Accountability-centered maintenance means every job is photographed as it happens — not just written up afterward. A sample of recent PowerFix fieldwork across Lagos.
Nigerian Businesses Cannot Afford Generator Downtime. Neither Can We.
₦300k+
Lost revenue per hour of downtime
For a mid-size manufacturing plant or hotel, every hour the generator is down translates directly to lost production and idle labour costs.
3–5×
Reactive repairs cost more than scheduled maintenance
Emergency callouts, overnight parts sourcing and rushed labour inflate costs dramatically. A commercial diesel generator service Nigeria AMC prevents this entirely.
9 Months
Average gap between services for uncontracted generators
Industry data shows most commercial generators in Lagos go over a year without a certified service — a primary cause of premature engine failure.

Industry Verticals We Power Across Nigeria
PowerFix serves the commercial and industrial sectors that depend most heavily on uninterrupted diesel generator power. Our AMC contracts and emergency response protocols are tailored to the specific operational and compliance requirements of each industry.
Manufacturing & Industrial Plants
Rotary furnace operators, bottling plants, food processing facilities, metal fabricators and print manufacturers across Ilupeju, Ikeja, Apapa and Ogba industrial estates depend on uninterrupted generator power. Production stoppages trigger contractual penalties, spoilage and staff overtime costs that dwarf the price of a quarterly maintenance contract.
Typical fleet: 200–1,000 KVA · Multi-unit parallel configs
Corporate Real Estate & Estate Management
Commercial property managers, gated residential estates and office tower operators across Victoria Island, Lekki Phase 1, Ikoyi and Oniru manage generator fleets that demand a single accountable maintenance partner. PowerFix's Enterprise Power Uptime Contracts provide one SLA, consolidated invoicing and a dedicated account manager — designed specifically for procurement-led organisations.
Multi-site contracts · Single SLA · Fleet condition reports
Healthcare — Hospitals & Clinics
Private hospitals, surgical centres and dialysis clinics operate life-critical equipment that demands zero-downtime power. PowerFix understands the compliance, NAFDAC and SON documentation requirements faced by healthcare facility managers. Our load bank testing service certifies generator readiness to the standards required for medical facility accreditation in Lagos.
Priority SLA contracts · Load bank certification · ATS testing
Hotels & Hospitality
Boutique hotels and guest houses across Lagos Island, VI and Lekki know that a single power failure during peak occupancy translates directly into negative reviews and lost repeat bookings. PowerFix quarterly AMC contracts keep hotel generators primed through low-season periods so they perform without fault when occupancy peaks.
Flexible scheduling · Minimal operational disruption
Cold Storage & Agro-Processing
Abattoirs, fisheries cold rooms, pharmaceutical cold chain facilities and supermarket distribution warehouses cannot afford even a one-hour generator outage. PowerFix installs temperature-triggered generator monitoring and provides 4-hour emergency response SLAs for cold storage operators across Apapa, Ojota and Mile 2.
4-hour emergency SLA available · 24/7 contact line
Telecom Towers & Data Centres
ISPs, telecom tower operators and data centre facilities in Lagos operate generators across distributed sites. PowerFix offers scheduled preventive maintenance rotas, remote fault reporting and fleet-level condition tracking — reducing fuel waste and preventing the engine failures that cause SLA breaches and regulatory exposure.

