Overhead Lines

Bouygues E&S EnerTrans Ltd. plans, constructs and operates power lines for the high- and medium-voltage sector. We manage the entire approval process and take responsibility for the construction.


The configuration, construction and operation of overhead lines or power lines require not only technical expertise in various disciplines but also comprehensive process know-how. At the same time, sensitive handling of the population, authorities, associations and local interest groups is also required. We have the necessary experience to implement projects in the shortest possible time frames.
