History
In the early 1960s, Taipower Company (TPC) decided to set up a power plant in Tongxiao. Initially, Tongxiao Power Plant was fueled with diesel. In 1978, TPC rebuilt the power units with three combined cycle units (the fuel remained diesel, these units also called old #1~#3), they were the first combined cycle units in Taiwan. In 1990, TPC established units #4 and #5, while unit #6 (fueled by natural gas) was built in 1997.[citation needed] Later, TPC decided to renew old #1~#3 units (3 old units generate 763 MW electricity). The New Combined Cycle units started commercial operation on 27 February 2018 (New #1 Unit), 30 May 2019 (New #2 Unit), and 26 May 2020 (New #3 Unit).[8][9] The new power units are established on the area of removed oil tanks.[citation needed]
On 30 May 2018, a power outage occurred at the power plant at 3:12 p.m. due to the tripping of high voltage transmission line. A total of 70,391 households were left without power. The power was then restored at 4:38 p.m.[10]
Technical description
The new power units have the electricity capacity 892.6 MW each (3 new units are 2677.8 MW), and its heat efficiency is 60.7%.[citation needed]
Transportation
Tunghsiao Power Plant is accessible within walking distance West from Tongxiao Station of Taiwan Railway.
