Red Eléctrica maintenance technicians were able to repair the fault that occurred late yesterday on the 66 kV Las Salinas-Gran Tarajal line and therefore restored the electricity supply in the southern part of the island of Fuerteventura. At 12:33 p.m., power was restored to the Gran Tarajal 66 kV and Matas Blancas 66 kV substations, and the 132 kV substations of Matas Blancas and Jares.
The fault occurred at a transition point from an underground cable section to an overhead section of the line, which complicated the repair work, as it was necessary to remove the faulty equipment and assemble the new one, all the repair work was carried out following strict protocols in order to ensure the safety of the maintenance personnel and to ensure the correct operation of the electricity line.
The 66 kV Las Salinas-Gran Tarajal single-circuit line is the only existing high-voltage transmission line to meet the electricity demand in the area.
Red Eléctrica is planning the construction of a 132 kV double-circuit line to increase the meshing of the transmission grid, which will provide greater security to the Lanzarote-Fuerteventura electricity system and prevent a fault of this type from affecting the electricity supply. At present, the 132 kV double-circuit sections for the Oliva-Puerto del Rosario and Gran Tarajal-Matas Blancas lines are already built and in service, with the section linking the Puerto del Rosario and Jares substations still pending to be completed.
REE again offers its apologies to users who may have been affected by this incident.
