電力系統可靠度資料統計

系統平均停電時間SAIDI(System Average Interruption Duration Index)及系統平均停電次數SAIFI(System Average Interruption Frequency Index,SAIFI)係國際電業常用來衡量供電可靠度的指標，其數值越低越好。台電公司為我國唯一輸電業，在國內並無同級民營業者可比較，爰經濟部能源署整理我國及各國SAIDI與SAIFI數值，讓大家對電力系統可靠度有更深一層的了解與認知。

The System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI), which are commonly used in the international electricity industry to measure the reliability of electricity supply, are indicators where lower values are preferable. As the sole transmission utility company in our country, with no comparable private sector counterparts, the Ministry of Economic Affairs' Energy Bureau has compiled the SAIDI and SAIFI values of our country and various other countries to provide a deeper understanding and awareness of the reliability of the electricity system.
