The operators of Taiwan’s first privately run megawatt-level geothermal power plant in Yilan County have revealed that the site has produced more than 38 million kilowatt-hours (kWh) of electricity since opening in October 2021.
Staff at the 4.2MW Cingshuei Geothermal Power Plant shared the information during a visit by Minister Without Portfolio Wu Tze-cheng (吳澤成) and Yilan County Commissioner Lin Zi-miao (林姿妙) on Friday.
The development of the geothermal power plant in Datong Township (大同) was contracted to Yi Yuan Co (宜元股份), a joint venture of Fabulous Power Co (結元能源開發) and Taiwan Cogeneration Corp (台灣汽電共生), on a build-and-operate, and rehabilitate-operate-transfer model, when Wu was acting Yilan County commissioner in 2017.

The power plant then began operations October 2021 during Lin’s term and has produced 38 million kWh of power as of the end of July, its operators said.
The construction began in 2017 with an initial investment of NT$765 million (US$23,90 million), and the power plant was completed in September 2021 before securing a license from the Bureau of Energy a month later.
The plant has adopted “binary-cycle generators” that cause less damage to turbines and less precipitation of solids. the Yilan County government said.
The 38.25 million kWh generated can meet the demand of about three-quarters of the combined households in Datong Township and the neighboring Sanshing Township (三星), the county government said.
The two townships consist of about 10,000 small households.
When Wu, who concurrently serves as head of the Executive Yuan’s Public Construction Commission, inquired whether the accumulation of solid substances — commonly known as “fouling” — could possibly again affect the plant’s operations, he was assured by Yi Yuan Co that the new generator units have been efficient and so far the fouling rate has been better than before.
Touting the power plant as a crucial energy provider for Yilan County and a milestone for Taiwan’s effort to achieve sustainable development, Lin said she is expecting to continue local-central collaboration on power generation in the future.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) secured a record 70.2 percent share of the global foundry business in the second quarter, up from 67.6 percent the previous quarter, and continued widening its lead over second-placed Samsung Electronics Co, TrendForce Corp (集邦科技) said on Monday. TSMC posted US$30.24 billion in sales in the April-to-June period, up 18.5 percent from the previous quarter, driven by major smartphone customers entering their ramp-up cycle and robust demand for artificial intelligence chips, laptops and PCs, which boosted wafer shipments and average selling prices, TrendForce said in a report. Samsung’s sales also grew in the second quarter, up
LIMITED IMPACT: Investor confidence was likely sustained by its relatively small exposure to the Chinese market, as only less advanced chips are made in Nanjing Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) saw its stock price close steady yesterday in a sign that the loss of the validated end user (VEU) status for its Nanjing, China, fab should have a mild impact on the world’s biggest contract chipmaker financially and technologically. Media reports about the waiver loss sent TSMC down 1.29 percent during the early trading session yesterday, but the stock soon regained strength and ended at NT$1,160, unchanged from Tuesday. Investors’ confidence in TSMC was likely built on its relatively small exposure to the Chinese market, as Chinese customers contributed about 9 percent to TSMC’s revenue last
LOOPHOLES: The move is to end a break that was aiding foreign producers without any similar benefit for US manufacturers, the US Department of Commerce said US President Donald Trump’s administration would make it harder for Samsung Electronics Co and SK Hynix Inc to ship critical equipment to their chipmaking operations in China, dealing a potential blow to the companies’ production in the world’s largest semiconductor market. The US Department of Commerce in a notice published on Friday said that it was revoking waivers for Samsung and SK Hynix to use US technologies in their Chinese operations. The companies had been operating in China under regulations that allow them to import chipmaking equipment without applying for a new license each time. The move would revise what is known
UNCERTAINTY: A final ruling against the president’s tariffs would upend his trade deals and force the government to content with billions of dollars in refunds The legal fight over US President Donald Trump’s global tariffs is deepening after a federal appeals court ruled the levies were issued illegally under an emergency law, extending the chaos in global trade. A 7-4 decision by a panel of judges on Friday was a major setback for Trump, even as it gives both sides something to boast about. The majority upheld a May ruling by the Court of International Trade that the tariffs were illegal. However, the judges left the levies intact while the case proceeds, as Trump had requested, and suggested that any injunction could potentially be narrowed to apply
