Net Billing Pakistan 2026 Guide — Complete Homeowner’s

If you have solar panels, are planning to get them, or simply received a confusing LESCO bill recently — net billing Pakistan 2026 is the policy change you need to understand. NEPRA officially replaced the old net metering system with net billing under the Prosumer Regulations 2026 (SRO 251(I)/2026). What changed, what stayed the same, and what it means practically for your home or business — this guide covers all of it clearly.

Quick Answer — What Is Net Billing in Pakistan?

Net metering (old system): Every unit you exported to the grid cancelled out one unit you imported. It was a 1:1 swap. If you exported 400 units and imported 400 units, your energy charge was essentially zero.

Net billing (new system): Exported units and imported units are now separate transactions with different rates. You sell your surplus at approximately Rs. 11 per unit. You buy from LESCO at Rs. 40 to 65 per unit depending on your slab. They are no longer offset against each other.

That gap — between what you sell and what you buy — is the entire story of net billing Pakistan 2026.

What Exactly Changed Under NEPRA Prosumer Regulations 2026?

NEPRA officially abolished the traditional net metering regime and replaced it with a new net billing system under the NEPRA Prosumer Regulations 2026. Here are the specific changes that affect every solar owner in Pakistan:

Export rate dropped sharply. Under Pakistan’s revised 2026 net billing framework, NEPRA links export compensation to the national average energy purchase price rather than the retail tariff. In practice this means approximately Rs. 10 to 13 per unit for exported electricity — compared to the retail rate of Rs. 40 to 65 per unit you previously received credit for. sciencedirect

Agreement period shortened. New net billing agreements run for 5 years. The old net metering agreements ran for 7 years.

Net Metering Regulations 2015 are repealed. With the implementation of the Net Metering Regulations 2026, the Net Metering Regulations 2015 are formally suspended. All billing, payments, and contracts going forward are governed under the new regulatory framework. samaa

Existing agreements are protected — for now. The new net billing rules apply only to new connections made after the policy cut-off date. Pre-February-2026 agreements keep their original terms. However, when those agreements expire, renewals fall under the new net billing framework

The Bill Calculation — Before and After for Net Billing Pakistan 2026 Guide

This is the number that hits hardest. Here is the same household under both systems:

Household example: Monthly import 600 units, monthly export 400 units, LESCO tariff Rs. 55 per unit

	Old Net Metering	New Net Billing 2026
Import units	600 units	600 units
Export units	400 units	400 units
Import cost	200 × Rs. 55 = Rs. 11,000	600 × Rs. 55 = Rs. 33,000
Export credit	(offset against import)	400 × Rs. 11 = Rs. 4,400
Final bill	Rs. 11,000	Rs. 28,600
Difference	—	Rs. 17,600 more per month

This is why net billing Pakistan 2026 felt like a shock. The same solar system, the same export amount, the same import amount — but a bill almost three times higher.

The important point: this gap only hits you on the units you export. Every unit you consume directly from solar still saves you the full Rs. 55. The problem is purely the exported surplus.

Who Is Affected and Who Is Not

Not every solar owner is affected in the same way. Here is the breakdown:

New installations (after February 2026):
Fully under net billing from day one. The new export rate of Rs. 11 per unit applies immediately. For these buyers, the strategy from the start must be built around self-consumption, not export.

Existing net metering users (before February 2026):
Your current agreement is protected until its expiry date — typically 7 years from when you signed. You continue receiving the original credit rate until that contract ends. When renewal comes, you move to net billing.

Existing users who want to expand their system:
This is a grey area. Expanding an existing net metering system — adding panels, upgrading the inverter — may trigger reclassification to net billing depending on your DISCO and the nature of the change. Verify with MFES before making any changes to an existing net metering installation.

Why the Old Strategy No Longer Works

Under net metering, the common advice was to oversize your solar system — install more panels than your daytime consumption needs so you export heavily and accumulate credits that wipe out your night-time imports.

Under net billing Pakistan 2026 that logic reverses completely.

Every extra unit you export earns Rs. 11. Every extra unit you import costs Rs. 55. So over-exporting now costs you money compared to a correctly sized system. The optimal strategy is no longer maximum export — it is maximum self-consumption, which means using every unit your panels produce directly in your home or business.

This shift in strategy has three practical implications:

System sizing matters more. A system sized to your actual daytime consumption performs better than an oversized one under net billing. Exporting surplus you cannot use at Rs. 11 is not a feature — it is a loss compared to not generating it.

