On 13 January 2005 a power blackout on northern peninsular Malaysia occurred when a transmission line near Serendah, Selangor, had broken down. In response to this, the Central Area Reinforcement (CAR) project was approved to ensure security of power supply to the Klang Valley. On 22 April 2008 Sabah had the worst power outage since the commissioning of the east west power grid. Suspected vandals are believed to have removed steel pieces of a 132kV transmission tower that led to its collapse, triggering a major power blackout. An emergency temporary tower was to be built immediately but it also collapsed during construction killing a TNB personnel. On 1 May 2008, another tower collapsed due to missing structural members of the tower that were suspected of being stolen.
