NEPRA Net Metering vs Net Billing 2026

Pakistan’s 2026 prosumer framework values imported and exported units differently, so system design must focus on self-consumption instead of only exports.

An evidence-based explanation of imports, exports, agreement terms and the practical design consequences of Pakistan

Scope: This article is general information, not an equipment quotation, legal opinion, utility approval or site-specific engineering design. Regulatory note: this guide is general information reviewed on 21 July 2026. NEPRA notifications and amendments can change. Check your executed agreement, current DISCO instructions and the latest official Gazette material before making a legal or financial decision.

Net metering and net billing are not the same

Under one-for-one style net metering, imported and exported units may be offset using the applicable mechanism before the financial balance is calculated. Under net billing, the two energy flows are measured separately and valued at their respective rates. This distinction matters because a unit used directly in the building can have a different value from a unit exported to the network.

Pakistan's NEPRA Prosumer Regulations 2026 describe a net-billing arrangement. Electricity supplied by the licensee to the prosumer is billed at the applicable tariff. Electricity supplied by the prosumer to the licensee is billed using the national average energy purchase price. NEPRA may revise the export rate through notification during the agreement.

What the February 2026 regulations say

The notified regulations took effect on 9 February 2026 and replaced the 2015 distributed-generation and net-metering regulations. They cover eligible consumers, applications, technical review, interconnection, concurrence, protection, metering, billing, agreement terms and dispute resolution. Distributed generation under the framework includes qualifying solar, wind or biogas facilities from 1 kW up to 1 MW.

The proposed facility capacity generally must not exceed the sanctioned load of the premises, subject to any later notification. Applications are submitted to the relevant licensee. The regulations specify acknowledgement and review stages, agreement and connection-charge steps, metering that measures both directions, and NEPRA concurrence requirements.

How the monthly bill is conceptually calculated

• Energy flow
• Billing treatment in the 2026 regulations
• Design implication

Reducing imports during expensive periods can be valuable

Daytime self-use avoids an import that would otherwise occur

Credited at the national average energy purchase price

Do not value exports as though they equal retail imports

If the value of exported energy exceeds the value of imported energy for a billing cycle, the regulations provide for credit into the next cycle or quarterly payment by the licensee. Actual bills also depend on tariff category, fixed charges, taxes, metering dates and notified rates. A simple “units produced minus units used” calculator is therefore incomplete.

Existing agreements and amendments

The original February text contained savings provisions for licences and agreements executed under the repealed regulations. NEPRA subsequently published and notified amendments in 2026, including treatment of valid pre-existing agreements. Because legacy treatment can depend on agreement date, term and the final notified amendment, owners should read their own signed agreement and current official notification.

Do not rely on a screenshot claiming that every old consumer keeps a particular fixed rate forever, or that every old agreement immediately moved to the same method as a new connection. Ask the DISCO for a written explanation tied to the consumer reference and retain the response. For a dispute arising under the regulations, the framework provides for submission to NEPRA.

Why self-consumption now deserves more attention

When imported and exported energy have different values, the load profile becomes as important as total monthly consumption. A factory, school, office or occupied home using energy during sunshine can absorb more production directly. An evening-heavy home may export at midday and import later, producing a different financial outcome even if total generation is identical.

Designers should calculate self-consumption rather than assume it. Use interval data where available or build an hourly appliance schedule. Shift flexible loads—pumping, laundry, charging and some cooling—into solar hours when practical. Oversizing an array solely to generate large exports can weaken payback and may also face sanctioned-load or local network limits.

Does a battery solve the export-value gap?

A battery can store midday energy for evening use, but it is not automatically economical. Storage adds purchase cost, conversion loss, capacity limits, temperature sensitivity, degradation and replacement exposure. Compare the value of each shifted kWh with the battery's lifetime cost and keep backup value separate from energy-arbitrage value.

For outage resilience, define critical loads and hours first. A smaller essential-load battery can be more practical than whole-house backup. Confirm whether the selected hybrid inverter supports the intended operating mode, phase arrangement and grid-interconnection requirements.

Application and technical requirements still matter

Billing is only one part of the framework. Protection and control diagrams require licensee approval before commissioning. Interconnection equipment, disconnect arrangements, earthing, metering and inverter compliance must satisfy applicable requirements. The owner remains responsible for prudent operation and maintenance of the facility and interconnection equipment.

The 2026 regulations state that a distribution transformer may not accept an application once connected DG capacity reaches the specified proportion of transformer rating, and facilities at or above the stated threshold require a load-flow study through the licensee or a reputable PEC-registered consultant. Always check the latest text for thresholds before quoting them in a contract.

How to evaluate a solar proposal under net billing

• Separate imported, self-consumed and exported kWh.
• Use the current applicable import tariff and current notified export basis.
• Model at least one lower self-consumption case.
• Respect sanctioned load, roof and local interconnection constraints.
• Show battery economics separately from backup convenience.
• State agreement and regulatory assumptions with dates and sources.
• Avoid guaranteed savings based on an export rate that NEPRA can revise.

Net billing does not make rooftop solar useless; it changes the optimisation. Systems should be matched more carefully to on-site demand, and financial claims should distinguish avoided imports from export credits. The best design is auditable under different rate scenarios.

Frequently asked questions

Is net billing the same as selling all solar to the grid?

No. Energy used immediately behind the meter serves the building first; only surplus flows to the grid. The two-direction meter records imports and exports.

Is the export rate fixed for five years?

The agreement term is five years, but regulation 14 states that NEPRA may revise the export rate through notification during the agreement.

Can a solar system exceed sanctioned load?

The February 2026 regulations state that proposed DG capacity shall not exceed sanctioned load, subject to NEPRA's power to revise that capacity through notification.

Where should I verify the latest rule?

Use NEPRA's official legal and news pages, the current Gazette notification, your DISCO's written guidance and your executed agreement.
