The Cingshuei Geothermal Power Plant, the first privately built geothermal plant in Taiwan, is set to obtain a commercial license by the end of this month.
The 4.2 megawatt (MW) plant in Yilan County would generate enough electricity to power 10,000 households and has potential for expansion to further utilize the area’s geothermal resources.
Yilan has long been recognized as having the greatest potential for geothermal energy generation in Taiwan, with hot springs in the area bubbling so hot that tourists boil eggs in them.

State-run Taiwan Power Co (台電) has since the 1980s sponsored a 3MW plant in Cingshuei, but the project ran into trouble due to corrosion and silt blockage, and was eventually abandoned.
The current project, developed by Fabulous Power Co (結元能源開發), imported equipment from Nevada-based Ormat Technologies Inc.
The plant extracts water with temperatures of up to 180°C from 1,200m to 2,100m underground and runs it through a heat exchanger to generate electricity, before pumping it back into the ground again.
“The plant takes the heat, but not the water,” the Yilan County Government said in a press release.
Fabulous Power won the right to use the land occupied by the failed pilot plant in 2017, the county government said.
Fabulous Power president Lin Bo-hsiu (林伯修) last month told the Chinese-language Business Today magazine that he never gave up hope.
“People told me the energy just wasn’t there, but for eight years I went from well to well, and I studied different methods and different equipment,” Lin said.
Lin said that the 4.2MW generation capacity is just the beginning.
He estimated there was 30MW to 60MW of power generation potential in the Chingshuei area alone.
Reliable geothermal energy could be a perfect complement to other alternative energy sources such as solar and wind, which generate power only intermittently, he said.
STRONG INTEREST: Analysts have pointed to optimism in TSMC’s growth prospects in the artificial intelligence era as the cause of the rising number of shareholders The number of people holding shares of chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) hit a new high last week despite a decline in its stock price, the Taiwan Depository and Clearing Corp (TDCC, 台灣集保) said. The number of TSMC shareholders rose to 2.46 million as of Friday, up 75,536 from a week earlier, TDCC data showed. The stock price fell 1.34 percent during the same week to close at NT$1,840 (US$57.55). The decline in TSMC’s share price resulted from volatility in global tech stocks, driven by rising international crude oil prices as the war against Iran continues. Dealers said
PRICE HIKES: The war in the Middle East would not significantly disrupt supply in the short term, but semiconductor companies are facing price surges for materials Taiwan’s semiconductor companies are not facing imminent supply disruptions of essential chemicals or raw materials due to the war in the Middle East, but surges in material costs loom large, industry association SEMI Taiwan said yesterday. The association’s comments came amid growing concerns that supplies of helium and other key raw materials used in semiconductor production could become a choke point after Qatar shut down its liquefied natural gas (LNG) production and helium output earlier this month due to the conflict. Qatar is the second-largest LNG supplier in the world and accounts for about 33 percent of global helium output. Helium is
China is clamping down on fertilizer exports to protect its domestic market, industry sources said, putting an additional strain on global markets that were already grappling with shortages caused by the US-Israeli war on Iran. China is among the largest fertilizer exporters — shipping more than US$13 billion of it last year — and it has a history of controlling exports to keep prices low for farmers. Shipments through the war-blocked Strait of Hormuz account for about one-third of the sea-borne supply. This month, Beijing banned exports of nitrogen-potassium fertilizer blends and certain phosphate varieties, sources said. The ban, which has not
AMAZING ABUNDANCE: Elon Musk has announced plans for a new facility in Texas which would manufacture chips for Tesla and SpaceX to use in robotics and AI Elon Musk said his Terafab project — a grand plan to eventually manufacture his own chips for robotics, artificial intelligence (AI) and space data centers — would be built in Austin and jointly run by Tesla Inc and Space Exploration Technologies Corp (SpaceX). Musk, the chief executive officer of the two companies, said he would start off with an “advanced technology fab” in Austin that would have all of the equipment necessary to make chips of any kind. The project would call for one day supporting 1 terawatt (TW) of computing power per year, the amount Musk expects the companies to
