Battery storage in Karachi. Your business, your numbers.
Illustrative diesel-replacement scenario: at the NEPRA B2 off-peak reference of PKR 22.83/kWh (decision 2026-02-11) and OGRA HSD of PKR 389.8/L (2026-10-21, excluding secondary freight), each kWh of diesel backup replaced saves about PKR 91.57 after recharging. For 4 hours × 50 kW of backup, a 4-year simple payback requires an installed price at or below PKR 110,095/kWh nominal DC (PKR 25,753,293 total).
Scenario assumptions: 0.30 L/kWh fuel consumption; 100% existing diesel supply; 365 operating days/year; 90% round-trip efficiency and depth of discharge; 95% discharge efficiency; 2.5% annual capacity degradation; 6-hour grid charging window; zero maintenance, price growth and replacement costs; no arbitrage or production value. These are editable assumptions, not measured city averages. Current all-in bill rates and delivered diesel costs can differ. NEPRA · 2026-02-11 · OGRA · 2026-10-21

How long does a battery take to pay back in Karachi?+

Which electricity provider is used for Karachi?+
K-Electric is the provider used by this page’s reference dataset. Confirm your own utility and tariff category from your electricity bill before entering rates.
Can I replace my generator completely?+
Only if battery energy, continuous power and available recharge can meet your site’s needs. The calculator flags shortfalls; the daily model does not guarantee coverage for every outage.
What if I already have solar?+
Solar capacity alone does not establish available surplus or its opportunity cost. The first version uses grid charging; a solar-surplus scenario needs verified export rules and energy data.
