How Electricity Tariff Slabs Work in Pakistan

✓ Quick Answer Electricity in Pakistan is billed on a slab system — the more units you consume in a month, the higher the per-unit rate you pay, not just on the extra units but often on your entire consumption. Rates are set by NEPRA (National Electric Power Regulatory Authority) and applied uniformly by all DISCOs (LESCO, MEPCO, PESCO, IESCO, FESCO, GEPCO, HESCO, QESCO, TESCO, SEPCO). On top of the base slab rate, your bill also includes Fuel Price Adjustment (FPA), quarterly tariff adjustments, GST, and other charges — which is why two households using similar units can still see very different totals.

Who Sets Electricity Rates in Pakistan?

A common misconception is that LESCO, MEPCO, or your local DISCO decides how much you pay per unit. They don’t. NEPRA sets a uniform national tariff for all distribution companies, and DISCOs simply apply that rate to their consumers based on category and consumption. This is why a household in Lahore (LESCO) and a household in Multan (MEPCO) using the same number of units pay essentially the same base rate — the difference in your final bill usually comes from local taxes, surcharges, or connection type, not from a different per-unit price.

How the Slab System Works

Instead of one flat rate, domestic electricity tariffs are divided into consumption brackets, or “slabs.” As your monthly usage moves into a higher slab, the rate for units in that slab increases. Broadly, domestic consumers fall into three groups:

• Lifeline consumers — very low usage, roughly up to 50 units a month, charged the lowest rate to protect low-income households.
• Protected consumers — monthly consumption up to 200 units, charged at a subsidized rate lower than the general public rate.
• Non-protected (general) consumers — anyone using more than 200 units in a month, charged at higher, unsubsidized rates that increase further as consumption rises (typically up to 700+ units).

Important: Crossing 200 units in even one month can move you from “protected” to “non-protected” status for that entire billing cycle — not just for the units above 200. This is one of the most common reasons people are surprised by a sudden jump in their bill, and it’s worth watching closely if your usage is close to that threshold.

What Else Gets Added to the Base Rate

The per-unit slab rate is only the starting point. Your final bill typically includes:

• Fuel Price Adjustment (FPA): A monthly adjustment reflecting the actual cost of fuel used to generate electricity that month. It can add or subtract a few rupees per unit and changes almost every billing cycle.
• Quarterly Tariff Adjustment (QTA): A periodic adjustment NEPRA applies to account for cost differences between what was estimated and what DISCOs actually spent.
• GST: General Sales Tax applied to the electricity charges.
• Income Tax: Withheld on bills above a certain threshold, at a different rate depending on whether you’re a filer or non-filer.
• TV Fee: A small fixed monthly charge collected on behalf of PTV.
• Fixed/meter rent charges: A flat monthly charge depending on your connection type (single-phase or three-phase).

This is exactly why the “per-unit rate” you see quoted online rarely matches your final bill amount — the base tariff is just one line among several.

A Simplified Example

Say a non-protected household uses 250 units in a month, split roughly like this:

• First 100 units at the lower general rate
• Next 100 units at the next slab’s rate
• Remaining 50 units at a higher slab rate

Each block is charged at its own rate, then FPA, GST, income tax, and fixed charges are added on top. The result is that your effective per-unit cost — total bill divided by total units — is almost always higher than the lowest slab rate advertised, especially once you cross into non-protected territory.

Because FPA and quarterly adjustments change regularly, the exact rupee figures for each slab shift over time. Rather than quoting numbers that may already be outdated by the time you read this, the most reliable way to see your current applicable rate is to check the tariff notice printed on your latest bill, or your DISCO’s official tariff page.

How to Check Your Own Bill Against These Slabs

1. Find your monthly units consumed — printed on your bill or visible from your meter reading history.
2. Check whether your total crosses 100, 200, or 300 units — these are the common slab boundaries.
3. Look at the breakdown section of your bill for FPA, QTA, and tax lines, rather than assuming the whole bill is just “units × rate.”
4. If your bill shows a rate that doesn’t match what you expected, it’s usually the FPA or quarterly adjustment, not an error — but it’s still worth confirming with your DISCO if the jump seems unusually large.

Frequently Asked Questions

Does every DISCO charge a different rate? No. NEPRA sets one uniform tariff structure nationally. Differences between DISCOs in your final bill usually come from local taxes or surcharges, not the base slab rate itself.

Why did my bill jump even though my usage barely changed? This is most often the FPA or quarterly adjustment changing month to month, or your consumption crossing a slab boundary (like moving from 190 to 210 units) that shifted your entire bill into a higher category.

Is the slab rate applied only to the extra units, or the whole bill? For protected vs. non-protected status, crossing 200 units can reclassify your entire month’s consumption at the higher rate — not just the units above 200. Within the non-protected slabs themselves, each block of units is generally charged at its own slab rate.

Where can I see the exact current rates for my usage? Your monthly bill includes the applicable tariff notification. You can also check your DISCO’s official tariff page or NEPRA’s public notifications for the latest approved rates.
