Taean power station

From Global Energy Monitor

Taean power station (태안화력) is a 6,100-megawatt (MW) coal-fired power station in Chungcheongnam-do, South Korea.

The plant is #2 of the top ten largest coal plants in the world.

In addition, a 300 MW IGCC plant is located at the site.

Background on Plant

The existing power station consists of eight 500 MW units built from 1995-2007.[1] The 4,000 MW plant provides power to the South Korean capital and the surrounding regions and is located in Taeangun, Chungcheongnam-do, about 100km southwest of Seoul.[2]

According to the country's 8th Basic Plan for Long-Term Electricity Supply and Demand (2017-2031), finalized in December 2017, Taean power station Units 1-2 will be converted to burn gas instead. The date of the proposed conversion is not listed.[3][4] However, in the 9th Basic Plan released in 2020 a schedule is set to replace coal units 1-6 with LNG plants from 2025-2032.[5]

Description of Expansion

Units 9 and 10 of 1,050 MW each (2,100 MW total) are scheduled for completion in 2016.[6]

The new units were delayed due to accidents and defects. Before the completion of the project, the third stage of the turbine, which is the core cycle, was damaged and a fire occurred, delaying commissioning. Unit 9 was eventually completed in 2016, and Unit 10 is expected to be completed in 2017.[7]

Unit 10 was completed in 2017.[8][9][10]

Financing for Units 9 and 10

The project was financed through bonds from the following entities: National Pension Service (US$256,110,465), NH Investment Securities (US$137,215,245), Korea Post (US$18,295,366), and IBK Affiliates (US$54,883,766).[11]

Taean IGCC Project

The Taean IGCC Project is the first commercial integrated gasification combined cycle project to be built in South Korea. The project will produce syngas from low-BTU coal; the syngas will then be burned to generate electricity. As of 2014, the project was under construction and slated for start-up in late 2015.[12][13]

The IGCC plant is being considered for retrofit with carbon capture and storage technology by 2020, known as Korea-CCS2.[14]

On August 19, 2016, KEPCO announced the IGCC plant had begun operation.[15]
