Background
Yiyang power station was originally a four-unit coal-fired power plant with a total capacity of 1,920 MW. The plant was completed between 2000 and 2008, and is majority-owned by Shaanxi Coal and Chemical Industry Group.[4][5]
Expansion
In July 2019, it was reported that a 2 x 1,000 MW expansion at the power station was planned and included in the "14th Five-Year Plan for Electric Power Development" of Hunan Province (2021-2025). Pre-feasibility studies were underway.[6]
According to a job announcement, the units were permitted on December 30, 2021.[7]
Construction reportedly began on July 25, 2022.[8]
Phase III Unit 5 saw construction progress in 2023, with the cooling tower V-shaped columns hoisted in July[9]. In 2024, the cooling tower was capped in May[10], the generator rotor was inserted in August[11], the plant power system was energized in October[12], and the unit was connected to the grid in December[13]. In February 2025, the unit passed the 168-hour trial[14].
Phase III Unit 6 had the boiler heating surface welded in December 2023[15]. In 2024, the low-pressure heater was hoisted in July[16], the generator stator was hoisted in October[17], the boiler hydraulic test passed in November[18], and the plant power system was energized in December[19]. In March 2025, flushing was completed[20], the unit was connected to the grid in April[21], and passed the 168-hour trial, entering commercial operation in May[22].
