Updated: August 2026
The FPA in your electricity bill is the Fuel Price Adjustment, and it is the reason your bill changes even when your units don’t. In July 2026 bills, the FPA line added Rs 0.3364 per unit for consumers of all DISCOs and K-Electric. August bills could carry a much bigger FPA of up to Rs 1.20 per unit — NEPRA heard that petition on 29 July 2026 and its final decision was still awaited as of early August. On 300 units, the difference between those two months is roughly Rs 260 before tax. Same house, same usage, different bill.
What is FPA? (quick answer): FPA (Fuel Price Adjustment), also written as FCA (Fuel Charges Adjustment), is a monthly charge or credit on Pakistani electricity bills. It recovers the gap between the fuel cost NEPRA assumed in your tariff and the fuel actually burned to generate electricity two months earlier, and NEPRA approves it after a public hearing.
This guide covers how the number is worked out, every FCA decision of 2026 so far in one refreshable table, who is exempt, what FPA looks like on a K-Electric bill versus a LESCO or MEPCO bill, and exactly what it costs you on a 300-unit month.
FPA and FCA are the same thing
Your bill may print it as “FPA”, “F.P.A”, “Fuel Price Adjustment” or “Fuel Cost Adjustment”. NEPRA’s own decisions call it FCA — Fuel Charges Adjustment. All four names refer to one mechanism, so if you searched for “fca in electricity bill” you are in the right place.
Here is why it exists. When NEPRA sets the base tariff, it assumes a certain fuel cost per unit — the reference fuel cost. That assumption is baked into the per-unit rates you can see in our guide to the electricity per unit price in Pakistan. Real life rarely matches the assumption. Furnace oil and RLNG prices move, the rupee moves, hydel output rises and falls with river flows, and plants go on maintenance. Whatever the actual fuel cost turns out to be, the difference between actual and reference is passed to consumers as FPA.
Two things follow from that design:
- FPA is not a tax and not a penalty. It is a cost true-up. Taxes are a separate stack on your bill, covered in our breakdown of taxes on electricity bills in Pakistan.
- FPA can be negative. When cheap hydel and nuclear dominate the generation mix, actual fuel cost comes in below reference and you get a credit. It happened in 2026, though only just — more on that below.
How NEPRA calculates the monthly FPA
The process runs on a fixed monthly cycle and always lands on your bill about two months after the electricity was generated.
- CPPA-G files a petition. The Central Power Purchasing Agency (Guaranteed), which buys power on behalf of the ex-WAPDA distribution companies (XWDISCOs), submits the actual generation data and fuel cost for the month to NEPRA and requests an adjustment.
- NEPRA holds a public hearing. The authority examines which plants ran, on what fuel, and whether expensive generation was justified. Anyone can attend or comment.
- NEPRA determines the FCA. The formula is simple: actual fuel cost per unit minus reference fuel cost per unit. The scrutiny is in the “actual” number — NEPRA routinely disallows costs it finds imprudent.
- The decision is notified. It is published on NEPRA’s website with the exact paisa-per-unit figure and the list of exempt consumer categories.
- It appears on your bill two months later. The FCA for June is charged in August bills, July’s in September bills, and so on. One detail most people miss: NEPRA’s decisions apply the rate to the units you were billed in the fuel month itself, not the current month. If you used 250 units in June and 400 in August, the June FCA on your August bill is calculated on 250 units.
May 2026 shows the scrutiny step in action. CPPA-G asked for a positive FCA of 81.73 paisa per unit, claiming an actual fuel cost of Rs 9.2488 against a reference of Rs 8.4315. NEPRA went through the generation data and determined the actual cost at Rs 8.7679 instead, approving only 33.64 paisa per unit — less than half the ask. That saved consumers about 48 paisa on every unit in July bills.
FPA rates in 2026: month-by-month tracker
This table lists every monthly FCA decision of 2026 so far. Bookmark it — we update it as each new NEPRA decision lands.
| Fuel month | FPA / FCA (Rs per unit) | Charged in bills of | Status and notes |
|---|---|---|---|
| January 2026 | +1.6274 | March 2026 | Approved. Recovered around Rs 14 billion from consumers of DISCOs and K-Electric. |
| February 2026 | +1.4235 | April 2026 | Approved. Roughly Rs 10.57 billion impact; applied to all consumers including K-Electric except exempt categories. |
| March 2026 | −0.0102 | May 2026 | Approved. A rare negative FPA — a small credit. CPPA-G had actually asked for a +0.2660 increase; NEPRA’s scrutiny turned it into relief. |
| April 2026 | +1.1907 | June 2026 | Approved in early June 2026. |
| May 2026 | +0.3364 | July 2026 | Approved 8 July 2026. CPPA-G had sought 81.73 paisa; NEPRA allowed less than half, an impact of about Rs 4.2 billion. |
| June 2026 | +1.20 (requested) | August 2026 | Pending. Hearing held 29 July 2026; the reference fuel cost was Rs 7.71 per unit, the actual around Rs 8.90. Final figure awaited as of 4 August 2026. |
A few patterns worth noticing. First, five of six months were positive — expensive RLNG generation kept actual costs above reference through most of the year. Second, the number swings hard: from Rs 1.63 down to almost zero and back up again within four months. Third, NEPRA trimmed the request in several months, so the figure CPPA-G asks for in the news is often not the figure you end up paying. The June petition works out to about Rs 15.7 billion if approved in full, spread over the 13.07 billion units sold that month. And because July’s 34-paisa FPA drops out of bills at the same time, the net swing in August would be about 86 paisa per unit, not the full Rs 1.20.
