Transmission and distribution

Abengoa is a global benchmark in the construction of transmission and distribution infrastructures, with more than 27,000 km of transmission lines and more than 330 substations built in the last 15 years.

We carry out projects of medium, high and very high voltage and we have capacities to carry out integral projects, supply of materials, complete assembly, cable laying, OPGW and live-line working.

We build high and medium voltage electrical substations of any technology, from conventional AIS substations to GIS substations, as well as all the work related to them.

Main activities:

  • Electrical substations.
  • Transmission and distribution lines.
    • Alternating Current (AC).
    • Direct Current (DC).
    • Underground.
  • OHTL and SS engineering.
