Wildlife is unexpected factor causing power outages

Animal carcasses found near electrical installation after power trip incidents were reported.

KUCHING, Apr 15: Wildlife disturbances contribute significantly to the number of power supply trips in rural areas.

In a statement today, Sarawak Energy said since January this year, Sarawak Energy’s Central Region along covering Sibu and its surrounding areas have recorded 19 cases of wildlife presence on powerlines. Customers in Mukah, Dalat, Matu, Bintangor and Sarikei have experienced outages as a result of this unique factor.

“Disturbance caused by wildlife is one of the challenges faced by our operations team when serving the rural areas and the interior. While we can immediately deploy a technical team to restore supply to our customers after a tripping incident, it is unfortunate to see these animals electrocuted by the high voltage.

“We are looking into ways to mitigate the situation including changing from bare conductors to covered conductors, but this will be carried out in phases. This will reduce animal-related outage incidents and is also a sustainable approach to wildlife management in these areas,” said Yusri Safri, Sarawak Energy Vice-President for Distribution.

On Mar 30, customers in Dalat and parts of Judan experienced a power interruption at 12.48 pm. The technical team traced the source of the problem to an electrocuted monkey when they found its body on one of the power poles. Supply to the affected area was fully restored at 1.34 pm.


On Mar 27 at about 6 pm, a troop of monkeys perching on high voltage overhead lines of Matu-Daro also caused a power interruption affecting supply to villages in the area.

About 1,100 customers in Kampung Tian, Kampung Berjaya, Kampung Sekaan Kecil, Kampung Sekaan Besar, Matu Bazaar, Kampung Sok and Kampung Jemoreng were affected. Power supply to the affected areas was fully restored twenty at 6.18 pm, about 20 minutes later.

Yusri explained that before a line is re-energised, the technical team needs to patrol the affected lines to ensure all safety precautions are considered, which includes the possibility of fallen lines or poles along the stretch.

“It is our responsibility to ensure the safety of everyone near our electrical facilities and we take this very seriously. For longer overhead lines, it might take some time to patrol especially when it happens at night, under extreme weather or areas with difficult terrain.

“I hope customers can understand the challenges we faced. Nevertheless, we are still committed to do our best to minimise the interruption time,” assured Yusri.

Sarawak Energy said its operations arm remains vigilant in caring for the condition of its electricity infrastructure and equipment with timely scheduled maintenance works to ensure continuous and reliable power supply for rural areas.

“However, to reach households across the state, Sarawak’s transmission and distribution powerlines run a great distance alongside or through forests, farms and plantations. This has brought about a different challenge caused by wildlife,” said Sarawak Energy.
