Spanish Government Approves Electrical Infrastructure Projects in Tenerife

Overview

On June 1, 2026, the Spanish government’s official bulletin published a comprehensive resolution that authorizes a series of electrical infrastructure projects designed to reinforce and modernize Tenerife’s power grid.

The approval specifically covers:

• The construction of a new 66 kV substation in Drago
• Multiple underground and overhead power lines connecting various municipalities including Icod de los Vinos, Guía de Isora, and Los Realejos

Environmental and Technical Considerations

This extensive evaluation highlights both environmental and technical considerations, emphasizing an overall preference for underground installation to minimize visual and ecological impact.

The projects aim to:

• Address technical deficiencies in the current network,
• Ensure reliable power supply to significant portions of the island,
• Comply with strict environmental standards.

"The approval underscores the importance of balancing infrastructural development with the preservation of Tenerife’s unique natural heritage and landscape."

Challenges and Sensitive Areas

The resolution acknowledges the complexities involved in having the infrastructure pass through protected natural spaces such as:

• Reserva Natural del Chinyero
• Parque Rural de Teno

Where installation of aerial lines is largely prohibited.

As a result:

• A significant part of the authorized work involves undergrounding lines in sensitive areas,
• Employing innovative construction techniques to reduce ecological disturbances.

Conditions and Environmental Measures

Conditions included in the approval mandate:

• Detailed environmental monitoring
• Archaeological oversight
• Measures to avoid damage to local flora and fauna, notably endandered bird species and endemic plant habitats.

The approval emphasizes the importance of:

• Balancing infrastructural development with environmental preservation
• Sustainable energy infrastructure integration on the island.
