Pakistan Net Billing 2026 Explained: What Solar Users Need to Know

Pakistan’s solar billing framework changed significantly in 2026.

For years, many rooftop solar users understood grid-connected solar through the idea of net metering: electricity exported to the grid could offset electricity imported from it under the applicable billing mechanism.

The National Electric Power Regulatory Authority introduced a different framework on February 9, 2026 through the NEPRA Prosumer Regulations, 2026.

For new prosumers, the system now operates on net billing.

That distinction matters because electricity taken from the grid and electricity sent back to the grid are no longer treated as equivalent units for billing purposes.

If you are considering a new solar installation in Pakistan, understanding that difference should come before deciding how large your system should be, whether you need batteries, or how much surplus electricity you expect to export.

What Is Net Billing in Pakistan?

Net billing is a billing arrangement in which electricity imported from the distribution company and electricity exported by the prosumer are accounted for separately.

Under the NEPRA Prosumer Regulations, 2026:

• Electricity supplied by the distribution company to the prosumer is billed at the applicable consumer tariff.

• Electricity supplied by the prosumer to the distribution company is credited at the National Average Energy Purchase Price.

In practical terms, the electricity you buy from the grid and the surplus solar electricity you sell back to the grid do not carry the same billing value.

That is the central difference solar buyers need to understand in 2026.

Net Billing vs Net Metering: What Changed?

Under the previous net-metering framework, imported and exported electricity were adjusted under the billing mechanism established by the earlier regulations.

The 2026 Prosumer Regulations repealed the 2015 Distributed Generation and Net Metering Regulations for new arrangements and introduced the current net-billing framework.

For a new solar customer, this means the investment should not be designed around the assumption that every exported unit will offset an imported unit at the same value.

Directly using solar electricity at the property has therefore become more important.

If your solar panels generate electricity while your appliances, air conditioning, machinery, pumps or other loads are operating, that solar energy can serve those loads directly.

If your system generates more than you are using at that time, eligible surplus electricity can be exported and credited according to the applicable net-billing rules.

Why Self-Consumption Matters More Under Net Billing

Self-consumption is the portion of solar electricity that you use at your own property instead of exporting it.

Consider a simple example.

Two homes may both have similar solar systems.

Home A uses air conditioning, pumps and other appliances throughout the day.

Home B is mostly empty until evening.

Home A may consume much more of its solar generation directly, while Home B may export a larger daytime surplus and later import electricity after sunset.

The total solar generation could be similar, but the financial outcome may be different because direct consumption and exported electricity are treated differently.

This is one reason system sizing should now pay close attention to your daytime load.

Our guide on whether solar is still worth it in Pakistan after net billing explains this relationship in more detail.

What Is the National Average Energy Purchase Price?

The National Average Energy Purchase Price, commonly referred to as NAEPP, is the benchmark referenced in the Prosumer Regulations for electricity supplied by a prosumer to the distribution company.

It should not be confused with your normal retail electricity tariff.

The regulations allow the applicable export-credit framework to operate according to the notified regulatory mechanism, which means solar customers should verify the current applicable rate rather than relying on an old figure found in a blog, quotation or social-media post.

For that reason, a solar proposal should not assume a fixed export rate throughout the entire life of the system unless that assumption is supported by the current applicable rules.

E&E Industries does not recommend basing a solar investment solely on an unverified buyback figure.

Does Net Billing Mean Exporting Solar Electricity Is Useless?

No.

Exporting surplus solar electricity can still have value.

The important change is that the economics of exporting should be evaluated separately from the economics of consuming solar electricity directly.

For example, if your property naturally has strong daytime loads, much of your solar generation may be consumed before it ever reaches the grid.

Examples include:

• Offices operating during business hours.

• Factories running daytime production.

• Shops and commercial facilities.

• Schools and institutions.

• Agricultural pumping operations.

• Homes with substantial daytime occupancy.

A system with strong self-consumption may therefore be evaluated differently from one designed primarily around large exports.

Net billing does not make grid-connected solar irrelevant. It makes load analysis and system sizing more important.

Who Can Apply as a Prosumer?

The Prosumer Regulations define eligible applicants around specified grid-connected consumer categories.

The framework covers 3-phase 400V or 11kV consumers in categories including:

• Domestic.

• Commercial.

• Industrial.

• Agricultural.

• General services.

• Single-point bulk supply consumers.

A prosumer is essentially an eligible consumer that has entered into the required distributed-generation agreement with the relevant distribution licensee.

The distributed-generation framework covers renewable generation using solar, wind or biogas, with facilities of up to 1 MW under the regulations.

How Large Can a Net-Billing Solar System Be?

A common mistake is assuming that the maximum system size is determined only by how much roof space is available.

Under the Prosumer Regulations, the capacity of a proposed distributed-generation facility must not exceed the sanctioned load of the applicant’s premises.

