Name of the Project
San Vicente energy storage project.

Location
San Diego, California, in the US.

Client
San Diego County Water Authority and the City of San Diego.

Project Description
The project proposes meeting the future energy needs of the San Diego region through a new pumped-storage opportunity at the San Vicente reservoir site.

The proposed project will create a new, up to 500 MW source of renewable energy, which could provide grid stability for the region during peak times or when demand for electricity is high and renewable-energy supplies are low.

The San Vicente energy storage facility will establish a small reservoir above the existing San Vicente reservoir, and a tunnel system and underground powerhouse to connect the two reservoirs.

The powerhouse will contain four 125 MW reversible pump turbines to lift water to the upper reservoir or generating power as it flows down.

During peak energy demand, water will flow down to generate carbon-free power.

During off-peak periods, including daytime when renewable wind and solar power supplies exceed demand, water will be pumped to the upper reservoir.

This will be a closed loop, off-stream system in an upland area with no natural waterbody.

The exchange of water between the two reservoirs will not consume water or interfere with existing water supply, water quality, fisheries or recreational uses of the San Vicente reservoir.

Power generated at the facility will be delivered to the local grid through new transmission lines parallel to the Sunrise power link.

The new lines will connect to a substation located about 8 km away.
