Taiwan imports almost all of its primary energy by sea, with the fuel that carries the largest share of generation also holding the shortest reserve. The dependence and its effect on generation are documented present facts; what an interruption would do to output is an unconfirmed scenario.
為地緣政治風險與經濟曝險工作撰寫：它追溯的是一項機制，而非市場觀點。
如何解讀等級
- 已證實 有來源記錄其已經發生。
- 合理可信的曝險 Vigil評估為很可能的機制；尚無其已經發生的紀錄。
- 未經證實的情境 因為值得觀察而列出。並非斷言。
一個步驟的等級永遠不能高於它所依賴的步驟：結果的確立程度不能高於其原因。這項規則在本網站建置時強制執行，而非以人工套用 — 違反它的鏈會導致建置失敗，而不會被發布。
- 觸發因素
一座沒有管線或陸地連結的島嶼幾乎完全依賴能源進口，再加上發電結構偏重一種無法長期儲存的燃料
- 受影響的資產、路線或地區已證實
Taiwan imports roughly ninety-six to ninety-seven per cent of its primary energy. There is no domestic production at scale, no pipeline connection and no land route. Energy policy over the last decade shifted generation toward liquefied natural gas while nuclear output fell to zero — the last operating reactor shut down in May 2025 — which raised the share of the mix depending on a continuous stream of arriving cargoes. Gas supplied about 48 per cent of generation in 2025 and coal about 35. The reserves behind them are not one number and not interchangeable: the gas security stockpile is an 11-day requirement stepping to 14 by 2027, coal is held to around 30 days, and oil carries a 90-day statutory reserve. Gas is the binding case because it is both the largest share and the shortest cover — it boils off and cannot be warehoused the way coal or crude can. The adequacy of those targets is a live public argument.

- 營運中斷已證實
The system has already demonstrated thin margins for reasons unrelated to the strait. Island-wide power failures in 2021 and 2022 arose from domestic grid faults and prompted a substantial public commitment to grid hardening and resilience. Those events are the available evidence about how the system behaves under stress, and their causes were entirely internal.

- 曝險的產業或商品已證實
Electricity generation is the transmission point between fuel arrival and the real economy. Industrial output is capped by available power, and semiconductor fabrication is among the least interruptible loads on the island — a fabrication process cannot be stopped and restarted cleanly. That connects the energy dependence directly to the cluster whose output the rest of the world depends on, which is the specific reason this is an international exposure rather than a domestic Taiwanese one.

- 更廣泛的經濟意義未經證實的情境
What an interruption to arriving energy would do is not documented and Vigil does not assert it. Named as worth watching rather than asserted: the 2021–2022 outages were grid faults rather than supply failures, so they show how the system behaves when generation is lost and not how it behaves when fuel stops arriving, which are different problems. The firmer observations are that the binding constraint is the eleven-day gas stockpile rather than the ninety-day oil reserve, that no policy lever changes that on the timescale of a disruption, and that the generation mix — the one real lever — moves on an electoral rather than a strategic timetable. Vigil publishes no estimate of tolerance, duration or output effect.

曝險的產業與商品
以一般標籤命名，而非受控詞彙，因此這份清單不會與本模組經濟部分已使用的商品名稱產生偏差。
仍然未知的事項
- Reserve levels by fuel are published as targets and aggregates rather than as current holdings, so actual tolerance on any date is not knowable.
- The 2021–2022 outages were grid faults rather than supply interruptions and do not support inference about the latter — which is why the final step is graded as an unconfirmed scenario.
- Terminal, storage and grid detail is deliberately not published by this module and is not the basis of any claim here.
- Vigil publishes no estimate of interruption tolerance, duration or output effect, and the absence is deliberate.
證據同樣支持的其他解讀
- The shift toward LNG can be read as an energy-transition choice that incidentally raised strategic exposure, or as a decision taken with that exposure understood and accepted as a cost. Both are argued in Taiwan's own politics and the policy record supports each in part.
- The 2021–2022 outages can be read as evidence of thin margins under any stress, or as ordinary grid faults of a kind that occur in many advanced economies with no strategic implication. The reading determines how much they say about resilience.

A large commitment was made after the outages. Delivery against it is observable and lags the announcement.
