Winter Electricity Maintenance and Power Outage Schedule in Pakistan (2026-27): Consumer Guide

Power distribution companies across Pakistan, including the Islamabad Electric Supply Company (IESCO), LESCO, and FESCO, have officially launched their annual winter grid maintenance and system enhancement drives for the 2026–2027 season. Running annually from October through February, these scheduled shut-downs are essential for upgrading high-voltage transmission lines, replacing aging transformers, and pruning tree branches near overhead power distribution lines to maintain grid stability.

Maintenance Scope Across IESCO Grid Stations and Feeders

During the winter cycle, distribution utilities carry out comprehensive technical overhauls across more than 130 grid stations and over 1,295 operational feeders. Because overall electricity demand drops significantly during cooler months due to reduced air conditioning loads, engineers utilize this low-demand window to conduct critical transformer servicing, line clearing, and circuit breaker replacements to prevent catastrophic equipment failures during peak summer months.

How Consumers Can Check Advance Power Outage Schedules

Power companies issue daily and weekly temporary shutdown notifications to minimize inconvenience for residential, commercial, and industrial consumers. Subscriptions and schedules are accessible via official DISCO websites, SMS alert systems, mobile customer service apps, and official social media channels. Shutdowns are typically scheduled during daylight hours, between 8:00 AM and 4:00 PM, on designated weekdays for specific feeder circles.

Consumer Guidelines and Winter Energy Management Tips

To prevent appliance damage caused by voltage fluctuations during scheduled restoration periods, consumers are advised to unplug sensitive electronic devices prior to announced shutdown windows. Additionally, power authorities encourage households to practice energy-efficient habits, inspect domestic electrical wiring, and report localized line faults or broken wires immediately through central company helplines or the national 118 power complaint hotline.
