Technical team from SEB passing through flood waters and muddy conditions to fix the damaged facility.

MIRI: Electricity supply to Marudi was restored by Sarawak Energy Berhad’s (SEB) technical team last Saturday.

More than two days of extensive repair works to replace snapped power lines, suspected to have been struck by lightning, on a 33kV high tension tower, were carried out.

Sesco Berhad CEO Lau Kim Swee said Sesco deeply regretted the inconvenience caused to residents, and thanked them for their patience.

“The team will continue to monitor the performance of the supply lines and will remain on standby until we are assured that the system has really stabilised.

“The replacement power lines were energised on July 4 around 6pm, and supply to the area progressively restored until stable supply reached all affected areas at 7.10pm. Repair works include replacing broken conductors and cracked insulators,” he said in a statement today.

Lau also stated that the team was glad that despite some difficult weather, water and terrain conditions, the team was able to restore supply safely.

“Safety is top priority for us at Sarawak Energy so the team was only allowed to start work after it is deemed safe.”

Prior to energisation of the lines, the majority of Marudi was provided with temporary electricity from 10 mobile generator sets.

According to Lau, following the interruption at 4pm last Thursday, SEB had intensified efforts to restore supply to the riverine town and its surrounding areas, increasing manpower resources and bringing in machinery.

“Recent heavy rainfall had caused flooding at the location of the tower and to perform repair works, the technical team had to wade through chest-high water levels of swamp and muddy terrain caused by a torrential thunderstorm before reaching the site around 4am on Friday (July 3), 12 hours after the outage occurred.

“We appreciate the team’s efforts in overcoming these challenges and doing the necessary rectification work to restore supply safely as soon as possible,” he continued.

Additionally, regular patrol works were done to inspect the 44km power lines that transmit electricity from Marudi Junction Substation to Marudi.

“The power lines traverse forested areas and also private oil palm plantation estates, obstructing smooth access in the event of a fault,” he concluded.
