KUCHING, Dec 5: Transmission line connection works are commencing soon to connect the Mapai Substation to Tondong Substation, part of the 500KV Transmission Grid, Sarawak’s second transmission backbone.

According to a press statement from Sarawak Energy Berhad, overall electricity supply is expected to be unaffected during the duration of the connection works.

Nevertheless, preparations are being done to ensure safe completion of works in the shortest time possible. In the event of bad weather, works may be postponed for safety reasons.


This will be a third point of injection into the southern (Kuching) grid system and further improves reliability of the grid system and overall power supply to Kuching City.

Prior to the commissioning, a scheduled shut down and re-organisation of the existing Engkilili-Entinggan Transmission Line will be performed from December 9-28, 2022.

A critical part of the line re-organisation is expected to be performed from December 18-28, 2022.

Members of the public can contact Sarawak Energy Customer Care Centre at 1300-88-3111, or utilise Sarawak Energy’s mobile app SEB Cares to obtain the latest updates of the connection works or report outages to assist in the speedy restoration of electricity supply. — DayakDaily
