Abengoa has a multidisciplinary engineering team, highly qualified and capable of adapting to any environment, specialized in the development of engineering applied to works in the transmission and infrastructure business.

Our great difference lies in the continuous feedback between work and engineering phases, as well as the adaptation of the team to different markets, clients, regulations or construction issues, which is often translated into transfer of Know-How and knowledge between projects

The main engineering activities carried out are:

  • Design of overhead and underground transmission lines.
  • Design of substations of any type (GIS or AIS).
  • Designs of railway electrification systems (catenary and traction substations).
  • Designs of civil works.
  • Design of industrial infraestructure.
  • Design of renewable generation plants: photovoltaic or wind.
  • Design of communication systems.
  • In addition, any type of design associated with previously exposed systems such as: electrical, mechanical, electromagnetic compatibility studies, short circuit studies, RAMS (Reliability, Availability, Maintainability & Safety) studies, electrical simulations, systems of protection and control, systems of communications, protection and control, energy storage systems, maintenance plans, etc.
