Taiwan imports almost all of its primary energy by sea, with liquefied natural gas the most time-critical component because it cannot be stored long. That dependence is the island's most structurally significant vulnerability and it exists continuously, not only in a contingency.
This is the clearest case in the module of a dependence that is a present structural fact rather than a contingency. It shapes Taiwan's energy policy, its industrial competitiveness and the semiconductor cluster's operating costs continuously; and because electricity generation depends on it, a sustained interruption would reach chip fabrication — the point at which Taiwan's domestic vulnerability becomes a global economic exposure. It is also why any coercive scenario discussed publicly concerns interdiction of shipping rather than of territory.

- 概覽
- Taiwan has almost no domestic fossil-fuel production and imports essentially all of its coal, oil and natural gas. Energy policy through 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 rather than on stored fuel. Natural gas supplied roughly 48 per cent of generation in 2025 and coal about 35, against a stated target of 50 and 30, with renewables at about 13 against a 20 per cent target. The reserves behind that mix differ by an order of magnitude and are not interchangeable. Gas is the binding case: it is stored as a cryogenic liquid, boils off over time and cannot be warehoused the way coal or crude can, and the security-stockpile requirement placed on importers is 11 days, stepping to 14 by 2027, with a parallel storage-capacity requirement rising to 24 days. Coal is held to around 30 days, with the state utility reporting holdings above that. Oil carries a 90-day statutory reserve split between government and industry. A single "days of energy" figure would obscure all of this, because the fuels serve different plant and cannot be substituted on the timescale of a disruption.
- 依賴它的事物
- Near-total for primary energy and structurally unfixable in the short term. There is no domestic substitute at scale, no pipeline connection to anywhere, and no land route. The one genuine lever is the generation mix — the balance between gas, coal, nuclear and renewables changes how much of the system's cover sits in the short-duration fuel — and that is a contested domestic political question rather than a technical one. It is currently being contested through two tracks at once: Taipower filed reactivation plans for two plants with the Nuclear Safety Commission in March 2026, with review estimated at 18 to 24 months, while the Legislative Yuan approved a further referendum proposal in August 2026. Neither track has restored any generation, and on the published regulatory timeline none is possible before roughly 2028.
- 中斷造成的影響
- A sustained interruption would reach electricity generation first and industrial output immediately after, with semiconductor fabrication among the most sensitive loads because it cannot be interrupted cleanly. Because the cluster supplies most of the world's advanced chips, the consequence would not stay local. Short interruptions are absorbed by reserves; the system's character is that its tolerance differs by fuel — roughly a fortnight of gas against a quarter of oil — and that the fuel with the shortest cover is also the largest share of generation.
- 替代方案與冗餘
- Limited and slow. Cargo can approach from the north, south or east rather than through a single route, and that routing redundancy is real. What has no substitute is arrival by sea itself, and no change to the generation mix can be made on the timescale of a disruption — reserve levels and the nuclear question are decisions taken years ahead. The honest statement is that Taiwan's energy security is a policy problem in peacetime and not a solvable logistics problem in any other condition.
節點
依此紀錄撰寫時的順序排列 — 這是撰寫的次序，而非路線。
臺灣最大的港口與南部主要工業城市 — 該島的主要貨櫃門戶，也是其貿易依賴具體化的地點。
In this systemTaiwan's principal southern port and the largest single maritime gateway for bulk imports.
Why it mattersTaiwan's economy is an import-and-export system running through a small number of large ports, and Kaohsiung is the largest. Its significance in this module is economic continuity: container throughput, energy imports and the shipping links any maritime disruption would affect first. It also sits nearest the southern approaches, where the Bashi Channel connects the strait to the open Pacific.
What to watchContainer throughput and shipping-line routing decisions; energy import handling; war-risk insurance pricing affecting calls at Taiwanese ports.

服務臺北都會區的北部港口，位於島嶼東北端海峽與東海交會處。
In this systemThe northern port serving the Taipei region.
Why it mattersKeelung is the northern half of Taiwan's port system and the point where the island's trade geography connects to the northern approaches. Its relevance here is continuity of northern maritime access, and its proximity to the East China Sea context that draws Japan into the system.
What to watchNorthern shipping continuity and routing; port throughput as an economic indicator.

