A landslide triggered by continuous heavy rainfall on 12 May 2025 caused major damage to the 66/11 kV power sub-station at Sichey, affecting power supply in nearby areas.

According to the Power Department, the landslide occurred around 6:30 PM, severely damaging the 11 kV control room and feeder panels. Sludge and water entered the control room, damaging electrical equipment, the battery system, and building columns.

As a result, electricity supply to Lower Sichey and Ranka has been disrupted. Restoration work is underway, with officials and staff from the department working continuously. However, due to the severity of the damage, full restoration may take several days.
