How Much Is a 100 Unit PESCO Bill

Understanding the 100-Unit PESCO Tariff Structure

A 100 unit bill sits entirely within the first consumption block of PESCO’s domestic tariff. That sounds simple, but the rate applied to those 100 units is not the same for every household. The decisive factor is your consumer category: protected or unprotected.

Protected status is not decided month by month in isolation. Under the current framework, a non-TOU residential consumer generally qualifies as protected when monthly consumption stays at or below 200 units consistently over the previous six months. Once that pattern is broken, the account can be treated as unprotected, and the higher rate structure applies. For a 100 unit bill, this distinction matters because the same 100 units are priced at different per-unit rates depending on which category PESCO has recorded for your connection.

For protected consumers, the 1–100 unit block carries a lower subsidised rate. The 101–200 block is priced higher, but still below unprotected levels. For unprotected consumers, even the first 100 units are billed at a noticeably higher rate. This is why two neighbours with identical 100 unit consumption can receive very different bills. The Peshawar electric unit price you see on your bill is the outcome of this category split, not a universal rate for the city.

The slab structure is progressive in the sense that different blocks have different rates, but the protected category is the main reason a 100 unit bill stays relatively low. If you want the full slab-by-slab rate table for PESCO, the PESCO tariff slab rates guide covers the current domestic blocks in more detail.

It also helps to separate the energy charge from everything else on the bill. The 100 units are multiplied by the applicable per-unit rate, but that energy subtotal is only one part of the final payable amount. Fixed charges, taxes, and monthly adjustments are added afterward, and they can make a noticeable difference even on a low-consumption bill.

Step-by-Step Calculation for a 100-Unit Bill

To estimate a 100 unit PESCO bill, work through the bill in the same order PESCO does: energy charge first, then fixed charges, then taxes and adjustments.

Step 1: Identify your consumer category. Check whether your account is protected or unprotected. If your last six months have consistently stayed at or below 200 units, you are likely in the protected category. If you crossed that threshold recently, the unprotected rate may apply.

Step 2: Apply the per-unit rate to 100 units. Multiply 100 by the rate for the 1–100 block that applies to your category. Because protected and unprotected rates differ, this single step is where most of the variation between two 100 unit bills comes from. This is also where the Peshawar electric unit price becomes concrete: it is the block rate your category receives, not a headline average.

Step 3: Add the fixed charge. PESCO’s domestic tariff includes a fixed monthly charge that is not based on units consumed. The exact amount depends on your sanctioned load and tariff schedule. Even a household using only 100 units pays this charge if it applies to the connection.

Step 4: Add GST and electricity duty. General sales tax and electricity duty are applied to the bill according to the prevailing rates. These are percentage-based charges, so they scale with the energy charge and fixed charge rather than with unit count alone.

Step 5: Add the PTV licence fee. A flat PTV fee is typically included on domestic bills. It does not change with consumption, so on a 100 unit bill it forms a relatively larger share of the total than it would on a high-usage bill.

Step 6: Check for FPA or QTA. Fuel Price Adjustment and Quarterly Tariff Adjustment are monthly or quarterly pass-through amounts. They can be positive or negative and are not fixed by the slab rate. A month with a negative FPA can reduce the bill, while a positive FPA adds to it. Because these adjustments apply per unit, even a 100 unit bill feels them in proportion to consumption.

A simple way to read the result is this: the 100 unit energy charge is the core, the fixed charge is a flat addition, the percentage taxes apply on top, and the FPA/QTA line is the variable that changes from month to month. If your bill looks higher or lower than an online estimate, the adjustment line is usually the reason.

For a worked comparison, third-party tariff trackers have estimated 100 unit domestic bills at roughly Rs 1,466 for protected consumers and Rs 3,104 for unprotected consumers under a 2026 schedule, before fixed capacity charges and with FPA/QTA assumed at zero. Treat those figures as illustrative rather than as a PESCO-issued amount, because your actual bill will reflect your own fixed charge, taxes, and the adjustment line for that billing month.

