Bouygues E&S EnerTrans Ltd. plans, constructs and operates substations and tranformation stations for the high- and medium-voltage sector. We have been producing reliable, cost-effective and flexible solutions for over 80 years.

Transformation stations and substations are the hubs of the network, and planning and constructing them requires high levels of design and practical skill. Interdisciplinary thinking and action are therefore key to us. This means we can optimise the design and coordination of high-voltage technology with civil engineering and power line and safety engineering.
