The majority of the projects carried out by Red Eléctrica are bound by law to this procedure. The environmental impact assessment is therefore the most appropriate tool to minimize the environmental impacts generated by Red Eléctrica’s electricity infrastructure. With it, adequate prevention of environmental and social impacts that may be causes be the facilities is ensured, whilst establishing effective mechanisms to prevent, reduce or offset these possible impacts. It also acts as a tool for communication with public administrations and other stakeholders, whose participation is essential.
Depending on the type of infrastructure that is being assessed, the following is a breakdown of which administrative body is responsible for its processing:
The authorisations that are required to carry out infrastructure projects are the following: environmental impact statement (in the majority of the cases), prior administrative authorisation, declaration of public utility, administrative authorization for construction and the operating license.
Below you will find information regarding the status of the administrative permitting process of the different projects that Red Eléctrica is carrying out, although it should be noted that this website is not the appropriate channel if you wish to present any official claim, argument or procedure.
