A major power-outage affected regions of Taiwan with semiconductor manufacturing bases, earlier this morning (March 3, 2022). A malfunction with a power-station caused a sudden drop in power-generation, triggering power-grid failures, and resulting in blackouts lasting around 90 minutes. This may not seem like much, but for a semiconductor manufacturing facility with limited power back-up and time-critical and power-critical processes, 90 minutes is an eternity.

Taiwan News reports that a Taipower plant in Kaohsiung suffered a malfunction with steam leaks in the turbine room, triggering an emergency shutdown. This caused a 10.5 MW drop in supply. Such sudden supply-demand changes can cause AC frequency to fall out of the safe range, and transmission equipment in switch-yards are designed to automatically trip (to protect end-user equipment). A cascading power outage was seen in Wenshan District, Neihu District, Da'an District, and Xinyi District. In New Taipei City, Yonghe District, Banqiao District, and New Taipei Industrial Park. Various semiconductor-manufacturing companies are yet to report how this power-loss affected them.
