Overview
Sinohydro (中国水电) is a Chinese state-owned enterprise brand engaged in hydropower and civil engineering construction, and is among the world's largest international contractors in the hydropower sector. It is the international business flagship and a subsidiary of the Power Construction Corporation of China (PowerChina), a Fortune Global 500 company. Sinohydro Corporation Limited is the bearer of the SINOHYDRO brand. The brand traces its origins to 1950 and is headquartered in Beijing. It is well known as China's first brand in hydropower construction, having been responsible for 65% of large and medium-scale hydropower stations in China. Over more than 60 years of development, it has built diversified operations in over 100 countries, covering almost all areas of the construction sector, including energy, transport, water works, civil engineering and building. Sinohydro offers package solutions through project models ranging from simple construction to EPC and BOT. Its business portfolio spans water and hydropower facilities, airports, roads, ports and housing projects. According to its official website, it has 486 international projects under construction in more than 72 countries, with a total contract value of nearly USD 43 billion. Its services also cover electric power investment and real estate, design and manufacture of construction equipment, project financing, consulting, and mechanical/electrical installation. In 2025, its parent PowerChina was ranked No. 6 and No. 8 on the ENR lists of Top 250 Global Contractors and Top 250 International Contractors respectively. In the 2012 Engineering News-Record Top 225 Global Contractors list, Sinohydro ranked 14th globally and 6th among Chinese firms. The company's European regional headquarters is located in Belgrade, Serbia. Sinohydro has been involved in numerous notable international projects, including the Padma Bridge river training works in Bangladesh, the Tarbela IV Extension in Pakistan, the Port of Hambantota and Moragahakanda Dam in Sri Lanka, the Zungeru and Karuma hydropower stations in Nigeria and Uganda, the New Hamad Port in Qatar, the Coca Codo Sinclair Dam in Ecuador, and the Río Blanco dam in Honduras. On March 10, 2016, Sinohydro's international business functions were merged with those of HydroChina to form POWERCHINA International.
History
Sinohydro was established in 1950 within China's state water-resources and hydropower construction system. Its formative work centered on the construction of dams, hydropower facilities, water-management works, and related civil infrastructure. During the late 1950s, predecessor organizations also undertook construction connected with China's foreign economic-aid and diplomatic initiatives, giving the organization early experience outside the domestic market. During the 1980s, HydroChina Corporation was authorized to conduct foreign economic and technological cooperation. This authorization provided a foundation for a more commercially organized overseas business. On April 10, 1993, Sinohydro received foreign-trade rights, allowing it to develop international contracting and equipment-related activities more directly. The company subsequently pursued a standardized overseas operating model. In 2000, it adopted a four-unities strategy covering unified management, unified resource allocation, unified branding, and unified external cooperation. The company broadened its technical scope after 2004. In addition to hydropower, it participated in thermal, solar, and wind-power projects and developed capabilities in investment, consulting, financing, equipment production, and mechanical and electrical installation. Its civil-engineering portfolio also expanded to roads, railways, ports, municipal works, industrial projects, and buildings. This diversification allowed Sinohydro to compete for integrated infrastructure packages rather than only for dam construction. International expansion accelerated through the 2000s. By the end of 2010, Sinohydro had 69 overseas offices in 53 countries and 261 projects in 57 countries. Representative work cited in public reference material included river-training works for Bangladesh's Padma Bridge, the Tarbela IV Extension Project in Pakistan, hydropower projects in Nigeria and Uganda, port infrastructure in Qatar, road work in Georgia, and renewable-energy installations in several markets. The company also participated in major projects in Sri Lanka, Iran, Indonesia, Tunisia, Israel, and other countries. In 2011, Power Construction Corporation of China, commonly known as PowerChina, was created with State Council approval. The new group consolidated 105 subsidiaries, including Sinohydro, and provided a broader organizational platform for power engineering, construction, investment, and international operations. Sinohydro continued to operate through subsidiaries and affiliates such as Sinohydro Ltd and Sinohydro Consulting. Its global scale was reflected in its fourteenth-place ranking in Engineering News-Record's 2012 Top 225 Global Contractors list. On March 10, 2016, Sinohydro's international business functions were merged with those of HydroChina to form POWERCHINA International. The reorganization strengthened group-level coordination of overseas business while preserving Sinohydro as a prominent engineering and construction identity. The brand's contemporary role is therefore linked to PowerChina's broader platform, with particular recognition in hydropower, water infrastructure, large civil works, and international EPC delivery. The company's projects have also generated controversy where dams or other infrastructure affect land, ecosystems, and local communities. The Río Blanco dam project in Honduras is one example identified in public reference material as controversial. Such cases form part of the environmental and social debate surrounding large infrastructure contractors, but the available material does not provide enough detail to characterize them as adjudicated corporate scandals.

Products and positioning
A state-owned, internationally oriented engineering and construction provider specializing in hydropower, water infrastructure, energy, and large civil-engineering projects.
Energy infrastructure · 1950
Hydropower and dam construction
Sinohydro's core capability covers the engineering, procurement, construction, and related civil works required for dams, hydropower stations, river diversion, tunnels, reservoirs, and associated power infrastructure. This specialization is the foundation of the brand's international reputation and remains closely connected to its broader water-resources and energy business.
Energy infrastructure · 2004
Renewable-energy projects
From 2004 onward, Sinohydro expanded into solar and wind projects in addition to its established hydropower activities. The offering includes construction and engineering support for utility-scale generation facilities and can be combined with the group's wider power, transmission, civil works, and investment capabilities.
Water infrastructure · 1950
Water-conservancy engineering
Water-conservancy work includes river management, dam-related infrastructure, diversion systems, flood-control works, irrigation-related construction, and river-training packages. These services draw on the company's historical engineering base and are often delivered as part of larger transport, urban, or power projects.
Engineering and construction · 1993
International EPC and civil engineering
Sinohydro provides integrated engineering, procurement, and construction services for large infrastructure programs. Its scope extends beyond power to roads, railways, ports, municipal facilities, buildings, and industrial works, allowing the company to act as a main contractor or package contractor in international markets.
Professional engineering services · 1980
Consulting, financing, and technical services
Through specialist affiliates and group capabilities, Sinohydro's business includes engineering consulting, project financing support, mechanical and electrical installation, and technical coordination. These services help connect feasibility, design, construction, and commissioning within large infrastructure developments.
Controversies
Controversy surrounding the Río Blanco dam project
Sinohydro participated in construction of the controversial Río Blanco dam in Honduras. The project became associated with broader disputes concerning environmental effects, indigenous and community rights, and infrastructure development. The available reference does not establish a final legal finding against Sinohydro, so the matter is recorded as a project controversy rather than a proven corporate violation.
