What every line on your electricity bill means

Who sets, calculates and prints your bill

Four organisations touch the piece of paper that arrives at your door, and knowing which one is responsible for a given line saves a wasted trip to the wrong office.

The practical consequence: a dispute about how many units you were billed for is a matter for your DISCO, because it took the reading. A complaint about what a unit costs is not — that rate was notified by NEPRA and applies identically to every consumer in your category across the country.

Where each field sits on the page

Because PITC generates bills for all eleven companies from one system, the layout is consistent. Whatever your company, the bill reads top to bottom in the same six bands, and the explanations further down this page follow the same order.

The top band identifies the connection and rarely changes month to month. The second carries the reference number, fourteen digits on a standard domestic connection, which is the key to everything else: it is what a duplicate-bill lookup needs, what a payment app needs, and what an office will ask for before discussing anything.

Bands three to five are where the money is decided, and where this page spends its time. The final band is the one most people read first and understand least, because it contains two different figures rather than one.

The two numbers everything else follows from

Strip away the taxes and adjustments and a bill is determined by exactly two inputs. Get these two right and the rest of the bill is arithmetic.

Units consumed

The difference between this month's meter reading and last month's, in kilowatt-hours. Both readings are printed on the bill, along with the dates they were taken. Check this before anything else, for two reasons. First, the reading period is often not a calendar month. A bill covering 34 days will look higher than one covering 28 for reasons that have nothing to do with your usage. Second, an estimated reading, which some bills mark explicitly, will be corrected on a later bill and can produce an artificial spike followed by an artificial dip.

Tariff category

The code printed near the top of the bill, A-1a, A-2, B-1 and so on, that says what kind of connection this is. It determines which rate schedule applies, what the fixed charge is, whether time of day matters, and whether protected status is even available. A domestic meter that has been recorded as commercial will produce a bill that is correct arithmetic on the wrong schedule, and it will keep doing so every month until someone corrects the record.

Reading your tariff code

Tariff codes look cryptic but decompose predictably: a letter for the broad class, a number for the size or sub-type, sometimes a letter for the phase, and sometimes a trailing T for a Time-of-Use meter.

Lifeline, protected and unprotected consumers

Within the residential category there are three sub-classes, and which one you fall into can change your bill more than any other single factor. None of them are something you apply for. They are computed from your own meter history, every month, automatically.

The six-month rule, and why one hot month costs half a year

Protected status is not a rolling average and it is not judged on the current month. It asks a stricter question: was every one of the last six months at or below 200 units? A single month above the line answers no, and keeps answering no until that month has passed out of the six-month window.

This is why a household can find itself paying unprotected rates in November for a July air conditioner. It also means the recovery is worth planning for: if you are close to the threshold, the difference between 198 and 205 units in one month is not the cost of seven units, it is the cost of six months on a higher schedule.

How slabs are actually applied

This is the most misunderstood mechanism on the bill, and the one responsible for most of the shocking jumps. The intuition almost everyone brings to it is that slabs work like income tax brackets, where only the units above a threshold are charged at the higher rate. That is not how domestic electricity billing works for most consumers in Pakistan.

Slab benefit, and who gets it

“Slab benefit” is the term for being charged progressively, some units at a lower band's rate and only the remainder at the higher one. Under the notified schedule, it is a concession granted to protected residential consumers rather than a general rule. For a domestic consumer who is not protected, the whole month's consumption is charged at the rate of the band the total reaches.

The consequence is a cliff rather than a slope. Consider two months at an unprotected household, and assume for illustration that the band up to 300 units is charged at one rate and the band above it at a higher one:

Two things follow from this. First, when a bill roughly doubles on a modest rise in usage, the band boundary is the first thing to check, not a meter fault. Second, the most valuable thing a household near a boundary can do is know where the boundary is and watch the meter as the month closes.

Fixed charges and meter rent

Fixed charges pay for the connection rather than for consumption: the share of the distribution network, transformer capacity and metering that is reserved for your premises whether you draw power through it or not. They appear on the bill even in a month when the property was empty.

For most non-domestic categories the charge is levied per kilowatt of sanctioned load, the capacity your connection is approved for, printed on the bill — rather than per kilowatt actually used. Industrial categories carry substantially larger fixed charges than domestic ones, which is part of why a miscategorised connection is expensive.

For domestic connections the charge differs between single-phase and three-phase supply, and the structure has been extended in recent tariff decisions to cover consumption bands that previously carried no fixed charge at all. Where the charge is tied to a consumption band, it steps up as the band does, so crossing a boundary can raise two separate lines on the bill at once.

Fuel Price Adjustment: the line nobody expects

NEPRA sets the base tariff using an assumed reference cost for the fuel that generators will burn. Fuel prices move constantly, and reopening the base tariff every time would be unworkable. So the difference between assumed and actual fuel cost is recovered, or refunded, through a separate monthly line instead.

1. 1

   Fuel is burnt

   Generators run through the month on whatever mix of gas, coal, furnace oil, hydro, nuclear and renewables the system dispatches. The actual cost of that mix differs from the reference cost built into the tariff.

2. 2

   CPPA-G files, NEPRA hears

   Once the month closes, CPPA-G files the actual generation costs. NEPRA holds a public hearing, scrutinises the claim, and notifies an adjustment figure in rupees per unit.

3. 3

   It reaches your bill

   The notified figure is multiplied by the units youconsumed in the current billing month and printed as a separate line. So the rate comes from an earlier month, but the units it is applied to are this month's.

