Project-level coal details
- Coal source(s): domestic
Background
Tongliao power station is a seven-unit coal-fired power plant with a total capacity of 1,670 MW. The plant was completed between 1985 and 2006, and was originally owned by CPIC.[5]
Units 8 and 9 were commissioned in 2025. In 2023, construction was ongoing with boiler board beams installed and the project on Inner Mongolia's key list.[6]
Capacity replacement proposed
In 2021, a 2 x 350 MW capacity replacement project was proposed (国家电投通辽2×350MW智慧热电联产机组). Unit 1 to 4 (4 x 200 MW) were proposed to be retired once the new capacity is complete. Preparation work was reportedly done, although a permit was needed to start construction.[7]
The ultra-supercritical capacity was permitted in May 2022.[8]
It was reported that construction began on Units 8 and 9 in April 2023.[9] On 15 May 2023, the first steel frame of the unit 9 boiler was successfully hoisted into place after pouring concrete for the main structure of unit 8. Construction was estimated to be completed in 2024.[10]
In 2024, key milestones such as chimney topping, turbine cylinder closure, and power-on were achieved.[11]
The units successfully passed their 168-hour trials in May 2025.[12][13]
Ownership
In July 2015, China Power Investment Corporation (CPI) and State Nuclear Power Technology Corporation (SNPTC) merged to become State Power Investment Corporation (国家电力投资集团), one of the five largest state-owned electricity producers in the People's Republic of China.[14]
