This energy storage installation is an effective operation tool of the electrical system for improving supply guarantee, system security and renewable energy integration on the island of Gran Canaria.
The Soria-Chira pumped-storage hydropower plant will be an energy storage infrastructure that will contribute to move towards a new, more secure, efficient and environmentally friendly energy model in the Canary Islands.
Benefits of the Canary Island electrical system
The benefits it will provide the Canary Islands’ electricity system are the following:
- Increased guarantee of supply for Gran Canaria, by increasing the installed power capacity and strengthening the security of the electricity system; elements that are essential for an isolated electricity system, as is the case of the Canary Islands system, in order to reduce the vulnerability of the system as a whole. In addition, in the event of a supply interruption, this facility will help speed up and drastically shorten the service restoration times.
- An increase in the integration of renewable energies by having an essential facility to take advantage of the surplus of renewable energies and that will help integrate a greater amount of locally produced energy. In 2026, the power station will increase renewable energy production on the island by 37%, over the estimated energy that would be generated without the existence of this facility, would raise the average annual coverage of the demand using renewable generation to 51%, which at specific times may be much higher. This will lead to an additional reduction in annual CO2 emissions of 20%.
- Increased energy independence and savings in variable generation costs amounting to 122 million euros per year by reducing imports of more expensive and polluting fossil fuels.
