Pakistan Solar Regulations: NEPRA Net Billing 2026

Last updated: November 2026

Pakistan’s rooftop solar boom was driven by high grid tariffs and frequent outages rather than by subsidy. That growth collided with grid economics, and the result is the regulatory shift every installer in Pakistan now works around: the move from retail net metering to net billing. NEPRA notified new rules in February 2026, according to Dawn (10 February 2026).

This guide covers the framework as it stands: what changed in 2026, NEPRA’s role and the 2015 Net Metering Regulations, the prosumer application process through the DISCOMs, what net billing does to project economics, equipment and technical standards, and a compliance checklist for installers.

What Changed in 2026: Net Billing Replaces Net Metering

NEPRA moved Pakistan’s rooftop solar customers from net metering to net billing in early 2026. The table summarizes what the press reported. Dates and figures come from news coverage of NEPRA’s decisions, so read the notified regulation text before you quote.

Dawn also reports that a different export rate, Rs26 per unit, applies to existing prosumers’ surplus under their old agreements. The December draft cited Rs22 for the same group, so sources disagree on that figure. Confirm it from NEPRA’s notification if you manage legacy customers.

NEPRA and the Regulatory Structure

The National Electric Power Regulatory Authority (NEPRA) is Pakistan’s federal power regulator, established under the 1997 Electric Power Act. Its role in distributed solar: issuing the prosumer and net metering regulations, approving tariff and buyback determinations, and licensing generation.

Below NEPRA sit the distribution companies (DISCOMs): LESCO (Lahore), IESCO (Islamabad), K-Electric (Karachi), FESCO, MEPCO, PESCO, GEPCO, HESCO, SEPCO, QESCO, and TESCO. K-Electric is privately run; the rest are state-owned. Each DISCOM processes net metering applications, conducts technical reviews, signs the net metering agreement, and installs the bi-directional meter. NEPRA writes the rules; the DISCOMs execute them, and speed and rigor vary. NEPRA’s determinations and the regulation text are published on the NEPRA website.

The 2015 Net Metering Regulations: How They Work

NEPRA’s Distributed Generation and Net Metering Regulations, notified in September 2015, made Pakistan one of the earlier South Asian markets with a formal net metering framework. The core mechanics:

• Eligibility: any consumer of a DISCOM, with a distributed generation facility (solar or wind) from 1 kW to 1 MW.
• Prosumer status: the consumer becomes a “distributed generator”. Under the 2015 rules net-metered systems did not need a generation licence; the 2026 rules put 1 kW to 1 MW systems under NEPRA’s regulatory and licensing domain, per Dawn, with systems below 25 kW licensed directly by DISCOMs.
• Metering: the DISCOM installs a bi-directional meter recording import and export separately.
• Compensation: exported units were credited against imported units on the monthly bill, effectively retail-rate netting with excess carried forward. This is the model the 2026 rules replaced.
• Agreement: a standardized net metering agreement between consumer and DISCOM, typically running with the connection.

These mechanics fed the boom: with high retail tariffs, every self-consumed or netted kWh avoided an expensive grid kWh.

The DISCOM Application Process

The standard path from contract to energized net metering:

1. Application to the DISCOM with consumer details, sanctioned load, system size, single-line diagram, and equipment specs.
2. Technical review: the DISCOM checks transformer loading, feeder capacity, and protection requirements. Oversized applications relative to sanctioned load get rejected or require a load extension first.
3. Approval and agreement: the DISCOM issues approval; the consumer signs the net metering agreement.
4. Installation by the installer to DISCOM technical standards.
5. Inspection and meter installation: the DISCOM inspects, replaces the meter with a bi-directional unit, and energizes export.

Approval time varies by DISCOM and by how complete the application is, so ask the DISCOM for its current service standard. Build the approval window into project cash-flow planning, because most financing milestones hang off meter installation.

