Pakistan's power sector has reached a strange turning point. In August 2026, the country's distribution companies (DISCOs) went before NEPRA and asked to recover **Rs33.8 billion** from consumers through a quarterly tariff adjustment — and part of their explanation was blunt: solarisation is cutting grid sales, so those still on the grid must pay more.

If you are a homeowner or business owner weighing rooftop solar, this **solarisation tariff adjustment** is the clearest signal yet that the maths has permanently shifted. The grid is shrinking, its fixed costs are not, and every unit you keep buying from the wires is carrying a heavier and heavier burden.

What the Rs33.8bn quarterly tariff adjustment actually covers

The Rs33.778 billion request relates to the second quarter of FY26 (April–June 2026) and was heard by NEPRA in a public hearing on 12–13 August 2026. According to filings reported by Business Recorder and The Express Tribune, the amount was revised up from an initial Rs23 billion.

The breakdown tells the real story:

  • **Capacity charges: ~Rs46.3 billion** — payments owed to power plants whether or not their electricity is used.
  • **Variable O&M: Rs4.9 billion** — operation and maintenance costs.
  • **Negative adjustment: –Rs13.5 billion** — a credit for Use of System Charges and Market Operator Fee.

The likely per-unit hit is around **Rs1.34/kWh**, though some slabs could see bills rise by up to Rs4 per unit once passed through. Crucially, capacity payments — the biggest line item — are fixed. They don't fall when sales fall. That is the heart of the spiral.

Why DISCOs are blaming solarisation

At the hearing, distribution companies were unusually candid about *why* their sales are dropping. Their testimony, summarised by The News, painted a picture of a grid losing its best-paying customers:

  • **PESCO** reported roughly a **5% decline** in consumption, driven by domestic and commercial users.
  • **FESCO** saw domestic sales fall about **5%**, even as industrial demand rose 2%.
  • **MEPCO** said **nearly half its agricultural tubewells in Punjab** had switched to solar.
  • **QESCO** noted Balochistan's tubewells had largely **shifted to solar**.

DISCOs even admitted to imposing nighttime load-shedding in some areas because they "cannot economically sell expensive grid electricity at existing tariffs." When the people who leave are the ones who paid the most, the fixed costs get spread across a smaller pool — and each remaining bill climbs.

The grid's fixed costs stay flat while its customer base shrinks — so the fewer people left on the wires end up subsidising a system that everyone is quietly leaving.

The shrinking-grid cost spiral, explained

This is the mechanism every Pakistani electricity user should understand in 2026:

1. Rising tariffs and capacity payments push bills higher. 2. Households and businesses install solar to escape those bills. 3. Grid sales fall, but fixed capacity costs don't. 4. NEPRA approves adjustments like this Rs33.8bn one to recover the shortfall. 5. Remaining grid users pay even more — which pushes the *next* wave to go solar.

Each turn of the wheel makes the grid more expensive and solar more attractive. It is a self-reinforcing loop, and the Rs33.8bn adjustment is one visible turn of it. For a deeper look at how base rates are moving, see our guide on rising electricity tariffs in Pakistan.

What this means for the price you pay

Consider a mid-sized Lahore household using about 800 units a month. A Rs1.34/kWh adjustment adds roughly **Rs1,072** to a single month's bill — and quarterly adjustments recur. Layered on top of base tariffs, fuel charges and taxes, an average grid unit for a protected-slab-exceeding home can land well above **Rs60–70/kWh** all-in.

| Factor | Direction in 2026 | Effect on you | |---|---|---| | Capacity payments | Rising | Higher fixed cost per unit | | Grid sales volume | Falling (solarisation) | Costs spread over fewer users | | Quarterly tariff adjustments | Recurring (e.g. Rs33.8bn) | Periodic bill spikes | | Solar hardware prices (PKR) | Falling | Faster payback | | Net-metering buyback rate | Cut to Rs8.13/unit | Lower export value for new users |

Solar panel prices in Pakistan have fallen sharply — good-quality panels now sit around **Rs30–38 per watt**, and a 10kW system commonly costs **Rs1.6–2.2 million** installed. As grid units get more expensive and hardware gets cheaper, payback periods for a self-consumption-focused system have compressed to roughly **3–4 years** for many users.

The net-billing catch you must plan around

There is an important wrinkle. Under the **NEPRA (Prosumer) Regulations 2026**, effective 9 February 2026, new rooftop consumers moved from net metering to **net billing**. The buyback rate for exported units was slashed to **Rs8.13 per unit** — down from Rs25.32 — while imported units are charged at the full slab tariff.

Existing net-metering consumers keep their old Rs25.32/unit rate until their agreement expires, and the contract term for new connections dropped from 7 to 5 years. The practical lesson: the new economics reward **self-consumption**, not exporting surplus to the grid.

Frequently Asked Questions

**What is the Rs33.8bn solarisation tariff adjustment?** It is a quarterly tariff adjustment for Q2 FY26 that DISCOs asked NEPRA to approve in August 2026 to recover Rs33.778 billion, mostly capacity payments. DISCOs partly attributed the shortfall to solarisation reducing grid electricity sales.

**Will my electricity bill go up because of it?** Most likely yes. The estimated impact is around Rs1.34 per unit, though some consumer categories could see larger increases once the adjustment is passed through in monthly bills.

**Does going solar make the problem worse for others?** Individually, going solar lowers your own bill. Collectively, as more users leave the grid, fixed costs are spread across fewer people — which is the "shrinking-grid spiral" DISCOs are describing. Policy reform, not individual choice, is the real fix.

**Is solar still worth it after the net-billing change in 2026?** Yes, for most users — provided you design for self-consumption. With grid units getting more expensive and panel prices in PKR falling, payback often lands around 3–4 years, even at the lower Rs8.13/unit buyback rate.

The bottom line for Pakistani energy users

The Rs33.8bn adjustment is more than a line on your bill — it is proof that the cost of staying fully grid-dependent is rising structurally, not just seasonally. DISCOs have effectively confirmed that the grid is getting pricier for everyone left on it.

For homeowners and businesses, the rational response is to reduce exposure: pair a right-sized solar system with smart daytime usage, and treat the grid as a backup rather than your primary supply. The spiral will keep turning. The question is which side of it you want to be on.
