KUALA LUMPUR, July 27 – Tenaga Nasional Berhad (TNB) has managed to fully restore electricity supply to all areas experiencing power outages at 3:02pm. Most of the affected areas were successfully restored in stages as early as 20 minutes after the disruption occurred as a result of the continuous efforts of the TNB Technical Team said TNB in a Facebook Post.
TNB’s investigation found that the supply disruption that started at 12:39 this afternoon was caused by a fault in one of the equipment at the Main Entrance Substation (PMU) Yong Peng North in Yong Peng, Johor. It has resulted in load shedding of 2.2GW which is 10% of the total supply demand in Peninsular Malaysia.
Earlier today several areas in Peninsular Malaysia are experiencing power outages since 12:39 this afternoon involving 10% of the entire supply demand. Among the areas involved are in Petaling Jaya, Cheras, Bangi, Bayan Lepas, Seberang Jaya, Panchor and Bandar Indera Mahkota.
The supply was fully restored within 20 to 40 minutes in all affected areas except for the affected areas in the Kelang Valley and the cause of the incident is being identified and efforts are underway to restore the supply said TNB in the Facebook Post.
