PETALING JAYA (THE STAR/ASIA NEWS NETWORK) – Power has been fully restored to all regions of Malaysia that were earlier on Wednesday (July 27) hit by widespread blackouts.

National utility company Tenaga Nasional Berhad (TNB) said power was restored to all affected regions by 3.02pm, about three hours after reports started streaming in of power outages at several places in some states.

“The power supply to most areas was restored in stages 20 minutes after the disruption due to the continuous work of the TNB technical teams,” it said in a statement.

TNB said the source of the disruption that began at 12.39pm was traced to a fire at Yong Peng intake station in Johor.

This had resulted in load shedding of 2.2GW, which amounted to 10 per cent of the total supply demand in Peninsular Malaysia.

Media reports said parts of Malaysia including Penang, Pahang, Negeri Sembilan and the Klang Valley experienced power disruptions. 

The Klang Valley encompasses the capital Kuala Lumpur and surrounding districts in Selangor state. Places that had reported confirmed blackouts included Bangsar, Cheras and Shah Alam.

Malaysians took to Twitter to complain about the electricity cut, with some mentioning places in Negeri Sembilan and Perak as also experiencing the same.

Other states that reported electricity outage include parts of Penang and Pahang but supply was restored less than an hour after it was reported.

On Twitter, #Blackout was one of the top trending topics, with more than 4,000 tweets by users sharing their experiences.

In Kuala Lumpur, the blackout caused many traffic lights in the city to malfunction.

It also affected the main terminal of Kuala Lumpur International Airport (KLIA).

In a post on Twitter, the airport said: “We are sorry that KLIA main terminal building is currently experiencing power supply interruption. Our engineering team is communicating closely with TNB to resolve the matter.”

About an hour later, the airport tweeted that power supply has been restored.

Public transport service provider RapidKL, which operates the LRT, MRT and Monorail rail services, said its services were also affected by the power disruption.
