The steady implementation of the dual carbon strategy and the continuous acceleration of the construction of a new power system. Pumped storage, with its outstanding advantages such as advanced technology, outstanding peak shaving efficiency, safe and reliable operation, and long service life, has become the core pillar of the energy storage field and an important guarantee for promoting the consumption of new energy and ensuring the smooth operation of the power grid.

By 2025, the pace of approval, commencement, and construction of domestic pumped storage projects in China will accelerate comprehensively. As a leading enterprise in the global energy and power field and a core force in domestic pumped storage construction, China Power Construction Corporation has accurately laid out high-quality pumped storage resources, orderly promoted project approval and large-scale construction, and delivered impressive annual development results under the trend of industry expansion.

Project approval running acceleration

With the core competitive advantage of the entire industry chain, China Power Construction Corporation accurately selects high-quality pumped storage project resources, scientifically plans the overall layout, and fully promotes the pre project research and approval process. By the end of 2025, the company has approved a total of 22 pumped storage projects with a total installed capacity of 30.9 million kilowatts, providing sufficient project reserves and laying a solid foundation for future capacity release and long-term development. In the process of project implementation and construction, the efficiency of engineering conversion continues to improve. A total of 12 pumped storage projects were approved for construction throughout the year, with a total installed capacity of 16.1 million kilowatts. From reserve planning to approval, and then to commencement of construction, China Electric Power Construction has created a virtuous cycle of reserve, approval, and construction, further consolidating its leading advantage in the pumped storage industry.

Steady performance realization

As the business scale continues to expand, the operational efficiency of the enterprise steadily improves. By 2025, the revenue of China Electric Power Construction's pumped storage sector will reach approximately 26.995 billion yuan. The excellent revenue performance fully demonstrates that pumped storage business has become the core profit growth point of the enterprise, and also demonstrates the comprehensive service strength of the company in survey and design, engineering construction, investment and operation, and post operation and maintenance one-stop full process. With the concentrated implementation of pumped storage projects nationwide, enterprises have deeply participated in the construction of key projects in various regions, firmly stabilizing their market share and continuously releasing their profit potential.

Anchoring the long-term value of energy storage

The medium and long-term development plan for pumped storage in China is being promoted in an orderly manner. Various regions have successively introduced supportive policies, increased investment and construction efforts in pumped storage projects, effectively resolved the problem of unstable and volatile new energy generation such as wind power and photovoltaics, and met diversified electricity needs such as grid peak shaving, energy storage, frequency regulation, and emergency support.
