1. Introduction to K-Electric Tariff Framework
KK-Electric (formerly Karachi Electric Supply Company - KESC) is Pakistan’s largest vertically integrated electric utility, providing generation, transmission and distribution services to over 3.4 million customers in Karachi, Dhabeji, Gharo and parts of Balochistan including Hub. With the complex structure of K-Electric tariff slabs and per-unit rates, it is essential for households, businesses and industrial units to understand how to control electricity costs.
Electricity billing in Pakistan is regulated strictly by the National Electric Power Regulatory Authority (NEPRA). Electricity billing in Pakistan uses a slab‑based progressive rate mechanism. Under this system when your consumption crosses monthly unit thresholds measured in kilowatt‑hours the base per‑unit cost rises for all or subsequent billing brackets. Electricity billing in Pakistan also includes national tariffs, fuel cost adjustments (FCA) dynamic surcharges and government taxes all of which are part of the final payable amount, on your monthly bill.
2. Protected vs Unprotected Consumers Category
To protect low-income households from the rising energy inflation, NEPRA along with the Ministry of Energy has introduced a separate classification system which further categorizes residential electricity consumers into two broad categories: Protected Category and Unprotected Category.
Protected Consumers
A residential consumer falls under the Protected Category if their monthly electricity consumption has remained at or below 200 units continuously for the last 6 consecutive months.
- Highly subsidized base electricity tariff.
- Lower burden of fuel price adjustments.
- Exemption from heavy fixed capacity charges.
Unprotected Consumers
A consumer is classified as Unprotected if their consumption exceeds 200 units in any single month within a 6-month billing window.
- Significantly higher base unit pricing.
- Complete removal of governmental base subsidies.
- Rapid tariff scaling once passing 300 & 700 units.
Critical Tip: The 200-Unit Threshold Warning
If your consumption stays at 195 units for 5 months but hits 205 units on the 6th month, your status instantly switches from Protected to Unprotected. This one spike will raise your base rate for future bills. So you pay a lot more in total than just those extra 5 units.
3. Residential Tariff Unit Rates & Price Slabs Break up
Residential electricity rates (Tariff A-1) are divided into billing slabs, starting with the lowest. The table below provides a full breakdown of average base unit tariffs effective across K-Electric's network. Note: Rates represent base electricity charges approved by NEPRA prior to fuel adjustments and government taxes.
Residential Tariff Structure (Tariff A-1)
| Consumer Category | Slab Range (Units/Month) | Base Unit Rate (PKR / kWh) | Fixed Charge (PKR/Month) |
|---|---|---|---|
| Protected Category | 1 – 100 Units | Rs. 11.69 | Nil / Nominal |
| 101 – 200 Units | Rs. 14.16 | Nil / Nominal | |
| Unprotected Category | 1 – 100 Units | Rs. 23.59 | Rs. 200 – 400 |
| 101 – 200 Units | Rs. 30.07 | Rs. 400 | |
| 201 – 300 Units | Rs. 34.26 | Rs. 400 | |
| 301 – 400 Units | Rs. 39.15 | Rs. 600 | |
| 401 – 500 Units | Rs. 41.36 | Rs. 800 | |
| 501 – 600 Units | Rs. 42.78 | Rs. 1,000 | |
| High Consumption | 601 – 700 Units | Rs. 43.92 | Rs. 1,000 |
| Maximum Peak Slab | Above 700 Units | Rs. 48.84 | Rs. 1,000 |
* Note: The applicable rates are subject to periodic NEPRA adjustments, Quarterly Tariff Adjustments (QTA) and Fuel Cost Adjustments (FCA).
4. Commerce, Industry & Agriculture Tariffs
Commercial, industrial and agricultural enterprises are served under separate tariff schedules dependent on demand characteristics, load connections and system capacity needs.
A. Commercial Power Tariff (A-2)
Commercial relationships are grouped by approved carrying capacity:
- Commercial A-2 (a) [For Sanctioned Load up to 5 kW]: Billed at a uniform base per-unit rate between Rs. 39.00 to Rs. 45.00 per kWh, plus minimum monthly fixed charges.
- Commercial A-2 (b) [For Sanctioned Load > 5 kW]: Time-of-Use (TOU) metering with separate peak and off-peak rates, and fixed capacity rates based on Maximum Demand Indicator (MDI) in kW per month.
B. Industrial Tariff Categories (B1, B2, B3, B4)
| Tariff Category | Sanctioned Load Range | Metering Type | Key Features |
|---|---|---|---|
| B1 / B1(a) | Up to 25 kW | Single/Three Phase Standard | Fixed rates per kWh for small workshops & cottage units. |
| B2 / B2(b) | 25 kW to 500 kW | TOU + MDI Metering | Peak & Off-peak segmentation with MDI charges. |
| B3 | 500 kW to 5,000 kW (11 kV) | High Voltage TOU | Dedicated feeders, bulk industrial processing units. |
| B4 | All loads at 66 kV / 132 kV | Extra High Voltage TOU | Heavy manufacturing, steel mills, and chemical plants. |
C. Agriculture & Other Connections
Agricultural tubewells (Tariff D) benefit from government agricultural relief packages designed to lower irrigation costs. Temporary connections (Tariff E) are for construction sites or temporary events and they are charged a higher flat unit charge without any slab-based subsidies.
