Malaysia has experienced a series of significant power outages over the past three decades, caused by everything from lightning strikes to equipment failures. A 1992 lightning strike caused a total blackout, while a 1996 transmission line trip in Paka, Terengganu, triggered a massive collapse across Peninsular Malaysia, leading to a drop in Tenaga Nasional's stock and the entry of independent power producers. In 2003, a five-hour outage in the southern peninsular cost industries $13.8 million, and a 2005 fault near Serendah, Selangor, cut power to the northern states. More recently, on July 27, 2022, a faulty appliance at the Yong Peng North Main Entry Substation caused a widespread blackout affecting the Klang Valley, Pahang, and Negeri Sembilan, disrupting RapidKL trains, KLIA, and internet services, though power was largely restored within hours. The most recent major incident occurred on December 6, 2023, when the Sultan Iskandar Building checkpoint in Johor Bahru suffered an 11-hour outage after backup generators failed during maintenance, causing massive queues and manual immigration clearances, which Johor's Menteri Besar Onn Hafiz Ghazi called an embarrassment. These recurring events highlight the grid's vulnerability to both natural and technical failures, with significant impacts on transport, industry, and daily life.
