When the actual fuel cost of generating electricity exceeds the reference fuel cost already included in the tariff, consumers are charged an additional amount known as Fuel Cost Surcharge (FCS).
This adjustment is approved by the National Electric Power Regulatory Authority (NEPRA) and is reflected in monthly electricity bills issued by distribution companies, including LESCO.
Why Is FC Surcharge Charged?
The primary purpose of fuel cost adjustment is to recover fluctuations in power generation costs.
Fuel prices in international and local markets change regularly. When power plants spend more money on fuel than initially estimated, the difference is passed on to electricity consumers through the surcharge.
The following factors can increase the surcharge:
| Factor | Impact on Electricity Cost |
|---|---|
| Increase in LNG prices | Higher generation cost |
| Rise in coal prices | Increased fuel expenses |
| Expensive furnace oil | Higher power production cost |
| Currency depreciation | Increased imported fuel cost |
| Reduced hydropower generation | Greater dependence on thermal power |
These changes directly influence the FC Surcharge on Your LESCO Bill and can significantly affect monthly electricity expenses.

Where Can You Find FC Surcharge on a LESCO Bill?
The surcharge is usually listed in the bill details section under names such as:
- Fuel Cost Adjustment (FCA)
- Fuel Price Adjustment
- FC Surcharge
- Fuel Charges Adjustment
The exact wording may vary depending on the billing period and regulatory directives.
Consumers should carefully review the adjustment section because this charge can add a noticeable amount to the total bill.
How Is FC Surcharge Calculated?
The calculation is generally based on the number of electricity units consumed and the approved fuel cost adjustment rate.
The basic formula is:
| Calculation Component | Formula |
|---|---|
| FC Surcharge | Units Consumed × Approved FCA Rate |
For example:

| Detail | Value |
|---|---|
| Electricity Units | 500 Units |
| FCA Rate | Rs. 2.50 per Unit |
| FC Surcharge | Rs. 1,250 |
In this example, the consumer will pay an additional Rs. 1,250 due to fuel cost adjustments.
The actual rate changes every month based on NEPRA notifications.
Does Every Consumer Pay FC Surcharge?
Not always.
The applicability of fuel cost adjustment depends on government policies, consumer categories, and NEPRA decisions. In some cases, protected consumers may receive exemptions or reduced adjustments.
The following categories may be affected differently:
| Consumer Category | FC Surcharge Applicability |
|---|---|
| Domestic Consumers | Usually Applicable |
| Commercial Consumers | Applicable |
| Industrial Consumers | Applicable |
| Agricultural Consumers | Depends on Policy |
| Protected Consumers | May Receive Relief |
Consumers should check the latest notification and their bill details to confirm whether the charge applies to them.

How Much Does FC Surcharge Affect Your Total Bill?
The impact varies every month. During periods of high fuel prices, the surcharge can significantly increase the final bill amount.
For example:
| Units Consumed | FCA Rate | Additional Cost |
|---|---|---|
| 200 Units | Rs. 2.00 | Rs. 400 |
| 400 Units | Rs. 2.00 | Rs. 800 |
| 600 Units | Rs. 2.00 | Rs. 1,200 |
| 800 Units | Rs. 2.00 | Rs. 1,600 |
As electricity consumption rises, the surcharge increases proportionally.
If you want a quick estimate of your monthly charges, you can use online billing tools to see how FC surcharge affects your total before receiving your official bill.
Who Decides the FC Surcharge Rate?
The surcharge rate is determined through a regulatory process involving NEPRA and power sector authorities.
The process generally follows these steps:
- Electricity generation companies submit fuel cost data.
- Actual generation costs are compared with reference costs.
- NEPRA conducts a review and public hearing if required.
- The adjustment amount is approved.
- Distribution companies apply the approved rate to consumer bills.
This mechanism ensures that electricity tariffs reflect actual fuel costs incurred during power generation.
Can FC Surcharge Be Negative?
Yes. In some months, fuel prices may be lower than the reference cost used in tariff calculations. In such situations, consumers can receive a negative fuel cost adjustment.
A negative adjustment appears as a deduction rather than an additional charge and reduces the overall electricity bill.

How Can Consumers Reduce the Impact of FC Surcharge?

Some practical steps include:
- Use energy-efficient appliances.
- Replace conventional bulbs with LED lighting.
- Turn off unused electrical equipment.
- Avoid unnecessary air conditioner usage.
- Schedule high-load appliances wisely.
- Improve insulation to reduce cooling requirements.
Lower electricity consumption means fewer units are subject to fuel cost adjustments.
