What is IESCO?

Understanding IESCO Billing Adjustments
Have you ever noticed extra charges appearing suddenly on your bill?
Usually, these come from billing adjustments.
Common Adjustments Include
- Fuel Price Adjustment (FPA)
- Quarterly Tariff Adjustment (QTA)
- GST
- TV Fee
- Meter rent
- Deferred charges
What is FPA?
Fuel Price Adjustment reflects changes in fuel costs used for electricity generation.
So if fuel prices increase nationally, your bill may increase too — even if your unit consumption stays similar.
IESCO Peak Hours
Peak hours are the times when electricity demand becomes very high.
Using heavy appliances during these hours can increase your bill significantly.
Typical Peak Hours
| Season | Peak Timing |
|---|---|
| April to October | 6 PM – 10 PM |
| November to March | 5 PM – 9 PM |
