Taiwan’s final nuclear reactor shutdown sparks national debate over energy security as the island nation faces soaring costs, chip industry demands, and growing tensions with China.
At a Glance
- Taiwan is shutting down its last nuclear reactor, completing a decades-long phaseout strategy
- The move threatens Taiwan’s energy-intensive semiconductor industry as power demand is projected to rise 13% by decade’s end
- Each closed reactor increases annual LNG import costs by approximately $500 million, creating both economic and security vulnerabilities
- Public opinion is shifting, with growing support for nuclear energy and planned referendums on restarting nuclear plants
- Taiwan’s energy mix will be 84% fossil fuels following the reactor shutdown, challenging emissions reduction targets
The Path to Nuclear Phaseout
Taiwan’s journey away from nuclear power began dramatically in 1996 when residents of Orchid Island blocked a freighter carrying nuclear waste from docking. The protest, led predominantly by indigenous residents, marked a turning point in Taiwan’s energy policy. The nuclear waste shipment was forced to turn back, never reaching shore, in what became a defining moment for the country’s environmental movement and energy future. This grassroots resistance, combined with safety concerns following Japan’s 2011 Fukushima disaster, accelerated Taiwan’s commitment to phasing out nuclear power.
The shutdown of Taiwan’s final nuclear plant at Maanshan completes this phase-out strategy, but it comes at a precarious time. Power demand is projected to surge 13% by 2030, driven primarily by energy-intensive industries like semiconductor manufacturing and data centers. The timing creates a perfect storm of energy challenges that the island nation must navigate while balancing environmental concerns, economic necessities, and national security considerations in an increasingly tense geopolitical landscape.

Economic and Security Implications
The economic consequences of Taiwan’s nuclear phaseout are substantial and immediate. Each decommissioned reactor drives up annual liquefied natural gas (LNG) import costs by approximately $500 million. By 2030, Taiwan may need to spend an additional $2 billion yearly on LNG imports. This financial burden has already strained Taipower, Taiwan’s primary electricity provider, which faces mounting losses due to rising fuel costs and investments in renewable energy infrastructure that have yet to reach targeted capacity.
“Taipower can only stop having losses if it extends the life of nuclear plants”, said Java Yang
The increased reliance on imported fuels creates a strategic vulnerability that cannot be overlooked, especially given China’s claims on Taiwan and regional tensions. With nuclear power’s contribution dropping to approximately 5% of Taiwan’s energy mix in 2024, and fossil fuels accounting for 84%, the island becomes more dependent on energy imports that could potentially be disrupted during conflicts. This dependency represents not just an economic challenge but a national security concern that has prompted reconsideration of the nuclear phaseout strategy at the highest levels of government.
Shifting Public Opinion and Policy Reconsideration
Public sentiment in Taiwan appears to be evolving on nuclear energy. The protest that once drove environmental policy is now being countered by demonstrations supporting the continued operation of the Maanshan nuclear plant. Taiwan’s legislature has revised nuclear power regulations, potentially opening the door for atomic plants to restart. Opposition parties are planning public referendums on resuming nuclear operations, indicating a significant shift in the national conversation around energy security versus nuclear risks.
“I told them, if they insisted on coming in, we would burn the ship that night”, said Kuo Chien-ping.
The government initially aimed to replace nuclear energy with wind and solar power, but these renewable sources have not developed quickly enough to meet demand. The resulting gap must be filled with fossil fuels, primarily imported LNG, which undermines Taiwan’s emissions reduction targets. This reality has forced a pragmatic reassessment of energy priorities as Taiwan balances environmental ideals with the practical demands of powering its economy and maintaining energy security in an uncertain geopolitical environment.
The Future of Taiwan’s Energy Mix
Taiwan stands at a critical energy crossroads. The shutdown of its final nuclear reactor completes a journey that began with environmental protests decades ago but opens new questions about how to power its future. The semiconductor industry that forms the backbone of Taiwan’s economy requires reliable, abundant electricity—a requirement that will only grow as global tech demands increase. The tension between environmental concerns, economic necessities, and security considerations will likely shape energy policy debates for years to come.
For the indigenous residents of Orchid Island who once blocked nuclear waste shipments, health concerns remain about waste stored on their land. For Taiwan’s policymakers, the challenge is more complex than ever: secure reliable energy sources, maintain economic competitiveness, reduce environmental impact, and ensure national security. The decisions made in the coming months and years will determine whether Taiwan’s nuclear phaseout represents environmental progress or strategic vulnerability in an increasingly competitive and uncertain world.
