Which pumping station in the world generates electricity naturally without loss?

Yalong River Estuary Hybrid Pumped Storage Project. Hybrid pumped storage power station is a hydropower station with both pumped storage and runoff power generation functions. The natural runoff of the upper reservoir of the power station is fully replenished, which can not only undertake tasks such as conventional power generation and comprehensive utilization of water energy, but also increase tasks such as peak shaving and valley filling and emergency standby, such as the Yalong River Estuary Hybrid Pumped Storage Project, a hydropower station with both pumped storage and runoff power generation functions, which can undertake tasks such as conventional power generation and comprehensive utilization of water energy. It can also play the role of peak shaving and valley filling, emergency standby and so on. The reservoir has little inundation loss, no need for resettlement, little environmental impact, short construction period, and good economy and market competitiveness.
