San Vicente Pumped Storage

Technology Type Closed-loop Pumped Hydro Storage
Rated Power 500000 kW
URL More about San Vicente Pumped Storage
The San Vicente Pumped Storage Project would establish a small reservoir above the existing San Vicente Reservoir, and a tunnel system and underground powerhouse to connect the two reservoirs. The powerhouse would contain four 125 MW reversible pump-turbines capable of lifting water to the upper reservoir or generating power as it flows down. During peak energy demand, water would flow down to generate carbon-free power. During off-peak periods, including daytime when renewable wind and solar power supplies exceed demand, water would be pumped to the upper reservoir.This would be a closed loop, off-stream system in an upland area with no natural water body. The exchange of water between the two reservoirs would not consume water or interfere with existing water supply, water quality, fisheries, or recreational uses of the San Vicente Reservoir.
