Taichung Combined Cycle Power Plant Project
04/23/24
Project Description
Background
Respond to the growth of domestic power consumption, Taiwan Power Company (TPC) follows the government’s energy policy and promotes the " Taichung Combined Cycle Power Plant Project" to ensure stable power supply. TPC plans to install two gas-fired Combined Cycle units in adjacent to the existing Taichung coal-fired Power Plant station , with a total capacity of about 2.6million kilowatts. This project also includes one berth liquefied natural gas(LNG) unloading pier, a LNG gasification terminal with five LNG storage tanks and associated auxiliary facilities and pipelines, which will be TPC’s first built and self-operated LNG terminal.
Project Location and Scope
The Taichung Combined Cycle Power Plant Project, covering an area of 13.4 hectares, is seated in the Southern of No.9 and No.10 coal-fired units of Taichung Power Plant.

Note：
1. The Project schedule amendment was officially approved by the Executive Yuan on October 5, 2022.
2. Up to 2024/3, Overall progress is delayed about 0.11%. The reasons are due to encountering huge underground obstacles makes it difficult to perform steel sheet pile and point well operations and the poor-quality concrete for the foundation piles is about 4m thick, which causes time-consuming processing and affects the excavation progress.
