⚙️ Why This Maintenance & What You Should Do

The suspension is necessary to carry out various preventive and corrective maintenance works on the power distribution network. Such works often include repairs, line inspections, switching operations, or upgrades of transformers/cabling—steps crucial to reduce future disruptions and maintain grid reliability.

Residents in the listed areas should take the following precautions:

Charge essential devices (phones, power banks, laptops) in advance

Keep backup lighting (flashlights, emergency lamps) ready

Avoid scheduling critical work dependent on electricity (e.g., medical equipment, appliances) during the outage window

Unplug sensitive electronics to guard against voltage fluctuations when power is restored


Importantly, while the restoration is slated for before 2 p.m., completion depends on how smoothly the maintenance proceeds. Delays are possible if unexpected issues arise.
