Every rupee-per-unit on your electricity bill traces back to one regulator: NEPRA, the National Electric Power Regulatory Authority. It approves the tariff that all eleven WAPDA distribution companies charge, holds public hearings before any change, and extends the quarterly adjustments to K-Electric consumers as well.
Yet almost nobody can explain where the numbers on their bill come from — why the rate jumped in July, what that "FCA" line means, or why a relief suddenly appeared three months later. This explainer closes that gap: who sets the tariff, how often it moves, and exactly how each movement lands on your bill.
If you only want the math, our electricity bill calculator applies the current schedule to your units in one tap.
Who decides electricity rates in Pakistan — and how often they change
NEPRA approves one uniform base tariff for the eleven ex-WAPDA DISCOs (LESCO, FESCO, GEPCO, IESCO, MEPCO, PESCO, HESCO, SEPCO, QESCO, TESCO and HAZECO). The base tariff is revised once a year, around July. On top of it, two mechanisms move your bill between revisions: the Fuel Charges Adjustment (FCA), applied monthly, and the Quarterly Tariff Adjustment (QTA), applied every three months — sometimes as a charge, sometimes as relief.
That is why two neighbours with identical units can pay different amounts in different months: the base slab rates are the same, but the adjustment lines differ.
Current residential and commercial slab rates
These are the energy-charge rates the current schedule uses — the same ones our calculator applies. Slabs work stepwise: your units fill the cheapest band first, then the next.
Protected consumers
Households that stay under 200 units for six consecutive months keep protected status — and by far the cheapest rates in the country.
| Units | Rate per unit | Note |
|---|---|---|
| 1–50 (lifeline) | Rs 3.95 | Protected households only |
| 51–100 | Rs 7.74 | Protected households only |
| 101–200 | Rs 10.06 | Last protected slab |
Unprotected consumers
One month above 200 units and the account drops out of protected status — the jump from Rs 10.06 to Rs 22.44 on the very first band is the most expensive lesson on any Pakistani bill.
| Units | Rate per unit |
|---|---|
| 1–100 | Rs 22.44 |
| 101–200 | Rs 28.91 |
| 201–300 | Rs 33.10 |
| 301–400 | Rs 36.46 |
| 401–500 | Rs 38.95 |
| 501–600 | Rs 40.22 |
| 601–700 | Rs 41.62 |
| Above 700 | Rs 47.20 |
Commercial connections
| Units | Rate per unit |
|---|---|
| 1–100 | Rs 33.50 |
| 101–300 | Rs 38.10 |
| Above 300 | Rs 43.40 |

How NEPRA actually sets a tariff
The annual cycle is public and follows the same script every year:
- DISCOs file petitions. Each company submits its cost data — power purchase prices, losses, operation costs — and asks for the revenue it says it needs.
- NEPRA holds public hearings. Consumers, analysts and companies can appear and object. The hearings are open, and the objections often trim the ask.
- The Authority issues its determination. NEPRA approves a consumer-end tariff with reasons on record, published on nepra.org.pk.
- The federal government notifies it. The notified tariff becomes the schedule every DISCO bills against — usually aligned to the July fiscal year.
In the 2026 cycle the Authority determined the calendar-2026 consumer-end tariff on 7 January, recommended a uniform structure on 12 January, and the government notified it on 13 January — one national schedule for all DISCOs.
FCA: the fuel line that moves every month
The Fuel Charges Adjustment reconciles what electricity actually cost to generate against what the tariff assumed. Fuel prices move monthly, so the FCA moves monthly too — it appears on the bill as a per-unit amount, positive or negative, and multiplies across every unit you consumed.
On a 400-unit bill, a Rs 2 FCA line is Rs 800. That single line is why "same units, different total" happens more often than any slab change. Read the FCA line before blaming the meter.
QTA: the quarterly adjustment, with 2026 examples
The Quarterly Tariff Adjustment reconciles the bigger cost items — capacity payments, T&D losses, use-of-system charges — once a quarter. NEPRA announces the number; recovery (or relief) lands on bills over the following three months. Two real 2026 determinations show both directions:
Q2 FY2025-26: a positive adjustment
NEPRA notified +Rs 0.3504 per unit, recovering about Rs 8.674 billion across the bills of March to May 2026 — uniform for all categories except lifeline, prepaid and incremental-package consumers, and applied to K-Electric as well.
