🔬 What is FPA & How It Works

How FPA Is Calculated

NEPRA compares the actual fuel cost for the month against the reference fuel cost built into the base tariff. The difference (positive or negative) is passed to consumers as FPA.

FPA = (Actual Fuel Cost - Reference Fuel Cost) × Your Units

Why FPA Is High in Summer

During summer, Pakistan relies more on expensive furnace oil and gas generators due to peak demand. In monsoon, cheap hydel power kicks in, often reducing FPA. Winter sees moderate FPA levels.

💡 Reduce Your FPA Impact

📉 Consume Less in High-FPA Months

FPA peaks in June-August. This is exactly when ACs run full blast. Every unit saved in summer saves more due to high FPA + high slab rates.

☀️ Go Solar

Solar generation offsets grid units, meaning you pay less FPA. Self-generated solar has zero FPA cost.

Frequently Asked Questions

What is FPA (Fuel Price Adjustment)? ▼

FPA is a monthly charge that adjusts the electricity tariff based on actual fuel costs for power generation. When fuel costs exceed the reference rate built into tariffs, NEPRA adds a surcharge. When fuel costs are lower, you may get a credit.

Why does FPA change every month? ▼

Because fuel prices (oil, gas, coal, LNG) fluctuate globally. FPA reflects the actual cost of generating electricity each month vs. the budgeted cost in the base tariff.

Can FPA be negative? ▼

Yes! When actual fuel costs are lower than reference costs, FPA becomes negative — meaning a credit/discount on your bill. This typically happens when hydel (water) generation is high during monsoon.

How much does FPA add to my bill? ▼

FPA is charged per unit consumed. At ₨3-4/unit FPA, a household using 300 units pays an extra ₨900-1,200/month just in FPA.
