Load shedding remains one of the biggest operational challenges for Pakistani manufacturers. Even with improvements in recent years, unexpected outages still cause significant production losses, equipment damage, and quality issues. This guide covers practical solutions for keeping your factory running.
Understanding the Cost of Load Shedding
For a typical mid-sized factory, each hour of downtime costs between PKR 500,000 and PKR 5 million depending on production value and restart time. A single unplanned outage can cost more than a year of preventive infrastructure investment.
Solution 1: Industrial UPS Systems
Uninterruptible Power Supply systems provide instant backup power for critical loads like control systems, PLCs, computers, and safety equipment. Modern industrial UPS systems deliver clean power within milliseconds of an outage, preventing equipment crashes and data loss.
Solution 2: Diesel Generators with ATS
Automatic Transfer Switches detect grid failure and start your generator within 5-15 seconds. This is fast enough for most production equipment but not for critical computer systems. Combine with UPS for complete coverage.
Solution 3: Hybrid Solar + Battery
Modern solar systems with battery storage can bridge shorter outages and dramatically reduce generator fuel consumption. For factories with roof space, solar also reduces baseline electricity costs.
Solution 4: Grid Stability Infrastructure
Some factories invest in power conditioning equipment including voltage stabilizers, harmonic filters, and automatic voltage regulators. These protect equipment from the voltage fluctuations that often accompany load shedding.
Sizing Your Backup System
Proper sizing requires analyzing critical loads, acceptable downtime, and budget. A professional energy audit identifies which loads need instant backup, which can tolerate 15-second delays, and which can be shut down safely.
Cost Overview
Backup power systems in Pakistan cost: - Industrial UPS (100 kVA): PKR 3-8 million - Diesel generator (500 kVA): PKR 8-15 million - Hybrid solar + battery (100 kW): PKR 15-25 million
Most factories need a combination of solutions.
