LESCO FCA in August Bill: Rs0.75 Per Unit Explained

The FCA line on your August 2026 LESCO bill is Rs0.7503 per unit. It is not a rate NEPRA invented for August. It is the gap between the fuel cost already built into your tariff — Rs7.7138 per unit — and what June’s electricity actually cost to generate, Rs8.4641 per unit. You are paying that difference on every unit this month.

Most explanations stop at “FCA reflects fuel prices.” That skips the part that actually tells you whether the number is fair. Your bill already assumes a fuel cost. The FCA only exists to settle the difference between that assumption and reality.

Where the Rs0.7503 actually comes from

Your base tariff is not fuel-free. Buried inside the rate NEPRA notified for the year is a reference fuel cost of Rs7.7138 per unit — the price power generation was assumed to cost when the tariff was set.

June’s generation did not cost that. After reviewing the data, NEPRA fixed the actual fuel cost for June at Rs8.4641 per unit.

Subtract one from the other:

Rs8.4641 − Rs7.7138 = Rs0.7503

That is your FCA. It is positive only because June’s real fuel cost ran above the reference. In a month where generation is cheaper than the reference — more hydel, softer LNG prices — the same line turns negative and lands as a credit.

Why it was cut from Rs1.20 to Rs0.7503

The number you are paying is not the number CPPA-G asked for.

The Central Power Purchasing Agency filed for Rs1.20 per unit, based on a claimed June fuel cost of Rs8.9138 per unit. Run the same subtraction on their figure and it lands exactly on their ask:

Rs8.9138 − Rs7.7138 = Rs1.20

NEPRA did not accept the claim as filed. It scrutinised the workings — including a disputed energy import from Iran’s Tavanir and a reported generation shortfall against target — and marked the real fuel cost down to Rs8.4641. That single correction, Rs0.45 knocked off the claimed cost, is the whole distance between a Rs1.20 bill and a Rs0.75 one. Across the country it is the difference between roughly Rs9.8 billion recovered and considerably more.

Reference, claim, and ruling in one view:

How to check the FCA on your own bill

Find the line marked FCA, FPA, or Fuel Price Adjustment in the charges breakdown. It carries a per-unit rate. The rupee figure is simply that rate times the units on this bill:

• 200 units → 200 × 0.7503 = Rs150, plus 18% GST = Rs177
• 300 units → 300 × 0.7503 = Rs225, plus 18% GST = Rs266
• 500 units → 500 × 0.7503 = Rs375, plus 18% GST = Rs443

Two things people miss. First, GST rides on top of the FCA at 18%, so the line costs a little more than the rate alone suggests. Second, the rate is applied to August’s units, even though the fuel it settles was burned in June. The fuel month and the units it is charged against are not the same month — that gap is why a quiet month can still arrive expensive, covered on the main bill guide.

Is Rs0.75 actually high?

On its own the number means little. Against the rest of 2026 it is on the low side.

The July figure has not been finalised, but early filings point sharply upward on heavier peak-hour reliance on spot LNG and furnace oil. If you are budgeting, treat this Rs0.75 as a mild month, not the ceiling.

FPA or FCA — is it the same line?

Yes. The regulator’s notification says Fuel Charges Adjustment. Many printed LESCO bills label the same line Fuel Price Adjustment or FPA. One charge, two names, identical number. There is no separate FPA hiding elsewhere on the sheet.

Who does not pay it

The Rs0.7503 applies to nearly every category, including consumers under the incremental consumption package. Three groups are exempt: lifeline consumers, EV charging stations, and prepaid consumers who opted for the prepaid tariff. Protected domestic status does not exempt you — only lifeline does. The exemption lists differ from those on the quarterly adjustment, and the September relief breakdown sets the two side by side.