If you want to verify the inputs PESCO used for your own connection, checking your duplicate bill online is the most direct way to see the recorded units, slab, and charges side by side. The PESCO bill SMS and email registration guide explains how to set up alerts so you see the bill as soon as it is generated.

Peshawar Electric Unit Price: What the First 100 Units Actually Cost

The phrase Peshawar electric unit price is often searched as if there were one rate for the whole city. In practice, the price of a unit in Peshawar depends on the same national uniform tariff that applies to other Ex-WAPDA distribution companies, plus the consumer category and the month’s adjustments. For a 100 unit household, the relevant price is the 1–100 block rate for your category, not the average rate across all consumption levels.

A useful comparison is between the protected and unprotected first-block rates. The protected first block is deliberately subsidised to keep low-usage households affordable. The unprotected first block is higher because the household has been placed in the standard category. The gap between these two rates is the main reason a 100 unit bill can look very different from one house to the next in Peshawar, Mardan, or any other PESCO area.

Bill component	What it depends on	How it affects a 100-unit bill
First-block energy rate	Protected vs unprotected category	Sets the core Peshawar electric unit price for the 100 units
Fixed charge	Sanctioned load and tariff schedule	Adds a flat amount even when consumption is low
FPA / QTA	Monthly NEPRA notification and quarter	Adds or subtracts a per-unit amount across all 100 units
GST and electricity duty	Percentage of the bill base	Scales with the energy and fixed charges
PTV fee	Flat domestic charge	Forms a larger share of a small bill

This table also explains why a simple “units × one rate” estimate misses the mark. The Peshawar electric unit price for the first 100 units is only the starting point; the final amount is the sum of that energy charge plus the fixed and variable additions shown above.

Taxes, Surcharges, and Adjustments on Low-Tier Bills

A 100 unit bill may be small in energy terms, but it is not tax-free. Several charges apply regardless of how few units you use, and understanding them helps you check whether a bill is accurate.

GST and electricity duty are the main percentage-based additions. GST applies at the prevailing standard rate, and electricity duty is levied as a percentage of the bill. Because both are calculated on the energy charge plus applicable fixed charges, they rise and fall with the tariff category. A protected 100 unit bill pays these charges on a lower base than an unprotected bill.

The PTV licence fee is a flat charge on domestic bills. It does not depend on consumption, so it appears in full even on a 100 unit bill. This is one reason a very low-usage bill can feel proportionally heavier than the unit count suggests.

Fixed charges are not a tax, but they behave like one on a low-consumption bill. If your connection carries a fixed monthly charge based on sanctioned load, that amount is due whether you use 100 units or fewer. Households with a small sanctioned load pay less; households with a larger sanctioned load pay more.

Fuel Price Adjustment and Quarterly Tariff Adjustment are the most variable lines. FPA reflects changes in fuel costs for power generation and is passed through monthly. QTA reflects quarterly adjustments in capacity, transmission, and variable O&M costs. On a 100 unit bill, a positive adjustment of a few rupees per unit can add a meaningful amount because it applies across the units consumed. A negative adjustment works in the opposite direction.

One point that often confuses low-usage households is the interaction between protected status and adjustments. Even if your slab rate is protected, the FPA and QTA lines can still appear. They are not automatically waived because you used only 100 units. The protection applies to the tariff slab, not to every pass-through charge.

If you suspect a charge is incorrect, the first step is to compare the units on your bill with your meter reading and check whether your protected status is recorded correctly. PESCO circle offices and complaint centres handle billing disputes, and the PESCO helpline and complaint centre guide lists the contact points for each circle. For a bill that looks unusually high, ask specifically whether the FPA/QTA line or a change in protected status is responsible before assuming the slab rate itself is wrong.

