Last updated October 9, 2026
Overview
China Three Gorges Corporation (CTG) is a Chinese state-owned power company established on 27 September 1993. It is best known as the entity responsible for the construction of the Three Gorges Dam project, the world's largest hydroelectric power plant, which went into operation in 2008. In September 2002, CTG established the subsidiary China Yangtze Power, which took over operations and management of the Gezhouba and Three Gorges dams. CTG is one of the world's largest energy companies, with total assets of RMB 475.5 billion (approximately USD 77.3 billion) in 2014. Beyond hydroelectric dams, CTG operates onshore and offshore wind farms. It operates and develops other hydroelectric projects on the Yangtze River, including the Xiangjiaba Dam, Xiluodu Dam, Baihetan Dam (the world's second largest hydroelectric power plant) and Wudongde Dam. By the end of 2014, CTG had 46.3 GW of total hydropower installed capacity in China and over 28 GW of total installed capacity under construction or development. CTG started to develop wind power in 2007 and entered the solar power industry in 2011. By 2014, it had 31 wind power projects in operation and 33 under construction or development, as well as 37 solar power projects in operation and 18 under construction or development. Total installed capacity at the time was 3,707 MW in operation, with 3,050 MW under construction or development. As of the end of 2013, CTG had business in 37 countries and regions, with 84 ongoing international construction and investment projects. In December 2011, China Three Gorges Corporation acquired a 21.35% Portuguese government stake in Energias de Portugal for €2.69 billion. In the same month, it paid HK$2.1 billion (US$270 million) for a 29% stake in China Power New Energy Development. China Yangtze River Three Gorges Corporation is also involved in developing, building, and operating hydroelectric power facilities in Brazil. In August 2020, the United States Department of Defense published the names of companies with links to the People's Liberation Army operating directly or indirectly in the United States, and CTG was included on the list. In November 2020, Donald Trump issued an executive order prohibiting any American company or individual from owning shares in companies that the United States Department of Defense has listed as having links to the People's Liberation Army, which included CTG. In January 2024, the United States Department of Defense named CTG on its list of "Chinese Military Companies Operating in the United States."
History
The institutional history of China Three Gorges Corporation is tied to China's long-running effort to develop the Three Gorges Project on the Yangtze River. Proposals for a major dam in the Three Gorges region had circulated since the twentieth century, but the project became a national infrastructure priority in the late 1980s and early 1990s. In 1993, the Chinese government established China Three Gorges Project Corporation as the principal organization responsible for project development, financing, construction and operation. The enterprise was later reorganized and renamed China Three Gorges Corporation. The corporation's initial mission was concentrated on the Three Gorges Dam and hydropower station in Hubei. Construction involved large civil works, ship locks, power-generation equipment and the progressive relocation of communities from areas that would be inundated by the reservoir. The project was justified by its expected contributions to flood control, electricity supply and navigation on the upper and middle Yangtze. At the same time, government reviews, academic studies and public debate highlighted the scale of resettlement and potential effects on ecosystems, sediment movement, cultural heritage and downstream river conditions. The reservoir began filling in stages during the 2000s. The first generating units entered service during that decade, and the final planned units of the main hydropower station were completed in 2012. The completed facility made CTG one of the world's most prominent hydropower operators. The group also remained involved in the operation of the nearby Gezhouba project and gradually expanded its role across the Yangtze basin. During the 2000s and 2010s, CTG developed a larger corporate structure through China Yangtze Power and other subsidiaries. China Yangtze Power became the principal listed operating company for important Yangtze hydropower assets, including the Three Gorges, Gezhouba, Xiluodu and Xiangjiaba stations. This arrangement separated some listed asset ownership and operating functions from the unlisted state-owned parent while allowing CTG to retain strategic control over a large generation portfolio. The group then broadened its business from conventional large hydropower to wind, solar, pumped storage, ecological management and related engineering services. This diversification reflected both China's growing electricity demand and national policies favoring low-carbon generation. CTG's renewable-energy activities include project development, asset investment and operation, with wind and solar becoming increasingly important alongside its hydropower base. International investment became a defining part of CTG's later development. In 2011, the group acquired a controlling stake in Energias de Portugal, or EDP, after Portugal's privatization process. The investment gave CTG exposure to electricity generation, distribution and renewable energy in multiple markets. CTG and associated entities have subsequently participated in energy projects and partnerships in Brazil, Pakistan, Turkey, Africa, Southeast Asia and other regions. These activities made the group an important example of Chinese state-backed infrastructure investment abroad. In the 2020s, CTG continued to present itself as a clean-energy enterprise supporting China's energy transition. Its strategic priorities have included large renewable bases, flexible generation, pumped storage, digitalized operations and improved ecological management around major water projects. The group remains closely connected to national energy and infrastructure policy. Its record is also assessed through debates about the social and environmental consequences of large dams, reservoir management during extreme weather, overseas investment governance and the role of state-owned enterprises in domestic and international power markets.

Products and positioning
A central Chinese state-owned clean-energy and infrastructure group centered on hydropower, large-scale renewable generation and international electricity investment.
Hydropower · 2003
Three Gorges Hydropower Station
CTG's signature project on the Yangtze River in Hubei Province. The dam and power station combine electricity generation with major flood-control and navigation infrastructure. Its large reservoir and generating fleet made it a central component of China's inland power system and the defining asset of the CTG brand.
Hydropower
Yangtze River hydropower portfolio
The group and its listed subsidiary China Yangtze Power operate a series of major stations in the Yangtze basin, including Gezhouba, Xiluodu and Xiangjiaba. Together these assets extend CTG's expertise from the Three Gorges site to a broader river-basin generation and water-management system.
Renewable energy
Wind and solar generation
CTG develops and operates utility-scale wind and photovoltaic projects in China and overseas. These businesses diversify the group beyond large dams and support its positioning as a clean-energy company aligned with China's expansion of non-fossil electricity.
International electricity investment · 2011
EDP international platform
CTG's controlling investment in EDP provided exposure to electricity generation, distribution and renewable-energy operations across several countries. The investment became a principal channel for the group's international expansion and helped connect its Chinese hydropower expertise with overseas power markets.
Energy storage and grid flexibility
Pumped-storage power
Pumped-storage projects form part of CTG's effort to provide flexible capacity for grids with growing wind and solar penetration. These facilities store electricity by moving water between reservoirs and can support peak demand, frequency management and renewable integration.
Controversies
2006
Three Gorges resettlement and environmental controversy
The Three Gorges Project attracted sustained criticism concerning the scale and administration of population resettlement, the loss of cultural and archaeological sites, ecological disruption, sediment and downstream impacts. These issues concern the project and its governance rather than a single confirmed corporate misconduct event.
