The Problem: High Diesel Costs & Emissions

Pakistani businesses spend millions on diesel annually. With frequent grid outages, generators run for extended hours, driving up costs and carbon emissions.

The solution: BESS eliminates fuel costs for short outages (80% of all outages) and dramatically reduces generator runtime.

Telecom BTS Site ROI Example

Generator Only
  • Monthly diesel:PKR 80,000
  • Maintenance:PKR 15,000
  • Annual cost:PKR 1,140,000
With BESS + Generator
  • Monthly diesel:PKR 20,000
  • Maintenance:PKR 8,000
  • Annual savings:PKR 804,000
Payback period: 18-24 months

How BESS Works

Intelligent energy management for maximum savings

1

Grid Available

BESS charges from grid, load runs on grid power

2

Short Outage

BESS instantly takes over, no generator needed

3

Extended Outage

Generator starts only when BESS SOC < 20%

4

Grid Restored

BESS recharges, generator stops automatically
