The 1996 Peninsular Malaysia electricity blackout crisis was a power outage in Malaysia. It occurred at 17:17 on 3 August 1996. The whole of Peninsular Malaysia including Kuala Lumpur, Selangor, Putrajaya, Johor, Malacca  and Negri Sembilan plunged into darkness for several hours.

A transmission line near Sultan Ismail Power Station in Paka, Terengganu tripped at 5:17pm causing all power stations in Peninsular Malaysia to collapse resulting in a massive power failure. Supply was back to normal by 11pm.[1]
