Recently, a consortium led by China Power Construction Corporation (referred to as "PowerChina") successfully won the bid for the EPC general contracting project of Xingtai Pumped Storage Power Station, with a bid amount exceeding 4.9 billion yuan and a total installed capacity of 1200 megawatts. The implementation of this major cooperation is not only another benchmark achievement of China Electric Power Construction in the field of pumped storage, but also injects strong impetus into the optimization of energy structure and green and low-carbon transformation in the Beijing Tianjin Hebei region.

A an important peak shaving, valley filling, energy storage and supply guarantee facility for the Beijing Tianjin Hebei power grid, Xingtai Pumped Storage Power Station plans to install four 300 MW reversible water pump turbine generator units, with an estimated total construction period of about 66 months. After the completion of the project, it will fully utilize the multiple functions of pumped storage as a "stabilizer", "regulator", and "power bank", achieving an annual power generation of about 1.2 billion kilowatt hours and an annual pumped electricity of about 1.6 billion kilowatt hours. This will effectively enhance the regional power grid's ability to absorb new energy such as wind power and photovoltaics, reduce the operating costs of the power system, and provide safe, reliable, and clean energy support for the coordinated development of Beijing Tianjin Hebei region.

As a leading global enterprise in the fields of energy, electricity, water resources, and environment, China Power Construction Corporation has profound technical accumulation and rich practical experience in pumped storage engineering construction. It has undertaken multiple large-scale pumped storage power station projects in China, and its technical level and engineering quality are in a leading position in the industry. The winning bid for the Xingtai project this time is a high recognition of China Power Construction's comprehensive strength by the market, and also demonstrates the company's responsibility to serve the country's "dual carbon" strategy and assist regional energy transformation.

In the future, China Power Construction Corporation will establish a professional project team, strictly adhere to the principles of "safety first, quality first, and green construction", efficiently promote the main project of the power station, installation of mechanical and electrical equipment, and construction of supporting facilities, and ensure that the project is completed and put into operation on schedule. The implementation and operation of this power station will further improve the layout of pumped storage power stations in the Beijing Tianjin Hebei region, promote energy production and consumption revolution, and lay a solid foundation for achieving regional carbon peak and carbon neutrality goals.

The construction of Xingtai pumped storage power station will complement and link with the pumped storage projects that have been put into operation and are under construction in the Beijing Tianjin Hebei region, building an "energy storage matrix" covering the core area, greatly improving the frequency regulation and peak shaving response speed of the power grid and the efficiency of new energy consumption. For Xingtai, Hebei Province, the project not only drives the development of related industries such as construction machinery and building materials, creating a large number of job opportunities, but also promotes the positive interaction between regional ecological protection and economic development through the practice of green construction concepts. Environmental protection measures such as vegetation restoration, soil and water conservation, and noise control adopted during the construction process will achieve the coordinated promotion of engineering construction and ecological protection.

At the industry level, the implementation of this project will further promote the iterative upgrading and large-scale application of pumped storage technology. China Power Construction Corporation will integrate digital and intelligent technologies into project construction, creating a benchmark for "smart power stations". The entire process from engineering design, equipment installation to operation and maintenance management will use BIM technology and intelligent monitoring systems to achieve real-time perception and precise control of power station operation status. This practice can not only provide replicable and promotable construction experience for subsequent pumped storage projects, but also help China's pumped storage industry transform from "scale growth" to "quality improvement", and enhance its core competitiveness in the global energy storage field.

With the deepening of the "dual carbon" goal, pumped storage, as the most mature and economically optimal long-term energy storage method currently available, has seen a continuous increase in market demand. The acquisition of the Xingtai project by China Power Construction Corporation is not only an important layout for the company to deeply cultivate the energy storage track, but also adds a "ballast stone" to the energy security guarantee of the Beijing Tianjin Hebei region. In the future, with the completion and operation of power stations, the Beijing Tianjin Hebei region will further reduce its dependence on fossil fuels, accelerate the transformation of energy structure towards clean and low-carbon, inject lasting green momentum into regional high-quality development, and provide vivid practical examples for the large-scale construction of pumped storage projects nationwide.Edieot/Bian Wenjun
