What is Net Metering?
Net metering is a billing arrangement regulated by NEPRA (National Electric Power Regulatory Authority) that allows consumers who generate electricity from solar or other renewable sources to export their surplus production to the national grid and receive credit for it. This credit offsets the electricity you draw from the grid at other times, effectively reducing your monthly electricity bill.
The term 'net metering' refers to the fact that your DISCO bills you only for the 'net' electricity you consume — that is, the amount you import from the grid minus the amount you export from your solar system. If you generate more than you consume in a billing period, you build up credit for future periods.
Net metering was formally introduced in Pakistan through NEPRA's Alternative and Renewable Energy (Distributed Generation and Net Metering) Regulations 2015, and has since been updated multiple times. It is now available through all 11 DISCOs and K-Electric, covering residential, commercial, and industrial consumers across Pakistan.
Eligibility and System Requirements
Any consumer connected to a DISCO or K-Electric grid can apply for net metering, subject to certain conditions. There is no restriction based on geographic location, though technical feasibility on your specific grid feeder must be confirmed by the DISCO.
Net Metering Eligibility Criteria in Pakistan
| Criterion | Requirement |
|---|---|
| Consumer type | Domestic, commercial, industrial, or agricultural |
| System size | Minimum 1 kW, maximum equal to your sanctioned load |
| Inverter type | Grid-tied, NEPRA-approved inverter only |
| Net metering cap | System capacity not to exceed sanctioned load |
| Technology | Solar PV, wind, or other NEPRA-approved renewables |
Your solar system must use a grid-tied inverter (not an off-grid or hybrid-only inverter). The inverter must be on NEPRA's approved equipment list. Your installer is responsible for ensuring compliance, so choose a certified AEDB (Alternative Energy Development Board) registered installer.
The Net Metering Application Process
Applying for net metering in Pakistan involves several steps and coordination between you, your installer, and your DISCO. While the process has been streamlined in major cities, it still requires patience — especially regarding the inspection and meter replacement steps.
- Step 1: Hire a NEPRA/AEDB-certified solar installer (they handle the application for most consumers)
- Step 2: Installer submits application to your DISCO with: system design drawing, single-line diagram, equipment specs, installer certificate, and prescribed fee
- Step 3: DISCO reviews the application for technical completeness (5–15 business days)
- Step 4: DISCO conducts a physical inspection of your site and proposed system
- Step 5: DISCO issues a feasibility letter (approval in principle)
- Step 6: Solar system is installed by your installer
- Step 7: DISCO conducts final inspection of the installed system
- Step 8: DISCO replaces your standard meter with a bidirectional net meter
- Step 9: Net metering commences — your bills now reflect net consumption
The total time from application to meter replacement typically ranges from 30 to 120 days, depending on your DISCO and any backlog of applications. LESCO and IESCO tend to be faster than some of the smaller DISCOs in less urbanized areas.
How Net Metering Billing Works
Once your net meter is installed and activated, your DISCO reads both import and export units every month. Your bill is calculated on the net difference.
Net Metering Billing Example
| Component | Value | Note |
|---|---|---|
| Units imported from grid | 200 kWh | Consumed from DISCO grid |
| Units exported to grid | 150 kWh | Surplus solar generation |
| Net consumption | 50 kWh | 200 - 150 = 50 units net |
| Energy charge (Slab 1) | 50 × Rs 7.74 = Rs 387 | Only net units billed |
| FPA on 50 units | 50 × Rs 3.00 = Rs 150 (example) | Based on current FPA rate |
| GST and taxes on Rs 537 | Rs 91 | 17% GST approximately |
| Total bill (approx) | Rs 628 instead of ~Rs 6,000+ | Vs full grid consumption |
If you export more than you import in a billing period, you accumulate net export units as a credit. This credit is carried forward to the next billing period. NEPRA regulations allow the credit to accumulate for up to 12 months, after which any remaining credit is settled by your DISCO at the 'avoided cost' rate (lower than your consumer tariff rate).