The regulatory framework covers distributed-generation facilities up to 1 MW.

That means both the electrical connection and the proposed generation capacity matter during the application process.

For systems of 250 kW or above, the regulations also require a load-flow study to be conducted through the licensee or a reputable consultant registered with the Pakistan Engineering Council.

Large commercial and industrial projects therefore require considerably more technical planning than simply choosing panel capacity from an electricity bill.

What Changed for Systems of 25 kW or Below in August 2026?

One of the most important recent changes came on August 6, 2026.

NEPRA issued S.R.O. 1330(I)/2026, amending the Prosumer Regulations.

Under the amended rules, a prosumer with a distributed-generation facility of 25 kW or below does not need to obtain concurrence from NEPRA.

Instead, the concerned distribution licensee provides the approval.

For many residential and smaller commercial solar installations, this removes a separate NEPRA concurrence step from the process.

Systems above 25 kW remain subject to the applicable NEPRA concurrence requirements.

Because this amendment is recent, applicants should use the latest procedures published by their relevant distribution company rather than relying on an older net-metering application guide.

Are There NEPRA Fees for Solar Systems?

NEPRA’s 2026 fee framework was also amended during the year.

For distributed-generation facilities of 25 kW or below, the applicable NEPRA concurrence fee is nil.

For facilities above 25 kW, the notified concurrence fee is PKR 1,000 per kW as a one-time fee.

However, because systems of 25 kW or below now proceed through the concerned distribution licensee without NEPRA concurrence under the August amendment, applicants should separately verify any processing, metering or interconnection charges that may apply through their distribution company.

Do not assume that “no NEPRA concurrence fee” means that every part of the interconnection process is free.

What Happens if the Local Transformer Is Already Heavily Loaded?

Grid capacity can affect whether a new distributed-generation application can proceed.

The Prosumer Regulations state that a distribution licensee will not entertain a new application where the distributed-generation capacity already connected to a particular distribution transformer has reached 80% of that transformer’s rated capacity.

This is an important practical issue.

A property may have:

• Enough roof space.

• Suitable electricity consumption.

• An appropriate sanctioned load.

• A technically viable solar design.

Yet local network conditions can still affect interconnection.

The regulations also provide a route where required distribution-system improvements may be undertaken at the prosumer’s cost where applicable.

This is why grid-interconnection feasibility should be checked before treating a solar proposal as final.

What Happens to Existing Net-Metering Customers?

This question created considerable concern when the new rules were introduced.

NEPRA subsequently amended the regulations through S.R.O. 547(I)/2026 in April 2026.

The amendment protects distributed generators that already had valid agreements executed under the repealed regulations before the new Prosumer Regulations came into force.

Those valid existing agreements continue to be billed according to the rate and mechanism provided under the repealed framework until the expiry of the agreement term.

There is an important qualification.

The protection can cease where a material modification to the distributed-generation facility changes its maximum electrical output.

Existing users considering an expansion should therefore confirm the regulatory consequences before increasing system capacity.

Once an existing protected agreement reaches the end of its term, future arrangements are subject to the applicable regulatory framework at that time.

How Long Is a New Prosumer Agreement?

Under the 2026 framework, the initial distributed-generation interconnection agreement is for five years from the commissioning date.

It may be renewed for subsequent five-year periods with mutual consent, subject to the applicable framework.

This matters when evaluating a solar project because regulations, tariffs and export-credit mechanisms can change over time.

A financial model should therefore avoid assuming that every regulatory parameter will remain unchanged for the entire physical life of the solar equipment.

Does Net Billing Apply Only to Residential Solar?

No.

The Prosumer Regulations apply across multiple eligible consumer categories, including domestic, commercial, industrial and agricultural consumers.

The effect of net billing can actually differ significantly by customer type.

A commercial building or factory may consume a high percentage of its solar generation directly because its operations occur during daylight hours.

A residence with most consumption occurring in the evening may export more electricity during the day and import more electricity later.

An agricultural application may have daytime pumping loads that align naturally with solar generation.

The correct system strategy therefore depends heavily on the load profile rather than simply whether the customer is residential or commercial.

How Should Homeowners Respond to Net Billing?

For residential buyers, the first priority should be understanding when electricity is consumed.

Review:

• Monthly electricity units.

• Summer and winter consumption.

• Daytime occupancy.

• Air-conditioning schedules.

• Pumps and other daytime loads.

• Evening consumption.

• Backup requirements.

• Future electrical loads.

Then calculate the system around realistic consumption rather than choosing the largest package within budget.

If most electricity use occurs after sunset, battery storage may deserve consideration — but storage should still be justified by backup needs, load shifting and overall project economics.

Our electricity-bill sizing guide explains how consumption history can be used as the starting point for system selection.

How Should Businesses Respond to Net Billing?

Businesses should focus heavily on their daytime load profile.

A commercial or industrial facility operating during solar-generation hours can often consume a significant portion of solar production directly.

