What is a Protected Consumer in Pakistan electricity tariffs?

A residential consumer is designated as "Protected" if their electricity consumption has remained 200 units or less per month for the past 6 consecutive billing cycles. Protected consumers enjoy subsidized lifeline tariffs (Rs. 3.95 to Rs. 14.16/unit). Exceeding 200 units even once immediately moves you to the unprotected higher slabs (Rs. 16.48 to Rs. 42.72/unit).

How does solar net-metering credit calculation work on WAPDA bills?

Bi-directional green meters export excess daytime solar electricity to the DISCO grid (LESCO, IESCO, MEPCO, KE). Billed units are calculated as Net Units = Imported kWh - Exported kWh. Any surplus units exported over consumption are credited at NEPRA buyback rates (~Rs. 24.50/unit) to offset future bills or generate financial credits.

What additional taxes and surcharges are included in WAPDA electricity bills?

Pakistani electricity bills include Fuel Price Adjustment (FPA), Financing Cost (FC) Surcharge (Rs. 3.23/kWh), Electricity Duty (1.5%), General Sales Tax (18% GST), TV/Radio Fee (Rs. 35), and Advance Income Tax under Section 235 (7.5% for non-filers on bills over Rs. 25,000).

Frequently Asked Questions

Common questions and answers about Electricity Bill & Solar Net-Metering Estimator.

Electricity units (kWh) are calculated by subtracting your Previous Meter Reading from your Current Meter Reading on your DISCO bill. For three-phase Time-of-Use (ToU) meters, Peak and Off-Peak units are recorded separately on different registers (01 and 02) and billed at their respective NEPRA slab rates.