5. 5. Time of Use (TOU): Peak vs. Off-Peak Hours
For consumers having 3-phase connections or having a sanctioned load of more than 5 kW (and residential TOU meters), K-Electric divides the 24-hour daily cycle into Peak Hours and Off-Peak Hours.
Understanding TOU Pricing Structure Peak Hours
Peak Hours: Peak hours are the hours of high demand when the cost of generation of electricity goes up. The unit rates during peak hours are significantly higher.
Off-Peak Hours: Off‑peak hours are the part of the day when the total demand on the electricity grid goes down. Because the grid is less busy the price per unit of electricity is lower during off‑peak hours.
K-Electric Peak Hours Schedule
| Season / Months | Peak Hours Duration | Total Peak Hours |
|---|---|---|
| April to September (Summer) | 6:30 PM to 10:30 PM | 4 Hours Daily |
| October to March (Winter) | 6:00 PM to 10:00 PM | 4 Hours Daily |
High‑power equipment such as air conditioners, electric water heaters, pumps and heavy machinery use a lot of electricity during peak hours. Using these devices during peak hours can raise your bill by a large amount. Shifting the use of these devices to off‑peak hours is a way to keep energy costs low.
6. Fixed Charges, Fuel Adjustments (FCA) & Government Taxes
Your K‑Electric bill is not, about the basic electricity usage. A large portion of the amount comes from surcharges, adjustments and government taxes that are added on top of the base price.
Fuel Cost Adjustment (FCA)
Fuel Cost Adjustment (FCA) is a way to handle changes in the price of fuels such as LNG, coal, furnace oil and gas that power plants use. NEPRA checks the fuel price each month. Then adds or subtracts an FCA charge for each unit on the next bill.
Quarterly Tariff Adjustment (QTA)
Quarterly Tariff Adjustment (QTA) is set each quarter. It takes into account capacity charges, transmission losses and the price differences in power purchases across the grid.
Financing Cost Surcharge (FCS)
Financing Cost Surcharge (FCS) is a fee, per unit that all power distribution companies add. The FCS helps cover the debt that the power sector owes and the payment of debt.
Electricity Duty (ED) & Sales Tax
Electricity Duty (ED) and Sales Tax are taxes that the government charges. Electricity Duty (ED) is usually 1.5% of the electricity charge. General Sales Tax (GST) is 18%. Is calculated on the total energy charge plus any surcharges.
Non-energy charges and taxes – an overview
- General Sales Tax (GST): The standard rate applicable is 18% on all the items mentioned in the invoice.
- Fee for TV: Rs. 35 for residential and Rs. 60 for commercial (flat rate).
- Advance Income Tax (Under Section 235): Advance Income Tax (Section 235) on non tax filers or bills exceeding certain monthly limit (e.g. bills exceeding Rs. 25,000/month).
- KMC Municipal Utility Charges: KMC Municipal Utility Charges The charges applied by Karachi Metropolitan Corporation, according to the type of connection.
7. How to check a Sample Bill Step by Step
Now let us consider an example of Unprotected Residential Consumer who uses 350 units and understand the method of calculation based on unit rate, slab structure and taxes.
Working Out the Calculation (Consumption of 350 Units)
| Slab Range | Units | Applicable Base Rate | Total Base Cost (PKR) |
|---|---|---|---|
| 1 – 100 Units | 100 | Rs. 23.59 | Rs. 2,359.00 |
| 101 – 200 Units | 100 | Rs. 30.07 | Rs. 3,007.00 |
| 201 – 300 Units | 100 | Rs. 34.26 | Rs. 3,426.00 |
| 301 – 350 Units | 50 | Rs. 39.15 | Rs. 1,957.50 |
| Subtotal Variable Base Cost: | Rs. 10,749.50 | ||
Additional Taxes & Surcharges Estimation:
- Fixed Capacity Charges Rs. 600.00
- Estimated FCA & Tariff Adjustments (~Rs. 3.50/unit) Rs. 1,225.00
- Electricity Duty (ED) & Surcharges Rs. 450.00
- General Sales Tax (GST @ 18%) Rs. 2,344.00
- PTV Fee & Municipal Taxes Rs. 150.00
8. Helpful Tips to Cut Your K-Electric Unit Consumption
With rising electricity tariffs, it’s wise to be proactive to optimize your energy use in your household and business to help keep your bill in the lower tariff brackets:
Optimize Air Conditioning
Set air-conditioners (inverter) to 26°C. For each 1 degree below 26°C, energy use increases about 6%. Keep your filters clean for good airflow.
Go for solar net metering
Net Metering enables you to install a grid tied solar system to sell excess generation back to K-Electric, directly offsetting daytime peak consumption.
Eliminate Phantom Load
When not in use, unplug electronics like chargers, TVs and microwave ovens. Standby power consumption can cost you an extra 5% to 10% on your monthly bill.
Move large loads off-peak.
Avoid running water pumps, washing machines, irons and heavy appliances during daily peak hours (6:30 PM – 10:30 PM in summer).
