Minister of Economic Affairs Lee Chih-kung (李世光) yesterday said the suspension of Formosa Chemicals & Fibre Corp’s (台灣化學纖維) three power generators at its Changhua County plant would impact the stability of the nation’s electricity supply.
Formosa Chemicals’ coal-fired cogeneration power units had been one of Taiwan Power Co’s (Taipower, 台電) most important supplies of electricity over the past decades, as they could generate electricity with high efficiency, Lee said.
“The suspension of Formosa Chemicals’ electricity supply affects the total operating reserve by about 0.6 to 0.7 percent,” and it would have a long-term impact on electricity supply, Lee told reporters on the sidelines of a meeting of the legislature’s Economics Committee in Taipei.
The closure of the Changhua plant, which manufactured rayon and nylon, would also affect downstream companies in the local textile industry, Lee said.
Lee said it is possible to lower the carbon emissions or reduce air pollution from the cogeneration power units by adopting new technologies, but the Changhua County Government appears to have a different stance to the central government regarding the standards for carbon emissions, he added.
Lee said he is worried that the county government’s strict measures on Formosa Chemicals’ Changhua plant would be replicated by other local governments.
The permit for Formosa Petrochemical Corp’s (台塑石化) coal-fired power units at its naphtha cracker in Yunlin County’s Mailiao Township (麥寮) is set to expire in April next year and the nation could suffer power shortages if the local government decides to shut down the Mailiao plant, which generates about 1.8 million kilowatts, as much as two nuclear power reactors, Lee said.
The ministry is drafting an impact analysis on the Changhua plant’s closure for the Executive Yuan and the Presidential Office, Lee said.
The ministry would continue discussions with the Environmental Protection Administration and Formosa Chemicals to seek a solution, he said.
Meanwhile, the Economics Committee passed a nonbinding resolution that privately owned coal-fired power plants should be transformed to gas power plants before their electricity supply contracts with Taipower can be renewed.
The resolution is an effort to reduce carbon emissions from coal-fired power plants.
The committee said the coal-fired power plants should suspend operations if they cannot be transformed into gas power plants and that Taipower should not renew the contracts if privately owned utilities fail to do so.
That includes Formosa Petrochemical’s Mailiao plant and Taiwan Cement Corp’s (台泥) coal-fired Hoping plant (和平電廠), whose contracts with Taipower expire in 2024 and 2025 respectively.
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
With this year’s Semicon Taiwan trade show set to kick off on Wednesday, market attention has turned to the mass production of advanced packaging technologies and capacity expansion in Taiwan and the US. With traditional scaling reaching physical limits, heterogeneous integration and packaging technologies have emerged as key solutions. Surging demand for artificial intelligence (AI), high-performance computing (HPC) and high-bandwidth memory (HBM) chips has put technologies such as chip-on-wafer-on-substrate (CoWoS), integrated fan-out (InFO), system on integrated chips (SoIC), 3D IC and fan-out panel-level packaging (FOPLP) at the center of semiconductor innovation, making them a major focus at this year’s trade show, according
DEBUT: The trade show is to feature 17 national pavilions, a new high for the event, including from Canada, Costa Rica, Lithuania, Sweden and Vietnam for the first time The Semicon Taiwan trade show, which opens on Wednesday, is expected to see a new high in the number of exhibitors and visitors from around the world, said its organizer, SEMI, which has described the annual event as the “Olympics of the semiconductor industry.” SEMI, which represents companies in the electronics manufacturing and design supply chain, and touts the annual exhibition as the most influential semiconductor trade show in the world, said more than 1,200 enterprises from 56 countries are to showcase their innovations across more than 4,100 booths, and that the event could attract 100,000 visitors. This year’s event features 17
Hon Hai Precision Industry Co (鴻海精密), which assembles servers for Nvidia Corp, yesterday said that revenue last month rose 10.61 percent year-on-year, driven by strong growth in cloud and networking products amid continued front-loading orders for artificial intelligence (AI) server racks. Consolidated revenue expanded to NT$606.51 billion (US$19.81 billion) last month from NT$548.31 billion a year earlier, marking the highest ever in August, the company said in a statement. On a monthly basis, revenue was down 1.2 percent from NT$613.86 billion. Hon Hai, which is also a major iPhone assembler, added that its electronic components division saw significant revenue growth last month, boosted