The Net Billing Transition

The policy issue: as distributed solar scaled up, exported solar credited at retail rates shifted grid costs onto customers without solar. The government and NEPRA reviewed the framework. Under the notified rules, per Dawn, surplus exports are bought at the national average energy purchase price (about Rs10 to Rs11 per unit for new prosumers) while imports bill at the consumer tariff, and the net difference is billed. If a prosumer’s credit exceeds the bill, it carries forward or is paid quarterly, though Dawn notes DISCOMs have not made such payments in the past.

Practical consequences for new projects:

• Export value drops. Selling surplus to the grid is no longer the business case; avoiding grid purchases is.
• Sizing inverts. Optimal design targets daytime self-consumption, matching the array to the load curve instead of to annual consumption.
• Batteries move up the agenda. With evening grid power expensive and exports cheap, storage that shifts solar to evening use can carry more of the project economics. Run the numbers for each customer, because battery cost and tariff slab decide it.
• Existing prosumers: they were moved to net billing as well, with a shorter credit window, and keep other terms until their contracts end, per Dawn. Check the notified text before advising a legacy customer.

For proposals, this means modeling the actual post-transition purchase rate, not the retail offset. A generation and financial tool that separates self-consumption value from export value shows the real return. Annual netting spreadsheets overstate savings under net billing.

Equipment and Technical Standards

DISCOM technical requirements center on the inverter: it must be a certified grid-tie inverter with anti-islanding protection (automatic disconnection during grid outages, which matters in a market with frequent load-shedding). Hybrid inverters paired with batteries must be configured so battery-backed loads do not export during outages.

Other standards that show up in DISCOM reviews:

• System size consistent with sanctioned load.
• Proper AC/DC protection: breakers, surge protection, earthing.
• Single-line diagram signed by the installer.
• Bi-directional meter supplied and installed by the DISCOM, at the consumer’s cost.

For inverter selection in the Pakistani market, treat voltage fluctuation and outage frequency as design inputs rather than edge cases. Verify the exact model’s local certification, grid settings, battery compatibility, warranty route, and commissioning support in Pakistan instead of extrapolating claims from another country.

C&I and Captive Solar

Much of Pakistan’s solar growth is captive C&I: factories installing solar, often with storage or diesel hybridization, primarily for self-supply, with or without a net billing agreement. Captive systems that never export can operate without a net metering agreement, though grid parallel operation still requires DISCOM technical compliance.

For C&I prosumers, self-consumed solar remains valuable because it displaces the customer’s own tariff, while export revenue was always secondary. The design emphasis shifts to load matching: sizing solar against the factory’s daytime load curve rather than its total annual consumption. Shading analysis and production modeling in a solar design platform matter here, because a mismatched 500 kW roof exports midday surplus at the low purchase rate.

For comparison, neighboring India runs a similar DISCOM-level net metering regime with its own caps and banking rules. Heaven Green Energy’s India net metering guide is a useful contrast for regional installers working both markets.

Installer Compliance Checklist

Before quoting any grid-tied system in Pakistan:

• Check the latest NEPRA determination on buyback rates, since the framework is still being adjusted.
• Verify sanctioned load. Dawn reports new systems cannot exceed it, so a load extension may come first.
• Specify inverters on the DISCOM’s accepted list with anti-islanding certification.
• Budget the bi-directional meter cost and the DISCOM processing window into the project plan.
• Document the agreement terms, especially the compensation basis, in the customer file.
• For hybrid systems, configure export blocking for outage operation and note it in the inspection documents.

Taxes, Duties, and Equipment Costs

Pakistan’s solar hardware economics have been shaped by import policy. Solar panels have generally enjoyed favorable duty treatment to encourage adoption, while inverters and batteries have faced varying sales tax and duty regimes across budget cycles. The federal budget has adjusted taxes on solar equipment in recent years, so the landed cost of modules and hybrid inverters can move between fiscal years.

