The Las Caletillas substation comes into operation to reinforce the electricity supply to the metropolitan area and the north of Tenerife



Red Eléctrica has commissioned the new 220 kilovolt Caletillas substation, in which it has invested 10 million euros.

This is a “very important” infrastructure for the electrical system of Tenerife, which is part of a set of measures necessary to guarantee security of supply throughout the northern zone and the metropolitan area of ​​the island, the company explained in a statement. .

The new substation has been built with shielded technology of the Gas Insulated Switchgear (GIS) type inside a building, “occupying less space and with greater reliability than a conventional substation”, highlights Red Eléctrica.

This infrastructure is part of the 220 kV Caletillas-El Rosario axis, the SE El Rosario 220/66 kV, and the 66 kV connection lines, which will be put into voltage in a second phase, to reinforce the supply to the metropolitan area and the north of Tenerife, and increase the security and quality of supply.

The new Caletillas substation reduces the dependence of the power supply in the north of Tenerife on the Candelaria substation, “improving the security of supply of a significant volume of electricity demand on the island”, Red Eléctrica emphasizes.

“Many” of the lines that are connected today at the Candelaria substation will do so progressively at the new Caletillas substation “reducing vulnerability, increasing security of supply and additionally reducing the visual impact of infrastructures.”

The new Caletillas substation has been designed in collaboration with the Escuela Superior de Arquitectura de Las Palmas de Gran Canaria with a vertical plant façade based on local flora, and complies with the conditions established in the Environmental Impact Statement of the project.

The entry into operation of the new Caletillas substation, which is located next to the Candelaria thermal power plant, coincides with the maintenance work on the transmission network at the Granadilla 220 kV substation and at the access to the Granadilla-Candelaria line DC 220kV.

These actions will be carried out during the holidays and weekends between this Sunday, April 23 and May 14, in order to preserve the guarantee and quality of the electricity supply.

The works will be carried out on the days of lower energy demand to minimize disturbances to users.
