In a statement, Wednesday, its Managing Director, Abd Razak Salim, said strong winds and heavy rain recently caused fallen trees and branches to sever supply lines while landslides have toppled electricity poles in several areas.
"The weather phenomenon has also damaged many SESB installations causing power interruptions," he said, adding that the number of SESB standby teams has been increased to expedite repairs and restoration of power supply in affected areas.
The teams are now on duty round-the-clock restoring electricity supply in affected areas.
He said SESB also has been receiving many calls from the public.
However, Abd Razak said where restoration of power is concerned, priority would be goven to critical places such as hospitals.
According to him, among areas that are facing an increase in power interruptions are Kota Kinabalu, Keningau, Tenom, Kudat and Labuan.
He encouraged the public to contact SESB's Hotline 15454 and 088-515000 in the event of power interruptions.
