Eiffage Energía’s most important substations

Eiffage energy stands out as a benchmark company in the construction of substations in Spain and internationally. Eiffage Energía currently has more than 50 implemented substations and 2,400 MVAs in different voltages and types from 45 KV to 400 KV.

In this line of business, the company offers different services with the professionalism and commitment with which each project is implemented. Among the services offered the following are included: turnkey projects, basic and detailed engineering, development of control and protection projects, electromechanical assembly, maintenance and operation of substations, among many others.

The professionalism with which each substations project is implemented is done integrally including engineering, procurement, construction, operation and maintenance. A distinguishing feature of Eiffage Energía’s process of implementation for each of its customers.

Below, we list the most important substations that the company has built so far, which are those of Huatacondo, the mega-project of Eiffage Energía in Chile.
