Summary: In order to reduce the energy consumption of the Eastern route of China's South-to-North Water Transfer Project, an optimized operational model was established to schedule the water-pumping process along the transfer route. The results show that the proposed operational rules can effectively reduce the water pumping and energy consumption of the project. Additionally, raising the water levels of southern lakes at the beginning of the year can further reduce the subsequent water pumping from the Yangtze River and the relative energy use of the project. Key areas for energy-saving along the eastern route were identified, providing new insights into the water-energy nexus behaviors of long-distance water transfer projects.
