1.　Thermal Power Project

●　Tatan Combined-Cycle Project

The project is to install two 742.7 MW oil/gas-fired units by October 2006 and four 724.7 MW gas-fired units by December 2008, with a total capacity of 4,384 MW. The simple cycle units 1＆2 were qualified for commercial operation in June and November 2006, respectively. The rest will start commercial operation at the end of 2008. As of the end of December 2006, the project was 60.98% complete, slightly ahead of schedule.

●　Taichung Thermal Units 9 & 10 Project

Taipower plans to install two 550 MW, in total 1,100 MW, coal-fired units in the Taichung Thermal Power Plant by June 2007. Unit 9 started commercial operation in June 2005. Unit 10 started commercial operation in June 2006. Up to the end of 2006, the project was 99.62% complete.

●　Linkou Replacement and Expansion Project

This project is to install three 800 MW supercritical coal-fired units before June 2019. They are scheduled for commercial operation in January and July 2012, and February 2017, respectively. As of the end of 2006, the project was 0.1% complete and on schedule.

2.　The Nuclear Power Project

●　The Fourth Nuclear Power Project

Through open tender, General Electric Company of the United States won the bid for two advanced light water reactors, 1,350 MW each, and the provision of nuclear fuel in May 1996. Mitsubishi Heavy Industry Ltd. of Japan won the bid for turbine generators in October 1996.

Foundation excavation for reactor building started on January 10, 1998. The Atomic Energy Council of the Executive Yuan issued construction permit for the project in March 1999. The Unit 1 Reactor Pressure Vessel was set on March 20, 2005 and Unit 2 on October 5, 2006.

Because the construction progress is behind schedule, Taipower reported to the Executive Yuan to revise the commercial operation dates to July 2009 and July 2010 (from July 2006 and July 2007), respectively.

3.　Hydro Power Projects

●　Kukuan Hydro Power Plant Rehabilitation Project

Owing to the aftermath of the Taotze typhoon that occurred on July 30, 2001, the Kukuan Hydro Power Plant was filled with debris and water. The power facilities were severely damaged and were out of operation.

Rehabilitation work includes the extension of the existing tailrace and the construction of the power access tunnel, generation units and main
transformer. This project started in April 2002 and is scheduled for commercial operation in June 2008. The installed capacity will increase from 180 MW to 212.8 MW. As of the end of December 2006, the project was 70.36% complete and 0.04% ahead of schedule.

●　Wanta Expansion and Sunglin Hydro Power Project

(1) Wanta Expansion Hydro Power Project 

This project is to build an intake at about 300 meter upstream from the right bank of the Wushe Dam. The water will run through a 57-meter headrace tunnel and a 305-meter penstock to the downstream Wanta Hydro Power Plant. A vertical Francis turbine generation unit (19.7 MW, and having an annual production of 46.45 GWh) will be installed in this half-underground powerhouse.

(2) Sunglin Hydro Power Project 

A weir will be constructed 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-meter 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, respectively, and having an annual production of 78.8 GWh) will be installed.

The Wanta Expansion and Sunglin Hydro Power Project started in September 2004 and its commercial operation will begin in July 2011. As of the end of 2006, the project was 11.87% complete. 

●　Bihai Hydro Power Project

The project utilizes the water resources available from the Hoping River basin in Hualien County, in eastern Taiwan. An underground type powerhouse with one vertical Pelton turbine unit, 61.2 MW, will be installed. This project is scheduled for commercial operation by December 2007 and it will add 237 GWh to the company's production per year. As of the end of December 2006, this project was 76.9% complete.

●　Shibao Hydro Power Project

The project is located at the Wanli Creek, a tributary of the Hualien River in eastern Taiwan. The powerhouse will be an underground reinforced concrete building. Two vertical Francis turbine generation units, 63.0 MW and 11.2 MW, will be installed to produce total energy of 288 GWh per year. The project is scheduled for commercial operation in January 2009. The project has been suspended as its 2005 budget was cut by the Legislative Yuan (Parliament).

4.　Wind Power Project

●　First Phase (January 2003-December 2007)

Taipower plans to install 60 units with a total capacity of 98.96 MW on a number of sites including the Shimen, Tatan, Kuangyuan, Hsianshan, Taichung Harbor, Taichung and Hengchun Power Stations.

Among them, the Shimen, Tatan and Kuangyuan Wind Power Stations were completed and are in commercial operation. The others are scheduled for commercial operation by the end of 2007.

●　Second Phase (January 2005-April 2008)

Taipower plans to install 58 units with a total capacity of 116 MW at a number of sites including the Changgong, Yunlin Mailiao, Sihu and Linkou Wind Power Stations. Among them, the Changgong (2,000 KW x 23) is scheduled for commercial operation in early 2007. The Yunlin Mailiao (2,000 KW x 15) is scheduled for commercial operation in 2009. For the Sihu (2,000 KW x 14) and Linkou (2,000 KW x 6), the bid winner(s) will be awarded in March 2007.

●　Third Phase (January 2007-June 2011)

Taipower plans to install 52 units with a total capacity of 104 MW in the following sites: Tatan, Changgong, Changhwa Wanggong and Yonghsin, Yunlin Mialiao and Tainan Haishencho. They are scheduled for commercial operation between 2008 and 2020.

5.　The Sixth Transmission and Distribution Project

To comply with power development program and regional load growth, Taipower formulated the Sixth Power Transmission and Substation Project. After revision, the project started in July 2001 and is scheduled for completion in December 2009.

The project plan is to install 292 new substations, a total capacity of 71,791 MVA of new and expanded substations and a total length of 4,185 ckt-km transmission lines. The budget of this project is NT$389.9 billion.

In 2006, Taipower completed a total installation capacity of 6,781 MVA of substations and a total length of 499 ckt-km of transmission lines, of which 227 ckt-km are overhead lines and 272 ckt-km underground cables.

The major accomplishments in 2006 were：
    ● 4 EHV substations.
    ● 2 primary substations.
    ● 20 primary distribution substations.
    ● 2 generation substations.
    ● 3 secondary substations.
    ● 54 ckt-km of 345 KV transmission lines.
    ● 368 ckt-km of 161KV transmission lines.
    ● 77 ckt-km of 69 KV transmission lines.
    
When the completion of a new substation is delayed or the power consumption in a region exceeds estimates, measures of expansion will be undertaken to fulfill the urgent demand. In 2006, the total expansion capacity was 1,921 MVA, accounting for 28.3% of the newly added capacity. This accomplishment was a great help to stabilize power supply and ensure power supply quality.

6.　The Fifth Distribution Project

In order to increase power distribution reliability and power supply quality, Taipower launched various distribution projects to strengthen its distribution system. The Fifth Distribution Project started in July 2003 and is scheduled for completion in December 2007. The total budget for this project is NT$72.1 billion.

Up to the end of 2006, total budgetary expenditure has reached 48.5 billion. The project was 81.17% complete. Three expanded substations were constructed. The capacity of main transformers was 75 MVA. New, expanded and improved distribution lines reached 2,547.55 cktkm, of which overhead lines was 465.24 ckt-km and underground 2,082.31 ckt-km. The replaced and added transformers reached 3,401.51 MVA, electricity meters reached 544,754 units, and 721 feeders were automated.
