📊 Understanding Electricity Tariffs in Pakistan: Complete 2026 Guide
Electricity tariffs in Pakistan can be confusing with multiple slabs, adjustments, surcharges, and taxes. This comprehensive guide explains how the tariff system works, what determines your per-unit rate, and why your bill might vary even with similar consumption. Understanding these concepts will help you better manage your electricity costs and verify your bills.
The Power Sector Structure in Pakistan
Before understanding tariffs, it's helpful to know how the electricity sector is organized:
Key Organizations
- NEPRA (National Electric Power Regulatory Authority): Sets tariffs, approves adjustments, regulates the sector
- CPPA-G (Central Power Purchasing Agency - Guaranteed): Purchases electricity from generators on behalf of DISCOs
- NTDC (National Transmission & Despatch Company): Manages the national transmission grid
- DISCOs (Distribution Companies): Distribute electricity to consumers (MEPCO, LESCO, IESCO, etc.)
- Generation Companies: Produce electricity (WAPDA hydro, thermal IPPs, nuclear, renewable)
How Tariffs are Set
NEPRA determines tariffs through a detailed process:
- DISCOs submit tariff petitions based on costs
- NEPRA conducts public hearings
- NEPRA issues determination after analysis
- Government notifies the tariff (may include subsidies)
- DISCOs implement the notified tariff
Consumer Categories
Different types of consumers are charged different rates based on their connection type:
| Tariff Code | Consumer Type | Examples |
|---|---|---|
| A-1(a) | Domestic Protected | Homes with ≤200 units avg |
| A-1(b) | Domestic Non-Protected | Homes with >200 units avg |
| A-2 | Commercial | Shops, offices, clinics |
| A-3 | General Services | Government buildings, street lights |
| B-1 | Industrial (Small) | Up to 25 kW load |
| B-2 | Industrial (Medium) | 25-500 kW load |
| B-3 | Industrial (Large) | Above 500 kW load |
| B-4 | Industrial ToU | Time-of-Use metered industries |
| D | Agricultural | Tube wells, farms |
The Progressive Slab System
Pakistan uses a progressive slab-based tariff for residential consumers. The more electricity you consume, the higher the rate per unit:
| Consumption Slab | Category | 2026 Rate (PKR/unit) |
|---|---|---|
| 0-50 Units | Lifeline | 3.95 |
| 1-100 Units (Protected) | Protected | 7.74 |
| 101-200 Units (Protected) | Protected | 10.06 |
| 1-100 Units (Non-Protected) | Non-Protected | 16.48 |
| 101-200 Units | Non-Protected | 22.95 |
| 201-300 Units | Non-Protected | 27.14 |
| 301-400 Units | Non-Protected | 32.03 |
| 401-500 Units | Non-Protected | 35.24 |
| 501-600 Units | Non-Protected | 36.66 |
| 601-700 Units | Non-Protected | 37.80 |
| Above 700 Units | Non-Protected | 42.72 |
⚠️ Critical: The Slab Threshold Effect
When you cross the 200-unit threshold, ALL your units are charged at Non-Protected rates - not just the excess. Using 201 units can cost nearly double what 199 units costs. This is the single most important thing to understand about tariffs.

Components of Your Final Rate
Your per-unit cost is not just the base tariff. Several additions and adjustments determine your final rate:
1. Base Tariff (Variable Charges)
The fundamental rate per unit as determined by NEPRA. This varies by slab and consumer category. It covers:
- Cost of electricity generation
- Transmission costs (NTDC charges)
- Distribution costs (DISCO operating expenses)
- Allowed profit margin for companies
2. Fuel Price Adjustment (FPA)
Since fuel costs (oil, gas, coal, LNG) fluctuate constantly, NEPRA approves monthly adjustments:
How FPA Works
Reference Fuel Cost: The fuel cost assumed in the base tariff
Actual Fuel Cost: The real cost of fuel for that month
FPA = (Actual - Reference) per unit
Example: If reference was PKR 8/kWh and actual was PKR 11/kWh, FPA = +PKR 3/unit
FPA typically ranges from -PKR 3 to +PKR 8 per unit depending on global fuel prices. Recent trends show positive FPA due to rising LNG and coal prices.
