Dumsor taught Ghana to own generators. The next lesson is knowing what they cost.
Every Ghanaian operation remembers the dumsor years — cocoa processors halting lines two days a week at the worst, and every serious factory buying its own generation. The grid is better; the reflex remains, and industrial power still costs real money (figures around $0.23/kWh are commonly cited). What most sites still lack is the picture: when the grid actually failed, whether the genset took the load, where the diesel went, and what a produced unit costs on grid versus generator. That picture is what addanode builds.
Three power problems Ghanaian operations recognise.
Nobody can say what the last outage cost
Without a timestamped record of grid failures, changeover delays and what each line lost, "power problems" stay an anecdote in the morning meeting. An outage log per site — grid state, changeover time, production impact — turns the ECG conversation, the insurance conversation and the solar business case into arithmetic.
Diesel spend that can't be audited
Fuel is bought in cedis and burned in assumptions. Tank telemetry plus run-hours gives you litres-per-hour against load, verifies every refill against the delivery note, and catches the sharp overnight drop that means theft — the day it happens, not at month-end.
Standby sets that fail the changeover
A genset that sat untested since the last outage fails on starter batteries, stale fuel or a service overdue in unlogged run-hours. Monitoring watches battery voltage, start events, run-hours toward service and load — so the set is a known quantity before the lights flicker.
Fitted to Ghanaian power reality.
- The tariff makes efficiency the first project. At industrial rates commonly cited near $0.23/kWh, energy metering per line often finds the cheapest capacity a factory owns: waste. Compressors idling weekends, cooling fighting open doors, peak-time loads that could shift — the meter finds them before any generator discussion.
- Dumsor memory shapes buying. Many sites carry more standby capacity than they use — unmonitored. Run-hour and load data shows whether the fleet is right-sized, which set to run for which load, and when a battery/solar hybrid quietly beats diesel for the small hours.
- Tema and the estates run on shared infrastructure. Factories in industrial enclaves see voltage events that trip sensitive lines even without a full outage. Per-phase quality logging separates "ECG event" from "our switchgear" — ending a class of arguments.
- Your gensets stay as they are. Controller ports (Modbus) where available; retrofit clamps, level senders and changeover contacts where not. No controller swaps, no warranty fights — and buffering keeps the record intact through the very outages being measured.
Dumsor history and tariff figures come from published Ghanaian reporting. The build pattern is our load-shedding-hardened power telemetry from Southern Africa, applied to Ghanaian sites.
One gateway per site, four questions answered.
1 · Grid
Per-phase presence and quality; every outage, sag and restoration timestamped into a site interruption log.
2 · Genset
Run status/hours, start success, battery voltage, temperatures and load per set — controller-read or retrofit.
3 · Fuel
Tank levels, consumption curves, refill verification, sharp-drop theft alerts across day tanks and bulk storage.
4 · Cost
kWh per incomer and line, grid vs generator, cedis per shift or per unit — exportable for finance and the energy audit.
Single sites go live in 1–3 weeks on the addaNet platform — the same dashboard as production monitoring, so power cost lands next to output, where it belongs.
Ghanaian power reality on one table
| Fact | What it does to a plant | What the gateway logs |
|---|---|---|
| Industrial tariff around US$0.23/kWh | Energy is a competitive cost line, not a utility bill | kWh per unit of output, per line |
| "Dumsor" — the load-shedding cycles Ghana has lived through | Every plant keeps gensets; every outage is a restart | Mains presence, outage duration, restart time |
| Prepaid electricity via mobile money | Consumption is visible in credit, not in cause | Load per line against the prepaid burn |
| Generator fuel and run-hours | One of the largest operating costs on many sites | Genset state, fuel level, run-hours, load |
Where power visibility pays in Ghana.
Manufacturers — Tema, Accra and Kumasi plants tracking energy cost per line and protecting sensitive processes from voltage events · Cocoa and food processors — the sector that carries dumsor's scars, where changeover speed decides whether a batch survives · Cold chains — depots and exporters for whom an unnoticed outage is a written-off consignment · Multi-site operators — banks, telecoms and fuel stations running genset fleets nationwide · Water schemes — systems whose pumps and loss-monitoring records both depend on power continuity.
Generator & power monitoring in Ghana — common questions
Is dumsor still a reason to invest in monitoring?
The investment case today is broader than blackouts: at Ghanaian industrial tariffs, energy waste and generator inefficiency cost money every normal day. The outage record then makes the resilient-power decisions — fleet size, solar, batteries — evidence-based whenever grid stress returns. Monitoring pays in calm years and earns double in bad ones.
Can you monitor any generator brand?
Yes. Modern controllers are read over Modbus; older sets get retrofit sensing — current clamps, run-state, battery voltage, tank senders. The monitoring is vendor-neutral, so your supplier relationships and warranties stay untouched.
How does fuel theft detection work?
Consumption follows a smooth curve matched to run-hours and load; theft is a sharp drop, usually while the set is off; a leak is a slow steady loss. Continuous level telemetry distinguishes the three signatures and alerts with timestamps — turning a month-end mystery into a same-day incident.
What does self-generated power really cost per kWh?
Litres burned, kWh produced and maintenance hours combine into a true generator cost per kWh, set against your grid tariff. Most sites discover their small-hours generator running costs multiples of grid power — which is exactly the load that batteries or scheduling should take.
What does a deployment cost in Ghana?
A single site is a gateway plus the sensors your sets need, quoted as a written cost band after a free remote review of your genset list. Fleets phase site by site. One caught theft, one avoided failed changeover or one right-sized fuel contract typically covers a site's monitoring.
Can it run alongside our production monitoring?
It's designed to. Power and production share gateways and one dashboard, so kWh per unit and downtime-due-to-power appear beside OEE — see OEE software for Ghanaian factories. The overlap is where the best savings hide.
