The overwhelming support from participating voters in Saturday’s referendum on restarting the Ma-anshan Nuclear Power Plant in Pingtung County showed that nuclear energy remains a divisive issue and highlighted the need for a more diverse energy mix in Taiwan, academics said yesterday.
On the question “Do you agree that the Ma-anshan Nuclear Power Plant should continue operations upon approval by the competent authority and confirmation that there are no safety concerns?” 4,341,432 people, or about 73.5 percent of participating voters, cast “yes” ballots, the Central Election Commission said.
However the referendum still failed to pass, as it did not meet the required threshold of 5,000,523 affirmative votes, or 25 percent of eligible voters. Voter turnout was 29.53 percent.

The result means that Taiwan would remain without nuclear power, although the government has not ruled out reintroducing it.
“The failure to reach the threshold shows that controversy remains,” said Chen Jong-shun (陳中舜), an associate researcher at the Center for Green Economy of the Chung-Hua Institution for Economic Research.
Chen said that based on its project experience, Taiwan Power Co (Taipower) could, with broad social consensus, restart operations at the plant in “as little as two years.”
However, as there is no consensus “the future is still unclear,” he said.
Chen Shih-hau (陳詩豪), director-general of Research Division V of the Taiwan Institute of Economic Research, said that public opinion must be weighed when formulating energy security policy, otherwise it “only increases variables” in Taipower’s planning.
For example, the long-delayed Fourth Nuclear Power Plant in New Taipei City’s Gongliao District (貢寮), which never entered commercial operation, created supply pressures in northern Taiwan until a gas-fired generator at the Datan Power Plant in Taoyuan came online, he said.
The delays forced the continued operation of heavy oil-fired units at the Hsieh-ho Power Plant in Keelung, delaying the plant’s planned conversion from oil to natural gas, he said.
Chen Shih-hau said that restarting existing plants is less costly than building new ones, but shutting down large nuclear facilities has “a significant impact,” which is “why energy planning emphasizes diversification.”
National Chung Hsing University environmental engineering professor Tsuang Ben-jei (莊秉潔) said that the most feasible form of distributed energy is solar power with battery storage, followed by natural gas storage with gas-fired units and geothermal power.
Such power would cost about NT$5 to NT$10 per kilowatt-hour, Tsuang said.
State-run oil refiner CPC Corp, Taiwan operates a natural gas storage facility 3km underground in Miaoli County, which could supply Taiwan with 26 days of reserve energy, he said.
Restoring other natural underground storage sites could increase reserves to more than 600 days, he added.
Meanwhile, in the run-up to Saturday’s vote, many business leaders had voiced support for the referendum, including Lin Por-fong (林伯豐), chairman of the Third Wednesday Club, a prominent business association, citing concerns over stability.
Lin urged the government to rethink energy policy in a way that supports economic growth, ensuring a stable power supply and reasonable electricity prices.
“This cannot be achieved without nuclear power,” he said.
Pegatron Corp chairman Tung Tzu-hsien (童子賢) also believes that nuclear energy is vital for reducing carbon emissions, Lin said.
Tung — a vocal advocate for the referendum — on Saturday said that every unit of carbon-free electricity is precious, particularly with global carbon taxes on the horizon.
“Taiwan’s biggest problem is not a power shortage; that is only a potential pressure. Even more serious is the lack of carbon-free electricity,” he said.
Fossil fuel plants account for 79.7 percent of Taiwan’s electricity generation, including coal (31.1 percent), oil (1.4 percent) and natural gas (47.2 percent), Taipower data showed.
Renewables make up 11.9 percent, it showed.
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
The first of 10 new high-capacity trains purchased from South Korea’s Hyundai Rotem arrived at the Port of Taipei yesterday to meet the demands of an expanding metro network, Taipei Rapid Transit Corp (TRTC) said yesterday. The train completed a three-day, 1,200km voyage from the Port of Masan in South Korea, the company said. Costing NT$590 million (US$18.79 million) each, the new six-carriage trains feature a redesigned interior based on "human-centric" transportation concepts, TRTC said. The design utilizes continuous longitudinal seating to widen the aisles and optimize passenger flow, while also upgrading passenger information displays and driving control systems for a more comfortable
Taiwan's first indigenous defense submarine, the SS-711 Hai Kun (海鯤, or Narwhal), departed for its 13th sea trial at 7am today, marking its seventh submerged test, with delivery to the navy scheduled for July. The outing also marked its first sea deployment since President William Lai (賴清德) boarded the submarine for an inspection on March 19, drawing a crowd of military enthusiasts who gathered to show support. The submarine this morning departed port accompanied by CSBC Corp’s Endeavor Manta (奮進魔鬼魚號) uncrewed surface vessel and a navy M109 assault boat. Amid public interest in key milestones such as torpedo-launching operations and overnight submerged trials,
