A positive rate adds a surcharge. A negative rate creates a credit.
What Is FPPAS in a UPPCL Electricity Bill?
FPPAS means Fuel and Power Purchase Adjustment Surcharge. It is a periodic adjustment used to reflect changes in power-purchase and transmission costs. Under the current regulatory mechanism, UPPCL publishes the applicable FPPAS separately for each billing month.
The percentage is not permanently fixed. It can be positive or negative. A positive percentage increases the eligible bill amount, while a negative percentage works as a credit and reduces it.
How to Use This UPPCL FPPAS Calculator
- Check the latest UPPCL FPPAS notice or your current bill.
- Enter the amount on which FPPAS applies.
- Enter the monthly FPPAS percentage exactly as published, including a minus sign when the rate is negative.
- Press Calculate FPPAS.
- Review the adjustment and estimated amount after FPPAS.
You can check current tariff and FPPAS notices on the official UPPCL tariff details page.
Example
If the FPPAS-applicable amount is ₹2,500 and the monthly rate is -2.33%, the adjustment is a credit of ₹58.25. If the rate were +4.27%, the same base would produce a surcharge of ₹106.75.
Why the FPPAS Rate Changes
The adjustment reflects differences between approved and actual power-purchase and transmission costs under the regulatory formula. Because those costs vary over time, using one permanent FPPAS percentage can give a misleading estimate.
Important Note
This calculator estimates only the FPPAS adjustment from the figures you enter. It is not a complete electricity bill calculator. Your final UPPCL bill may also include energy charges, fixed or demand charges, electricity duty, meter-related charges, rebates, arrears and other adjustments.
