en.Wedoany.com Reported - On April 20, the panel pouring of the upper reservoir dam of the Hubei Tuanfeng Weijiachong Pumped Storage Power Station was completed, marking the conclusion of a key phase in the main works of the station, laying the foundation for the first unit to be operational by the end of July 2026.

The station, located in Tuanfeng County, Huanggang City, Hubei Province, is a major energy project under the province's 14th Five-Year Plan. The upper reservoir dam is designed as a reinforced concrete face rockfill dam, with a maximum height of 69.5 meters and a crest axis length of 422.31 meters. The panel construction adopted a "trackless slipform" process, achieving a peak daily concrete pouring volume exceeding 300 cubic meters, setting a record for similar types of power stations. The project team introduced a digital intelligent temperature control system to optimize the mix ratio, achieving the goals of "solid interior and smooth exterior, no cracks and no leakage," and implemented safety responsibility measures to ensure construction safety.

Currently, approximately 80% of the overall project volume has been completed. The first unit is scheduled to be operational by the end of July 2026, with an upper reservoir filling test planned for May 2026. Upon completion, the station is expected to generate 330 million kilowatt-hours of electricity annually, save approximately 113,000 tons of standard coal, and reduce carbon dioxide emissions by 180,000 tons, contributing to peak shaving of the Hubei power grid and regional green development. The project team will strengthen control measures to ensure timely power generation and aim to set a benchmark for small and medium-sized pumped storage power stations.
