GES main projects in this field are focused on the turnkey projects, specifically the construction of step-up electrical substations for wind farms and solar plants. However, GES has the required capability, experience, know-how and human and technical resources necessaries for the development and implementation of any kind of transport grid, including substations and electrical lines.

The main added value offered by GES as energy service provider is the capability to develop a whole substation construction project, starting from the engineering requirements to the complete assembly and erection. GES provides an integral construction service.

Experience and know how to commit the installation of any kind of transport grid


GES has its own engineering department dedicated exclusively to the substations and electrical lines design. This team has the experience and knowledge needed for leading and implementing such kind of projects internationally.

The engineering team is dedicated to the development of the detailed engineering of electrical substations and/ or lines.
