Events.
2005.
On 16 December 2005, the power plant combined cycle Unit 1 and 2 with a capacity of 435.9 MW each went into commercial operation.

On 31 December 2009, the power plant combined cycle Unit 4 and 5 were converted from low pressure to high pressure and started commercial operation on the day. This conversion increased the plant capacity by 507.4 MW.
2012.
In 2012, the power plant carried out the "Guidance Plan for Energy Industry Adaptive Action in Response to Climate Change" to conduct an analysis on the impact of climate change, a vulnerability check and risk evaluation for the facilities within their domain.
2017.
On 15 August 2017 at 4:52 p.m., the six generators of the power plant fully tripped due to operation technical error, disrupting the supply of 4 GW of electricity. During the power supply equipment replacement for a control system of the plant's metering station, the worker did not switch the system from auto mode to manual mode before starting the work, resulting the two gas supply pipe valves closed and stop the supply of liquefied natural gas fuel source for two minutes. Electricity rationing was implemented at 6:00 p.m. and ended at 9:40 p.m. The outage hit northern half of Taiwan Island, affecting 6.68 million households. Taipower responded by offering one day electricity charge cut from each household bill, which resulted in NT$270 million of revenue loss to the company.
Economic Affairs Minister Lee Chih-kung resigned shortly afterwards to take responsibility. Premier Lin Chuan appointed Deputy Minister Shen Jong-chin as acting Minister to replace Lee.
