KUALA LUMPUR — Malaysia’s national electricity provider Tenaga Nasional Berhad (TNB) has confirmed that power is now fully restored to all areas in the country hit by disruptions at around noon on Wednesday (July 27).

In a statement, TNB said that most of the affected areas saw their electricity successfully restored in stages as early as 20 minutes after the disruption occurred, as a result of the continuous efforts of its technical team.

It said the issue was fully rectified at 3.02pm.

“TNB’s investigation found that the supply disruption that started at 12:39pm this afternoon was caused by a fault in one of the equipment at the Main Entrance Substation (PMU) Yong Peng Utara in Yong Peng, Johor.

“It resulted in load shedding of 2.2GW which is 10 per cent of the total supply demand in Peninsular Malaysia,” it said.

Earlier on Wednesday, Malaysian media reported that several parts of Peninsula Malaysia, especially the Klang Valley, had been facing power disruption, which also interrupted rail services, airports and traffic lights.

According to complaints by Internet users, the affected areas in the Klang Valley were in Petaling Jaya, Shah Alam, Bangi, Selayang, Cheras and Bandar Sunway.

It is believed that the blackout was caused by a heavy thunderstorm that hit the area earlier on Wednesday.

Blackouts were also reported in Kedah, Pahang, Negri Sembilan, Perak and Penang. AGENCIES
