As tensions escalate in the Taiwan Strait, officials in Taipei are intensifying efforts to ensure the island can sustain critical fuel and supply flows amid growing concerns of a Chinese blockade. China, which asserts sovereignty over Taiwan, has increasingly conducted naval exercises simulating a cohesive blocking strategy, deploying ships and aircraft to disrupt external access.
Taiwan’s dependence on imported fossil fuels, with natural gas alone accounting for nearly half of its electricity production, has left it particularly vulnerable to supply disruptions. Recent global crises—such as the Gulf of Hormuz blockades during regional conflicts—have underscored the urgency of diversifying energy sources and securing resilient transport routes.
To address these risks, Taiwanese authorities are evaluating innovative solutions, including offshore floating natural gas storage units, strategic stockpiles capable of supporting months of demand, and the potential reactivation of idle nuclear power plants. Officials have engaged in tabletop simulations to model responses to a blockade scenario, with planned drills focused on ship escort operations, logistical redirection, and distribution of essentials like fuel and food, according to four individuals involved in the planning.
Mitigating Power Sector Challenges
Ensuring power plant functionality during a blockade presents formidable challenges. At present, Taiwan holds 11 days of natural gas reserves and could expand storage capacity to cover up to 20 days. This buffer remains precarious, as nearly all liquefied natural gas (LNG) terminals are concentrated along the west coast, which could become a primary target during hostilities. Eastern regions, though more remote, lack compatible infrastructure to manage LNG deliveries or integrate the fuel into the grid.
Chen Chung-hsien, Deputy Director-General of Taiwan’s Energy Administration, emphasized proactive preparedness, stating Taiwan conducts ongoing exercises to address worst-case scenarios. Proposals include deploying offshore “floating” LNG processing platforms to diversify ingress points and reduce vulnerability, according to Chen Kuan-ting, a legislator aligned with the ruling Democratic Progressive Party. “Flexible energy reception capabilities are vital for maintaining grid stability if the west coast becomes inaccessible,” he noted.
Coastal Vulnerabilities and Strategic Posturing
China’s recent deployment of larger coast guard vessels to Taiwan’s eastern waters—under formal maritime safety mandates—has heightened anxieties over “gray zone” tactics. These operations, blending law enforcement and military-style maneuvers, have included intercepting cargo ships to demand crew details and shipping manifests. Experts characterize this as a precursor to broader coercion, with Beijing testing Taiwan’s willingness to challenge its authority in contested zones.
During a simulated blockade scenario in June 2024, Taiwanese President Lai Ching-te’s administration rehearsed procedures for verifying the legitimacy of incoming vessels and managing emergency disembarkations, highlighting disputes over jurisdictional claims. The Lia Ministry reported planning September drills on the east coast to test coordination between disaster response networks, logistics teams, and the military. Collaboration across agencies—including economic affairs and agriculture—will be critical to executing supply chains during crises.
Evolving Chinese Maritime Assertions
Chinese threats have intensified following the 2024 decision to station its largest coastal enforcement ships near eastern Taiwan—a strategic pivot from patrolling the island’s eastern approach routes, which could threaten Taiwan’s fuel supply line from the Pacific. Though currently largely symbolic, analysts warn these vessels could escalate to detaining goods without immediate military involvement. Taiwanese officials project heightened activity ahead of its 2028 presidential elections, which China may leverage as a pretext to amplify pressure.
The recent surge in the frequency of China’s maritime vessels—85 instances in May-June 2024 versus 45 the prior year—reflects Beijing’s growing confidence in forming layered deterrence strategies. These measures are increasingly integrated into formal military exercises, experts note, signaling a shift toward institutionalizing non-kinetic coercion as a tool to isolate Taiwan economically. The next phase, experts argue, could involve outright seizure of vessels if jurisdictional disputes escalate, further complicating Taiwan’s response protocols.
