Project Description

The Ta-Tan Power Plant, operated by Taiwan Power Company, is the largest natural gas power plant in Taiwan. The plant area is situated at an elevation between EL. +6.5m and EL. +7.5m, with a total site area of approximately 116.02 hectares. The plant extends about 2,300 meters north to south and 750 meters east to west.
To meet the long-term electricity demand of northern Taiwan, this project was planned for the construction of new facilities, including pump houses and inlet/outlet culverts, to support three additional gas-fired combined cycle units (Units 7, 8, and 9) with a total installed capacity of 2,880–3,168 MW.

Project Overview and Features

The project site lies between the coastal protection forest on the western side of the power plant and the Taiwan Strait. The site is intersected by Provincial Highway 61 (West Coast Expressway) and Highway 66, while to the east lies Provincial Highway 15 and residential areas, and to the south the Xinwu River. The old Xiaofanli Creek also flows through the construction site. The geology consists mainly of sandy gravel and silty gravel, with some areas of backfill.
Given the large project area and the urgency of water intake and discharge commissioning, seven work zones were planned for simultaneous construction. The main works include construction of pump houses, inlet/outlet culverts, surge towers, cable conduits, and the supply and installation of hydro-mechanical equipment.

Project Benefits

This project addresses the chronic power shortage in northern Taiwan, which previously required electricity transmission from the south. It will increase generation efficiency from 37% in conventional thermal power plants to over 60%. With a total installed capacity of 7.2 million kW, the project ensures alignment with the government’s energy transition policy goals of achieving a nuclear-free homeland by 2025 and raising the share of natural gas generation to 50%.
