POWERFIX PROTECTED
Lagos Businesses Cannot Afford Generator Downtime. Neither Can You.
Nigeria's unreliable grid means your commercial diesel generator is not a backup — it is your primary power source. The cost of unplanned downtime is measured in lost revenue, idle staff, spoiled stock and damaged client relationships.
₦500k+
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.
14 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 Lagos
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.
