Nuclear and Thermal Power Projects

■ Nuclear Power Project

● The Fourth Nuclear Power Project

The Fourth Nuclear Power Project adopts two 1,350 MW Advanced Boiling Water Reactor (ABWR) units supplied by GE- Hitachi Nuclear Energy Americas LLC. Foundation excavation for the Reactor Building started on January 10, 1998. The Atomic Energy Council issued a Construction Permit for the Project in March 1999. The total investment for this project is NT$ 273.6 billion.

The following milestones have been achieved: Unit 1 Reactor Pressure Vessel (RPV) Setting (March 20, 2005), Unit 2 RPV Setting (October 5, 2006), Unit 1 161kV Energized (July 15, 2007), Unit 1 RPV Hydro Test (November 1, 2008), Unit 1 Emergency Core Cooling System Core Injection (April 30, 2010), Flow-Induced Vibration Test (September 12, 2010), Unit 1 345 kV Energized (October 28, 2010) and Unit 2 161 kV Energized (August 4, 2011). The Unit 1 is currently undergoing pre-operation testing.

■ Thermal Power Projects

For the purpose of energy conservation and carbon reduction, reducing air pollution, strengthening environmental protection, satisfying power demand growth, and satisfying reserve margin, the company has been undertaking the following thermal power projects:

● Changgong Thermal Units 1 and 2 Project

The project will involve installing two 800 MW ultra supercritical coal-fired units in the Changbin Industrial Park. They are scheduled for commercial operation in January and July 2018. As influenced by the schedule of an environmental assessment review, the progress of this project has stalled. At the end of December 2011, the project was 4.63 % complete.

● Tunghsiao Thermal Power Retrofit Project

The existing low-efficiency units will be replaced by new ones to satisfy the requirement of power demand growth. The project aims to install four 720 MW combined-cycle units. They are scheduled for commercial operation in July 2016, January 2017, July 2017 and January 2018, respectively. As of the end of December 2011, the task of the procurement of technical consultants was accomplished. The project was 0.16% complete.

● Shenao Thermal Power Plant Retrofit Project

This project aims to install two 800 MW ultra supercritical coal-fired units. The existing Shenao Thermal Power Plant is to be demolished first and then a new one will be constructed. The investment is estimated at NT$108.9 billion. As the construction of the coal-unloading pier came up against resistance from local people, the project was unable to carried out smoothly. According to Taipower’s 10009 Power Development Program, the commercial operation dates for Units 1&2 have been revised to April 2018 and April 2019. As of the end of December 2011, the demolition work has been accomplished and the project was 2.48% complete.

● Linkou Thermal Power Plant Retrofit Project

In order to maintain sufficient power supply and quality in northern Taiwan, the existing units are to be demolished and three 800 MW ultra supercritical coal-fired units will be installed. The total investment amount is NT$152.5 billion. Units 1 & 2 are scheduled for commercial operation in January 2016 and January 2017. After Unit 1 is in commercial operation, the existing Units 1 & 2 will be demolished and the installation of Unit 3 will start, which is scheduled for commercial operation in January 2021.

The EPC (engineering procurement & construction) contract for the major power facilities of this project was signed on December 7, 2011. As of the end of 2011, the project was 12.66% complete.

● Talin Thermal Power Plant Retrofit ProjectTalin Thermal Power Plant Retrofit Project

The project aims to install four ultra supercritical coal-fired units, 800 MW each, to replace the five low- efficiency ones. It adopted the pattern of demolition first and then installation. Originally, the Executive Yuan approved four units to be installed. However, as only two units passed the Environmental Impact Assessment (EIA), Taipower revised its project to include two units. The construction permit was issued by the MOEA on October 25, 2011.The investment is estimated at NT$119.2 billion for the two units. They are scheduled for commercial operation on July 1, 2016 and July 1, 2017, respectively. As of the end of December 2011, the project was 2.3% complete.

Hydro Power Projects

● Bihai Hydro Power Project

A concrete gravity dam was constructed along the Hoping River basin in Hualien County. The effective capacity of the reservoir is about 635,000 m 3 . An intake valve built within the dam is connected with a 6,549-meter long headrace tunnel. Water will flow along the tunnel to the underground power plant where a vertical Pelton turbine unit of 61.2 MW is installed. The project started commercial operation on December 10, 2011.

● Wanta Expansion and Sunglin Hydro Power Project

The installed capacity of the Wanta Expansion is 19.7 MW and the capacity of Sunglin Hydro is 20.9 MW. This project was started in July 2007. It is scheduled for commercial operation in October 2012. As of the end of 2011, the project was 86% complete.

● Tachiachi Hydro Power Plant Chingshan Branch Retrofit Project

The 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 on July 2, 2005. This led to a loss of 360 MW spinning reserve for fast response and a loss of frequency control in the power system, which seriously influenced the safety and frequency quality of the power system.

The project was started in November 2009 and is scheduled for commercial operation in December 2015. As of the end of 2011, the project was 22.12% complete. 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 GWh can reduce about 0.269 million tons of CO 2 emissions from gas-fired combined cycle units. This will greatly benefit carbon reduction and power supply stability.

Renewable Energy Power Development Projects

■ Wind Power Project

Since 2000, Taipower has completed the installation of 160 wind power units, totaling 284.76 MW, in the first 3 phases and the remote islets wind power project. All are currently in commercial operation, of which, Changhua Wanggong has10 units with a total of 23 MW, Linkou 3 units at 6 MW, and Tatan 5 units at 10.6 MW, were completed and started commercial operation in 2011. The Fourth Phase was approved in June 2011 and the implementation period is set to be from 2012 to 2015.

● First Phase (January 2003~December 2008)

With a total installed capacity of 98.96 MW, 60 units were installed and in commercial operation at a number of sites, including Shinmen (660 kW x 6), Tatan (I) (1500 kW x 3),Guanyuan (1500 kW x 20), Shianshan (2000 kW x 6), Taichung Harbor (2000 kW x 18), Taichung Power Plant (2000 kW x 4) and Hengchun (1500 kW x 3) Wind Power Stations.

■ Photovoltaic Project

The first phase of the photovoltaic project originally planned to install a 10 MW photovoltaic system by the end of 2011. The total amount of investment is about NT$3.57 billion. The sites designated for construction included Taipower-owned buildings and lands and the proper sites provided by outsiders. As of the end of 2011, 15 sites with a total installed capacity of 10.43 MW were synchronized to the power system.

Owing to a steep drop in the price of materials used in photovoltaic facilities, a surplus of NT$1.57 billion was left over from the investment amount of the First Phase. This project has been revised so that 9,200 kW will be added without increasing the total investment amount, and the project is now scheduled for completion at the end of 2014.
