Ownership Tree

This ownership tree is part of the Global Energy Ownership Tracker, a project of Global Energy Monitor.

Background

The two first coal-fired power units of Shuanghuai power station, totaling 600 MW, were brought online in 2006. The plant was owned by CPI and Chongqing Energy Investment Group.[5]

Second Phase

The plant's owners planned to build two additional coal-fired units at this plant, with a total planned capacity of 1,320 MW as of 2014.[6][7][8][9]

Units 3 and 4 were completed in June 2013 and September 2014 respectively.[10] [11][12]

Third Phase

According to a 2023 EIA document linked on the SPIC website and available in the Baidu Cloud, a third phase may have been under consideration since 2013 and on hold until the end of 2022, when it was revived to satisfy electricity demand from Chongqing. In November 2022, the Chongqing DRC issued a "Letter on Accelerating the Promotion of the Hechuan Shuanghuai Phase III Coal-fired Power Project."[13] In December 2022, the SPIC Chongqing Hechuan Power Generation Co., Ltd. entrusted Chongqing Huankeyuan Boda Environmental Protection Technology Co., Ltd. to carry out the environmental impact assessment,[14] and the Energy Bureau issued a notice regarding the expansion in the City's 14th Five-Year Electricity Development Plan. The project was featured in Chongqing's key projects list for 2023 under new construction.[15]

The expansion was permitted on March 4, 2023 (渝发改能源【2023】284号) according to the EIA report.[13] In April 2023, a pre-announcement regarding land acquisition was also circulated.[16]

In July 2024, project progress was reported. In September 2024, a framework agreement was signed. In October 2024, a mobilization ceremony was held. In February 2025, the project was listed in the 2025-2027 planned construction list.

In April 2025, the project owner and name changed. In May 2025, survey and design bidding began. In June 2025, the survey and design contract was awarded. In July 2025, major equipment bidding commenced. In August 2025, major equipment bids were awarded. In September 2025, site preparation and supervision bidding occurred. The "五通一平" ceremony was held in September 2025[17]. In November 2025, the project commenced with a ceremony. In December 2025, the desulfurization system contract was awarded.

In March 2026, main construction and installation bids were awarded. In April 2026, Unit 1 boiler foundation concrete was poured[18]. In July 2026, major piping contracts were awarded.

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.[19]
