Spanish electric utility provider Endesa has commissioned Spain’s first grid-connected energy storage systems on three of the Canary Islands, off the western coast of Morocco.
Each of the three sites will utilise different methods of storing energy. The facility on the island of Gran Canaria will have 1MW/3MWh lithium-ion batteries that will be used as a power source, as well as for voltage regulation and demand management services.
A 500kW/18MWs flywheel system has been installed on La Gomera to provide 36 seconds of energy for frequency regulation.
On La Palma a 4MW ultracapacitor has been integrated into the existing diesel power station to give five seconds of rapid response power regulation.
The three installations aim to reduce the islands’ dependence on fossil fuels by reducing the demand on fossil fuel peak generating plants.
