Preparing your power solutions...
Ensure your operations, machines, and customer commitments remain uninterrupted with a robust backup power architecture that's scalable, reliable, and cost-aware. PowerVision's diesel generator systems provide seamless switchover, sufficient runtime, and proven ROI for businesses across Pakistan.
Backup power means automatically switching your business over to a reliable alternate source — typically diesel or hybrid generator systems — whenever grid supply fails.
Minimal downtime with automatic transfer switches
Sufficient capacity to cover outages until grid restores
Adequate power for critical loads with growth margin
Optimized consumption with maintenance forecasting
Clear ROI through avoided downtime losses
Protect revenue and customer commitments
In Pakistan, where outages are frequent, businesses need to know: How long will this system protect me? What value do I save by staying online?
| Factor | Why It Matters | Special Notes for Pakistan |
|---|---|---|
| Load profile (critical vs non-critical) | Only critical loads should be backed up to optimize generator size | Hospitals, industries have peaks & idle periods |
| Switchover / ATS speed | Delays damage sensitive equipment | Aim for ≤ 0.1 – 0.5 seconds transfer |
| Fuel availability & logistics | Diesel delivery & storage in remote/urban zones | Plan for local supply, fuel quality, buffer |
| Capital vs operational cost tradeoff | Bigger genset costs more but may save downtime losses | Model ROI over 3–5 years |
| Emissions, noise & compliance | Urban areas enforce noise & emission limits | Euro 5, soundproof enclosures matter |
| Redundancy / N+1 design | If one unit fails, others must carry load | Especially for mission-critical operations |
| Maintenance & support | Downtime in servicing is also "failure" | National service network, AMC, spare availability |
| Power factor & efficiency | Poor power factor wastes capacity | Use PF ~0.8 (common for industrial loads) |
How a precision manufacturing plant in Lahore saved PKR 130.16 Million annually with PowerVision backup power
A precision manufacturing plant in Lahore, producing high-value components, experienced on average 4 hours of power outages per week (spread in two outage events). During outages, production halted, machines idled, labor waited — costing raw material spoilage, missed shipment windows, overtime, and customer penalties.
Before backup:
4 hr/week × PKR 695,000 = PKR 2.78 Million/week lost
≈ PKR 144.56 Million/year
The plant needed a backup power solution that could:
PowerVision installed a Lister Petter SA G-Series 500 kVA backup generator with:
After installing backup power:
Net Benefit:
Avoided loss – Operating cost
= PKR 144.56M – (PKR 10.41M + PKR 1.39M)
= PKR 132.76 Million annual benefit

This calculator provides estimates based on typical scenarios. For real-time values, detailed analysis, and customized solutions, our Power Engineers and Experts are available for quick consultation.
Keep manufacturing, services, or operations running even during grid failure with seamless automatic switchover.
Avoid the high cost of halted production, missed orders, and reputational damage with continuous power availability.
When sized well, backup systems pay for themselves via avoided losses — often with payback in 6-24 months.
Modular backup allows growth from 10 kVA to several MW without complete redesign, protecting your investment.
Urban projects often require noise, emissions, and redundancy compliance — backup systems cover that with Euro 5 certification.
Redundancy, switching systems, and maintenance plans ensure you're never "caught" in blackouts with 24/7 support.
