Net metering lets your solar system send surplus electricity to the grid in exchange for credits that cut your bill. Under NEPRA’s 2026 Prosumer (net-billing) rules, imported units are billed at your normal tariff while exports are credited at the notified rate so self-consumption now drives savings. Approval runs through your DISCO in a few weeks; Zynergy handles the entire process.
What Is Net Metering / Net Billing?
A bi-directional meter records the units you import from the grid and the units your solar system exports. Historically Pakistan used 1:1 net metering. Under NEPRA’s 2026 Prosumer Regulations, the model shifts toward net billing: imports are billed at your normal tariff, while exports are credited at a notified rate broadly tied to the national average power-purchase price.
The practical effect: solar still cuts your bill significantly, but maximising self-consumption now matters more than ever. The net meter itself is a DISCO-approved bi-directional unit that replaces your existing meter once your application is sanctioned which is why an unapproved “backfeeding” setup is both risky and a violation of your supply agreement.

Pakistan's solar net metering policy has evolved since the original 2015 NEPRA regulations understanding the shift helps you size correctly rather than copying a neighbour's 2022-era system.
| Aspect | Classic net metering (pre-2026) | Prosumer net billing (2026) |
|---|---|---|
| Export value | Offset 1:1 against imported units | Credited at NEPRA-notified rate |
| Import value | Net of exports, at tariff | Full retail tariff on every imported unit |
| Best strategy | Oversize, export aggressively | Right-size, self-consume aggressively |
| Oversized systems | Still paid off via exports | Surplus earns less than retail rate |
| Battery case | Weak (grid was your battery) | Stronger (store cheap solar for evening) |
| Payback for right-sized homes | ~2.5-4 years | Still ~2.5-4 years with good self-consumption |
Existing net-metering customers should check the terms and validity of their current DISCO agreement; new applicants come under the prosumer framework. Either way solar remains the cheapest unit of electricity you can buy in Pakistan.
How Net Metering / Net Billing Works
Your on-grid or hybrid system powers your home first; surplus flows to the grid and is credited, while any grid units you draw are billed you pay the net amount. Because exports are credited at the notified rate, the best returns come from using more of your own solar during the day and right-sizing the system to your load.
Mechanically, the bi-directional meter logs import and export registers separately, the DISCO bills your imports at your slab tariff, applies the export credit, and the difference appears on a single bill. On sunny months a well-sized home system can push the net figure down to little more than fixed charges and taxes. There is no cheque in the post for surplus credits adjust against your bill so the goal is to zero the bill, not to run a power station.
NEPRA Prosumer Rules What Actually Changed
NEPRA’s Prosumer Regulations 2026 updated how rooftop-solar exports are valued (net billing rather than pure 1:1 netting). The policy intent is straightforward: rooftop solar grew so quickly that DISCOs were buying back daytime surplus at retail rates while still maintaining the grid that solar homes rely on every evening. Net billing rebalances that by valuing exports nearer the utility’s own purchase cost.
What it does not do is undermine the case for solar every unit you generate and use yourself still displaces a full-tariff unit, including the upper slabs, fuel-price adjustments and taxes stacked on it. The homes that feel the change are those that oversized for export income; homes sized to their own consumption see almost no difference in payback. Rules and rates can change, so always confirm the latest DISCO/NEPRA terms before signing.
How to Maximise Savings Self-Consumption Strategy
Self-consumption is now the single biggest lever on your return, and it is mostly about timing, not sacrifice. Run heavy daytime-flexible loads washing machine, water pump, dishwasher, iron between 10am and 3pm when generation peaks. Pre-cool bedrooms with the inverter AC in the late afternoon on solar power rather than hammering the grid at 8pm.
If your evening usage is heavy and your area has load-shedding anyway, a hybrid system with a modest lithium battery lets you store afternoon surplus and use it through the evening peak under net billing that stored unit is worth full retail tariff to you, more than its export credit. Sized and operated this way, typical homes self-consume 60-80% of generation and keep payback in the 2.5-4 year band.
How to Apply for Net Metering (Step by Step)
Getting the engineering pack right first time is what keeps the process short most rejections trace back to sloppy initial documentation.
- Step 1 Survey & system design. A site survey confirms roof condition, shading, phase and sanctioned load, and produces a single-line diagram and design that meet DISCO technical standards.
- Step 2 DISCO net-metering application. Filed with your DISCO (K-Electric, LESCO, IESCO, PESCO, etc.) along with the design documents, CNIC, bill and ownership papers. The DISCO reviews capacity against your sanctioned load and the local transformer’s headroom.
- Step 3 AEDB generation licence. Distributed-generation approval is processed alongside the DISCO consent effectively your licence to generate and export. We prepare and track this filing.
