On 30 July 2026, the government signalled it is preparing a **new power tariff package** to respond to falling electricity demand—while simultaneously pushing a **Rs1.20 per unit Fuel Cost Adjustment (FCA) hike** onto August bills. If that sounds contradictory, it is. Demand is dropping, yet the price per unit keeps climbing. For Pakistani homeowners and businesses, this new power tariff package is the clearest signal yet that grid electricity is only getting more expensive—and that rooftop solar now pays for itself faster than most people realise.

At Best Solar Company PK, we track every NEPRA notification because these numbers directly change your payback maths. Here is what the July 30 developments mean for your bill, and why the "shrinking-base loop" is quietly working in favour of anyone who switches to solar.

What the July 30 tariff news actually says

The Central Power Purchasing Agency (CPPA) has asked NEPRA to approve an additional **Rs1.20 per unit** under the June 2026 fuel price adjustment. The reason is a fuel-cost gap: the reference fuel cost for June was set at **Rs7.714 per unit**, but actual generation cost came in at **Rs8.90 per unit**. That gap is now being recovered from consumers—roughly **Rs15.7 billion** collected through August electricity bills.

The net sting is slightly smaller than Rs1.20. An existing FCA of about **34 paisa per unit** is expiring, so most consumers will feel a **net increase of around 86 paisa per unit** in August, pending NEPRA's final determination after its public hearing.

Separately, the government hinted at a broader **new power tariff package** because electricity demand is sliding. In June 2026, national power sales fell **3.3% year-on-year**—to **9.995 billion units** from **10.337 billion units** in June 2025.

When fewer units are sold but the same fixed capacity and debt must be paid for, the cost per unit has to rise. That is the shrinking-base loop—and it is structural, not temporary.

The shrinking-base loop, explained simply

Pakistan's power sector carries huge **fixed costs**: capacity payments to independent power producers (IPPs), circular debt, transmission losses, and currency-linked fuel bills. These costs stay roughly the same whether the country consumes 10 billion units or 9 billion units.

So when demand drops—because industry slows, or because more households install solar—the same mountain of fixed cost is spread over **fewer billed units**. Per-unit tariffs rise to cover the gap. Higher tariffs push even more consumers to conserve or go solar. Demand falls further. Tariffs rise again.

Here is the loop in plain terms:

  • Fixed costs stay high → per-unit price must rise.
  • Higher bills → consumers cut usage or install solar.
  • Fewer units sold → the base shrinks.
  • Shrinking base → per-unit price rises **again**.

For grid-dependent consumers, this is a trap. For solar owners, it is an accelerant: every FCA hike and every tariff package makes the electricity you *avoid buying* more valuable.

What this means for your monthly bill

Consider a typical household consuming **600 units a month**. An 86-paisa net FCA increase adds roughly **Rs516** to the August bill—before General Sales Tax and other surcharges, which push the real impact higher. For a small business or factory drawing **5,000 units**, the same adjustment adds around **Rs4,300 a month** on the FCA line alone.

And remember: FCA is *just one line item*. It stacks on top of base tariffs, quarterly tariff adjustments, fixed charges, and taxes. The new power tariff package under discussion could reset several of these lines at once.

| Monthly usage | ~86 paisa/unit FCA impact | Rough added cost/month | |---|---|---| | 300 units (small home) | 300 × 0.86 | ~Rs258 | | 600 units (mid home) | 600 × 0.86 | ~Rs516 | | 1,200 units (large home) | 1,200 × 0.86 | ~Rs1,032 | | 5,000 units (SME) | 5,000 × 0.86 | ~Rs4,300 |

These are FCA-only figures; your full bill increase will be larger once taxes and other adjustments apply.

Why solar pays back faster in this environment

The single biggest driver of solar payback is the **grid tariff you offset**. When you self-consume solar power during the day, every unit you don't buy from the grid saves you the *full* retail rate—base tariff **plus** FCA, **plus** taxes and surcharges. As tariffs climb, each solar unit saves you more rupees than it did last year.

A well-designed **on-grid solar system** in 2026 typically costs between **Rs120,000 and Rs160,000 per kW** installed (panels, inverter, mounting, net-metering paperwork), depending on brand and location. For a 10 kW residential system:

  • Approximate cost: **Rs1.2–1.6 million**
  • Typical daytime self-consumption savings + export: **Rs45,000–70,000 per month** for a high-usage home or shop
  • Payback: commonly **2.5 to 4 years**, then 20+ years of near-free daytime power

Every tariff hike shortens that payback window. A system that looked like a 4-year payback at last year's rates can slip under 3 years after a couple of FCA increases and a new tariff package.

Net billing changed the maths—here's the honest version

Be aware of one important 2026 change. Since **9 February 2026**, NEPRA replaced classic **net metering** with a **net billing** model for *new* solar connections. Under net billing, surplus units you export are bought back at a lower rate—around **Rs11–13 per unit** (down from the old **Rs25.32 per unit** that existing consumers still enjoy). New connections also face a **five-year buyback contract** and a licensing fee of about **Rs1,000 per kW**.

The practical takeaway: **self-consumption now matters more than export.** The smartest 2026 systems are sized so you *use* most of your solar during daylight—running ACs, pumps, and machinery on the sun—rather than exporting cheaply. Our engineers design around your daytime load curve to maximise savings under the new rules. Read our full breakdown in net metering vs net billing in Pakistan.

The practical move for 2026

The July 30 signals confirm a trend that has held for years: **grid electricity in Pakistan gets more expensive, not less.** You cannot control NEPRA, the rupee, or global fuel prices. You *can* control how many units you buy from the grid.

Our first-hand experience across hundreds of installations in Lahore, Karachi, and Islamabad is consistent: customers who went solar in 2023–2024 are now insulated from exactly the FCA hikes and tariff packages making 2026 headlines. Their neighbours are absorbing every increase.

Frequently Asked Questions

**What is the Rs1.20 FCA hike and when does it apply?** It is an additional Fuel Cost Adjustment of Rs1.20 per unit requested for the June 2026 fuel adjustment, recovered through August bills pending NEPRA approval. Because an existing 34-paisa FCA is expiring, most consumers will see a net increase of about 86 paisa per unit.

**Why are tariffs rising even though electricity demand fell 3.3%?** Pakistan's power sector has large fixed costs—capacity payments, circular debt, and fuel bills—that must be paid regardless of how many units are sold. When demand shrinks, those costs spread over fewer units, so the per-unit price rises. That's the shrinking-base loop.

**Does the new power tariff package make solar a better investment?** Yes. Every increase in the grid tariff raises the value of each unit your solar system offsets. Higher bills shorten the payback period, which in 2026 is commonly 2.5–4 years for a well-sized on-grid system.

**How does net billing affect my savings compared to old net metering?** Under net billing (effective February 2026), exported surplus is bought back at a lower rate—around Rs11–13 per unit—so the best strategy is to size your system for daytime self-consumption rather than large exports. Existing net-metering consumers keep their older, higher buyback rate.

The bottom line

The new power tariff package and the Rs1.20 FCA hike are not one-off events—they are the predictable output of a shrinking-base loop that keeps grid electricity climbing in 2026.
