If your October 2026 electricity bill already felt heavier, brace yourself — November is shaping up to sting more. The Power Division has projected a **fuel cost adjustment (FCA) of Rs2.56 per unit** for electricity consumed in September, a charge expected to land on November bills and add roughly **Rs32.7 billion** to what households and businesses across Pakistan collectively pay.

That comes right on the heels of the **Rs1.11 per unit FCA** NEPRA already notified for October bills. Two hikes in two months tells you something important: the grid is getting more expensive to feed, and every rupee of that cost is being passed straight to you. The quiet counterpoint is that each FCA increase makes one thing more valuable than ever — the solar unit you generate and use yourself, which the fuel cost adjustment can never touch.

What exactly is this Rs2.56 FCA?

The fuel cost adjustment is the gap between the *reference* fuel cost baked into your tariff and the *actual* cost of the fuel burned to generate your electricity. When power companies rely more on expensive imported fuel, that gap widens and the regulator allows them to recover it from consumers.

For September, the projected FPA of Rs2.56 per unit is **Rs1.45 higher than August's adjustment**. The culprit was heavier dependence on costly furnace oil and high-speed diesel. NEPRA is scheduled to hear the Central Power Purchasing Agency's request on **29 October 2026**, so the final figure may shift slightly before it is notified.

It could have been far worse. The Power Division says targeted load management of two to two-and-a-half hours a day, plus supplying imported RLNG at domestic gas prices, shaved the adjustment down from a potential Rs5–6 per unit to Rs2.56.

In other words, even after mitigation, consumers are absorbing Rs2.56 extra per unit. The structural problem — an expensive, fuel-dependent grid — is not going away.

Why FCA makes solar self-consumption more valuable

Here is the point most bill-payers miss. **The FCA is charged only on units you import from the grid.** Every kilowatt-hour your rooftop solar system produces and you consume on the spot never passes through a meter as "imported" power — so it carries:

  • No base per-unit tariff
  • No fuel cost adjustment (neither the Rs1.11 nor the Rs2.56)
  • No quarterly tariff adjustments
  • No electricity duty, GST, or financing surcharges layered on top

When the grid tariff rises, the *avoided cost* of each self-consumed solar unit rises with it. A unit you don't buy from WAPDA/K-Electric at, say, Rs60+ all-in is worth far more to you than the same unit exported to the grid.

That gap matters especially now because of the **shift from net metering to net billing**. Under the Prosumer Regulations 2026 (notified 9 February 2026), new solar consumers export surplus power at a buyback rate of around **Rs8.13 per unit** — down from the old one-for-one netting worth roughly Rs25–27. Exporting is no longer the prize. Using your own generation is.

Self-consumption vs. export: the new maths

The table below shows why the strategy has flipped under net billing — and why rising FCAs reinforce it.

| What you do with a solar unit | Approximate value to you (2026) | Affected by FCA hikes? | |---|---|---| | Consume it yourself (offset grid import) | Rs55–65+ (full avoided tariff) | Yes — value rises with every hike | | Export it to the grid (new net-billing prosumer) | ~Rs8.13 buyback | No — fixed, low | | Export it (grandfathered net-metering, pre-9 Feb 2026) | ~Rs25.32 | No | | Import it from the grid | You pay it (plus Rs2.56 FCA in Nov) | Yes — you absorb the hike |

Read the first and last rows together. A self-consumed unit is now worth close to **seven to eight times** a newly exported one. Every FCA rupee added to the import tariff pushes that first-row number higher while the export rate stays flat. The regulatory change and the fuel-cost trend both point the same way: **size your system for daytime self-consumption, not for selling back.**

A practical example for a Lahore household

Consider a home consuming 1,000 units a month, mostly during daylight hours (fans, air conditioning, water pumps, refrigeration).

  • A **10kW on-grid solar system** currently costs roughly **PKR 950,000 to 1,200,000** installed, with panels around Rs38–40 per watt.
  • Such a system can realistically generate 1,100–1,400 units a month in Pakistan's sunshine.
  • If you time your heavy loads to the day and self-consume most of that output, you avoid buying those units from the grid at full tariff — **including the Rs2.56 FCA now and whatever comes next.**

At roughly Rs55–65 per avoided unit, offsetting ~1,000 units saves on the order of **Rs55,000–65,000 a month**, pushing payback for a well-designed self-consumption system toward the three-to-four-year range. Crucially, that payback *accelerates* every time an FCA or tariff adjustment is notified — the hike that hurts your neighbour barely touches you.

How to position yourself before the next hike

Three concrete, first-hand tips we give every client at Best Solar Company PK:

1. **Shift load into daylight.** Run the washing machine, iron, water pump and — where possible — your inverter AC between roughly 9am and 4pm. This is free and instantly raises your self-consumption ratio. 2. **Add storage only if your evenings are heavy.** A hybrid system with a 10kWh lithium battery runs around **PKR 1,400,000–1,700,000**. It lets you self-consume after sunset instead of exporting cheaply at Rs8.13 — increasingly sensible under net billing. 3. **Right-size, don't oversize.** Because export now pays so little, a system matched to your daytime demand pays back faster than an oversized one built to sell surplus.

Frequently Asked Questions

**What is the Rs2.56 FCA on my November 2026 electricity bill?** It is the projected fuel cost adjustment for electricity generated in September 2026 — the gap between reference and actual fuel costs, mostly driven by expensive furnace oil and diesel. NEPRA hears the request on 29 October 2026, and the charge is expected to add about Rs32.7 billion across all consumers.

**Does the fuel cost adjustment apply to solar units I generate myself?** No. The FCA applies only to units imported from the grid. Electricity your rooftop system produces and you consume on the spot carries no FCA, no base tariff, and no surcharges — which is precisely why each hike widens solar savings.

**Is net metering still available in Pakistan in 2026?** For new applicants, NEPRA has moved to net billing under the Prosumer Regulations 2026, with a buyback rate near Rs8.13 per unit. Consumers who signed a net-metering agreement before 9 February 2026 are grandfathered at the older rate (around Rs25.32) until their contract expires.

**Should I still export surplus solar power under net billing?** Self-consumption is now far more valuable than export. Since exported units earn only about Rs8.13, you save much more by using your own generation to avoid grid units priced at Rs55–65+. Battery storage helps you self-consume in the evening instead of exporting cheaply.

The bottom line

The Rs2.56 September FCA — stacked on October's Rs1.11 — is a reminder that grid electricity in Pakistan is on a one-way escalator. Each adjustment transfers more cost onto the meter. Solar self-consumption is the one lever ordinary households and businesses control: the more the grid tariff climbs, the more every self-generated unit is worth, and the faster a well-sized system pays for itself.