- Step 4 Net-meter installation & inspection. The DISCO replaces your meter with a bi-directional net meter and inspects earthing, protections, inverter settings and the changeover arrangement against the approved design.
- Step 5 Agreement signed, system goes live. You sign the prosumer agreement, the meter is commissioned, and exports begin earning credits from your next billing cycle. Keep the agreement safe it states your approved capacity and tariff treatment.
Net Metering by DISCO
The framework is national, but each DISCO runs its own counters, portals and inspection teams, so timelines and quirks differ. We've processed approvals across all of them since 2021.
| DISCO | Area | Practical notes |
|---|---|---|
| K-Electric | Karachi | Privately run; its own portal and inspection flow; coastal sites need corrosion-rated installs |
| LESCO | Lahore & central Punjab | High application volume; smog-season output planning matters for sizing |
| IESCO | Islamabad / Rawalpindi | Cooler climate flatters output; processing generally steady |
| PESCO | Peshawar & KP | Longer load-shedding makes hybrid + net metering a common pairing |
| MEPCO / FESCO / GEPCO / HESCO | South Punjab, Faisalabad, Gujranwala, Hyderabad | Same national rules; transformer capacity checks can add time in dense areas |
Net Metering Cost, Timeline & Savings
Nominal DISCO/processing fees; approval typically a few weeks. For a right-sized home the combination of self-consumption plus export credits typically removes 70-90% of the bill.
Worked Example: Net Metering on a 10KW Lahore Home
A Lahore household on LESCO with a 10KW system generates roughly 40-50 units per day in good months. The family runs two inverter ACs, a water pump and normal appliances; daytime self-consumption absorbs about 60% of generation, and the remaining ~16-20 daily units export to the grid. Imports (mostly evening units) are charged at tariff, the export credit is applied at the notified rate, and the net payable lands at a fraction of the pre-solar bill.
During the November-January smog season, generation dips 20-40%, so the family shifts more usage into midday; across the full year the bill reduction still averages around 80%, keeping the system on a 2.5-4 year payback track.
Why Net Metering Applications Get Delayed (and How We Avoid It)
Most delays are self-inflicted at filing stage. The repeat offenders: applicant name not matching the bill; system size exceeding sanctioned load with no load-extension request attached; single-line diagrams that don’t match the actual installation; missing equipment type-test certificates; and inverters set to the wrong grid parameters at inspection.
Transformer capacity is the one genuine external constraint in dense urban pockets the local transformer may already carry several solar exporters. Our process front-loads all of this: the survey verifies name, load and phase; the design pack uses DISCO-format drawings; and our team attends the inspection so settings are corrected on the spot. That is how approvals stay measured in weeks, not seasons.
Net Metering vs Battery Backup
The decision is about what problem you are solving savings, backup, or both.
If your area has minimal load-shedding, this is the purest financial play least equipment, lowest cost, fastest payback.
- No battery to buy or replace
- Surplus exported for credits
- Fastest payback
If outages are part of daily life, a hybrid system gives both: net-metering credits while the grid is up, battery power when it isn't.
- Backup through load-shedding
- Store afternoon surplus for evening
- Worth more than exporting under net billing
The wrong answer is a large off-grid-style battery bank bought “just in case” buy backup for the outages you actually experience, and let the net meter handle the rest.
Net Metering FAQs
Yes paired with a right-sized system it remains the fastest way to cut your bill, with typical reductions of 70-90% and payback in 2.5-4 years even under the 2026 net-billing rules.
Usually a few weeks for a clean application; load extensions or transformer reviews add time. We manage the whole file, which keeps it at the short end.
Up to your sanctioned load most homes net-meter 5-15KW. If you want a bigger system than your sanctioned load allows, a load extension is filed first.
Generally yes. Single-phase homes can apply to their DISCO for a phase upgrade; we routinely handle this alongside the solar installation.
K-Electric, LESCO, IESCO, PESCO, MEPCO, FESCO, GEPCO and HESCO all process applications under the national framework procedures and timelines vary slightly by office.
Nominal DISCO processing fees plus the bi-directional meter charges small line items against the system cost, included transparently in our quotes.
No. The mechanism changed from 1:1 netting to net billing exports earn the notified rate instead of full retail offset but solar self-consumption still displaces full-tariff units, so well-sized systems remain firmly profitable.
Export credits adjust against your bill rather than being paid out. The smart strategy is to size for your own consumption and treat exports as a bonus, not an income stream.
Yes hybrid systems net-meter exactly like on-grid ones. The battery covers load-shedding and lets you use stored solar in the evening instead of buying peak grid units.
For a properly sized system, expect roughly 70-90% off your bill across the year higher in long sunny months, lower in the December-January smog and short-day period.
You can, but most rejections and delays come from documentation and design-format errors. Zynergy files, tracks and attends inspection as standard it is included in our system price.
