Egbin is down for maintenance. Why can one power station dim the lights in Lagos?
Egbin makes about a sixth of the grid's power, and it sits right next to Nigeria's biggest city. When it slows and lines into Lagos are damaged, Lagos feels it first, simply.
In 30 seconds
- Egbin, in Lagos, is Nigeria's largest thermal power station and supplies about 16 per cent of grid electricity, according to reports of the minister's statement.
- Part of it is down for planned maintenance, the Minister of Power says.
- Power made near Lagos does not need long lines to reach Lagos. Power from far away does, and the minister says some of those lines were sabotaged.
- He says the first units should return within 48 to 72 hours of his Friday statement, in phases.
On Friday the Minister of Power, Joseph Tegbe, named planned maintenance at Egbin Power Station as one reason for poor supply in Lagos, Abuja and two other states. Read the news story. Why does one station matter so much?
Egbin is big
Egbin is in Lagos State. It is Nigeria's largest thermal power station, and it supplies about 16 per cent of the electricity on the national grid, Nairametrics and Nigeria Info reported in their coverage of the minister's statement.
So when part of Egbin stops, the whole country loses a noticeable slice of its power at once.
Why Lagos feels it first
Electricity loses some energy as it travels along lines, and long lines can only carry so much. Power made close to a city is the easiest to deliver there. Egbin is in Lagos, so a lot of what it makes is used in and around Lagos.
When Egbin makes less, Lagos needs more power from stations far away, through the big transmission lines. The minister says some of those lines were sabotaged, which "restricted the use of alternative routes". So Lagos lost nearby power and had fewer ways to bring in power from elsewhere.
Why maintenance is done at all
A big station has several units, a bit like a bus company with several buses. Each one needs servicing. Skipping maintenance saves power today but risks a sudden breakdown later, which is worse because nobody can plan for it. Station managers try to service units one at a time so the rest keep running.
The minister did not say how many Egbin units are down or how long the work will take.
The minister's timeline
Tegbe said the affected units will come back in phases, "with the first units coming back online within the next 48 to 72 hours". His statement was issued on Friday, 6 November. That puts the first returns between Sunday and Monday. Full supply may take longer, since gas shortages at other plants are also part of the problem.
What it means for you
If you live in Lagos, the next few days should bring some improvement as Egbin's first units return. If they do not, the government's own deadline will have passed, and it is fair to ask why. While supply is short, DisCos will keep switching feeders off in turns. Charge phones and power banks when the light comes, and avoid running heavy appliances all at once when it returns, because that can trip a weak transformer.
Words to know
- Unit
- One turbine and generator inside a power station. A big station has several, so it can run some while others are repaired.
- Planned maintenance
- Repairs and checks booked in advance, as opposed to a sudden breakdown.
- Transmission line
- The high-voltage lines on tall towers that carry power from stations to cities.
