This geographic advantage, combined with its substantial 2650 MW capacity, ensures that Talin remains a cornerstone of southern Taiwan's power supply. The plant's modernization efforts reflect a broader national priority: to extend the economic life of existing coal assets through technological retrofitting rather than immediate decommissioning. This strategy helps stabilize electricity prices and provides grid inertia, which is vital for system stability. The continued operation of Talin demonstrates how legacy infrastructure can be revitalized to meet contemporary performance standards, serving as a model for other aging power plants across the region.
What are the technical specifications of the Talin Power Plant?
The plant is operated by the Taiwan Power Company and has a total installed capacity of 2650 MW. It is classified as operational and was originally commissioned in 1969. The facility utilizes a combination of coal and natural gas to generate electricity, featuring four distinct operational units that contribute to its mixed-fuel profile.
Coal-Fired Units
The plant includes two ultra-supercritical coal-fired units, each with a capacity of 800 MW. These units represent a significant portion of the plant's total output, contributing 1600 MW to the overall 2650 MW capacity. The ultra-supercritical technology allows for higher thermal efficiency compared to subcritical or supercritical counterparts, making these units key components of the plant's coal-generation capabilities. These units are part of the mixed-generation strategy, allowing the Taiwan Power Company to leverage coal as a primary fuel source while maintaining flexibility through gas-fired backups.
Gas-Fired Units
In addition to the coal-fired units, the Talin Power Plant features two gas-fired units that provide operational flexibility and help reduce emissions during peak demand or when coal supply is variable. One gas-fired unit has a capacity of 500 MW, while the other has a capacity of 550 MW. Together, these gas units contribute 1050 MW to the plant's total capacity. The inclusion of gas-fired units allows the plant to adjust its output more rapidly than coal-fired units, making them valuable for load-following and peaking operations. The gas units also contribute to the plant's status as a mixed-generation facility, diversifying the fuel sources used for electricity production.
Commercial Operation Dates
The Talin Power Plant was originally commissioned in 1969, marking the beginning of its operational history. While the specific commercial operation dates for each of the four units are not detailed in the available grounding, the plant has undergone expansions and upgrades over the decades to incorporate the two 800 MW ultra-supercritical coal-fired units and the two gas-fired units. The 1969 commissioning date refers to the initial phase of the plant, which has since evolved into the current mixed-generation configuration.
