■ Hydro Power Projects

1. Wanta Expansion and Sunglin Hydro Power Project

● Wanta Expansion Hydro Power Project

In order to fully develop and utilize the water resources between Wushe Dam and Wuchieh Dam, the project aims to build an intake about 300 m upstream from the right bank of the Wushe Dam. The water will run through a 61 m headrace tunnel and a 305 m penstock to the Wanta Hyudro Power Plant downstream. A vertical Francis turbine generation unit (19.7 MW) will be installed in this half-underground powerhouse.

● Sunglin Hydro Power Project

The project aims to construct a weir 400 m upstream from the confluence of Wushe River and Wanta River to collect the tailrace water from the Wanta Hydro Power Plant. The water will run through a 4.7 km headrace tunnel (to the front pond) and a 145 m penstock to the half-underground powerhouse. The tailrace water will then run into the Choshui Creek. Two vertical Francis turbine generation units (18.2 MW and 2.7 MW, totaling 20.9 MW) will be installed.

The Project was started in July 2007 and is scheduled for commercial operation in October 2012. As of the end of 2010, it was 70.46% complete.

2. Tachiachi Hydro Power Plant Chingshan Branch Retrofit Project

Chingshan Hydro Power Plant is Taipower’s largest conventional hydro power plant. The power plant was unable to operate after being damaged by the flood that occurred in July 2, 2005. This led to a reduction of 360 MW in the power system’s fast response spinning reserve and frequency control spinning reserve, which seriously influenced the safety and frequency quality of the power system. The major items of the project include: renovating the underground powerhouse, building a new underground switch yard by using SF6GIS equipment, extending the length of the tailrace tunnel about 2,093 m so that the tailrace water will run into Kukuan Dam for the Kukuan Hydro Power Plant’s power generation, establishing a length of 5,620 m communication tunnel, and replacing major generation equipment. Upon the completion of this project, the net peaking capability of the power system will be 368 MW. This power plant’s annual average power generation of 621.71 million KWh can reduce about 0.269 million tons of CO 2 emissions from gas-fired combined cycle units. This will greatly benefit energy conservation and carbon reduction and power supply stability. The major civil construction for this project was started in July 2010 and will be completed in December 2016. Four units are scheduled for commercial operation in December 2015. As of the end of 2010, the project was 9.47% complete.
