About 5.49 million households yesterday lost power in one of the nation’s largest power disruptions since 2017 due to a switch malfunction at Kaohsiung’s Hsinta Power Plant (興達電廠), the Ministry of Economic Affairs said.
The incident sent the power plant offline, leading to a circuit malfunction at the Longqi Extra High Voltage Substation (龍崎超高壓變電所), which caused several power plants in the south to shut down.
About 10.5 million kilowatts was lost during the incident, Taiwan Power Co (Taipower, 台電) said.

The Hsinta plant accounts for about 6 percent of the nation’s electricity production.
Taipower activated hydroelectric, liquefied natural gas and coal-fired power plants to fill the supply gap, it said.
Minister of Economic Affairs Wang Mei-hua (王美花) last night requested reprimands for the massive blackouts, as Taipower chairman Yang Wei-fuu (楊偉甫) and president Chung Bin-li (鍾炳利) offered their resignations, which are subject to the Cabinet’s approval.

Major science parks reported only minor effects from the blackouts. Taiwan Semiconductor Manufacturing Co (台積電), the world’s biggest contract chipmaker, said the incident had no significant impact on its production lines.
United Microelectronics Corp (聯電), the world’s No. 3 contract chipmaker, said the incident had brought production to a halt at its plant in the Tainan section of the Southern Taiwan Science Park (南部科學園區), but it was manageable.
LCD panel maker AU Optronics Corp (友達光電) said that some of its manufacturing facilities experienced a sudden voltage drop, but operations remained normal, while Innolux Corp (群創) said power went off at one of its plants, but that operations were recovering and it is evaluating the impact.
Power at the Kaohsiung section of the Southern Taiwan Science Park was fully restored by noon, the park’s administration said.
The ministry said that 48 industrial parks were affected by the blackout, and power had been restored to 36 of them as of yesterday afternoon.
Liu Chi-chuan (劉繼傳), operations management deputy director at the ministry’s Export Processing Zone Administration, said that 521 companies in industrial parks in the south were affected by the blackout, and power had been restored to 358 of them as of 1pm yesterday.
Executive Yuan spokesman Lo Ping-cheng (羅秉成) said that the government had asked the ministry and Taipower to thoroughly investigate the cause of the outage.
The government would reprimand those responsible if the large-scale blackout was proven to have been caused by human error, Lo quoted Premier Su Tseng-chang (蘇貞昌) as saying.
Wang said that human error was to blame for the blackout and that the ministry would complete its investigation in three days.

A signaling system malfunction disrupted high-speed rail (HSR) services beginning at 8am today, with trains temporarily reduced to three northbound and three southbound trains per hour as authorities conduct inspections. The malfunction occurred on a section of track in Miaoli County during pre-operation checks early this morning, forcing northbound and southbound trains to use a single track, the HSR operator said. The regular schedule has been replaced with three hourly trains offering only nonreserved seating in each direction, stopping at every station, it said, adding that business class cars would still have reserved seating. Departures from terminal stations are scheduled at the top
Taiwan is still in the process of assessing the possibility of recruiting workers from Eswatini, the Ministry of Foreign Affairs said yesterday, adding that its goal is to help Eswatini upgrade its vocational training centers.

A US uncrewed surface vessel (USV) encountered multiple Chinese warships during an autonomous transit of the Taiwan Strait, US defense company Seasats said in a statement on Wednesday. Seasats announced that a Lightfish USV had completed the first autonomous transit of the Taiwan Strait.

The Lightfish encountered multiple Chinese warships, one of which was a Chinese People’s Liberation Army Navy (PLAN) Type 056 corvette, it said. The Chinese vessels were operating “well within Taiwan’s exclusive economic zone without transmitting their identity via the
VERBOSE VESSELS: A CGA cutter and a China Coast Guard exchanged verbal barbs for more than a day in Taiwanese-controlled waters before the Chinese vessel left The Taiwanese and Chinese coast guards had a standoff near the strategically located Pratas Islands (Dongsha Islands, 東沙群島) in the north of the South China Sea, the Coast Guard Administration (CGA) said yesterday. The two sides engaged in intense radio exchanges over sovereignty claims during the 33-hour standoff. China Coast Guard vessel 3501 eventually left the restricted waters, 26.6 nautical miles (49.2km) west of the Pratas Islands, at 5pm yesterday, the CGA said. Lying approximately between southern Taiwan and Hong Kong, the Taiwan-controlled Pratas are seen by some security experts as vulnerable to Chinese attack due to their distance — more than
