Transmission Line Works To Connect The Mapai Substation To Tondong Substation Portion Of 500kv Transmission Line Grid For Better Supply Reliability



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.

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 improve 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 9 – 28 December 2022. A critical part of the line re-organisation is expected to be performed from 18 – 28 December 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.
