By PSI Editorial · 6 min · Updated August 21, 2026
💡 Quick Summary & Key Takeaways
- Covered DISCOs: LESCO, IESCO, FESCO, GEPCO, MEPCO, PESCO, HESCO, SEPCO
- Export Adjustment: 1:1 offsetting for off-peak units
- Quarterly Settlement: Cash payment or credit for net surplus energy
- Meter Type: Three-Phase 4-Wire Bidirectional Electronic Meter
1. WAPDA DISCO Net Metering Framework
Each state-owned electricity distribution company operates under unified NEPRA guidelines. Whether you are connected to LESCO in Lahore, IESCO in Islamabad/Rawalpindi, FESCO in Faisalabad, or MEPCO in Multan, the technical criteria for solar grid export remain standardized.
2. How WAPDA Bills Net Metering Customers
Your monthly WAPDA electricity bill displays two distinct sets of registers:
- Import Registers (1.8.0 / 1.8.1 / 1.8.2): Total electricity drawn from WAPDA grid during night and cloudy periods.
- Export Registers (2.8.0 / 2.8.1 / 2.8.2): Total surplus solar energy injected back into the grid.
- Net Calculation: If Export > Import, you receive a negative unit balance and a monetary credit to offset fixed meter charges, TV fees, and upcoming winter bills.
3. Common Causes of DISCO Application Delay & Solutions
Avoid common roadblocks:
- Transformer Saturation: Apply early before neighborhood transformer quota fills up.
- Unpaid Arrears: Clear all previous month utility bills before submitting application Form-I.
- Inconsistent Name on Title Deed: Ensure electricity bill connection name matches the property ownership documents or obtain tenant NOC.
Frequently Asked Questions
How does WAPDA calculate net metering units on monthly bills?
WAPDA deducts total exported units (Peak/Off-Peak separately) from imported units. Net off-peak imported units are charged at standard tariffs, while excess exported units roll forward as bill credits.
Can exported units offset WAPDA peak hour units?
No, WAPDA rules do not allow exported daytime solar units to offset evening peak hour consumed units. Peak units are billed in full.
What is the 80% transformer capacity rule in WAPDA DISCOs?
DISCOs cannot sanction total cumulative solar net-metered connections exceeding 80% of the rating of your neighborhood distribution transformer (PMT).
