Hsinta Power Plant Combined Cycle Renewal Project
In response to the existing units retirement schedule, long-term power load growth demands and enhancing power plants performance, promote competitiveness and reducing CO2 as well as air pollutants emission, Taiwan Power Company therefore initiate "Hsinta Power Plant Combined Cycle Renewal Project" (hereinafter referred as “The Project”), the total Project capacity is about 3,900 Mega watts of Combined Cycle Units.
Project Location and Scope
The planned power generation facility is located in Yong-An Salt Pan on the southeast side of Hsinta Power Plant and is located in Yong-An District of Kaohsiung City, covering an area of about 78.6 hectares and other 3.59 hectares in the existing plant, with a total of 82.19 hectares as the planned area.