Client names are withheld where confidentiality is requested. Technical details and outcomes are reported exactly as they occurred.
500 kVA Kirloskar Generator | Metal Processing Plant — Ogijo, Ogun State
The Problem: Generator would not start. The client's previous technician had replaced the starter motor and issued a 12-month warranty on the part — but it failed again within a month. That technician then became unreachable, leaving the facility without a working generator and no warranty to fall back on.
What PowerFix Did: Rather than fitting another starter motor and hoping it held, our engineers carried out a full Root Cause Analysis. The investigation traced the real fault to a short circuit at the start button — the starter motor itself was never the problem. We replaced the starter motor, corrected the wiring fault at its source, and issued a fresh warranty.
The Outcome: The fault has not recurred. PowerFix follows up with the client periodically to confirm the generator is still performing as expected.
Almost 12 months on, still fault-free — with no repeat failure of the kind that ended the previous technician's one-month warranty.
40 kVA Mikano SP40 Generator | Biscuit Manufacturing Plant — Ilupeju
The Problem: Generator had not been certified-serviced in 11 months. Black smoke on startup, chronic overheating, 40% above-normal fuel consumption. Production at risk of complete halt.
What PowerFix Did: Full on-site diagnostic. Engine oil drained and replaced to OEM specification. Air, fuel and oil filters replaced. Coolant system flushed and recharged. Injector timing verified. Load bank tested at 80% capacity for 45 minutes. Written condition report and photographic documentation issued same day.
The Outcome: Black smoke eliminated. Fuel consumption normalised within 3% of OEM baseline. Operating temperatures restored. Client enrolled on quarterly AMC contract immediately.
Client has completed five subsequent quarterly service cycles without incident. Zero unplanned downtime recorded.
250 kVA Cummins Generators | Victoria Island Commercial Building — 2 Units
The Problem: Estate management company managing a commercial building's two generators had them serviced by an informal technician — no documentation, no load testing, no ATS certification.
What PowerFix Did: Full on-site audit of both units in a single visit. Written condition report issued for each. One unit required immediate attention — AVR replacement and a coolant leak repair. Enterprise Power Uptime Contract established with quarterly scheduling for both units.
The Outcome: Both units certified and load-tested. Procurement team received a single contract document, single invoice structure and a dedicated PowerFix account manager.
Zero unplanned failures in 18 months since contract commencement.

Accountability-Centered Maintenance
Most generator problems in Nigeria don't start with the generator. They start with a technician who patches the symptom, collects payment, and leaves — until the same fault returns three weeks later, at double the cost. PowerFix was built to break that cycle. We don't just fix what's broken. We find out why it broke, document it, and make sure it doesn't recur.
Direct Engineers, Backed by a Vetted Network
The majority of jobs are handled by PowerFix's own directly-managed engineers. For specialist brands or overflow capacity, we call on a vetted partner network — either way, every job carries the same documentation, RCA methodology and warranty backing.
Root Cause Analysis — Every Job
We don't stop at "fixed." Every fault is traced to its source with a mandated RCA, so you're not paying to solve the same problem twice.

Same-day priority response for AMC clients, 24-hour mobilisation for new clients — because a fast response only means something when it's backed by a process, not luck.

Workforce Solutions
Need Reliable Generator Technicians and Operators? Let's Discuss.
PowerFix maintains an active pipeline of vetted, trained generator repair technicians and operators — the same standard of engineers who service our own AMC contracts. If your organisation has open technician roles or an under-resourced maintenance team, we place and manage the staff so you don't have to run the recruitment, vetting and payroll process yourself.
- Pre-vetted talent — candidates are screened against the same technical standard PowerFix holds its own engineers to.
- Technician stays on PowerFix's payroll — we handle recruitment, compliance, payroll and performance management; you pay a single ongoing rate.
- Full-time on-site or scheduled rotation — flexible engagement matched to your facility's workload.
- Seamless replacement — if a placed technician underperforms or leaves, PowerFix manages the swap-out from our existing pipeline, not a fresh search.
Who This Is For
- Facility and estate management teams with an unfilled generator technician role right now
- Manufacturing plants and hospitals expanding their in-house maintenance capacity
- Property portfolios that need a dedicated technician across multiple sites but can't justify a full internal hiring function
- Organisations that have tried informal or agency placements and been burned by inconsistent vetting
Have an open role advertised already? Tell us about it — there's a good chance a PowerFix-vetted candidate is already a fit.

"PowerFix took over our generator maintenance from an informal technician who kept patching symptoms. In 18 months, we've had zero unplanned downtime across both our Cummins units. The written reports alone saved us during our last ISO audit."
— Facility Manager
Commercial Building, Victoria Island
"We were burning 40% more diesel than spec on our 500 KVA set. PowerFix ran a root cause analysis, found injector fouling and a blocked air filter, and brought consumption back to baseline within a week. The fuel savings alone paid for the AMC."
— Operations Director
Manufacturing Plant, Ilupeju
"As an estate management company, we needed one accountable partner for generators across 4 sites. PowerFix's Enterprise contract gives us a single SLA, one invoice, and a dedicated account manager. Procurement finally stopped complaining."
