If you installed solar expecting your electricity bill to drop to zero, 2026 has brought a hard reality check. The **NEPRA fixed network charges** rolled out this year mean that even a home producing all its own power will still receive a monthly bill from its DISCO. Understanding why this happened—and how to plan around it—is now essential before you spend a single rupee on panels.

This isn't a glitch or a temporary surcharge. It is a deliberate structural shift in how Pakistan prices electricity, driven in large part by the very rooftop solar boom you may be part of.

What Changed: From Per-Unit Billing to Fixed Charges

For decades, your electricity bill in Pakistan was almost entirely *volumetric*—you paid per unit (kWh) consumed. Use less, pay less. Solar fit perfectly into that model: generate your own units, slash your bill.

In February 2026, NEPRA (the National Electric Power Regulatory Authority) approved a broad tariff rationalisation for ex-WAPDA DISCOs and K-Electric. It introduced **fixed monthly charges ranging from Rs200 to Rs675 per kW**, applied regardless of how many units you consume. Crucially, the charge is levied *per kilowatt of sanctioned load*—not a flat per-connection fee—so a home with a bigger load pays more.

Here is how the fixed charges break down by consumer category:

| Consumer type | Monthly usage (units) | Fixed charge (Rs/kW/month) | |---|---|---| | Protected | 1–100 | 200 | | Protected | 101–200 | 300 | | Non-protected | 1–100 | 275 | | Non-protected | 101–200 | 300 | | Non-protected | 201–300 | 350 | | Non-protected | 301–400 | 400 | | Non-protected | 401–500 | 500 | | Non-protected | 501–600 | 675 |

Lifeline consumers are exempt. But for the roughly 28.5 million households above that threshold, a fixed line item now appears on every bill—whether you draw grid power or not.

Why Rooftop Solar Triggered the Shift

Here is the part most installers won't tell you: your solar panels helped cause this.

As rooftop solar penetration exploded—Pakistan imported record volumes of panels through 2024 and 2025—grid-based electricity demand started falling. The problem is that the national grid's biggest costs are *fixed*: transmission lines, distribution infrastructure, transformers, and capacity payments to power plants. Those costs don't disappear when you generate your own power.

When solar users stop buying units, the grid's fixed costs get spread across fewer units—pushing per-unit prices up for everyone and creating a "death spiral" the regulator is now trying to break.

NEPRA has openly stated it needs to "gradually move away from the volumetric nature of tariff towards a more fixed cost-oriented tariff structure." In plainer terms: the grid wants to recover its infrastructure costs from a fixed charge tied to your connection, so that solar adoption doesn't keep eroding its revenue base. A power-sector reform committee has been empowering the regulator to accelerate exactly this restructuring through 2026.

The Double Hit: Net Billing Replaced Net Metering

Fixed charges aren't the only change squeezing solar economics. In the same wave of 2026 reforms, NEPRA **replaced net metering with net billing** for new prosumers.

Under the old net metering, one unit you exported offset one unit you imported—a clean one-for-one swap. Under the new net billing model, that swap is gone:

  • Units you **export** are bought back at a low, separately-set rate—roughly **Rs8–11 per unit** (NEPRA figures around Rs8.13, with some notifications near Rs9.80).
  • Units you **import** from the grid are still billed at the full retail tariff, which can exceed Rs40–60/unit with taxes.
  • The prosumer contract term was cut from **seven years to five years**.

So you now sell cheap and buy expensive—plus you pay a fixed charge on top. That combination is precisely why your bill won't hit zero.

Why Your Bill Won't Reach Zero—A Worked Example

Consider a non-protected household in Lahore with a 5 kW sanctioned load, consuming around 450 units a month before solar.

  • **Fixed charge:** at the 401–500 unit slab (Rs500/kW), that's 5 × Rs500 = **Rs2,500/month**, owed even in a month when the panels cover every single unit.
  • **Export income:** surplus units sold back earn only ~Rs8–11 each, far below what you'd save by self-consuming them.
  • **Imports:** any evening or cloudy-day grid draw is billed at the full retail rate.

The practical takeaway: a well-sized system can still cut your bill by 60–80%, but that last stretch to zero is now blocked by design.

How to Plan Your Solar Investment Around the New Rules

The reforms change the math, but solar is still strongly worth it in Pakistan—you just need to optimise differently. Based on what's working for homeowners under the 2026 regime:

1. **Size for self-consumption, not export.** Since exports earn only Rs8–11/unit, every unit you *use yourself* is worth far more. Right-size the system to your daytime load rather than overbuilding to sell surplus. 2. **Add battery storage.** Storing midday solar to use in the evening lets you avoid buying grid units at Rs40–60—a far better return than exporting at Rs9. Batteries have shifted from luxury to core economics. 3. **Review your sanctioned load.** Because fixed charges are per kW of load, an unnecessarily high sanctioned load inflates your fixed bill. Ask your DISCO whether your load can be rationalised. 4. **Lock in existing agreements.** If you already have a net-metering agreement, you are **grandfathered**—your old one-for-one terms and buyback rate continue for the life of your contract. Don't cancel it. 5. **Act before terms tighten further.** PM Shehbaz Sharif stepped in to review the solar rules after public backlash, signalling the framework is still moving. Current five-year net-billing terms may not last.

Frequently Asked Questions

**Will the NEPRA fixed network charges apply to me if my solar covers 100% of my usage?**

Yes. The fixed charge is tied to your sanctioned load and grid connection, not your consumption. Even in a month where your panels supply every unit, you'll still owe the per-kW fixed charge—this is the single biggest reason your bill won't reach zero.

**Are existing net-metering users affected by the switch to net billing?**

No. Existing consumers are grandfathered. If your net-metering agreement with your DISCO was already signed, your previous one-for-one terms and older buyback rate continue for the full duration of your contract. The new net-billing rules apply to new applications.

**How much is the new solar buyback rate in 2026?**

NEPRA has set the export buyback rate for new prosumers at roughly Rs8–11 per unit (official figures cite around Rs8.13, with some notifications near Rs9.80)—down sharply from the earlier Rs19–27 per unit. This makes self-consumption and battery storage far more valuable than exporting surplus.

**Is rooftop solar still worth it in Pakistan after these changes?**

Absolutely—but the strategy has changed. With retail tariffs still high, a system sized for self-consumption (ideally with a battery) can cut your bill by 60–80%. You simply shouldn't expect a zero bill or rely on export income the way earlier adopters did.

The Bottom Line

The shift to **NEPRA fixed network charges** marks the end of the "zero-bill" era for rooftop solar in Pakistan. The regulator is restructuring tariffs precisely because solar is working—so well that it's reshaping grid economics. For homeowners and businesses, the opportunity is still real; it just rewards smart sizing, storage, and self-consumption over chasing exports.
