The operations of a liquefied natural gas (LNG) receiving terminal in Taichung have returned to normal after technical glitches on Friday night, state-owned refiner CPC Corp, Taiwan said yesterday.
The company said it would inspect the facility to determine the cause of the incident.
Technical problems with the terminal’s safety instrumented system at about 8:10pm suspended natural gas output from the facility, leading to a decline in power supply from the Tatan Power Plant in Taoyuan’s Guanyin District (觀音), which generates electricity using natural gas from the Taichung LNG receiving terminal, CPC said.

A safety instrumented system is a set of hardware and software controls that can shut down a chemical, nuclear, electrical or mechanical system, or part of it, if a hazardous condition is detected.
In response to the technical problems at the terminal and reduced power supplies from the two power plants, CPC immediately set up an emergency task force to investigate the incident.
Engineers enabled the facility to gradually resume operations at about 8:58pm, with output returning to normal at about 11:29pm, it said.
CPC said it worked with Taiwan Power Co (Taipower), the sole state-run power supplier, to stabilize electricity supply across the country during the incident.
After the glitches at the Taichung terminal, power from the Tatan Power Plant dropped about 2.5 gigawatts (GW), while the electricity supply from privately owned Haihu Power Plant in Taoyuan’s Lujhu District (蘆竹) fell about 0.9GW, Taipower said.
In response, Taipower boosted electricity production from hydraulic generators and pumped-storage hydropower equipment by 1.1GW, it said.
As the reduced supply from Tatan and Haihu largely affected users in northern Taiwan, the company increased electricity production at the Hsieh-he Power Plant in Keelung by 0.55GW and activated turbo generators at the Guosheng Nuclear Power Plant in New Taipei City’s Wanli District (萬里), it said.
It also increased electricity generation by 0.3GW at the Talin Power Plant in Kaohsiung, and activated turbo generators at the Ma-anshan Nuclear Power Plant in Pingtung County’s Hengchun Township (恆春), it added.
Before the incident in Taichung, the nation’s operating reserve margin — the amount of additional power that can be called upon quickly to meet electricity demand in Taiwan — was at about 13 percent, Taipower said.
As the glitches occurred during off-peak hours, the operating reserve margin was at more than 15 percent, which meant that the power supply remained stable, it said.
With the Taichung LNG receiving terminal back to normal, people do not need to worry about supply issues, it added.
Ahead of the technical problems, the LNG receiving terminal sent about 900 tonnes of natural gas per hour to northern Taiwan for power production, and after the safety instrumented system was repaired, the volume rose to about 1,000 tonnes, the CPC said.
It said that the construction of a third LNG receiving terminal planned in Tatan should be completed as soon as possible to boost natural gas volume and stabilize the power supply in Taiwan.
A relatively large earthquake may strike within the next two weeks, following a magnitude 5.2 temblor that shook Taitung County this morning, the Central Weather Administration (CWA) said. An earthquake struck at 8:18am today 10.2km west of Taitung County Hall in Taitung City at a relatively shallow depth of 6.5km, CWA data showed. The largest intensity of 4 was felt in Taitung and Pingtung counties, which received an alert notice, while areas north of Taichung did not feel any shaking, the CWA said. The earthquake was the result of the collision between the Philippine Plate and the Eurasian Plate, the agency said, adding
Snow fell in the mountainous areas of northern, central and eastern Taiwan in the early hours of yesterday, as cold air currents moved south. In the northern municipality of Taoyuan, snow started falling at about 6am in Fusing District (復興), district head Su Tso-hsi (蘇佐璽) said. By 10am, Lalashan National Forest Recreation Area, as well as Hualing (華陵), Sanguang (三光) and Gaoyi (高義) boroughs had seen snowfall, Su said. In central Taiwan, Shei-Pa National Park in Miaoli County and Hehuanshan National Forest Recreation Area in Nantou County saw snowfall of 5cm and 6cm respectively, by 10am, staff at the parks said. It began snowing
HOLIDAY EXERCISE: National forest recreation areas from north to south offer travelers a wide choice of sights to connect with nature and enjoy its benefits Hiking is a good way to improve one’s health, the Forestry and Nature Conservation Agency said, as it released a list of national forest recreation areas that travelers can visit during the Lunar New Year holiday. Taking a green shower of phytoncides in the woods could boost one’s immunity system and metabolism, agency Director-General Lin Hwa-ching (林華慶) cited a Japanese study as saying. For people visiting northern Taiwan, Lin recommended the Dongyanshan National Forest Recreation Area in Taoyuan’s Fusing District (復興). Once an important plantation in the north, Dongyanshan (東眼山) has a number of historic monuments, he said. The area is broadly covered by
Global bodies should stop excluding Taiwan for political reasons, President William Lai (賴清德) told Pope Francis in a letter, adding that he agrees war has no winners. The Vatican is one of only 12 countries to retain formal diplomatic ties with Taiwan, and Taipei has watched with concern efforts by Beijing and the Holy See to improve ties. In October, the Vatican and China extended an accord on the appointment of Catholic bishops in China for four years, pointing to a new level of trust between the two parties.
