Project Background
In Lagos, Nigeria, a rapidly growing commercial data center serving fintech companies, e-commerce platforms, and cloud service providers faced a critical operational challenge. The national power grid in the region was notoriously unstable, with frequent outages lasting from minutes to several hours, and voltage fluctuations that could damage sensitive server equipment.
For a data center housing over 500 server racks, even a 30-second power interruption could result in massive data loss, service downtime for thousands of businesses, and significant financial penalties under SLA agreements. The facility needed a backup power solution that could activate instantly and sustain full operations for extended periods during grid failures.
The Challenge
- Location: Lagos, Nigeria — urban environment with strict noise regulations
- Grid reliability: 8-12 outages per month, voltage fluctuations of ±20%
- Critical load: 1,200 kVA for servers, cooling, and network infrastructure
- Transfer requirement: Less than 5 seconds to prevent server shutdowns
- Noise limit: Must comply with city noise regulations (70 dBA at 7m)
- Space constraint: Limited outdoor space in urban industrial zone
- Remote monitoring: Operations team needed real-time visibility from headquarters
Our Solution
MechVolt Power designed a compact, high-performance backup power system specifically for data center applications:
- Primary backup: 2 × 800 kVA Cummins-powered diesel generators in 40ft soundproof containers, configured for automatic parallel operation
- ATS system: Ultra-fast automatic transfer switch with sub-5-second transfer time, integrated with the data center’s UPS system for seamless power continuity
- Container design: Custom 40ft soundproof containers integrating generators, fuel tanks, cooling systems, and control panels — minimizing footprint and installation time
- Fuel capacity: 8,000-liter integrated fuel tanks providing 48 hours of full-load runtime
- Remote monitoring: Cloud-connected SCADA system with mobile app access, providing real-time status, fuel levels, maintenance alerts, and performance analytics
- Exhaust treatment: Industrial-grade silencers and catalytic converters meeting urban emission standards

Results
The backup power system has been operational for over 12 months, successfully handling more than 100 grid outages without a single instance of server downtime. The sub-5-second transfer time, combined with the data center’s UPS system, ensures that servers never experience even a momentary power interruption.
The remote monitoring system has proven invaluable for the operations team, who can monitor generator status, fuel levels, and performance metrics from their headquarters in real time. Predictive maintenance alerts have helped prevent potential issues before they occur, with the system achieving 99.9% availability.
The containerized design allowed for rapid installation — the entire system was commissioned within 3 days of delivery, minimizing disruption to the data center’s operations. The low-noise design has also ensured full compliance with local environmental regulations, with no complaints from neighboring businesses.
Client Feedback
“Power reliability is everything in our business. MechVolt’s containerized generator solution gives us complete peace of mind — we’ve had zero downtime since installation, and the remote monitoring lets us keep an eye on things even when we’re off-site.”
