In 2026, as the opening year of the 15th Five-Year Plan, the construction of pumped storage power stations in China continues to accelerate. In the first quarter, multiple million-kilowatt pumped storage projects across the country completed the bidding for main civil engineering works one after another, and a number of key sections announced their winning bids, pushing project construction into an accelerated implementation stage. Relying on technological expertise and engineering experience, several engineering bureaus under PowerChina secured the core sections, becoming the main force in the pumped storage construction market in the first quarter.

On March 20, 2026, Xinyuan (Mengyin) Pumped Storage Co., Ltd. completed its business registration, marking the official launch of the Mengyin Huapiling Pumped Storage Power Station. Installed Capacity: 1.2 million kW (4 units) Total Investment: 8.244 billion yuan Planned Positioning: Key project in Shandong Province’s "14th Five-Year" medium- to long-term pumped storage plan, key national project for implementation in the "14th Five-Year Plan" Construction Location: Duozhuang Town, Mengyin County, Linyi City, Shandong Province Project Legal Entity: Xinyuan (Mengyin) Pumped Storage Co., Ltd. (jointly held by State Grid Shandong Electric Power Company, State Grid Xinyuan Holdings, China Resources Power, etc.) Expected Completion: 2031

Recently, a major project under the national mid- to long-term plan for pumped storage—Guangdong Dianbai Pumped Storage Power Station—has reached an important milestone. The excavation of the core underground powerhouse has been fully completed, marking the official transition of the power station construction from the civil engineering phase to the electromechanical installation phase. As a core supporting component ensuring ventilation in the underground space of the power station, our company's underground axial flow fan equipment has participated in the project's challenging ventilation works. With excellent product performance and stable operation, it has successfully completed various ventilation tasks, earning high recognition from the project stakeholders.

With the large-scale advancement of mining, tunnel construction, underground utility corridors, and other projects, as well as the continuous upgrading of safety production standards, the underground ventilation axial fan industry will usher in a new transformation in 2026. The industry as a whole is accelerating development in four major directions: intelligent control, high efficiency and energy saving, explosion-proof and corrosion-resistant, and low-noise durability. Currently, the demand for fans in underground ventilation scenarios is no longer limited to basic air supply, but places greater emphasis on full-process safety management: intelligent fans can achieve automatic air volume adjustment, remote monitoring, and fault warning, adapting to ventilation needs at different operational stages; energy-saving motors and optimized aerodynamic designs significantly reduce ventilation energy consumption; special protective designs such as explosion-proof, corrosion-proof, and moisture-proof fully adapt to the complex and harsh underground working conditions, eliminating safety hazards. At the same time, industry supervision is becoming increasingly strict, compelling enterprises to improve product quality and compliance. Our company will keep up with industry trends, continuously develop high-end axial fans suitable for underground scenarios, and contribute to the safe, green, and efficient development of the industry.
