At the capacity of 4,384 MW, the plant is the world's largest gas turbine combined cycle power plant and Taiwan's largest gas-fired power plant.
Details
- Units 1 & 2, 742.7 MW ea, have a total of six Mitsubishi M501F combustion turbines (3 per unit) with two Mitsubishi 282 MW steam turbines. The combustion turbines were upgraded with low-NOx FMk8 model combustors and improved turbine blades in 2018. {{cite web|date=23 September 2020|url=https://www.power-technology.com/projects/datan-power-plant-expansion-taoyuan/|title=Datan Power Plant Expansion, Taoyuan|access-date=3 November 2022}}
- Units 3-6, 724.7 MW ea, have a total of eight Mitsubishi M501G combustion turbines (2 per unit).{{cite web |title=Mitsubishi Power Receives Serial Contracts from Taiwan Power for Large-Scale Modification of GTCC at the Datan Power Plant |url=https://power.mhi.com/news/20220705.html |website=power.mhi.com |publisher=Mitsubishi Group |access-date=20 April 2023 |archive-url=https://web.archive.org/web/20221103201619/https://power.mhi.com/news/20220705.html |archive-date=November 3, 2022 |language=en |date=2022-07-05 |url-status=live}}
- Unit 7 has two General Electric simple cycle 300 MW combustion turbines. The project was awarded in 2016. It is being converted to combined cycle, which will add 300 MW capacity to the unit upon completion in 2024.
- Units 8 & 9 have four General Electric 7HA.02 combustion turbines (two per unit). The project was awarded in 2019 with commissioning scheduled for 2022 (Unit 8) and 2023 (Unit 9).{{cite web |title=DaTan Combined-Cycle Power Plant Expansion |url=https://www.nsenergybusiness.com/projects/datan-combined-cycle-power-plant-expansion-taiwan/ |access-date=3 November 2022}}
When complete, the expansions currently underway will bring Tatan to a total capacity of 7,546 MW.
Architecture
The power plant spans over an area of 116.02 hectares with a length of 2,300 meters and width 750 meters.{{cite web|date=12 February 2021|url=https://www.taipower.com.tw/en/page.aspx?mid=4508&cid=2926&cchk=3a81685f-6f67-411e-aef5-aed5bb83d896|title=Datan Combined Cycle Power Plant Expansion Project|website=Taipower|access-date=6 December 2021}}
Fuel supply
The plant operates with liquefied natural gas supplied by CPC Corporation from Taichung LNG Terminal.{{cite web|url=http://focustaiwan.tw/news/aeco/201708150032.aspx|date=15 August 2017|first1=Yi-chu|last1=Tsai|first2=Cheng-wei|last2=Chen|first3=S.C.|last3=Chang|title=Taiwan's power supply system unable to withstand minor errors: expert|publisher=Focus Taiwan|accessdate=16 August 2017}}{{cite news|author=OGJ editors|date=18 July 2009|url=https://www.ogj.com/pipelines-transportation/lng/article/17277791/cpc-inaugurates-taiwans-second-lng-terminal|title=CPC inaugurates Taiwan's second LNG terminal|work=Oil&Gas Journal|access-date=1 December 2021}}
Events
=2005=
On 16 December 2005, the power plant combined cycle Unit 1 and 2 with a capacity of 435.9 MW each went into commercial operation.{{cite web|url=http://www.taipower.com.tw/e_content/content/events/events01-1.aspx?sid=7|title=Taiwan power company-Taipower Events|publisher=taipower.com.tw|accessdate=2014-08-22}}
=2009=
On 31 December 2009, the power plant combined cycle Unit 4 and 5 were converted from low pressure to high pressure and started commercial operation on the day. This conversion increased the plant capacity by 507.4 MW.
=2012=
In 2012, the power plant carried out the Guidance Plan for Energy Industry Adaptive Action in Response to Climate Change to conduct an analysis on the impact of climate change, a vulnerability check and risk evaluation for the facilities within their domain.{{cite web|url=http://www.taipower.com.tw/e_content/content/report/..%5C..%5C..%5CUpFile%5CCompanyENFile%5C2013Taipower_English_EBook.pdf|archive-url=http://arquivo.pt/wayback/20160517054834/http://www.taipower.com.tw/e_content/content/report/..%5C..%5C..%5CUpFile%5CCompanyENFile%5C2013Taipower_English_EBook.pdf|url-status=dead|archive-date=17 May 2016|date=20 December 2013|title=Taiwan Power Company Sustainability Report 2013|accessdate=2014-08-22}}

On 15 August 2017 at 4:52 p.m., the six generators of the power plant fully tripped due to operation technical error, disrupting the supply of 4 GW of electricity. During the power supply equipment replacement for a control system of the plant's metering station, the worker did not switch the system from auto mode to manual mode before starting the work, resulting the two gas supply pipe valves closed and stop the supply of liquefied natural gas fuel source for two minutes.{{cite web|url=https://www.bloomberg.com/news/articles/2017-08-16/taiwan-s-president-apologizes-for-blackout-affecting-millions|date=16 August 2017|title=Mishap Triggers Taiwan Blackout as Power Policies Draw Scrutiny|publisher=Bloomberg|accessdate=16 August 2017}}{{cite web|url=http://focustaiwan.tw/news/aeco/201708150033.aspx|date=15 August 2017|first1=Yu-yang|last1=Liao|first2=Ko|last2=Lin|title=Electricity supply restored around Taiwan: Taipower|publisher=Focus Taiwan|accessdate=16 August 2017}} Electricity rationing was implemented at 6:00 p.m. and ended at 9:40 p.m.{{cite web|url=http://focustaiwan.tw/news/aeco/201708150019.aspx|date=15 August 2017|first1=Yu-yang|last1=Liao|first2=Chung-han|last2=Kuo|title=Power outage across Taiwan due to malfunction at power plant|publisher=Focus Taiwan|accessdate=15 August 2017}}{{cite web|url=http://www.chinapost.com.tw/taiwan/2017/08/15/500029/live-updates.htm|date=15 August 2017|title=LIVE UPDATES: Power outages hit Taiwan|publisher=The China Post|accessdate=15 August 2017}} The outage hit northern half of Taiwan Island, affecting 6.68 million households.
