The cables through which the electricity will travel between France and Spain are already “winding” along the interconnection tunnel that links both countries. The installation was completed at the end of October and entailed a very meticulous and precise process. To unwind the cables and place them in the supports inside the tunnel, the technique of “snaking” was employed. This is a sinusoidal motion, similar to a snake, which gives the cable a sufficient curvature to easily absorb the expansion caused by the current flow.
Since 7 October, electricity has been flowing through the 400 kV power line between Bescanó and Santa Llogaia. This marks a step further towards the new electricity interconnection between France and Spain. Santa Llogaia is the location of the converter station for the interconnection implemented by INELFE, a joint venture between Red Eléctrica de España (REE) and Réseau de Transport d’Électricité (RTE). This interconnection will make it possible to double the power exchange capacity between the two countries.

After two years of work, the excavation of the trenches for the new electrical interconnection between France (Baixas) and Santa Llogaia (Spain), as well as the construction of the converter stations, was completed this summer.