Some relief ran in parallel: NEPRA approved a negative quarterly adjustment (QTA) of Rs 1.9857 per unit for January–March 2026, worth about Rs 67 billion, credited in June, July and August 2026 bills. QTA is a separate quarterly mechanism that trues up capacity and other non-fuel costs, which is why your June and July bills may have shown both an FPA charge and a larger QTA credit at the same time.
What FPA costs on a 300-unit bill
Multiply the month’s FPA rate by your billed units, then add 18% GST, which is charged on the FPA amount like the rest of your bill. Here is the same 300-unit home across every 2026 billing month:
| Billing month | FPA rate (Rs/unit) | FPA on 300 units | GST @ 18% | Total FPA impact |
|---|---|---|---|---|
| March 2026 | +1.6274 | Rs 488.22 | Rs 87.88 | Rs 576.10 |
| April 2026 | +1.4235 | Rs 427.05 | Rs 76.87 | Rs 503.92 |
| May 2026 | −0.0102 | −Rs 3.06 | −Rs 0.55 | −Rs 3.61 |
| June 2026 | +1.1907 | Rs 357.21 | Rs 64.30 | Rs 421.51 |
| July 2026 | +0.3364 | Rs 100.92 | Rs 18.17 | Rs 119.09 |
| August 2026 | +1.20 (if approved) | Rs 360.00 | Rs 64.80 | Rs 424.80 |
Walk through July as an example: 300 units × Rs 0.3364 = Rs 100.92. GST at 18% adds Rs 18.17, so the FPA cost you Rs 119.09 in total. In March the same 300 units carried Rs 576.10. That Rs 457 swing had nothing to do with your usage — it was entirely the fuel mix two months earlier. When a negative FPA lands, as in May, the credit also reduces the tax calculated on your bill, which is why the May row shows a small negative GST figure too.
Remember the technical detail from the calculation section: the rate applies to the units you were billed in the fuel month, not the billing month. The table assumes steady 300-unit consumption, which keeps the arithmetic honest for a typical home.
Positive vs negative FPA
Positive FPA means actual fuel cost beat the reference — you pay extra. The usual culprits are RLNG and furnace-oil plants running harder than planned, a weaker rupee making imported fuel dearer, or low hydel flows. At the June 2026 hearing, CPPA-G blamed RLNG generation that cost around Rs 35 per unit, more than double the Rs 16 of a year earlier.
Negative FPA means the grid ran cheaper than assumed — you get a per-unit credit. High hydel season, strong nuclear availability and soft international fuel prices produce negative months. March 2026’s credit of 1.02 paisa per unit was tiny, but 2025 and earlier years saw far larger negative adjustments, sometimes above a rupee. A negative FPA appears on your bill with a minus sign or in brackets and reduces the amount payable.
There is no cap or floor set in advance. Each month stands on its own data, which is exactly why the tracker table above is worth checking before you panic about a high bill. If your bill jumped and the FPA line doesn’t explain it, the usual suspects are slab jumps, estimated meter readings and seasonal load — our guide to why electricity bills run high in Pakistan walks through each one.
Who is exempt from FPA in 2026?
NEPRA’s 2026 FCA decisions apply the adjustment to all consumer categories of K-Electric and the ex-WAPDA DISCOs except three groups:
| Category | Exempt from positive FPA? | Why |
|---|---|---|
| Lifeline consumers (protected low-usage domestic, typically up to 100 units) | Yes | Shielded as a matter of policy in every 2026 decision. |
| Electric Vehicle Charging Stations (EVCS) | Yes | Charged a fixed tariff to encourage EV infrastructure. |
| Prepaid electricity consumers | Yes | Their tariff is locked at purchase, so retrospective adjustments don’t apply. |
| Protected domestic consumers (up to 200 units for 6 months) | No | They pay lower base rates but the FPA line still applies. |
| All other domestic, commercial, industrial, agricultural consumers | No | FPA applies in full. |
The protected-consumer row surprises people. In some earlier years NEPRA exempted domestic consumers up to 300 units from particular positive FCAs, and old articles still float around claiming that exemption exists. The 2026 decisions do not include it: only lifeline, EVCS and prepaid consumers are spared. If you are not sure which side of the protected line you fall on, read our explainer on protected vs unprotected electricity consumers — that status changes your base rate, but not whether FPA applies.
