On March 3, 2026, Wudongde Reservoir officially launched an ecological scheduling trial for "base-load power generation", marking the beginning of this year's ecological scheduling trials for the world's largest clean energy corridor to promote the reproduction of demersal adhesive egg-laying fish.

This trial centers on the reproductive habits of demersal adhesive egg-laying fish. During their reproduction, the fish lay eggs that attach to aquatic plants or rocks. Therefore, a stable downstream dam water level is a prerequisite for ensuring the hatching of these eggs. With strong support from the Changjiang Water Resources Commission and China Southern Power Grid, CYPC (a subsidiary of CTG) proactively planned and coordinated with multiple parties. By optimizing the cascade reservoir operation plan to align with the fish's reproductive cycle, CYPC secured the experimental window and managed the daily average outflow from the Wudongde Reservoir. This ensured a stable water level fluctuation at the Wudongde Hydrological Station downstream, creating stable flow conditions in the river channel downstream of the dam and providing a suitable environment for the fish reproduction.

It is reported that the ecological scheduling trials for the world's largest clean energy corridor mainly include types such as "selective water withdrawal with stop log gates", "base-load power generation", and "artificial flood peaks". These trials provide a solid guarantee for restoring aquatic biodiversity by controlling water temperature and discharge. This ecological scheduling trial for "base-load power generation" was conducted at both the Wudongde and Baihetan reservoirs and was expected to be completed in mid-to-late March.

Looking ahead, CYPC will further enhance hydro-meteorological monitoring and forecasting, continuously rolling out optimized cascade reservoir drawdown processes. Balancing multiple needs, including navigation and water supply, the Company will dynamically adjust the operation of the cascade reservoirs and meticulously carry out ecological scheduling trials, making greater contributions to the green development and ecological conservation of the Yangtze River Economic Belt.
