LESCO distributes electricity across Lahore, Kasur, Sheikhupura, Okara, and Nankana Sahib, the most populous load centre in Punjab.
Lahore carries one of the highest connection densities in the country, and that weight shows on every LESCO bill. The city feeder network threads through commercial corridors along Ferozepur Road and the Ring Road, dense housing societies, and the industrial clusters at Kot Lakhpat and Sundar. Move outward to Kasur, Okara and Nankana Sahib and the character of demand shifts from air conditioners and commercial lighting to tube-well pumps and grain processing. For a residential consumer in Gulberg, the biggest bill shock comes in June and July when cooling pushes units into a higher slab band. For an Okara farmer, it arrives in the pre-monsoon irrigation months. Your LESCO reference number identifies your specific meter, not your address, so the same 14-digit code works every time you check the bill regardless of which month you are looking up.
Your LESCO reference number is the 14-digit code printed near the top right of any previous bill. It belongs to the meter, not the billing period, which means you can use a bill from several months ago to pull today's charges. The lookup goes straight to the PITC system LESCO issues bills through, so the duplicate you see is the same official document your bank and housing society will accept. Lahore consumers check bills most frequently in June and July when cooling pushes units into a higher slab, and again in January when geyser and heater use adds to the winter load.
