Project Background
A major electronics manufacturing plant in southern Vietnam, producing components for international automotive and consumer electronics brands, faced a critical vulnerability: the local power grid experienced frequent outages averaging 3-4 per month, each lasting from 30 minutes to several hours.
Even a brief power interruption could ruin entire production batches of sensitive semiconductor components, resulting in material losses worth tens of thousands of dollars per incident. The facility needed a backup power system that could seamlessly take over within seconds of any grid failure, while also handling the plant’s fluctuating load profile during peak and off-peak production shifts.
The Challenge
- Location: Industrial zone, Binh Duong Province, Vietnam
- Grid reliability: 3-4 outages per month, 30 min to 4+ hours each
- Critical load: 800 kVA for sensitive production lines and clean rooms
- Total facility load: 1,200 kVA including HVAC and auxiliary systems
- Transfer time requirement: Less than 10 seconds to prevent production loss
- Noise restriction: Must comply with industrial zone noise limits (65 dBA at property boundary)
Our Solution
MechVolt Power designed a tiered backup power system that prioritizes critical loads while maintaining overall facility operations:
- Primary backup: 1 × 1000 kVA Perkins-powered generator with ultra-fast ATS, dedicated to critical production lines and clean rooms
- Secondary backup: 1 × 500 kVA generator for HVAC systems, lighting, and administrative areas
- ATS system: Dual automatic transfer switches with less than 5-second transfer time for critical loads
- Enclosure: Ultra-quiet soundproof canopy (68 dBA @ 7m) to meet strict noise regulations
- Monitoring: Remote monitoring system with real-time alerts sent to facility management via SMS and email
Key Equipment Specifications
| Parameter | Primary Backup | Secondary Backup |
|---|---|---|
| Power Output | 1000 kVA standby | 500 kVA standby |
| Engine | Perkins 2806A-E18TAG3 | Perkins 1106A-E70TAG3 |
| Alternator | Stamford HC734 | Stamford UC274 |
| Transfer Time | < 5 seconds | < 10 seconds |
| Noise Level | 68 dBA @ 7m | 65 dBA @ 7m |
| Fuel Tank | 1,500 liters (8-hour runtime) | 800 liters (10-hour runtime) |
Results
Since installation, the backup system has activated automatically during every grid outage, with zero production losses attributable to power interruptions. The ultra-fast ATS transfer time ensures that sensitive production equipment never detects a voltage drop, maintaining uninterrupted operation of clean rooms and precision manufacturing lines.
The remote monitoring system has proven particularly valuable, allowing the maintenance team to receive instant notifications and track generator performance metrics in real time. Scheduled maintenance has been streamlined based on actual runtime data rather than fixed intervals.
Client Feedback
“Before MechVolt’s system, we were losing an average of $50,000 per month in damaged materials due to power interruptions. Since installation, we’ve had zero production losses. The investment paid for itself within the first three months.”