Note the mirror image for relief months: the January–March 2026 QTA credit excluded lifeline, prepaid and incremental-package consumers, so exemption lists cut both ways. Solar homes are not exempt either — under net metering, FPA applies to whatever net units you are billed after exports are offset.
FPA on K-Electric vs DISCOs
For years K-Electric ran on its own FCA track. KE generates part of its power itself and buys the rest, so NEPRA determined its fuel adjustments separately, often notifying them months after the fuel was burned.
That gap has effectively closed. Throughout 2026, NEPRA has issued combined FCA decisions covering K-Electric and the XWDISCOs together, with a single uniform rate, in line with the government’s uniform-tariff policy. The Rs 1.4235 February adjustment, the Rs 1.1907 April adjustment and the 33.64 paisa May adjustment all applied identically in Karachi and in LESCO, MEPCO, FESCO, IESCO, GEPCO, PESCO, HESCO, SEPCO, QESCO and TESCO territory.
So a Karachi consumer’s FPA line now matches a Lahore consumer’s for the same billing month. What still differs is presentation: KE prints its own bill format, and occasional KE-specific true-ups from older periods can appear as separate line items.

How to spot FPA in your electricity bill
On the standard PITC-printed DISCO bill, look at the charges block on the left half of the page:
- The line labelled “FPA” or “F.P.A” sits below your energy cost and above the tax rows. It shows the rupee amount, and many DISCOs also print the fuel month it pertains to (for example “FPA JUN-26” on an August bill).
- GST on FPA is included in the sales-tax row. Some formats show it separately as “GST on FPA”.
- A negative FPA appears with a minus sign or brackets and pulls the total down.
- Zero-FPA months exist — if NEPRA hasn’t notified an adjustment in time for the billing run, the line may show 0 and the amount is picked up in a later bill.
On K-Electric bills the line usually reads “Fuel Surcharge Adjustment” or “FCA” inside the charges summary.
If your paper bill is missing, every DISCO’s duplicate bill shows the same FPA detail. You can pull a LESCO duplicate bill or any other company’s copy in a few seconds and compare the FPA line against the tracker table above. If the rate on your bill doesn’t match the notified figure for that month, that is worth a complaint to your DISCO’s customer service.
One more sanity check: FPA sits on top of the base tariff, which NEPRA set at a national average of Rs 33.38 per kWh in January 2026, with interim tariff arrangements reported for July to December 2026. So when your bill moves month to month with steady usage, FPA and quarterly adjustments are almost always the moving parts, not the base rate.
FAQs
Is FPA the same as FCA?
Yes. FPA (Fuel Price Adjustment) and FCA (Fuel Charges Adjustment) are two names for the same monthly mechanism. NEPRA’s official decisions say FCA; most DISCO bills print FPA. Some bills and news reports also write “fuel cost adjustment” — all of them refer to the identical per-unit figure.
Why does my August bill show FPA for June?
The cycle needs time: June’s generation data is compiled in July, CPPA-G petitions NEPRA, a public hearing is held, and the decision is notified — about two months in total. So the FPA on your August 2026 bill trues up June’s fuel costs, calculated on the units you were billed in June.
Are protected consumers exempt from FPA?
No. In NEPRA’s 2026 FCA decisions, only lifeline consumers, Electric Vehicle Charging Stations and prepaid consumers are exempt. Protected domestic consumers (up to 200 units a month) pay lower base rates but still pay the monthly FPA. Claims that consumers under 300 units are exempt refer to older, expired decisions.
Can FPA be negative, and do I get a refund?
Yes. When the actual fuel cost comes in below the reference cost, NEPRA notifies a negative FPA and your bill is credited that many paisa per unit. In May 2026 bills, consumers received a small credit of 1.02 paisa per unit for March. The credit also reduces the tax calculated on your bill. It arrives as a bill adjustment, not a cash refund.
Is GST charged on the FPA amount?
Yes. Sales tax at 18% applies to the FPA amount just as it does to your energy charges. On a Rs 360 FPA line, GST adds Rs 64.80, taking the true cost to Rs 424.80. Duties and other levies can apply too, depending on your province and category.
Does K-Electric charge a different FPA than LESCO or MEPCO?
Not any more for current months. Through 2026, NEPRA has issued uniform FCA decisions covering K-Electric and all ex-WAPDA DISCOs at the same rate — February’s Rs 1.4235, April’s Rs 1.1907 and May’s Rs 0.3364 applied nationwide. KE bills may still carry separate line items for older KE-specific true-up periods.
Do solar net-metering users pay FPA?
FPA is charged on the units you are billed for. Under net metering, your exported units offset your imports first, so FPA applies only to the net billed units. In a month where you export more than you import, there are no billed import units for FPA to attach to.
How much FPA will I pay on 300 units in August 2026?
If NEPRA approves the requested June adjustment of Rs 1.20 per unit in full, 300 units would carry Rs 360 of FPA plus Rs 64.80 GST — about Rs 425. NEPRA trimmed several 2026 requests, so the final figure may be lower; check the notified rate on your bill against our tracker table.