Net Metering Costs and One-Time Fees
Beyond the cost of the solar system itself, you will incur certain regulatory fees as part of the net metering application. These are government-mandated and non-negotiable.
Typical Net Metering Application Fees (Approx)
| Fee Item | Amount (Rs) | Paid To |
|---|---|---|
| DISCO application processing fee | 5,000 – 10,000 | Your DISCO |
| Net meter installation / replacement fee | Included or 2,000 – 5,000 | Your DISCO |
| NEPRA surcharge (if applicable) | Variable | NEPRA via DISCO |
Note that different DISCOs charge slightly different fee structures. Your installer should be able to quote the specific fees for your area. The net meter (bidirectional meter) itself is typically supplied and installed by your DISCO — you do not purchase it separately.
Net Metering Savings: Real Numbers
The financial benefit of net metering depends on the size of your system, local solar irradiance, your consumption pattern, and current electricity tariff rates. Here is a realistic example for a 4 kW system in Lahore:
- System size: 4 kW on-grid with net metering
- Average solar generation: ~160–170 kWh per month (year-round average)
- Average household consumption: 400 kWh per month
- Net import from grid: 400 - 165 = 235 kWh
- Bill reduction vs full grid: from ~Rs 18,000 to ~Rs 8,000 per month (savings of ~Rs 10,000)
- Annual savings: ~Rs 120,000
- System cost: ~Rs 380,000
- Break-even (payback): ~3.2 years
Frequently Asked Questions
What is NEPRA net metering in Pakistan?
Net metering is a NEPRA-regulated billing arrangement where solar consumers export surplus electricity to the national grid and receive credit for it. Only the 'net' difference between import and export is billed, dramatically reducing monthly electricity costs.
How long does net metering approval take in Pakistan?
The process from application to active net metering typically takes 30–90 days in major cities and up to 120 days in smaller areas. DISCO inspection scheduling is often the bottleneck. A certified installer usually manages the entire process.
Is net metering available in all cities in Pakistan?
Yes. All 11 DISCOs and K-Electric are required to offer net metering to eligible consumers under NEPRA regulations. However, technical feasibility on your specific grid feeder must still be confirmed by your DISCO.
What happens to my excess solar credit if I generate more than I consume?
Excess generation is carried forward as credit units to the next billing period. Credits can accumulate for up to 12 months. After 12 months, any remaining credit is settled by the DISCO at the avoided cost rate, which is lower than your consumer tariff rate.
Can I get net metering for a commercial property in Pakistan?
Yes. Commercial consumers (B-category) are fully eligible for net metering. The application process and required documentation are the same. Commercial net metering can significantly reduce operating costs for businesses.
Do I need battery storage for net metering to work?
No. Grid-tied (on-grid) solar systems without batteries are fully compatible with net metering. The grid acts as your virtual battery — you export during the day and import at night. Batteries are optional and only needed if you want backup power during load shedding.
What if my DISCO rejects my net metering application?
If your DISCO rejects on technical grounds (grid capacity constraints), you can appeal to NEPRA or request a formal letter explaining the rejection. If it is a documentation issue, simply resubmit with corrected paperwork. Net metering cannot be refused without a valid technical reason.
Does net metering reduce my FPA charges?
Yes. FPA is charged per unit of net consumption. By reducing your net import from the grid through solar generation, you pay FPA only on the remaining net units. This can be a large saving in months with high FPA rates.
What happens to my net metering if I shift house or sell the property?
Net metering is registered to the connection, not the individual. If you sell your property, the solar system and net metering registration typically transfer with the property. You need to notify your DISCO of ownership changes.
Can I get net metering if I am in a rented property?
Technically yes, but net metering is registered under the electricity account holder's name — typically the property owner. You would need the owner's consent and cooperation to apply. Some renters negotiate solar installation as part of rental agreements with cost-sharing on energy savings.
