Pakistan's electricity bills are regulated by NEPRA (National Electric Power Regulatory Authority) and distributed by DISCOs — LESCO (Lahore), MEPCO (Multan), IESCO (Islamabad), FESCO (Faisalabad), HESCO (Hyderabad), PESCO (Peshawar), QESCO (Quetta), and K-Electric (Karachi). The core billing system uses a slab structure: higher consumption = higher rate per unit for all units in that month.
| Monthly Units (kWh) | Rate per Unit (PKR) | Category |
|---|---|---|
| 1 – 100 | ~Rs 7.74 (lifeline / protected) | Protected |
| 101 – 200 | ~Rs 22.44 | Protected |
| 201 – 300 | ~Rs 29.89 | Unprotected |
| 301 – 400 | ~Rs 33.10 | Unprotected |
| 401 – 500 | ~Rs 38.29 | Unprotected |
| 501 – 600 | ~Rs 40.77 | Unprotected |
| 601 – 700 | ~Rs 43.94 | Unprotected |
| Above 700 | ~Rs 27.30+ (plus surcharges) | Unprotected |
Rates are base tariff — actual bills include FPA, FCS, taxes. NEPRA adjusts tariffs quarterly. Always verify at nepra.org.pk.
If you use 299 units, your entire bill is calculated at the 201–300 slab rate. Use just 1 more unit (300 total), and the rate jumps to the 301–400 bracket — applied retroactively to all 300 units. This means crossing a slab threshold can add Rs 2,000–3,000 to your bill in a single month. The best strategy: keep consumption just below 200 or 300 units when possible.
Three common reasons: (1) your FPA for that month was higher than last month, (2) you crossed a slab threshold by even 1 unit, or (3) you were reclassified from "protected" to "unprotected" category.
K-Electric operates under a slightly different regulatory framework in Karachi, with tariffs set separately. The base structure is similar but exact per-unit rates may differ. Check KE's official tariff or use a DISCO-specific calculator.
