HESCO Electricity Bill Calculator
Estimate your HESCO bill under NEPRA's uniform national tariff, including the protected-consumer cliff, current QTA, FPA, duty and GST
Frequently Asked Questions
Electricity tariffs for the ten ex-WAPDA distribution companies — LESCO (Lahore), IESCO (Islamabad/Rawalpindi), MEPCO (Multan), FESCO (Faisalabad), GEPCO (Gujranwala/Sialkot), PESCO (Peshawar), HESCO and SEPCO (Sindh), QESCO (Quetta/Balochistan), and TESCO — are set uniformly by NEPRA under a national tariff policy, then layered with a Quarterly Tariff Adjustment and monthly Fuel Price Adjustment that change on their own separate schedule.
Why your bill changes even when your usage doesn't
NEPRA's base tariff is only the starting point — the Quarterly Tariff Adjustment (QTA) revises rates roughly every three months based on the DISCOs' actual cost of service, and the monthly Fuel Price Adjustment (FPA) passes through changes in the fuel cost of generation almost every single billing cycle. This is exactly why a household using the identical number of units two months in a row can still see a meaningfully different bill — the per-unit rate itself moved, not just the consumption.
The protected-consumer cliff that catches people off guard
Below a certain monthly consumption threshold, households qualify for "protected consumer" status with lower per-unit rates — but crossing that threshold, even by a small margin in one particularly hot month, can shift the entire bill (not just the units above the threshold) onto the higher non-protected tariff structure, depending on the specific slab design in force. This single-month usage spike effect is one of the most common sources of "why is my bill suddenly so much higher" confusion.
How this connects to your other calculations
If a large share of your bill is driven by specific appliances (air conditioners especially), the Appliance Electricity Calculator breaks down which devices are actually driving the rupee total. And if you're considering going partly off-grid, the Solar System Size Calculator and Solar Payback Calculator both use this same NEPRA tariff data to model realistic savings under the current net billing rules, not outdated net metering assumptions.
Common mistakes
Consumers often compare their bill to a neighbor's or a previous year's bill without accounting for the QTA/FPA adjustments that moved in between — the per-unit rate itself is not static, and comparing consumption-only, ignoring that the rate changed, produces a misleading conclusion about whether your actual usage went up.
