Under the karst mountains of Guizhou, there are countless caves and fissures hidden, like a huge geological maze. In the past, building large-scale water conservancy projects here was fraught with risks and difficult to achieve. Nowadays, advanced technologies such as geological radar and CT imaging are like "perspective eyes", accurately outlining the veins of the underground world and clearing obstacles for the landing of national energy strategic projects - pumped storage power stations. This is a microcosm of China Electric Power Construction, the leader in clean energy construction, driving the development of pumped storage industry in all aspects with technological innovation as the engine. Recently, from winning a large order of 6.6 billion yuan from State Grid Corporation of China, to actively increasing investment of over 10 billion yuan, and to tackling complex geological construction problems, China Power Construction Corporation is taking a series of heavyweight actions to consolidate its leading position in the industry and lay a solid foundation for building a new type of power system.

6.6 billion orders from State Grid demonstrate industrial chain advantages

The list of bidding candidates announced by State Grid has become a market focus. In the bidding for its pumped storage power station project with a total amount of over 6.6 billion yuan, China Power Construction became the biggest winner, occupying an absolute share in the core hydropower construction sector.

This bidding focuses on key pumped storage projects in multiple countries' "14th Five Year Plan" energy plans, including Chongqing Liziwan, Hunan Shuangpai Tianzishan, Zhejiang Kecheng, etc., all of which are "stabilizer" projects related to regional power grid stability and new energy consumption. Multiple engineering bureaus under China Power Construction Corporation have worked together to win five core construction sections, covering key links in the entire chain from reservoirs, upper and lower storage areas to water transmission and power generation systems.

Specifically, the Chongqing Liziwan project has an installed capacity of 1.4 million kilowatts and a total investment of 10.3 billion yuan for the construction of the reservoir, which was awarded 925 million yuan by the Ninth Hydropower Bureau; The section of the water transmission and power generation system with an installed capacity of 1.4 million kilowatts for the Hunan Shuangpai Tianzishan project was won by the 14th Hydropower Bureau for 907 million yuan; The installed capacity of 1.2 million kilowatts in the Kecheng project in Zhejiang province is composed of the 10th, 15th, and 5th hydropower bureaus, which respectively undertake the construction of the upper reservoir, lower reservoir, and water transmission and power generation system, with a total amount of over 1.9 billion yuan. This series of winning bids not only brought considerable orders, but also showcased China Power Construction's impeccable comprehensive strength and overall planning ability in the entire industry chain.

12.1 billion yuan deep cultivation in Southwest China, locking in long-term development

In addition to conquering the bidding market, China Power Construction also focuses on the long-term and actively increases strategic investments. At the end of October 2025, the board of directors of the company officially approved the investment and construction of the Luxi Pumped Storage Power Station project in Yunnan Province by its subsidiary Kunming Survey and Design Institute Co., Ltd.

The total investment estimate for this project is as high as 12.167 billion yuan, with a capital of approximately 2.433 billion yuan. This is not just a simple project contracting, but a strategic decision made by China Power Construction as the main investor, deeply involved in the full lifecycle management of the project. Investing in the Luxi project is a crucial step for China Power Construction to deepen its "investment construction operation" integration model and consolidate its core business advantages in the field of pumped storage. It will effectively improve the company's clean energy strategic layout in the southwest region, not only contributing to future operational revenue, but also enhancing regional market competitiveness to new heights, and reserve core assets for the company to meet larger scale development opportunities during the 15th Five Year Plan period.

Innovatively tackling world-class geological challenges

If winning the bid and investing reflect the "hard power" of China Power Construction, then breakthroughs at the forefront of technology demonstrate its irreplaceable "soft power". Faced with the global challenge of complex geological conditions that constrain the site selection and construction of pumped storage projects, China Electric Power Construction Corporation has delivered an impressive answer.

Taking the survey and design of the Fuquanping Pumped Storage Power Station in Guizhou Province as an example, the China Electric Power Construction Guiyang Institute, which is responsible for the task, is facing a typical all karst area with developed underground karst cave systems, and anti-seepage treatment is a world-class challenge. The project team comprehensively utilized high-tech methods such as geological radar, TSP (Tunnel Seismic Wave Prediction), CT imaging, etc., to carry out millimeter level refined geological exploration, accurately identify underground caves and fracture networks, and construct high-precision 3D geological models.

Based on this solid data foundation, the design team boldly innovated and successfully completed the design of the first vertical anti-seepage reservoir in the entire karst area in China. This breakthrough technology solution effectively overcomes the key technical bottleneck of constructing pumped storage power stations in strong karst areas. It not only paves the way for the safe and economic construction of Pingshang Power Station, but also provides a valuable "China Electric Power Construction Plan" and reliable technical reference for the construction of pumped storage projects under similar extreme geological conditions at home and abroad.
