Background
Mawan power station is a six-unit coal-fired power plant with a total capacity of 1,840 MW.[16] The plant was completed between 1993 and 2003, and is majority-owned by Shenzhen Energy Group.[17]
A 681 MW gas-fired power plant is expected to start operation in 2025 to replace the coal-fired units.[18] This project received approval from the Development and Reform Commission on February 16, 2022. [19]Construction officially began in September 2022, and it is expected to commence operation in June 2024.[20]
Units 1 and 2 were retired in November 2024[21].
The replacement units (Replace Unit 1 and 2) had a project approval public notice in September 2024[22], and the project was approved on September 27[23]. In November 2024, a tender for main machinery was issued[24], with the contracts awarded in January 2025[25].
In February 2025, the boiler contract was awarded[26], and the main machinery contracts were signed in March[27]. In May, a tender for survey and design supervision was issued[28], and the contract was awarded in June[29]. A feasibility study review for the second phase was held in June[30]. In July, a tender for construction supervision was issued[31], and the contract was awarded in August[32]. A commencement ceremony was held on August 23, with piling works formally starting[33]. In September, tenders for the chimney and main building installation were issued[34][35]. The chimney project commenced in December 2025[36], and the main building installation contract was signed later that month[37].
In January 2026, chimney foundation concrete pouring began[38]. In June, the first boiler steel frame for Unit 9 was hoisted[39].