January–March 2026 quarter: a negative one
The Authority approved a negative adjustment of Rs 1.9857 per unit — roughly Rs 67.17 billion of relief — passed on through the bills of June, July and August 2026, again including K-Electric consumers and excluding the same three groups. Net-metering exports in that quarter were accounted at Rs 25.32 per unit.
The lesson: the QTA is not a fine or a favour. It is arithmetic, decided in public, three months after the fact.
What sits on top of the energy charge
The slab math is only the middle of the bill. The full stack, in the order bills usually print it:
- Energy charges — units × slab rates
- FCA / FPA line — the monthly fuel reconciliation
- QTA line — the quarterly reconciliation, when applicable
- Electricity duty and GST — the tax block, currently 18% GST
- TV licence fee — a fixed Rs 35 on domestic bills
- Late payment surcharge — only if the due date passed
A quick way to sanity-check any bill: energy + FCA + taxes should account for nearly everything. If a line cannot be named, ask the DISCO office for it in writing — or start from our calculator and compare the totals.
Protected vs unprotected: how the status is won and lost
Protected status belongs to the account, not the month. A household that consumes 200 units or less for six consecutive months is billed at the protected schedule — as low as Rs 3.95 per lifeline unit. Cross 200 units in any month and the account falls to unprotected rates from the next assessment, where the first band alone costs Rs 22.44.
The status line is printed on the bill itself ("Protected" / "Unprotected" near the tariff code). If it changed without an obvious heavy month, check the twelve-month history on the online bill — one AC summer or one wedding month is usually the culprit. Status recovers the same way it was lost: six clean months.
Where K-Electric differs
K-Electric files its own tariff petitions, so its base schedule has its own history and its own tariff names. But the adjustment mechanisms follow NEPRA's determinations: the same quarterly adjustments — including the Rs 1.9857 relief of mid-2026 — were extended to KE consumers for the same months, with the same exemptions for lifeline, prepaid and incremental-package billing.
Practically: a Karachi bill can differ from a Lahore bill at the base-rate level while moving in lockstep on the quarterly lines. The K-Electric bill pillar covers the KE bill itself.
How to verify any rate claim in two minutes
Rate rumours spread faster than notifications. Before trusting a forwarded screenshot:
- Open your latest bill. The tariff code and per-unit lines printed on it beat any WhatsApp forward.
- Check nepra.org.pk. Determinations and notifications are published there with dates and reference numbers.
- Run the calculator. Enter your units and category in our bill calculator — if the result is far from the paper bill, the difference is usually an adjustment line, not a rate change.
Frequently asked questions
Who decides electricity rates in Pakistan?
NEPRA — the National Electric Power Regulatory Authority — approves one uniform tariff for all eleven ex-WAPDA DISCOs after public hearings, and the federal government notifies it. K-Electric files its own petitions but follows the same quarterly adjustment determinations.
How often do electricity rates change?
The base tariff is revised once a year, around July. On top of it, the Fuel Charges Adjustment moves monthly and the Quarterly Tariff Adjustment moves every three months — either direction.
What is the QTA on my bill?
The Quarterly Tariff Adjustment reconciles capacity payments, losses and system charges every quarter. In 2026 it added Rs 0.3504 per unit on March–May bills and cut Rs 1.9857 per unit on June–August bills.
Is the LESCO tariff different from FESCO or GEPCO?
No. The eleven DISCOs bill against one uniform NEPRA-approved schedule — only surcharges, losses and adjustment timing can make two bills look different.
What is a protected consumer?
A household under 200 units for six consecutive months, billed at the cheapest schedule — from Rs 3.95 per lifeline unit. Crossing 200 units in any month drops the account to unprotected rates.
Does K-Electric follow the same tariff?
KE's base schedule comes from its own petitions, but NEPRA's quarterly adjustments — including the mid-2026 relief — apply to KE consumers on the same months, with lifeline, prepaid and incremental-package consumers exempt.
Where can I see the official current rates?
On your own bill's tariff lines first, then in NEPRA's published determinations on nepra.org.pk. Our calculator applies the same current schedule if you want an instant estimate.
