Recently, the powerhouse unit project of the Yellow River Yangqu Hydropower Station, constructed by Sinohydro Bureau 3 Co., Ltd., successfully passed acceptance, marking the full completion of the station's main works and the project's official transition from the construction phase to the full operation phase.

After inspecting the project site, reviewing project documentation, and hearing work reports from all participating units, the acceptance committee held thorough discussions and unanimously concluded that the powerhouse unit project of the Yellow River Yangqu Hydropower Station has been fully completed in accordance with contractual agreements and design requirements, with standardized construction processes and excellent quality, and that all indicators meet national and industry standards; acceptance was therefore approved.

The Yellow River Yangqu Hydropower Station is located at the border between Xinghai County and Guinan County in Hainan Tibetan Autonomous Prefecture, Qinghai Province. It is an important supporting peak-shaving power source for China's first ±800 kV "Qingyu DC" ultra-high-voltage transmission corridor and an important supporting power source for the Hainan Prefecture ten-million-kilowatt new energy base. The station has a total installed capacity of 1.2 million kilowatts and achieved full-capacity grid connection and power generation on December 26, 2024. The station was surveyed and designed by Northwest Institute under Power Construction Corporation of China (PowerChina), constructed by Sinohydro Bureau 3, Sinohydro Bureau 4, and Sinohydro Bureau 11, and supervised by Beijing Institute.

The powerhouse project is the core and key element of the Yangqu Hydropower Station construction. Since commencement, the project team has organized meticulously and managed scientifically. All builders have overcome numerous challenges, including complex geological conditions, high technical difficulty, and tight schedules, actively promoted and applied new technologies and new processes, and strictly controlled all aspects of safety, quality, and progress, achieving high-quality and efficient project advancement and ensuring the successful completion of the powerhouse unit project. The project team will efficiently advance follow-up completion work and special projects such as soil and water conservation, continue to carry out environmental protection work including slope treatment and vegetation restoration, and contribute more PowerChina strength to ecological protection and high-quality development in the Yellow River Basin.

Upon completion, the station will generate an average annual power output of 4.732 billion kWh, sufficient to meet the annual electricity demand of approximately 1.58 million households, equivalent to saving about 1.467 million tons of standard coal and reducing 4.412 million tons of carbon dioxide annually, with significant economic and ecological benefits. At the same time, it will effectively ensure full-load power transmission on the "Qingyu DC" ultra-high-voltage transmission corridor and provide strong support for promoting the large-scale development and application of new energy in Qinghai Province and building a clean energy base in the upper reaches of the Yellow River.