For installers, the practical rules: quote equipment prices with a short validity window, track the current fiscal year’s duty schedule before large procurement commitments, and pass duty changes through as a documented surcharge rather than absorbing them. Global module prices and the rupee exchange rate both feed into local prices, so quote with an exchange-rate assumption written down.

Provincial Variations Worth Knowing

Net metering is federal, but the operating environment is provincial:

• Punjab (LESCO, MEPCO, FESCO, GEPCO): the largest rooftop market; LESCO processes the highest application volumes.
• Sindh (K-Electric, HESCO, SEPCO): K-Electric runs its own privatized process with separate queues and its own tariff determinations.
• KP (PESCO) and Balochistan (QESCO): lower volumes and more variable processing; weaker rural feeders can mean more capacity-related technical rejections.

The application paperwork is similar everywhere; the processing culture is not. Installers working several provinces benefit from keeping a DISCOM-specific contact and checklist for each region.

What Most Installers Get Wrong

The dominant error is selling legacy net metering economics in a net billing market. Proposals quoting unit-for-unit offset for new systems overstate savings, and customers notice when the first bill arrives.

Second: ignoring sanctioned load. Systems designed above the connection’s sanctioned load stall at technical review. Check the electricity bill before the site survey.

Third: undersizing protection and earthing to hit a price point. Failed DISCOM inspections cost schedule time. Systems designed for zero export may face a lighter process, but confirm that with the DISCOM rather than assuming it.

Conclusion

Pakistan’s solar market runs on avoided cost now, not export revenue. Three actions this week:

• Pull the current NEPRA buyback determination and rebuild your proposal template’s export assumptions.
• Re-train sales teams on the self-consumption pitch: avoided tariff slabs, not sell-back.
• Add sanctioned-load verification to your lead intake form.

Frequently Asked Questions

What is NEPRA and what does it regulate?

NEPRA is the National Electric Power Regulatory Authority of Pakistan, created under the Regulation of Generation, Transmission and Distribution of Electric Power Act 1997. It licenses generation, approves tariffs, and issues the net metering and prosumer regulations that govern rooftop solar interconnection.

Did Pakistan end net metering for solar?

Yes, in effect. Per Dawn (10 February 2026), NEPRA notified regulations that move all prosumers to net billing. New prosumers’ exports are bought at about Rs11 per unit on five-year contracts, while existing prosumers keep other contract terms until their seven-year agreements expire. Read the notified text before quoting.

How does net billing work for solar in Pakistan?

Under net billing, the DISCOM bills your consumption at the consumer tariff and credits your exports at a separate, lower rate, then bills the difference. Dawn reports import rates of Rs37 to Rs55 per unit before taxes and an export credit of about Rs11 per unit for new prosumers. Self-consumption is worth far more than export.

How does net metering work in Pakistan?

Under NEPRA’s 2015 regulations, a consumer installed solar from 1 kW to 1 MW, applied through the local DISCOM, and got a bi-directional meter. Exported units were credited against imported units on the monthly bill. That unit-for-unit model is the one the 2026 net billing rules replaced.

What is the maximum system size for solar in Pakistan?

The framework covers distributed generation systems from 1 kW up to 1 MW per consumer. Dawn reports that new systems also cannot exceed the connection’s original sanctioned load, and DISCOMs stop accepting applications once distributed generation on a transformer reaches 80% of its rating.

Do I need a license to install solar in Pakistan?

It depends on system size under the current rules. Under the 2015 regulations net-metered systems did not need a generation licence. Dawn reports the 2026 rules place 1 kW to 1 MW systems under NEPRA’s regulatory and licensing domain, with systems below 25 kW licensed directly by DISCOMs. Check with your DISCOM before applying.

How long does DISCOM approval take for rooftop solar?

Approval time varies by DISCOM and by how complete your application is. The steps are application, technical review of transformer and feeder capacity, agreement signing, installation, inspection and meter replacement. Ask your DISCOM for its current service standard, and build the window into your project cash flow.