Taiwan's second city and a central node in the semiconductor manufacturing corridor, hosting advanced fabrication capacity alongside heavy industry and one of the island's largest power-generating concentrations.
In this systemCentral-west coast, and one of the island's major industrial and import nodes.
Why it mattersTaichung shows how tightly Taiwan's chip industry and its energy system are coupled: advanced fabrication is enormously power-intensive and intolerant of interruption, and it sits in the same region as major generation. That coupling is why energy resilience is an economic-security question here, not only a civil one.
What to watchAdvanced-node capacity decisions; grid resilience and generation policy affecting the manufacturing corridor.
工業中心 信心：中等 截至2026-07 在地圖上顯示 →
The body of water separating Taiwan from mainland China — roughly 130km wide at its narrowest — and one of the most heavily transited stretches of sea in the world.
In this systemThe western approach through which a large share of arriving traffic passes.
Why it mattersThe strait is the physical centre of the system and the reason it has global weight. A very large share of world container traffic and a substantial share of LNG bound for Northeast Asia passes through or near it, which means disruption here would be an economic event for countries with no stake in the dispute. Running down the middle is the median line: an unwritten restraint observed for roughly half a century, and effectively abandoned as a limit after August 2022. Its erosion is the single clearest measure of how grey-zone pressure works — nothing was announced, and nothing was given back.
What to watchOfficially reported trends in air and naval activity across the strait; shipping routing and war-risk insurance pricing; any shift toward inspection, quarantine or customs-enforcement language in official statements.

臺灣南部與菲律賓北部巴丹群島之間的水域——較廣闊之呂宋海峽的北段，也是南海與菲律賓海之間最直接的海上門戶。
In this systemThe southern approach from the South China Sea and the Pacific.
Why it mattersThe Bashi Channel is where Taiwan's geography stops being a bilateral question. It is a principal route between the South China Sea and the open Pacific, carrying commercial traffic and undersea cables, and it is the reason the Philippines is part of this system whether or not Manila wishes to be. Its narrowness relative to the ocean either side is what gives the phrase "maritime access" concrete meaning here.
What to watchShipping and cable continuity through the channel; regional exercise activity and access arrangements in northern Luzon; any assertion of jurisdiction over waters in the area.

A northeastern coastal port on Taiwan's Pacific side, included here as an east-coast maritime node rather than for any facility detail.
In this systemNorth-eastern port, and the clearest eastern-side maritime access point.
Why it mattersTaiwan's east coast faces the Philippine Sea rather than the strait, which gives the eastern seaboard a different strategic character: it is the side facing open ocean and deeper water. Suao marks that transition on the northeast, where the island's geography turns from strait to Pacific.
What to watchEast-coast maritime access as a general indicator; communications and cable routing on the Pacific side.

Island-wide power failures caused by domestic grid faults rather than by any external factor, which nonetheless demonstrated how little margin the system holds and drove public debate about reserves and the generation mix.
Undersea cable damage affecting communications rather than energy, recorded here because it demonstrated the same structural point about maritime infrastructure dependence and because attribution was contested in both cases.
政治意涵
The generation mix, and particularly the nuclear question, is one of Taiwan's most contested domestic policy debates, and it is a security question whether or not it is framed as one.
軍事意涵
Explains why publicly discussed coercive options concern maritime interdiction rather than territory.
經濟意涵
Sets Taiwan's industrial energy costs continuously and is the physical basis of the semiconductor exposure the economy section describes.

仍然未知的事項
- Reserve levels by fuel are published as targets and aggregates rather than as current holdings; actual cover on any given date is not public.
- Terminal and storage detail is deliberately not published by this module and is not the basis of any claim here.
- Attribution for the cable incidents has not been established, and this record treats them as demonstrations of structural dependence rather than as coercion.
證據同樣支持的其他解讀
- Taiwan's shift toward LNG can be read as an energy-transition choice that incidentally increased strategic exposure, or as a decision taken with that exposure understood and accepted. Both are argued domestically, and the policy record supports each in part.
- The 2021–2022 outages can be read as evidence of thin margins or as ordinary grid faults of the kind that occur in many advanced economies. The distinction matters for how much they say about resilience under pressure.
