From your bill's 'Total FPA' line — can be negative

SEPCO Rates Are the Same NEPRA Schedule as Every Other Ex-WAPDA DISCO
Pricing for SEPCO customers is decided at the federal level, not locally — the same NEPRA-notified tariff schedule governs it and all 9 sibling ex-WAPDA companies (LESCO, IESCO, FESCO, GEPCO, MEPCO, HESCO, PESCO, QESCO, TESCO), with K-Electric in Karachi as the single exception running its own rates. Sukkur Electric Power Company handles distribution across Sukkur, Larkana, Khairpur and Shaheed Benazirabad. SEPCO covers upper Sindh along the Indus — a mostly rural service area, which is why its Agriculture and Lifeline/Protected residential categories make up a larger share of connections than in Punjab's more urbanised DISCOs.
One thing worth flagging up front: this tariff is non-telescopic, the opposite of how income-tax brackets work. Rather than taxing only the units above a line at the higher rate, SEPCO re-bills your whole month once you cross into a new slab. A 1 kW Unprotected connection at 300 units (Rs 33.10/unit) totals roughly Rs 12,285; at 301 units, the entire month shifts to Rs 36.46/unit for roughly Rs 13,592.
How Protected / Unprotected / Lifeline Status Works
You can't opt into a category, and no single bill decides it either — it comes from a multi-month usage average:
- 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.
SEPCO 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.
Reading the Non-Energy Lines on a SEPCO Bill
Past the energy charge, a SEPCO bill stacks five more line items before you reach the total:
| Line item | What determines it |
|---|---|
| Fixed / Customer Charge | Per-kW of sanctioned load for residential and kW-based commercial/industrial tariffs (Time-of-Use uses half the load; larger commercial/industrial uses a quarter of load or actual peak demand, whichever is higher); a flat per-consumer amount for the smaller categories instead. |
| FPA | Actual vs. assumed fuel cost for the month, roughly two months behind — goes negative (a credit) when fuel got cheaper than planned. |
| QTA | A separate capacity/O&M true-up, revised once a quarter rather than monthly. |
| Electricity Duty | Provincial levy on the subtotal, around 1.5% — the exact figure is printed on your bill. |
| GST | Federal 18% sales tax on the same subtotal. |
| TV Fee | Flat PTV licence charge, usually Rs 35, bundled into most domestic connections. |
⚠️ Treat this as a planning estimate, not your official bill. These five figures move monthly or quarterly — pull the exact numbers off your latest SEPCO bill and plug them into "Customize" above for a closer match.
Using the Calculator in Four Steps
No sign-up and no bill upload — the SEPCO calculator above runs on four inputs, entirely in your browser.
- Category: match whatever is printed on your bill — Lifeline, Protected, Unprotected, Time-of-Use, Commercial, Industrial or Agriculture.
- Units consumed: the kWh reading from your latest bill.
- FPA: copy the Fuel Price Adjustment line from your bill; it can be a negative number.
- Customize (optional): override GST, Electricity Duty, QTA or TV Fee if your bill's figures differ from the defaults above.
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
Does moving from LESCO's or IESCO's territory into SEPCO's change what I pay per unit?
No. The rate card comes from NEPRA centrally, and it's the same for all 10 ex-WAPDA DISCOs — SEPCO included — so the same category costs the same per unit no matter which of the ten companies bills you. Karachi's K-Electric is the only company outside this shared schedule.
A few extra units pushed my SEPCO bill up by over a thousand rupees — is that normal?
Yes, and it's the non-telescopic slab design at work: the entire month re-rates once your total crosses a slab boundary, rather than only the units past it. Unprotected at 300 units (Rs 33.10/unit) runs about Rs 12,285; step to 301 units and the whole month is billed at Rs 36.46/unit instead, roughly Rs 13,592.
SEPCO put me in the Unprotected category — how would that change to Protected?
By your consumption pattern over time, not by request — average 200 units or less across 6 months and you'd qualify for Protected, or 100 units or less across 12 months for Lifeline. SEPCO recalculates this automatically and updates the category printed on your bill, so always enter whatever's shown there.
Does the FPA line on a SEPCO bill ever help lower the total?
It can. FPA compares the fuel cost the tariff assumed against what generation actually cost that month, billed with roughly a two-month delay. A month where real fuel costs came in under the assumption produces a negative FPA, which subtracts from your bill rather than adding to it — check your latest bill for the current sign and size.
My SEPCO meter barely moved this month — why wasn't the bill close to zero?
Because the fixed/customer charge is billed on your sanctioned load in kW, not on units consumed, so it applies even at near-zero usage (a flat per-consumer fee covers the smallest categories instead). Only Lifeline consumers skip this charge, and they pay a minimum monthly amount in exchange.
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 SEPCO. FPA/QTA/GST/Electricity Duty change monthly or quarterly — verify against your own bill before making financial decisions.
