The facilities of Red Eléctrica are distributed nationwide.

One of the main criteria when defining the location of new facilities is to avoid those areas rich in biodiversity, although, in some cases, it is inevitable that installations cross or need to be located in protected spaces or in areas with species of interest (approximately 25% of the Spanish territory is protected).

In these cases, Red Eléctrica puts into motion all the necessary preventive and corrective measures to minimise the possible effects on flora and fauna, and provides additional environmental improvement actions to improve the biodiversity of the areas in which their facilities are located.

Only 0.08 % of the total surface area of Natura 2000 / Red Natura is occupied by Red Eléctrica facilities.
