Instead, there's been a problem with the cables at a power plant in southern Taiwan. Because the margin reserve (the amount of power that can be produced by generator sets kept in reserve) is limited, there is no power available to fill the gap.
這不是颱風、地震，而是台電南部電廠發生線路故障，備載容量（備用發電機組可發電量）又有限，沒有足夠電力接檔上手。
