Eiffage Energía Sistemas is characterized by being a leading company in the construction of substations in Spain and internationally.

Professionalism in the execution of the work and commitment to the execution deadlines are the values that define us.

In this line of activity, the company offers different services, from the professionalism and commitment with which each project is executed.


The professionalism with which each substation project is carried out is done comprehensively, including: engineering, supply, construction, operation and maintenance. A differentiating point in the execution process of Eiffage Energía Sistemas with each of its clients.

An example is the construction of the Valdesolar photovoltaic plant substation, developed by REPSOL in Valdecaballeros (Badajoz). A project that has been a technical challenge, since it is not a standard solution in substations. It can be said that it is a solution “tailored” to what the client demanded.

Professionalism in work performance and commitment to deadlines are the values that define us."
