HESCO Rates Are the Same NEPRA Schedule as Every Other Ex-WAPDA DISCO
The tariff a HESCO customer pays comes from NEPRA's single notified schedule, shared identically with the other 9 ex-WAPDA companies (LESCO, IESCO, FESCO, GEPCO, MEPCO, SEPCO, PESCO, QESCO, TESCO) — only K-Electric in Karachi sits outside it with its own rates. Hyderabad Electric Supply Company itself is responsible for Hyderabad, Mirpurkhas, Tando Adam and the surrounding lower-Sindh districts. HESCO's territory sits in Sindh's mango- and sugarcane-growing belt, so its Agriculture tariff category (tube wells and SCARP connections) carries more weight here than on a mostly-urban DISCO's bill mix.
What surprises most first-time readers of this bill: it isn't telescopic like income-tax brackets are. HESCO bills every one of your entire month's units at the rate of the slab your total lands in, not just the units past the line. A 1 kW Unprotected connection at 300 units (Rs 33.10/unit) comes to roughly Rs 12,285 — cross to 301 units and Rs 36.46/unit applies to the whole month, roughly Rs 13,592.
How Protected / Unprotected / Lifeline Status Works
The classification isn't a one-time choice or a single-month snapshot — it tracks your usage pattern over several months:
- Lifeline: 12-month average consumption ≤100 units — the lowest rates (Rs 3.95–7.74/unit), exempt from fixed charges, but no slab benefit if you exceed 50 units in a month.
- Protected: 6-month average consumption ≤200 units — subsidised rates (Rs 10.54–13.01/unit) with the benefit of one previous slab.
- Unprotected: everyone else — full tariff rates from Rs 22.44/unit up to Rs 47.20/unit above 700 units.
HESCO tracks your consumption history and prints your assigned category directly on your bill — this calculator can't work that out for you, so select whichever category actually appears on your bill.
What Else Gets Added to the Bill
- Fixed Charge: billed per kW of sanctioned load (residential Protected/Unprotected use the full load; Time-of-Use residential uses 50% of load; Commercial/Industrial/Agriculture kW-based tariffs use 25% of load or actual maximum demand, whichever is higher) — or a flat per-consumer amount for smaller commercial/industrial categories.
- FPA (Fuel Price Adjustment): a monthly per-unit true-up of actual vs. assumed fuel cost — can be negative (a credit) when fuel prices fall.
- QTA (Quarterly Tariff Adjustment): a separate quarterly true-up for capacity, O&M and other system costs, revised every three months.
- Electricity Duty: a provincial tax on the subtotal, typically around 1.5% — check your bill for the exact figure.
- GST: 18% general sales tax applied to the subtotal.
- TV Fee: a flat PTV licence fee (commonly Rs 35) included on most domestic bills.
⚠️ This is an estimate, not your official bill. FPA, QTA, duty and GST figures change monthly/quarterly — always check your latest HESCO bill for the exact figures and customize them in the calculator above.
How to Use This HESCO Bill Calculator
This HESCO online bill calculator works entirely in your browser — no account, no uploading your actual bill, just the four inputs below.
- Step 1 — Category: pick the exact category printed on your bill (Lifeline, Protected, Unprotected, Time-of-Use, Commercial, Industrial or Agriculture).
- Step 2 — Units: enter the kWh figure from your last meter reading.
- Step 3 — FPA: enter the Fuel Price Adjustment figure from your last bill — it changes monthly and can be negative.
- Step 4 — Fine-tune: open "Customize" to adjust GST, Electricity Duty, QTA or TV Fee if your bill shows different values.
The Slab Cliff in Numbers — Protected vs Unprotected
Estimated total bill (1 kW sanctioned load, single phase, default duty/GST, FPA and TV fee excluded) at each unit level:
| Units | Protected Rate | Protected Bill | Unprotected Rate | Unprotected Bill |
|---|---|---|---|---|
| 100 | Rs 10.54 | Rs 1,498.53 | Rs 22.44 | Rs 3,010.20 |
| 200 | Rs 13.01 | Rs 3,467.89 | Rs 28.91 | Rs 7,267.99 |
| 300 | Rs 13.01* | Rs 5,022.59* | Rs 33.10 | Rs 12,284.60 |
| 301 | Rs 13.01* | Rs 5,038.13* | Rs 36.46 | Rs 13,592.48 |
| 500 | Rs 13.01* | Rs 8,131.97* | Rs 38.95 | Rs 23,870.13 |
| 700 | Rs 13.01* | Rs 11,241.36* | Rs 41.85 | Rs 35,814.15 |
*The Protected tariff table only defines slabs up to 200 units — a real Protected consumer averaging over 200 units for 6 months would be reclassified as Unprotected, so these rows are illustrative of the rate structure, not a realistic bill for that consumer. Notice the Unprotected jump from 300→301 units: about Rs 1,308 for one extra unit, purely from the slab-cliff mechanic. Figures verified against a real IESCO bill and this page's own calculator, which excludes TV fee (Rs 0) by default — add it in "Customize" if your bill shows one.
Frequently Asked Questions
Are HESCO's electricity rates set independently, or shared with other DISCOs?
Shared — NEPRA issues one uniform tariff notification covering all 10 ex-WAPDA distribution companies, HESCO among them, so the rate per unit is identical across the group. K-Electric, serving Karachi, sits outside this notification with a tariff structure of its own.
Why did a small rise in units cause a large rise in my HESCO bill?
Residential billing here is non-telescopic — once your total crosses a slab line, the higher rate is applied to the full month's units, not only the ones above the line. At 300 units on the Unprotected rate (Rs 33.10/unit) the bill lands near Rs 12,285; 301 units crosses into Rs 36.46/unit and the total jumps to roughly Rs 13,592.
What determines my Protected, Unprotected or Lifeline status with HESCO?
Your average consumption over time, not a single bill's units — 200 units or under averaged across 6 months earns Protected status, and 100 units or under averaged across 12 months earns Lifeline. HESCO maintains that history and prints the current status on your bill, so use whichever category is shown there.
Is FPA on a HESCO bill always an added cost?
Not always — FPA reconciles the fuel cost the tariff planned for against the fuel cost actually incurred that month, applied with about a two-month delay. If actual fuel costs undershoot the plan, FPA comes out negative and credits the bill instead of adding to it. It moves monthly, so use the figure on your most recent bill.
Why does a fixed charge appear on my HESCO bill even in a near-zero-usage month?
The fixed/customer charge funds connection upkeep and is billed against your sanctioned load in kW, unrelated to actual consumption (some smaller categories pay a flat per-consumer amount instead). Lifeline consumers don't pay this charge but face a minimum monthly bill in its place.
Base tariff data sourced from NEPRA's official Tariff Guide (S.R.O 279(I)/2026, February 2026), notified uniformly for all ex-WAPDA DISCOs including HESCO. FPA/QTA/GST/Electricity Duty change monthly or quarterly — verify against your own bill before making financial decisions.
