The interconnector increases the power-exchange capacity between Portugal and Spain by around 1,000 MW, making the Iberian electricity system more robust and efficient, and promoting the green transition on both sides of the border.
On the Portuguese side, the investment was channelled into the construction of the new 68 km power line and the Ponte de Lima substation, which has been in operation since 5 December. On the Spanish side, the interconnector led to the development of the Beariz substation, the Beariz–Fontefría power line, the Fontefría substation and the Fontefría–Frontera power line.
