Every winter, Pakistani households face the same question in a new form. This year it comes down to one decision: with the **winter incremental consumption package** offering cheap "extra units" from the grid, should solar homes simply lean on WAPDA this season — or double down on self-consumption and battery backup instead?

On **October 5, 2026**, NEPRA will hold a public hearing to review the Prime Minister's Incremental Consumption Package. The outcome will shape how much that "cheap extra unit" actually costs you between December and February — and it lands at the exact moment solar economics in Pakistan have been turned upside down by the shift to net billing.

Let's break down the real numbers so you can plan before your first high winter bill arrives.

What the winter incremental consumption package actually is

The incremental consumption package is simple in principle: use *more* electricity than a defined baseline, and the extra units are billed at a flat, discounted rate instead of the painful top slab.

  • Last winter (Dec 2024–Feb 2025), domestic consumers paid a flat **Rs26.07 per unit** on incremental usage above a threshold — a saving of roughly **Rs11 to Rs26 per unit** versus normal slab rates.
  • The parallel industrial and agricultural package set additional units at a flat **Rs22.98 per unit**, down from Rs34 (industry) and Rs38 (agriculture).
  • The idea is to soak up Pakistan's surplus winter generation capacity instead of letting expensive idle plants sit on consumers' bills as capacity payments.

So for a brief window, grid power becomes genuinely cheap — sometimes cheaper than what you'd pay to store your own solar in a battery.

Why October 5 matters for your winter bill

The NEPRA hearing isn't a routine rubber stamp. The regulator has framed three pointed questions:

1. Should the package be **temporarily suspended** given current fuel prices? 2. Should the Rs22.98/unit rate be **revised upward** to match the actual marginal cost of generation? 3. If revised, should it apply from June 2026, October 2026, or another date?

If NEPRA lifts the incremental rate toward the true marginal cost, the "cheap unit" advantage shrinks — and the case for your own stored solar gets stronger overnight.

With consumers already facing roughly **Rs25 billion in additional fuel-cost adjustments**, the direction of travel is upward. Treat this winter's cheap-grid window as temporary, not guaranteed.

The net-billing twist every solar home must understand

Here is what changes the whole calculation. On **February 9, 2026**, NEPRA notified the Prosumer Regulations 2026, ending classic net metering for new systems and moving to **net billing**.

  • New prosumers now export surplus solar at a buyback rate of only about **Rs10–11 per unit**, down from roughly **Rs25.9 per unit**.
  • You still *buy* grid power at the full tariff (often Rs40–60+ per unit on upper slabs), so imported and exported units are no longer a fair swap.
  • Contract terms shrank from 7 years to 5, and fixed monthly charges of **Rs200–675** now apply to domestic consumers.
  • Crucially, agreements signed **before** February 2026 are protected and keep their original net-metering terms.

That single change — exports worth Rs11 instead of Rs26 — is why "just export it" is no longer a winning strategy for new solar homes. For a deeper walkthrough, see our guide to net metering vs net billing in Pakistan.

Grid-lean vs self-consumption: the winter math

Winter is the hardest season for solar. Short days, Punjab fog, and low sun angles can cut panel output by 30–50% versus summer. So you naturally import more and export less exactly when the incremental package makes grid units cheap.

Here's how the three strategies compare for a typical home:

| Strategy | Effective cost of a winter "extra" unit | Best for | Key risk | |---|---|---|---| | Lean on grid (incremental package) | ~Rs23–26/unit | All homes, this winter only | Rate rises after Oct 5 review | | Export surplus solar (net billing) | You only *earn* ~Rs11/unit | Legacy net-metering homes | Poor value for new prosumers | | Self-consume + battery | ~Rs18–30/unit (storage cost) | Load-shedding areas, new prosumers | Upfront battery cost |

The honest takeaway:

  • **If you are a legacy net-metering customer (pre-Feb 2026):** your exports are still worth ~Rs26/unit, so keep exporting daytime surplus and lean lightly on the incremental package for evening heating.
  • **If you are a new net-billing prosumer:** exporting at Rs11 is almost giving power away. Prioritise **self-consumption** — run heavy loads (geysers, washing, iron) during daylight hours while your panels are producing.
  • **For everyone:** the cheap incremental grid rate makes winter the *worst* time to buy a battery purely for savings — but the *best* case for a battery is backup during fog-driven low-generation days and load-shedding, not arbitrage.

A practical winter plan for solar homes

Based on what we see with customers across Punjab and Sindh, here's a sensible approach for the Dec–Feb window:

1. **Shift timing, not just source.** Move high-wattage tasks to 10am–3pm so solar covers them directly — self-consumed units are worth your full avoided tariff. 2. **Use the incremental package for evening heat.** Space heaters and geysers after sunset are cheaper on the ~Rs23–26 incremental rate than draining a battery you paid Rs25+/unit to charge. 3. **Right-size batteries for backup, not bill-shaving.** A 5kWh lithium bank covers essential evening loads during fog days; don't oversize chasing marginal savings. 4. **Lock in legacy terms if you qualify.** If your agreement predates February 2026, protect it — don't modify your system in a way that forces a new net-billing contract. 5. **Watch the Oct 5 outcome.** If the rate is revised up, pivot harder toward self-consumption and consider expanding capacity in spring.

Frequently Asked Questions

**What is the winter incremental consumption package in Pakistan?** It's a seasonal relief measure where electricity used above a baseline threshold during winter months is billed at a flat discounted rate — around Rs26.07/unit for domestic users last winter — instead of expensive top-slab rates, to use surplus generation capacity.

**Will the incremental package rate change after the October 5, 2026 NEPRA hearing?** Possibly. NEPRA is reviewing whether to suspend the package or raise the Rs22.98/unit industrial-agricultural rate toward actual marginal cost. Any revision could flow into domestic rates, so treat this winter's cheap window as temporary.

**Should solar homes use grid power this winter instead of batteries?** For most homes, yes — selectively. The cheap incremental grid rate (~Rs23–26) is often cheaper than battery storage for evening heating, so use the grid for peak heat and keep batteries for backup during fog and load-shedding.

**Is net billing worse than net metering for winter savings?** For new prosumers, yes. Net billing pays only ~Rs11/unit for exports versus ~Rs26 under old net metering, so exporting surplus is poor value. Maximise daytime self-consumption instead of relying on export credits.

The bottom line

This winter is a bridge, not a destination. The **winter incremental consumption package** gives you a short, genuinely cheap window of grid power — use it smartly for evening heating. But the Rs11 net-billing buyback rate is the real signal: Pakistan is steadily pushing solar homes toward **self-consumption and backup storage**, not grid export.

Lean on the grid where it's cheap today, build toward energy independence for tomorrow, and watch the October 5 ruling closely. Want a winter-ready system or battery audit? Talk to our team for a free load and savings assessment.
