Of the 82 wind turbines that make up Taiwan Power Co's (Taipower, (台電) wind-powered energy generation plans, as many as 51 turbines have at one time or another been inoperative.
Taipower blames the high rate of malfunctioning on Taiwan’s hot climate and lack of supporting equipment. The high rate of breakdown is a significant setback to the implementation of the government’s renewable energy policy.
To meet government targets for clean energy, Taipower planned to invest NT$19 billion (US$624 million) in 180 wind turbines, with a total capacity of 330,000 kilowatts, between 2003 and 2010. However, to date, only 82 have been completed, with the malfunction rate reaching a high 62 percent.
Taipower said that, of the malfunctioning turbines, three were manufactured by GE, 22 by Harakosan and six by Gamesa. Most of the turbines are distributed along the western shoreline.
In terms of generation, the 82 completed turbines have generated 560 million kilowatt-hours of electricity. At NT$2 per kilowatt-hour, the turbines have generated NT$1.12 billion, a miniscule sum compared with its investment of nearly NT$10 billion.
As for capacity utilization, only the turbines in Penghu County and Changhua County were able to operate at 47 percent and 35 percent respectively. In other areas, such as in Shihmen (石門), Taipei County, and Hengchun (恆春), Pingtung County, the turbines were operating at less than 30 percent capacity.
Commenting on the major problems surrounding wind power generation, an unnamed director from Taipower described the situation as “utterly ridiculous.” Some Taipower staff also questioned the fact that the department in charge of wind-power generation had not been held responsible nor faced disciplinary action.
Sources say that the 51 faulty turbines were all contract based on the most advantageous, rather than the lowest, bids.
A recently discovered supernova is the brightest and closest to Earth identified in the past decade, and can be observed with basic equipment, the Taipei Astronomical Museum said on Wednesday. The supernova has an absolute magnitude of 14.9 in luminosity and is in the Pinwheel Galaxy (M101) about 21 million light-years from Earth. It was discovered early on May 20 by Japanese amateur astronomer Koichi Itagaki, who immediately reported the finding to the International Astronomical Union, the museum said. The supernova was designated SN 2023ixf following the astronomical naming conventions for supernovas, it added. The museum said that it observed
Tropical storm Guchol is moving in a northeasterly direction off the east coast of the Philippines and will not hit Taiwan, but will impact local weather starting on Friday, the Central Weather Bureau said Thursday. The storm would bring a low-pressure system northward toward the vicinity of Taiwan, forecaster Chao Hung (趙竑) said. Northern Taiwan will see intermittent rain showers in the morning, and thunderstorms in the afternoon on Friday, he said, adding that rain would be heavier on the east coast and in the central-southern mountainous areas. Rainfall would continue into Saturday, and would spread throughout Taiwan proper, he
Exiled Chinese democracy advocate Wang Dan (王丹) yesterday denied an accusation by former Taiwanese political worker Lee Yuan-chun (李援軍) that Wang had sexually harassed him in a hotel room in New York nine years ago. There was a huge gap between Lee’s accusation and his own understanding and memory, Wang wrote on Facebook, adding it was hard for him to respond further regarding a “unilateral description” made by someone else. Wang made the remarks after his initial response on Facebook was met with criticism, with people saying he did not directly address the allegation. Lee on Friday wrote on Facebook that he
A man was arrested in Hsinchu on Saturday on suspicion of filming women in the women’s washroom of a shopping mall in the city, local Chinese-language media reported on Thursday. The man was arrested at around noon on Saturday when a woman using a stall in the mall’s washroom noticed a cellphone being held above her from the neighboring stall, reports said. The woman ran out of the washroom and yelled to her husband to help her, after which the suspect – who was dressed as a woman – attempted to flee, but was subdued by other men until police
