    Pumped storage facility in Salto de Chira

    Sener is developing the construction engineering of the pumped-storage facility in Salto de Chira, on the island of Gran Canaria, designed and financed by Red Eléctrica.

    This 200 MW hydroelectric storage facility (equivalent to 36% of the island’s peak demand) will connect the existing reservoirs of Chira and Soria, in the south of the island.

    The facility will act as a large natural battery, providing a storage capacity of 3.5 GWh, enough to power the island for almost 7 hours.

    Benefits

    3.5 GWh storage capacity.
    Enough to power the island for almost 7 hours.
    Energy from renewable sources.
    Stores surplus energy from wind and solar.
    Maximises the island’s energy independence.
    An innovative design conceived by Red Eléctrica.
    Reduces fossil fuel imports.

    HOW DOES IT WORK

    Stores surplus energy

    The pumped storage facility in Salto de Chira will be used to store surplus energy from renewable sources, such as wind and solar.

    Reinforces the electricity supply

    This facility will serve to reinforce the electricity supply on the island and promote the integration of renewables into the island’s electric grid.

    Construction design by Sener

    For this project, Sener is doing the construction design work of the different elements that make up the pumped storage facility:

    • The access roads to the different areas of the project.
    • The underground access tunnels.
    • The intakes at the Chira and Soria reservoirs.
    • The buildings of the different platforms.
    • The hydromechanical and electromechanical equipment and installations.
    • The control system.
