With a presence in Mozambique now spanning more than 10 years,
Bouygues Energies & Services took on a complex technical project to supply electricity to the Vale mine.

The installation of the dual-circuit line required:

  • the mine-sweeping and clearing of 42 km² of savannah
  • the installation of 124 overhead pylons and their foundations
  • the installation of 600 km of cable

The project was a major technical challenge for Bouygues Energies & Services, involving deployment on land and over water. Crossing the Zambezi river required the work of design/build teams from France and Africa for the installation of:

  • Two 156-m high pylons on each bank of the river
  • 2,600m of suspended Curlew cables (with carbon fibre cores), connected to a central supporting structure

The Vale project was also a remarkable challenge in terms of manpower:

  • + 500,000 hours of work
  • cooperation between multi-cultural teams
  • training local teams to work at heights and a gradual ramp-up of their skills
  • zero accidents

Bouygues Energies & Services is proud to have contributed to the development of the region and Mozambique’s power grid infrastructure.
