The Hormuz Crisis: A Looming Threat to Taiwan's Power Grid and Global Energy Transition
The ongoing crisis in the Strait of Hormuz has sent shockwaves through Taiwan's energy sector, highlighting the delicate balance between energy security and the pursuit of a cleaner, more sustainable future. As the island grapples with the sudden loss of natural gas imports from the Gulf region, it finds itself at a critical juncture, where every decision has far-reaching implications for its power grid and the broader global energy landscape.
The Gulf Connection: A Strategic Partnership in Peril
Taiwan's reliance on imported natural gas, particularly from the Gulf region, has long been a strategic move towards energy diversification. In 2025, the island received a significant portion of its 23.6 Mt of LNG imports from Qatar and the UAE, with Qatar alone accounting for almost 8 Mt. However, the Hormuz crisis has exposed the vulnerability of this partnership. With Qatar's gas production halted and the Strait of Hormuz blocked, Taiwan's LNG supply from these key sources has been cut off, leaving a gaping hole in its energy strategy.
The Emergency Buffer: A Costly and Unstable Solution
In response, Taiwan has turned to the US as an emergency buffer, with American LNG deliveries rising from 200,000 t in March to 700,000 t in April, the largest monthly volume in Taiwan's history. While this provides a temporary solution, it is far from a stable, long-term fix. The US LNG is more expensive and less reliable than the Qatari volumes, which were treated as part of Taiwan's baseload procurement. This shift towards emergency cargoes underscores the fragility of the current energy landscape.
The Australian Pivot: A Limited Backup
Australia, another major LNG supplier, has been a stable pillar for Taiwan, with contract-secured imports of almost 8 Mt in 2025. However, Australia is also facing domestic gas-availability pressures, with a rule requiring 20% of LNG export volumes to stay in the domestic market from 2027. While existing Taiwanese contracts are expected to be honoured, any near-term increase in Australian supply is uncertain, leaving Taiwan with a limited backup plan.
Rebalancing Act: A Complex Strategy
Taiwan's state-owned oil and gas company, CPC, is already attempting to rebalance its energy portfolio. Chairman Fang Jeng-zen has outlined a strategy to reduce dependence on Middle Eastern LNG, with a new US contract bringing an additional 1.2 Mt annually. However, this is a medium-term fix, and the immediate challenge lies in replacing the lost Gulf cargoes. Russian LNG, once a stable option, is now politically constrained, leaving Taiwan with limited alternatives.
The Power-Market Exposure: A Delicate Balance
Taiwan's power-market structure, with government-owned Taipower controlling around 66% of generation, is not immune to the crisis. Gas-fired plants, which generate around 50% of the island's electricity, are directly affected by the LNG shortage. If the lost Qatari and UAE cargoes are not replaced, Taiwan could face a significant loss of gas-fired power generation, potentially impacting more than 10% of its monthly demand. This raises uncomfortable questions about power prioritization, especially during the seasonal rise in electricity consumption from June to September.
The Coal Fallback: A Temporary Solution with Long-Term Implications
Coal, traditionally phased out in favour of natural gas, emerges as a short-term fallback. Taiwan's coal-fired generation now accounts for around 35% of its power output, and four units at the Hsinda coal plant have been moved into emergency back-up status. While this helps offset the gas loss, it covers only about half of the potential gap. Moreover, coal is not without its own challenges, with Taiwan competing for limited Australian coal supplies and facing rising prices.
The Spot Market: A New Reality for Taiwan
The crisis has forced Taiwan deeper into the spot LNG market, where every other Asian importer is also trying to insure itself against the shortage. Landed Taiwan LNG prices have soared to around $17/MMBtu, with little prospect of quick relief. This shift has implications for Taiwan's energy transition, as it leans more heavily on spot purchases, potentially impacting its long-term energy strategy.
Nuclear Power: A Strategic Fix in the Future
Nuclear power, once a strategic fix for Taiwan's energy problems, is now stuck in the future. While Taipower has submitted a plan to restart Kuosheng and Maanshan nuclear plants, the full restart is unrealistic before 2028, leaving it irrelevant for the immediate summer squeeze. This highlights the challenges of balancing energy security with the pursuit of cleaner, more sustainable options.
The Broader Implications: Power Rationing and Global Supply Chains
The Hormuz crisis extends beyond Taiwan's borders, raising concerns about power rationing in an economy built on semiconductor and photovoltaic manufacturing. These sectors, crucial for the global transition to cleaner energy, could suffer first if shortages hit in earnest. This scenario underscores the interconnectedness of global energy markets and the potential for a major semiconductor supply crisis.
A Call for Resilience and Innovation
In the face of this crisis, Taiwan's energy transition is being tested. The island must navigate a fragile bridge, balancing emergency solutions with long-term strategies. While the immediate challenges are clear, the crisis also presents an opportunity for resilience and innovation. By embracing a more diverse and flexible energy portfolio, Taiwan can emerge stronger, ensuring a more secure and sustainable future for its power grid and the global energy transition.