Batteries became essential. The gap between export rate (Rs. 11) and import rate (Rs. 55) is so large that storing surplus in a battery and using it yourself is now dramatically more valuable than exporting it. A unit stored in a 16kWh battery and used at 10pm saves you Rs. 55. The same unit exported earns Rs. 11. That Rs. 44 difference, compounded across thousands of cycles, is the financial case for hybrid solar in 2026.

Daytime usage should be maximised. Running heavy loads — ACs, washing machine, water heater, pumps — during solar production hours means consuming directly at Rs. 0 per unit instead of buying at Rs. 55. This is now the single most impactful thing a solar owner can do without any additional investment.

Net Billing Pakistan 2026 — The Self-Consumption Calculation

Here is what the numbers look like when you shift from an export-heavy to a self-consumption strategy:

Same household, same 10kW system, different approach:

	Export-Heavy Approach	Self-Consumption Approach
Daily solar generation	40 units	40 units
Direct self-consumption	20 units	35 units
Exported to grid	20 units	5 units
Imported from LESCO (night)	20 units	5 units (from battery)
Monthly export earnings	Rs. 6,600	Rs. 1,650
Monthly import cost saved	Rs. 33,000	Rs. 52,250
Net monthly saving	Rs. 39,600	Rs. 53,900

The self-consumption approach saves Rs. 14,300 more per month from the same system and same panels — simply by using the electricity yourself instead of sending it to the grid.

Is Solar Still Worth Installing in Pakistan After Net Billing?

Yes — and the numbers still support it clearly. Here is why:

Even under the new net billing regime, payback periods stay in the 3.5 to 4.5 year band because panel prices have fallen faster than export rates were cut. CNC Electric

The payback was 2.5 to 3 years under net metering. It is now 4 to 5 years under net billing with a correctly designed self-consumption focused system. That is still a strong return on an asset that lasts 20 to 25 years.

More importantly — self-consumed solar still saves at the full retail rate, and the fundamental value of solar self-consumption has not changed. If your LESCO tariff is Rs. 55 per unit and you generate and consume 30 units per day, you are still saving Rs. 1,650 per day — Rs. 49,500 per month — entirely unaffected by the export rate change. surgepv

Net billing only reduces the value of the portion you export. For a well-designed system with a battery, that exported portion is small.

Frequently Asked Questions

What is the export rate under net billing Pakistan 2026?
Exported electricity under the NEPRA Prosumer Regulations 2026 is compensated at approximately Rs. 10 to 13 per unit — linked to the national average energy purchase price. This compares to the old net metering rate where exports were offset at the full retail tariff of Rs. 40 to 65 per unit.

Does net billing affect my existing net metering agreement?
No — if you connected before the February 2026 cut-off date, your existing agreement remains valid until it expires. However, when your agreement comes up for renewal, it will be renegotiated under the new net billing framework. Do not expand or modify your existing system without verifying the impact with your DISCO first.

Is a battery required under net billing Pakistan 2026?
It is not legally required — but it is financially compelling. Under net billing, every unit you store in a battery and consume yourself saves Rs. 40 to 55 per unit. Every unit you export earns Rs. 11. The gap makes battery storage one of the highest-return decisions in 2026 solar planning.

Can I still get a zero LESCO bill under net billing?
With a correctly sized hybrid solar system and a 16kWh battery, your LESCO bill in peak summer months can drop to Rs. 3,000 to Rs. 8,000 from Rs. 50,000 to Rs. 80,000 — not quite zero, but close. True zero bills are harder to achieve under net billing because the fixed charges, taxes, and capacity charges on your bill cannot be offset by solar generation regardless of the system.

What happens when my net metering agreement expires?
When your existing net metering agreement expires — typically 7 years from when you signed — your connection moves to the new net billing framework. At that point, your export rate drops to the net billing rate of approximately Rs. 11 per unit. MFES recommends adding battery storage when this transition happens to maximise self-consumption before the renewal.

Should I install on-grid or hybrid under net billing?
For any home with more than minimal export — which is most homes — hybrid with battery is the correct choice under net billing 2026. On-grid systems that export during midday earn only Rs. 11 per exported unit. A hybrid system stores that surplus and uses it at full Rs. 55 value instead. See our detailed hybrid solar guide for sizes and pricing.

Conclusion

Net billing Pakistan 2026 changed the arithmetic of solar — it did not change the answer. Solar is still the most financially sound energy decision for Pakistani homeowners and businesses. The strategy has shifted from chasing export credits to maximising every unit you generate yourself. Get that right and net billing is largely irrelevant to your savings.
