos Residents


Power is coming back to parts of the affected network, but this restoration is partial.


Only TR1 has been confirmed restored. TR3, the second transformer that tripped during the flooding — has not been mentioned in today's update, which means it may still be out of service or under assessment.


In practical terms:


Areas supplied through IKEDC from Oworonshoki should begin seeing power return, though distribution may take time to stabilise across the full network


The Lekki 132kV substation situation from yesterday's report has not been specifically updated, it was under stress but operational. Lekki and Oniru residents should continue to monitor


This restoration happened in under 24 hours, which reflects fast work by TCN's maintenance crew under difficult conditions


A second flooding event or continued heavy rainfall could disrupt supply again, the underlying vulnerability of the substation compound to flooding has not changed


The Bigger Picture Has Not Changed

The speed of this restoration is welcome. But what this week's events have demonstrated very clearly is how exposed Lagos residents and businesses are when even one substation goes down.


The grid has limited redundancy, and flooding events in Lagos are becoming more frequent and more severe during the rainy season.


If you sorted out your solar or inverter backup during this outage, you have made a decision that will pay off every time this happens again and it will happen again. If you have been meaning to act and have not yet, the window is still open.


Banex Mall solar and energy vendors are still in store.


Come in any time even with power partially restored, the conversation about backup power is worth having before the next outage, not during it.
