Factory power and downtime monitoring in Nigeria — turn "we spend too much on diesel" into numbers.
Every Nigerian factory knows power is its biggest operational headache. Very few can put figures on it: generator hours per line, energy per unit produced, what each changeover costs in lost production, how the grid-vs-generator mix moved this quarter. addanode measures exactly that — for plants in Lagos, the Agbara–Ota–Sagamu corridors, Ibadan, Port Harcourt and Kano. (For the supply side — genset fleets, diesel tanks and fuel-theft detection — see generator monitoring; the two share one dashboard.)
Six power questions every Nigerian plant should be able to answer.
Generator runtime hours
How many hours did each set run this month, at what load, and how does that compare to its service schedule? Runtime and load trends turn generator maintenance from calendar guesswork into condition-based planning.
Energy and fuel per unit produced
Fuel spend divided by output — per line, per product, per shift. When energy per case on diesel days is visibly higher than on gas or grid days, scheduling energy-hungry products around supply becomes a decision, not a hunch.
Grid-vs-generator mix over time
What share of your kilowatt-hours came from the grid, the gas engine and the diesel sets — this week, this quarter, per feeder? The mix trend is the business case for every power investment you're considering.
Changeovers and their production cost
Every transfer between grid and generator is logged with its duration and what production lost while lines rode through or restarted. Multiply by frequency and you finally see what changeovers — not just outages — cost you.
Silent overnight outages in cold stores
A cold store that lost power at 2 a.m. and restarted at 5 a.m. looks fine at 8 a.m. — until the stock isn't. Continuous power-state and temperature monitoring raises a WhatsApp alert while there is still time to act.
Abnormal generator behaviour
A set running off-hours with no load, fuel level falling faster than runtime explains, a changeover that failed and left a line dark — pattern alerts flag the anomalies a logbook never catches.
Why this page exists only for Nigeria.
- Self-generation is the norm, not the backup. With grid supply unreliable and national grid failures reported repeatedly in recent years, most Nigerian factories run on generators or gas engines for much of the day. Each self-generated kilowatt-hour carries a heavy cost — which means measurement here pays back faster than almost anywhere else.
- Most plants meter the incomer, not the lines. One meter at the gate can't say which line, compressor or cold store is burning the diesel. Per-line and per-asset submetering is where "we spend too much" becomes "line 3 on night shift is the problem".
- Changeovers are frequent enough to matter. Grid-to-generator transfers happen daily on many sites. A transfer that drops a line for minutes, several times a day, is a larger annual loss than most breakdowns — but it only shows up if transfers are logged as events.
- The monitoring must outlive the blackout. addanode gateways are battery-buffered and log locally through total site blackouts, then back-fill when power returns. The blackout itself is recorded — start, end, what was lost.
Based on deployments across Southern Africa — where load-shedding taught us the same lessons — each configuration is adapted for Nigerian generator-first sites. Your own first month of data is the business case.
From fuel invoices to per-line power truth.
1 · Meter
Energy metering on the grid incomer, each generator set and key lines or assets; generator controllers read over Modbus; level sensors on fuel tanks; status contacts on changeover switches.
2 · Correlate
Power data joins production counts on addaNet: energy and fuel per unit, downtime per power event, cost of each changeover — per line and per shift.
3 · Alert
WhatsApp and email alerts on changeover failures, abnormal generator behaviour, off-hours running, fuel-level anomalies and cold-store temperature drift during outages.
4 · Report
A weekly power report your board can read: grid-vs-generator mix, generator hours and load, energy per unit by line, and the downtime Pareto split by power cause.
Battery-buffered, store-and-forward hardware throughout — pre-configured in Johannesburg, installed by local partners or your own electricians under our remote guidance, typically live within 2–6 weeks.
Six power questions, and the measurement that answers each
| Question | Measurement | Fact behind it |
|---|---|---|
| How many hours of grid did we actually get? | Mains presence, logged per minute | Grid supply around six hours a day is the working norm |
| What did each generator hour buy in output? | Genset load and run-hours against production counts | Manufacturers spent ₦1.34 trillion on self-generation in 2025 |
| Which line is the energy hog? | kWh per line, per shift | Energy is about 40% of operating cost |
| Is the Band A tariff worth the hours it promises? | Grid kWh at tariff vs genset kWh at fuel cost | Band A tariffs rose from ₦68 to above ₦200/kWh |
| Where did the fuel go? | Fuel level, refuelling events, litres per kWh | Fuel is the operating cost nobody reconciles |
| What did the last outage cost? | Restart time and lost counts per event | Restart losses are the largest unlogged downtime |
Who measures power first in Nigeria.
Energy-intensive plastics and packaging plants in Lagos and Ogun · FMCG and food factories along the Agbara, Ota and Sagamu corridors · cold stores and food distributors in Lagos and Port Harcourt · flour and feed mills near Apapa and in Kano · breweries and bottlers in Lagos, Ibadan and Port Harcourt. Power data pairs naturally with OEE and downtime monitoring on the same hardware, all on the addaNet platform — or start at the Nigeria overview.
Power & downtime monitoring in Nigeria — common questions
How do I measure diesel cost per unit produced?
Meter the energy each generator delivers and each line consumes, track fuel-tank level against runtime, and divide by the line's production count over the same period. addanode automates that chain — the result is a cost-per-case or cost-per-kg figure, per line and per shift, instead of one blended monthly fuel bill.
Can you detect a failed generator changeover automatically?
Yes. Status contacts on the changeover switch plus supply monitoring on both sides show every transfer — and every transfer that didn't complete. A failed changeover that leaves a line or a cold store dark raises a WhatsApp alert within moments, not at the next walk-round.
Can it catch an overnight power failure in a cold store?
Yes — that is one of the most common first use cases in Nigeria. Power-state and temperature are monitored continuously; if supply drops at 2 a.m. and temperature starts drifting, the on-call person gets a WhatsApp alert while intervention is still cheap.
Do we need to replace our generators or meters?
No. Modern generator controllers commonly expose Modbus, existing panel meters can usually be read directly, and where nothing digital exists, CT clamps and level sensors are added without touching the machine. Monitoring layers onto the power system you already run.
Does the monitoring itself keep working during a total blackout?
Yes. Gateways are battery-buffered and log to local storage through the blackout, then synchronise when power and connectivity return. The outage is captured as a time-stamped event — duration, affected feeders, production lost — not as a gap in the data.
Can it split grid consumption from generator consumption?
Yes. With metering on the grid incomer and on each generating set, every kilowatt-hour is attributed to its source. Over weeks that becomes your grid-vs-generator mix trend — the number that underpins decisions on gas engines, solar or captive-power contracts.
What does factory power monitoring cost in Nigeria?
A starter deployment — one incomer, one or two generator sets and a handful of lines — is quoted with a written cost band after a free remote assessment. Because the heaviest cost in Nigeria is the power itself, this is typically the fastest-payback monitoring a plant can install; we let your own data prove it.