3. Quarterly Tariff Adjustment (QTA)
Every quarter, NEPRA reviews actual costs vs projections and approves adjustments for:
- Power purchase price variations
- Transmission losses beyond allowed limits
- Distribution losses beyond allowed limits
- Variable O&M cost changes
4. Yearly Tariff Adjustment (YTA)
Annual adjustments to account for:
- Inflation
- Exchange rate changes
- Major cost revisions
5. Fixed Charges
A monthly charge based on your sanctioned load (in kW), regardless of consumption. This covers the cost of maintaining your connection to the grid.
| Consumer Category | Fixed Charges (PKR/kW/Month) |
|---|---|
| Protected (1-200 units) | Nil |
| Non-Protected (1-200 units) | 75 |
| Non-Protected (201-300 units) | 150 |
| Non-Protected (301-400 units) | 175 |
| Non-Protected (401+ units) | 350-400 |
| Commercial (A-2) | 440 |
| Industrial (B-2) | 380 |
Time-of-Use (ToU) Metering
ToU meters charge different rates based on time of day, incentivizing consumers to shift usage to off-peak hours:
| Time Period | Hours | Rate Impact | Best For |
|---|---|---|---|
| Peak | 6 PM - 10 PM | +25-30% higher | Essential use only |
| Normal | 6 AM - 6 PM | Standard rate | Regular usage |
| Off-Peak | 10 PM - 6 AM | -25-30% lower | Heavy appliances |
💡 Maximize ToU Savings
If you have ToU metering, schedule these for off-peak hours (10 PM - 6 AM):
- Washing machine and dryer
- Ironing (batch iron at night)
- Water pump/motor
- Electric water heater
- EV charging
Taxes and Surcharges
Multiple taxes and surcharges are added to your electricity charges:
General Sales Tax (GST)
- Up to 300 units: 0% GST (exempted)
- Above 300 units: 18% GST on the entire bill
Other Charges
| Charge | Rate | Purpose |
|---|---|---|
| Electricity Duty | 1.5% | Provincial tax |
| TV Fee | PKR 35/month | PTV license fee |
| FC Surcharge | Variable | Financing cost recovery |
| Neelum Jhelum Surcharge | PKR 0.10/unit | Dam construction |
| Financing Cost | Variable | Power sector debt servicing |
Why Your Bill Varies Each Month
Even with similar consumption, your bill can vary significantly due to:
- FPA Changes: Monthly fuel adjustments can add/subtract PKR 1-8 per unit
- QTA/YTA: Quarterly and yearly adjustments
- Crossing Slab Thresholds: Using 201 vs 199 units triggers Non-Protected rates
- Seasonal Consumption: Higher consumption in summer moves you to higher slabs
- Tariff Revisions: NEPRA revises base rates 1-2 times per year
- Billing Days: Billing periods aren't always exactly 30 days
📊 Example: Monthly Bill Variation
Month 1: 280 units, FPA = +3, QTA = +1
Variable: 280 × (27.14 + 3 + 1) = PKR 8,719
Month 2: 280 units, FPA = +6, QTA = +1
Variable: 280 × (27.14 + 6 + 1) = PKR 9,559
Difference: PKR 840 with SAME consumption!
How to Calculate Your Expected Bill

Subsidies and Special Categories
Protected Category Subsidy
Consumers with 6-month average consumption of 200 units or less receive heavily subsidized rates. This can save 50-80% compared to Non-Protected rates.
Lifeline Consumers
Consumers using 50 units or less per month get the lowest possible rates (approximately PKR 3.95/unit) with minimal taxes and surcharges.
Agricultural Subsidy
Agricultural tube wells receive subsidized rates to support farming sector. However, this subsidy has been gradually reduced over recent years.
Frequently Asked Questions
Who sets electricity tariffs in Pakistan?
NEPRA (National Electric Power Regulatory Authority) sets electricity tariffs after considering generation costs, transmission/distribution expenses, system losses, and government subsidies. They also approve monthly FPA and quarterly adjustments.
How does the slab system work?
Pakistan uses a progressive slab system where higher consumption attracts higher per-unit rates. For residential consumers, slabs range from 0-100 units (lowest rate) up to above 700 units (highest rate). When you cross certain thresholds, the higher rate applies to ALL units.
What is FPA and how does it affect my bill?
FPA (Fuel Price Adjustment) is a monthly adjustment that accounts for the difference between projected and actual fuel costs. When global fuel prices rise, FPA is positive (adds to your bill). When fuel prices drop, FPA can be negative (reduces your bill).
What is Time-of-Use (ToU) metering?
ToU metering charges different rates based on time of day. Peak hours (6 PM - 10 PM) have higher rates, while off-peak hours (10 PM - 6 AM) have lower rates (up to 30% less). This incentivizes shifting heavy usage to night hours.
Why does my bill vary even with similar consumption?
Bills vary due to monthly FPA changes, quarterly adjustments (QTA), yearly adjustments (YTA), crossing slab thresholds, seasonal tariff changes, and variations in billing period length.
