Non-peninsular systems

The non-peninsular systems are smaller and have limited connection to the peninsula, or none at all. They serve the Balearic and Canary archipelagos, as well as the autonomous cities of Ceuta and Melilla.

Supplying energy 24x7, wherever you are

As the national TSO, our aim is to ensure the electricity supply 24x7. For the Balearic and Canary Islands, Ceuta and Melilla, where our presence guarantees the participation of different actors within the electrical sector under the same conditions as the rest of Spain, we aim for maximum efficiency and competitiveness at all times.

What makes these systems unique

The systems that guarantee the electricity supply in the Balearic and Canary Islands, Ceuta and Melilla share some unique aspects that determine how they operate. These are just some of the special features that make this process different.

Their small size and isolated geographical location.

Less stability due to the problems in connecting islands to each other and, therefore, fewer options in terms of responding if needed.

More concentrated demand with large variations in a short time.

Greater difficulty in managing renewable generation technologies.

Balearic Islands

The Balearic electrical system is unified, because all the islands in the archipelago are connected to each other and to the peninsula at the same time through the submarine link that began operating in 2012. The operation of this electrical system is managed from the Control Centre for the Balearic Islands, in Mallorca.

First Peninsula-Balearic link

A landmark because of its unique nature and technical difficulty, it means that the Balearic archipelago system is backed up by the peninsular system and can increase its use of renewables.

New Ibiza-Formentera link

A new alternating current link between the Pityusic Islands with two 132 kV circuits and a transformer capacity of 53 MVA each.

Canary Islands

The Canary Islands’ electrical system consists of six smaller systems, one for each island in the archipelago and the electrical link between the islands of Lanzarote and Fuerteventura. There is a control centre for the Canary Islands in Las Palmas de Gran Canaria which manages each of the systems in the archipelago.

Salto de Chira

Learn about our project for the pumped hydroelectric energy storage plant that we are developing in Gran Canaria, a vital tool for managing the island’s system.

Ceuta and Melilla

The autonomous cities of Ceuta and Melilla, because they are small, do not have a transmission grid, and each system is operated independently from the Balearic Islands control centre in coordination with the generators and distributors within the city.

Peninsula-Ceuta connection

We are working to improve the quality of supply for the autonomous city with a link from the peninsula that enables us to provide renewable power to the only part of our country without green energy.

This is how we see the electrical future in our country