A proper assessment should evaluate:

• Operating hours.

• Working days.

• Machinery and equipment loads.

• Peak demand.

• Seasonal operations.

• Weekend consumption.

• Future expansion.

• Generator use.

• Battery requirements.

• Available roof or ground area.

For larger systems, the value of accurate load data becomes even greater.

A professionally engineered commercial system should be designed around actual operational demand rather than a generic kW package.

Does Net Billing Mean Everyone Should Install Batteries?

No.

Net billing has increased interest in battery storage because batteries can allow some daytime solar generation to be used later.

But that does not automatically make batteries the best financial decision for every property.

A battery adds:

• Equipment cost.

• Usable-capacity limitations.

• Charging and discharging losses.

• Lifecycle considerations.

• Additional system complexity.

Storage may be worthwhile where backup is valuable, nighttime loads are significant or reducing grid dependence is a priority.

An on-grid system without batteries can still be entirely appropriate for a property with strong daytime consumption and limited backup requirements.

The choice between on-grid, hybrid and off-grid solar should therefore be made from the load requirements rather than from the billing policy alone.

Should You Oversize Solar to Export More Electricity?

Not automatically.

Under the current framework, installing significantly more capacity than a property can use directly deserves careful financial analysis.

A better sequence is:

1. Understand annual electricity consumption.

2. Measure or estimate daytime demand.

3. Identify the target solar offset.

4. Model expected solar generation.

5. Estimate self-consumption.

6. Evaluate likely exports.

7. Review battery requirements.

8. Confirm sanctioned load and interconnection feasibility.

9. Finalize system capacity.

This process is more defensible than selecting capacity primarily to maximize exported units.

What Should You Check Before Signing a Solar Proposal?

A solar proposal prepared for Pakistan’s current regulatory environment should explain:

• Proposed solar capacity.

• Existing sanctioned load.

• Estimated annual generation.

• Expected daytime self-consumption.

• Expected surplus generation.

• Applicable grid-interconnection process.

• Whether NEPRA concurrence is required.

• Metering requirements.

• Battery capacity, if included.

• Backup loads.

• System protections.

• Any assumptions used for export credits.

• Applicable approvals and fees.

Ask the installer to separate confirmed regulatory facts from financial assumptions.

A quotation that depends heavily on an assumed export rate should clearly identify that assumption.

Net Billing Changes the Strategy, Not the Basic Value of Solar

Pakistan’s 2026 net-billing framework has changed how grid-connected solar projects should be evaluated.

The strongest projects are no longer necessarily those designed to export the largest possible amount of electricity.

The focus should be on matching solar generation to actual electricity consumption.

For homes, that means understanding daytime and evening loads.

For businesses, it means studying operating hours and production demand.

For larger commercial and industrial projects, it means proper engineering, grid assessment and energy modeling.

Solar can still provide meaningful value, but the design needs to reflect the regulatory environment that exists now — not the assumptions that applied under the previous net-metering system.

E&E Industries provides on-grid, hybrid and off-grid solar solutions for residential, commercial, industrial and agricultural applications. Before selecting system capacity, the project should be assessed against electricity consumption, site conditions, backup requirements and the current interconnection framework.

Frequently Asked Questions

What is net billing for solar in Pakistan?

Net billing separately accounts for electricity imported from the distribution company and surplus electricity exported by the prosumer. Imports are billed at the applicable consumer tariff, while eligible exports are credited according to the National Average Energy Purchase Price under the Prosumer Regulations.

When did Pakistan’s 2026 net-billing rules start?

The NEPRA Prosumer Regulations, 2026 were notified on February 9, 2026 and came into force immediately.

Is net billing the same as net metering?

No. Net billing separately values imported and exported electricity. The previous net-metering framework operated under the repealed 2015 regulations and used a different billing mechanism.

Do solar systems of 25 kW or below need NEPRA approval?

Following NEPRA’s August 6, 2026 amendment, distributed-generation facilities of 25 kW or below do not require NEPRA concurrence. Approval is handled by the concerned distribution licensee.

Are existing net-metering users moved automatically to net billing?

Valid agreements executed under the repealed regulations before the commencement of the 2026 framework received protection under NEPRA’s April 2026 amendment and continue under the applicable previous rate and mechanism until their agreement expires, subject to the amendment’s conditions.

Can I install a solar system larger than my sanctioned load?

Under the Prosumer Regulations, the proposed distributed-generation capacity must not exceed the sanctioned load of the applicant’s premises.

Is there a maximum size under the Prosumer Regulations?

The distributed-generation framework covers eligible facilities up to 1 MW, subject to the other capacity, technical and interconnection requirements in the regulations.

Does net billing make solar batteries mandatory?

No. Batteries remain a design choice. They may provide backup and increase the ability to use solar electricity later, but their cost and capacity should be evaluated against the property’s actual requirements.