Two things about this line surprise people. The first is that it can be negative: when actual fuel costs come in below the reference, the adjustment is a credit and reduces the bill. The second is that it is uniform — the same rupees-per-unit figure applies to every consumer in the category nationwide, so it is never evidence of a fault with your particular meter.

The dedicated guide goes further into how the figure is determined and why protected consumers are treated differently: Fuel Price Adjustment explained.

Quarterly adjustment and surcharges

Fuel is not the only thing that turns out differently from what the tariff assumed. The quarterly adjustment settles the rest.

Quarterly Tariff Adjustment

Where FPA corrects for fuel, the quarterly adjustment, printed variously as QTR ADJ or DMC, trues up the other assumptions: capacity payments owed to generators regardless of how much they generated, transmission charges, and use-of-system costs. NEPRA determines it for a quarter and it is then applied across the following months, so it can appear on several consecutive bills at the same rate and then change abruptly.

Surcharges

Separate from both adjustments, government-mandated surcharges are levied to service sector debt and fund reform. They are policy instruments rather than a cost of supplying your particular connection, they apply across consumer categories, and no distribution company has authority to reduce or waive one.

The tax stack

Several separate taxes are collected through the electricity bill by different levels of government. Your distribution company collects them; it does not set them and cannot waive them.

Lines that are not electricity at all

Some of what you pay through the electricity bill has nothing to do with electricity. The bill is simply an efficient collection channel, and these items ride along on it.

PTV licence fee

A flat monthly amount collected on behalf of Pakistan Television Corporation under a government directive. It does not vary with consumption, and it is charged whether or not the household owns a television. Because your distribution company is collecting it for another body, it has no authority to remove it. A request has to go to the relevant government department instead.

Arrears

Amounts from earlier bills that the company has not recorded as paid, carried forward onto the current one. Check arrears rather than accepting them: compare the figure against the “payable after due date” amount on your previous bill. If you have a receipt for a payment that is nonetheless showing as arrears, that is a dispute to raise with proof, not a balance to settle twice.

Instalments and deferred amounts

Where a large corrected bill or an agreed settlement has been spread across months, the monthly portion appears as its own line. These have an end date, so keep track of how many instalments remain. A bill that stays high after the final one has been paid is a billing error worth raising immediately.

The two payable figures, and what happens after

The bottom of the bill carries two amounts, not one, and the difference between them is the most avoidable cost on the page.

Scroll the table sideways to see every column.

The trap is paying the lower figure a day or two late. The payment is accepted, but it does not clear the amount now owed, and the shortfall reappears as arrears on the next bill — often small enough to be missed, and compounding quietly across months. If you are paying after the due date, pay the higher figure.

Which payment channels credit your account immediately and which take a day or more is a practical question in its own right, and it is covered on ways to pay an electricity bill.

A whole bill, line by line

Putting the order together. The figures below are illustrative placeholders rather than current rates, what matters is the sequence, because each step operates on the result of the one before it.

This is also the order to check a bill in. If the units are right, work down: the band, then the fixed charge, then each adjustment, then the taxes. The first line that does not make sense is usually the whole explanation.

Why a bill suddenly jumps

Most large increases have one of a small number of causes, and they are distinguishable from each other by looking at different parts of the bill. Working through them in this order will usually identify the reason within a few minutes.

1. 1

   The reading period was longer

   Compare the two reading dates against the previous bill's. A 34-day period against a 27-day one is a 26% larger bill from an identical daily habit. Check this before anything else, because it explains a surprising share of “unexplained” increases.

2. 2

   The month crossed a band boundary

   Check the units against the boundaries. Because the whole month is re-priced rather than only the excess, this produces a jump out of all proportion to the extra units, and it is the most common single cause.

3. 3

   Protected status was lost

   Look at the tariff marker. If a month in the last six went above 200 units, this bill is on unprotected rates, and it will stay there for the remainder of the six-month window even as consumption falls back.

4. 4

   The previous reading was estimated

   An estimated month that under-recorded consumption is corrected on the following bill, which then carries both months' real usage. The tell is an unusually low bill immediately before the high one.

5. 5

   The fuel or quarterly adjustment moved

   Compare the adjustment lines against the previous bill. These are uniform across all consumers, so a rise here is nothing to do with your meter — and it will be visible on your neighbours' bills too.

6. 6

   Arrears were added

   A partially paid or missed earlier bill appears here. Check it against the previous bill's after-due-date figure rather than assuming it is correct.

7. 7

   The tariff category changed

   Uncommon, but it happens after a change of connection details or an inspection. A domestic connection re-recorded as commercial raises both the per-unit rate and the fixed charge simultaneously.

8. 8

   Something really is drawing more power

   Only worth investigating once the seven above are ruled out. A failing refrigerator or air-conditioner compressor, a submerged or leaking water pump, or an unauthorised connection downstream of your meter will all show as a real, sustained rise in units rather than a one-month spike.

If a component looks wrong

Not everything on a bill can be disputed, and knowing which is which saves considerable time. Rates, adjustments, surcharges and taxes are notified centrally and apply identically to everyone in your category, arguing about them at a distribution company office cannot succeed, because nobody there has the authority to change them.

What is disputable is anything specific to your connection:

• The meter reading, and whether it was actually taken rather than estimated
• The number of units billed, as arithmetic on those readings
• The tariff category and sanctioned load recorded against the connection
• Protected status, if your consumption history supports it
• Arrears, particularly where you hold a receipt
• A detariffed, defective or stopped meter

The route starts with your Subdivision Officer, escalates within the distribution company, and ends, if it must, at NEPRA, which has jurisdiction over consumer complaints against distribution companies. The full escalation path, what to bring, and realistic expectations at each stage are set out on complaints and helplines.
