Off-peak import
Units you bought from the grid outside peak hours. Usually the largest number on the bill.

Green meter bill calculator for Pakistan
Your solar meter shows three numbers and your bill shows three more. This page explains what registers #8, #6 and #5 mean, how to turn them into the units you actually used this cycle, and what changed when NEPRA moved new prosumers onto net billing in February 2026.

Step one
The three registers on your green meter
Press the scroll button on the meter until the register number appears in the small corner display. Each figure is a lifetime running total, not a monthly one.
Peak import
Units bought during peak hours, charged at the higher time-of-use rate.
Off-peak export
Units your panels sent back to the grid. This is what earns you credit.

Step two
A worked example
For each register: present meter reading − reading on your last bill. Then net the three results and add anything carried forward.
| Register | Meter now | On last bill | This cycle |
|---|---|---|---|
| #8 Off-peak import | 12,480 | 12,180 | −300 |
| #6 Peak import | 3,120 | 3,040 | −80 |
| #5 Off-peak export | 9,640 | 9,000 | +640 |
| Previous surplus | - | - | +60 |
| Net surplus | - | +320 kWh | |
640 exported − (300 + 80) imported + 60 carried forward = 320 kWh in credit. If your utility applies an export deduction percentage, enter it in the calculator and it comes off the export figure before the netting.

Net metering or net billing - which are you on?
Grandfathered: net metering
If you held a valid net-metering agreement on 9 February 2026, your old terms continue until that agreement expires. Exports and imports still net 1:1, so a single unit price values the whole balance.
In the calculator: choose Net metering and enter your retail tariff as the unit price.
New prosumers: net billing
Applications after the cut-off fall under NEPRA’s Prosumer Regulations 2026. You buy at the retail tariff and sell exports at a separate, lower buyback rate, and permitted system size is tied to your sanctioned load.
In the calculator: choose Net billing and enter your off-peak, peak and buyback rates. It prices imports and exports separately and shows your estimated bill.
Buyback rates are set by regulatory determination and have already moved more than once, so we do not print a figure that might be out of date - confirm yours with your DISCO or NEPRA. The full breakdown of what changed .

Questions
Green meter questions, answered
What is a green meter in Pakistan?
A green meter is the bidirectional net meter your DISCO installs when your rooftop solar is approved. It counts electricity in both directions - what you take from the grid and what you send back - on separate registers. "Green meter", "net meter" and "netmeter" all mean the same device.
How do I read registers 5, 6 and 8 on my green meter?
Press the meter’s scroll button until the register number appears in the small corner display. #8 is off-peak import, #6 is peak import and #5 is off-peak export. Each is a lifetime running total, so subtract the matching figure printed on your last bill to get this cycle’s units.
How do I calculate my LESCO or IESCO net metering bill?
For every register, take the present meter reading minus the reading on your last bill. Add off-peak and peak imports together, subtract that total from your export units, then add any surplus carried forward. A positive answer is credit; a negative one is what you will be billed for. This calculator does all of it as you type.
Did Pakistan really end net metering in 2026?
For new applicants, yes. NEPRA’s Prosumer Regulations 2026, notified on 9 February 2026, replaced net metering with net billing: imports are bought at the retail tariff and exports are sold back at a separate, lower rate rather than netted 1:1. Consumers holding a valid net-metering agreement on that date continue on the old terms until their agreement expires.
Does the calculator still work under net billing?
Yes. Switch the calculator to “Net billing” and enter your off-peak, peak and buyback rates. The registers and the unit arithmetic are unchanged; the calculator prices imports and exports separately and shows how much more the same exports would have earned under 1:1 net metering.
How big a solar system am I allowed under the 2026 rules?
The regulations tie permitted capacity to your sanctioned load, where the earlier framework was more generous. Confirm your sanctioned load on your bill and check the current limit with your DISCO before ordering a system.
What is the current export buyback rate?
It is set by regulatory determination and has moved more than once, with figures reported inconsistently while the rules were being finalised. We deliberately do not print a number here that could be stale. Ask your DISCO in writing, or check NEPRA’s notified determination, and enter that figure as the buyback rate in the calculator’s net billing mode.
