Overview
Updated YesterdayPower is back on at Abuja's Apo substation. The Transmission Company of Nigeria (TCN) restored supply by 4:08 p.m. on September 6, after crews fixed faults on two 132 kilovolt (kV) lines.
The planned outage, announced the day before, cut power to Lugbe, Garki, Area 1, National Hospital, Guzape, Asokoro and nearby areas. Crews latched optical ground wire (OPGW) on Apo Lines 1 and 2 between towers T130 and T132. It was the latest in a series of maintenance events at a substation serving much of Nigeria's capital.
Why it matters
The Apo substation feeds Abuja's hospitals, government districts, and homes. Every fault here risks outages for hundreds of thousands of residents.

Historical Context
2 moments from history that rhyme with this story — and how they unfolded.
Northeast Blackout (2003)
A sagging power line in Ohio touched a tree, tripped a generator, and set off a cascade that cut power to 55 million people across eight U.S. states and Ontario. Some areas went dark for up to four days.
Billions in economic losses and widespread disruption across the northeastern U.S. and Canada.
Led to mandatory grid reliability standards in the U.S. under the Federal Energy Reliability Commission.
Shows how a single transmission fault can ripple across a grid when infrastructure is aging and maintenance is deferred.
UK Blackout (2019)
A lightning strike and a generator fault cut power to about 1 million people in England and Wales, including parts of London. Rail networks and hospitals were affected for hours.
Power restored within hours, but transport was disrupted for most of the day.
The regulator ordered a review of frequency management and backup capacity across the grid.
Demonstrates that even well-maintained grids face transmission faults, and the speed of the response determines the public impact.
