en.Wedoany.com Reported - Concrete pouring for the generator floor of the first unit at the Zhongdong Pumped Storage Power Station in Huizhou, Guangdong, was recently completed, taking nearly 24 hours. This marks the transition of Unit 1 from the structural concrete pouring phase of the powerhouse to the preparatory stage for overall unit installation and assembly.

The successful pouring of the generator floor for the first unit represents another critical milestone, following the completion of the powerhouse gallery floor, spiral case floor, turbine floor, and intermediate floor. Construction of each layer faced technical challenges such as complex structures, dense embedded components, and stringent temperature control requirements. The Huizhou Zhongdong Owner's Project Department coordinated the collaboration between civil engineering and electromechanical disciplines, optimizing the workflow sequence. The constructor activated the mixing system and backup stations in advance to ensure a continuous supply of concrete and implemented temperature control and crack prevention measures.

The Zhongdong Pumped Storage Power Station in Huizhou, Guangdong Province, is a key implementation project under China's "Medium and Long-Term Development Plan for Pumped Storage (2021-2035)." The station has a designed installed capacity of 1,200 megawatts, equipped with three 400-megawatt reversible pump-turbine units. Construction of the main project began in December 2022, with the first unit scheduled to commence operation and generate power in 2026.

Following the completion of the generator floor concrete pour, indicators for surface flatness and internal compactness all met design requirements. The Huizhou Zhongdong Owner's Project Department will proceed to the next phase, advancing the installation of electromechanical equipment and subsequent commissioning work. Once all units of the power station are operational, it will enhance the regional grid's ability to absorb fluctuating power sources like wind and solar energy, supporting the secure operation of the Greater Bay Area's power system.
