If your power bill already feels heavier, brace yourself: another **fuel charge adjustment (FCA) hike** is on the way. The Central Power Purchasing Agency-Guaranteed (CPPA-G) has asked NEPRA to approve a **sixth consecutive** monthly FCA increase — **Rs2.56 per unit** for September — on top of the **Rs1.11 per unit** already notified for October bills. For a country sitting on surplus generation capacity, that is a hard pill to swallow.

This fuel charge adjustment hike is not a one-off. Since April 2026, consumers have paid over Rs140 billion extra in monthly FCAs. Below, we break down what the Rs2.56 request means in rupees, why your bill keeps rising despite the surplus, and — most importantly — how rooftop solar caps your exposure to this endless fuel-cost rollercoaster.

What the sixth FCA hike actually means

CPPA-G's application tells the story in numbers. The reference fuel cost for September was pegged at **Rs7.46 per unit**, but the *actual* cost climbed to **Rs10.02 per unit** — a gap of Rs2.56 that the agency now wants to recover from consumers. Total fuel cost of generation for the month hit **Rs127.87 billion**.

NEPRA has scheduled a public hearing on **October 29, 2026** to decide the request. If approved, the charge will likely land on **November bills**. You can track the official docket on the <a href="https://nepra.org.pk" target="_blank" rel="noopener">NEPRA</a> website.

Here is how the recent FCAs stack up on a typical household:

| Adjustment | Rate | Billing month | Monthly cost on 600 units | |---|---|---|---| | August FCA (notified) | Rs1.11/unit | October 2026 | Rs666 | | September FCA (requested) | Rs2.56/unit | November 2026 (if approved) | Rs1,536 | | Combined exposure | Rs3.67/unit | Oct–Nov | Rs2,202 |

For a 600-unit home, that is over **Rs2,200 in pure fuel surcharges** across two months — before GST, TV fee, and other line items pile on. A small shop or clinic running 1,500 units would see roughly Rs5,500 added.

The FCA is a pass-through: whatever it costs to burn fuel that month, you pay — win, lose, or draw. Your own consumption habits don't change it.

Note: the Rs1.11 October FCA applies to all categories of the ex-WAPDA DISCOs and K-Electric **except** lifeline consumers, EV charging stations, and prepaid-tariff users.

Why bills keep climbing despite a power surplus

Here is the paradox many Pakistani homeowners ask about: the country has *more* installed capacity than it needs, so why do bills keep rising?

  • **Fuel mix, not fuel shortage.** September generation leaned heavily on expensive imported fuel — imported coal cost Rs37.14 billion and LNG Rs31.93 billion for the month. When pricey imported fuel runs, the FCA rises regardless of surplus.
  • **Rupee and commodity swings.** FCAs track international fuel prices and the exchange rate. A weaker rupee inflates every imported-fuel invoice.
  • **Capacity payments are separate.** The surplus actually *adds* fixed capacity charges to the base tariff — a different problem from the FCA, but it's why "surplus" never translates into cheaper bills.
  • **Transmission and seasonal demand.** Lower hydel output in dry months pushes the grid toward thermal plants, raising the fuel component.

In short, surplus capacity does nothing to shield you from fuel-cost volatility. The only way to stop paying a per-unit fuel charge is to **buy fewer units from the grid**.

How solar caps your fuel-charge exposure

This is the practical takeaway. Every unit you generate on your own roof is a unit the grid never bills you for — and a unit that carries **zero FCA**. Solar doesn't just lower your base tariff; it directly shrinks the denominator the fuel charge is multiplied against.

Consider a household consuming 1,000 units a month. Install a well-sized system that offsets 650 of those units, and the Rs3.67/unit combined FCA now applies to ~350 grid units instead of 1,000 — cutting that surcharge line from roughly Rs3,670 to Rs1,285.

Current installed prices make the math compelling. As of October 2026:

  • **On-grid systems:** about **Rs95–130 per watt** installed
  • **Hybrid (with battery):** about **Rs140–180 per watt**
  • **A-grade panels:** roughly **Rs39–43 per watt** at the module level

That puts a **5kW on-grid system around Rs475,000–650,000**, and a **10kW system around Rs950,000–1,300,000**. With grid tariffs plus FCAs now routinely above Rs50–60 per unit for mid-slab users, most homes recover that investment in **3–4 years** and enjoy 20+ years of near-free daytime power.

What changed under net billing in 2026 — does solar still pay?

Yes — but the rules shifted, so size your system smartly. In 2026 NEPRA replaced **net metering** with **net billing** under the Prosumer Regulations. Key changes:

  • **Buyback rate dropped** to around **Rs11 per unit** (pegged to the National Average Energy Purchase Price), down from the old ~Rs25.9/unit.
  • **Imported and exported units are no longer swapped one-for-one** — you buy at full tariff, sell surplus at the lower buyback rate.
  • **Contract term cut** from seven to **five years**.
  • **Existing users are grandfathered:** if you signed a valid net-metering agreement **before 9 February 2026**, you keep your old terms until it expires.

The lesson: under net billing, **self-consumption is king**. Design the system to match your daytime load (or add a battery) rather than oversizing to export cheaply.

Frequently Asked Questions

**What is the fuel charge adjustment (FCA) and why is CPPA-G asking for Rs2.56 per unit?** The FCA is a monthly pass-through that reconciles the reference fuel cost with the actual cost of generating electricity. For September, actual cost rose to Rs10.02/unit against a reference of Rs7.46/unit, so CPPA-G is seeking Rs2.56/unit to recover the difference.

**When will the Rs2.56 FCA hit my bill?** NEPRA holds a public hearing on October 29, 2026. If approved, the charge will most likely appear in November bills, stacking on the Rs1.11/unit August FCA already applied to October bills.

**Why do bills rise when Pakistan has surplus electricity?** Surplus capacity controls availability, not fuel cost. The FCA reflects expensive imported coal and LNG and rupee movements — so bills climb on fuel economics even when plenty of capacity sits idle. The surplus also adds capacity charges to the base tariff.

**Does solar still make financial sense after the shift to net billing?** Absolutely — especially for self-consumption. Every unit you produce avoids both the base tariff and the FCA entirely. With payback typically 3–4 years at current tariffs and prices, solar remains one of the best hedges against endless fuel surcharges.

The bottom line

Six FCA hikes in a row prove a simple truth: as long as you depend on the grid, you ride every swing in global fuel prices and the rupee. A right-sized rooftop solar system is the one move that permanently caps your fuel-charge exposure — slashing the units the FCA can touch. With panel prices at multi-year lows in 2026, there has rarely been a better time to lock in your own power. **Get a free bill audit and custom quote from Best Solar Company PK today.**
