Pakistan's power sector is entering a strange new phase. After years of crippling bills that pushed thousands of factories and homes to rooftops, the grid now has a daytime surplus — and the government wants industry to buy it cheap. The proposed **Rs6 per unit daytime power** package is the headline of a broader time-of-use (ToU) shift, and it could quietly change how you calculate commercial solar and battery ROI in 2026.

If you run a factory, warehouse, cold storage, or a mid-size commercial building, this is a policy you cannot afford to ignore. Cheap daytime grid electricity attacks the exact hours when your solar panels produce the most. Let's break down what's actually on the table, what it means for your payback period, and how to protect your investment.

What the Rs6 Daytime Power Package Actually Proposes

The Ministry of Energy is working on a time-of-use tariff for the industrial sector designed to soak up surplus daytime generation. Under the proposal, eligible industrial consumers would pay roughly:

  • **Rs6 per unit during daytime hours** (plus fixed charges)
  • **Rs10 per unit during night hours** (plus fixed charges)

Compare that to today. Industry currently pays around **Rs30 per unit** (excluding fixed charges), making electricity one of the single biggest drags on manufacturing competitiveness in Pakistan. A drop to Rs6 in daylight is not a tweak — it's a five-fold cut.

A grid that once punished daytime usage now wants to reward it. That single reversal is what changes the solar math.

There's a catch, and it's a big one. As of August 2026, Power Minister Awais Leghari has confirmed that the marginal ~Rs6/kWh daytime tariff is **not yet being allowed**, with restrictions tied to Pakistan's IMF programme cited as the blocker. So treat Rs6 as a *proposed* signal of direction, not a rate you can bank on tomorrow. Read the fine print before you rebuild your energy strategy around it.

Why the Grid Suddenly Has Cheap Daytime Power

This surplus didn't appear by accident. Pakistan has seen an extraordinary solar surge — driven by imported panels, high tariffs, and businesses fleeing the grid. So much distributed solar now floods the system during peak sun that daytime demand on the national grid has softened.

The country is also targeting roughly **90% clean energy by 2035**, according to statements from the Power Division. The government's problem has shifted from *generating* enough power to *managing* when it's used and *storing* it. Cheap daytime tariffs are a demand-side tool: shift industrial load into sunny hours, flatten the curve, and reduce curtailment.

For solar owners, that's the twist. The very success of rooftop solar is what created the surplus now being offered back at Rs6.

The Impact on Commercial Solar ROI

Here's the honest part. If a factory can buy grid power at Rs6 during the day, the *savings* from a daytime solar system shrink, because you're now displacing cheap electricity instead of Rs30 electricity.

Consider a simplified commercial example:

| Scenario | Grid daytime rate | Value of 1 solar unit (self-consumed) | |---|---|---| | Today (2026) | ~Rs30/unit | ~Rs30 saved | | Proposed Rs6 ToU | ~Rs6/unit | ~Rs6 saved |

A 100 kW commercial system generating ~400 units on a good day would save around Rs12,000 daily at Rs30 — but only ~Rs2,400 daily if daytime grid power falls to Rs6. On paper, that stretches a 3–4 year payback toward 8–10 years for daytime self-consumption alone.

But that's not the full story, and this is the original insight most vendors won't tell you:

  • The Rs6 rate is **not guaranteed** and applies to **industry**, not most commercial or domestic tariffs.
  • Night power stays at **Rs10+**, and fixed charges remain.
  • Under NEPRA's new **net billing** regime, exporting solar is now poorly rewarded (more below).
  • Solar still hedges you against **future tariff hikes, fuel cost adjustments, and load-shedding** — risks that don't vanish.

Net Billing Changes the Calculation Too

You can't read the ToU proposal without reading it alongside NEPRA's **Prosumer Regulations 2026**, notified on 9 February 2026. These scrapped the old 2015 net-metering framework and replaced it with **net billing**.

Key changes:

  • New solar connections get a **buyback rate of roughly Rs11 per unit** for exported power (earlier reductions targeted as low as Rs8.13).
  • **Existing** net-metering consumers continue at the older ~**Rs25.32 per unit** for their remaining term.
  • Contract periods for new installations were cut from 7 years to **5 years**.
  • Imported units are billed at full slab tariffs; exported units no longer offset imports one-to-one.

The message is unmistakable: **exporting to the grid is out; self-consumption and storage are in.** For a full breakdown, see our guide on NEPRA's shift from net metering to net billing.

Where Batteries Win — and Where They Don't

This is where the ToU package flips from threat to opportunity — *if* you get the design right.

A ToU spread between Rs6 daytime and Rs10+ nighttime creates an **arbitrage window**. The classic battery play is: store cheap or free energy by day, discharge it at night to dodge the higher rate.

But do the arithmetic before you buy:

  • Lithium batteries in Pakistan cost roughly **Rs40,000–55,000 per kWh** installed.
  • The Rs6-to-Rs10 spread is only about **Rs4 per unit** — thin margin for arbitrage on grid power alone.
  • Charging a battery from **your own solar** (near-zero marginal cost) and discharging at night against Rs10+ is where the real return sits.

Batteries make sense when they let you *avoid* expensive night power using free solar — not when you're speculating on a Rs4 grid spread.

For most factories, the smart 2026 configuration is a **hybrid solar system sized for daytime self-consumption**, plus **modest battery storage** to shift surplus into the evening peak. Oversizing for export no longer pays under net billing. Explore sizing options in our commercial solar system buyer's guide.

A Practical Playbook for 2026

Based on the current policy signals, here's how we'd advise a commercial client today:

1. **Don't over-invest in export capacity.** Net billing has killed the export windfall. 2. **Size solar to your daytime load** so nearly every unit is self-consumed. 3. **Add storage strategically** to beat Rs10+ night rates, not to chase grid arbitrage. 4. **Track the ToU rollout.** If Rs6 daytime becomes real for your tariff category, revisit your load schedule — you may run heavy machinery on cheap grid power and save the battery for nights. 5. **Lock in favourable terms early** where existing-consumer rates still apply.

Frequently Asked Questions

**Is the Rs6 per unit daytime tariff available now in Pakistan?** Not yet. As of August 2026 it remains a proposal for the industrial sector, and officials have said IMF programme conditions are currently blocking implementation of the marginal ~Rs6/kWh daytime rate. Confirm your exact tariff category with your DISCO before planning around it.

**Does cheap daytime grid power make commercial solar a bad investment?** No, but it changes the math. Lower daytime rates reduce the savings from self-consumed solar, stretching payback. Solar still hedges against tariff hikes, load-shedding, and rising night rates — and pairs well with storage. Just avoid oversizing for export.

**What is the new solar buyback rate under net billing?** New connections after NEPRA's 9 February 2026 Prosumer Regulations receive roughly Rs11 per unit for exported electricity, down sharply from the past. Existing net-metering users keep their older ~Rs25.32 per unit for the remainder of their term.

**Should I add a battery because of the time-of-use tariff?** Only if the numbers work. Storing free daytime solar to offset Rs10+ night power is the strongest case. Pure grid arbitrage on the narrow Rs6-to-Rs10 spread rarely justifies today's Rs40,000–55,000 per kWh lithium prices.

The Bottom Line

The proposed **Rs6 daytime power** package is a signal that Pakistan's energy story has moved from scarcity to timing. Cheap grid daylight will compress the savings from daytime-only solar, and net billing has already ended the export gold rush. But solar-plus-storage, sized for self-consumption and evening peaks, remains a strong, inflation-proof play for Pakistani industry in 2026.

The winners won't be those who install the biggest system — they'll be those who match generation, storage, and load to the new tariff clock.
