Tenerife Approves Vital Power Line Project After 16-Year Delay
The Canary Islands government has approved the completion of a vital power line between Guía de Isora and Adeje, ending a 16-year administrative delay to strengthen Tenerife’s electrical grid and support the island's energy integration with La Gomera.
The Canary Islands government has officially approved the completion of a new power line connecting the Chío substation in Guía de Isora to the Los Olivos substation in Adeje. This decision marks the end of a 16-year administrative process, giving the power company, Red Eléctrica, two years to finish and launch the project.
This project is a vital part of strengthening the 66-kilovolt power ring in western Tenerife. Because the island’s electrical grid is isolated and fragile, this connection is essential to prevent frequent system overloads. It will also serve as a strategic backup if the main power line between Granadilla and Caletillas-Candelaria—a critical point for the island's energy stability—should fail.
The project was finally unblocked after the route for the final kilometer was redesigned. Following feedback from local landowners during the public consultation, the power company adjusted the path to run primarily through municipal land. The Adeje City Council approved this change in February, confirming it aligns with local urban planning.
In addition to stabilizing Tenerife’s power supply, this infrastructure is crucial for the new 145-million-euro submarine cable connecting Tenerife and La Gomera. By completing this line, the regional government aims to ensure the two islands' power grids are fully integrated, significantly improving the reliability of the energy system across the Canary Islands.