Protected vs. Unprotected: Why 100 Units Matters

The 100-unit mark sits at the very bottom of the protected-consumer ladder, and that position is both a shield and a trap. As long as a household stays inside the protected category, the first block of units is billed at the subsidised rate. Cross the protected threshold—or lose the status for other reasons—and the same 100 units can cost roughly twice as much once the higher slab and full surcharges apply.

The protected category is not a permanent label. Eligibility is generally tied to consumption history, and a single month above the limit can affect the category going forward. Regaining protected status usually requires a sustained period of low usage, commonly described as six consecutive months of staying within the limit. That waiting period is the real financial sting: even a brief overshoot can push several future bills into the unprotected column.

For a 100-unit consumer, the practical lesson is that staying below the line matters more than the exact number of units. A bill for 95 units and a bill for 100 units are usually close in cost. A bill for 100 units and a bill for 201 units are not. The jump at the boundary reflects a change in consumer category, not just a few extra kilowatt-hours.

Two edge cases deserve attention. First, multiple meters at one premises do not automatically preserve protected status for each connection; billing systems evaluate each connection against the applicable rules. Second, a high sanctioned load or a registered air conditioner can affect category treatment regardless of how few units are consumed. If your usage is genuinely low but your bill still looks unprotected, compare the tariff line on your bill against the protected slab rather than assuming the units alone decide the outcome.

This is also why the Peshawar electric unit price cannot be quoted as a single figure without asking “for which category?” A protected household and an unprotected household in the same street can see different first-block rates on their bills, and both can be correct under the applicable tariff.

How a 100-Unit Bill Compares With 200 and 300 Units

A 100 unit bill is a useful baseline, but many households want to know how the amount changes when consumption rises. The comparison below shows the principle without pretending to give an exact PESCO figure for every month, because FPA, QTA, fixed charges, and taxes vary by connection and billing period.

Consumption	Tariff position	What changes in the bill
100 units	Entirely in the first block	Lowest energy charge; fixed charge and taxes still apply
200 units	First and second blocks	Second-block units cost more; protected status may still apply if history is within limit
201 units	Unprotected category triggered for many households	All units can be re-priced at unprotected rates, not just the extra unit
300 units	Deeper into higher blocks	Higher per-unit rates apply to more units; FPA/QTA applies across all units

The key insight is that the 100-unit bill is relatively stable because it stays within one block and is often the easiest to keep protected. The 200-unit bill is still manageable for protected households, but the 201-unit boundary is where category risk becomes visible. A 300-unit bill involves more higher-block units and is less likely to remain protected unless consumption history supports it.

For a household trying to budget, the 100-unit bill is the low-usage anchor. The moment consumption approaches 200 units, the question shifts from “what is my per-unit price?” to “will I stay protected next month?” That is a more important question than the exact Peshawar electric unit price for a single block.

Tips to Keep a 100-Unit Bill Accurate and Manageable

Keeping a 100-unit bill predictable is mostly about avoiding surprises in the adjustment and category lines, not just reducing consumption.

Check your protected status on the bill. If you believe you qualify as protected but the bill shows unprotected rates, ask PESCO to verify the category. The unit count alone does not tell you which rate was applied.

Compare the FPA and QTA lines month to month. A positive FPA can make a 100-unit bill look higher than last month even when your consumption is unchanged. A negative FPA can make it look lower. Neither is a billing error by itself.

Read the fixed charge separately. A high sanctioned load can keep the fixed portion of the bill high even when you use very few units. If you have reduced your load requirements, ask whether the sanctioned load can be revised through the proper PESCO process.

Use the duplicate bill for verification. Online estimates are useful for budgeting, but the duplicate bill shows the exact tariff lines, units, and adjustments for your connection. If the estimate and the bill disagree, trust the bill and look for the line that explains the gap.

Watch the 200-unit boundary. If your usage is creeping toward 200 units, the financial risk is not just the extra units. It is the possibility of losing protected status for future months. Staying comfortably below the threshold is often more valuable than shaving a few rupees off the current bill.
