The project involved design engineering, the supply of materials and construction of the modifications of the 66 kV lines of the OCP Jorf industrial plant.

Part of the lines are underground, and therefore galleries were designed and built including all the auxiliary facilities (fire protection, ventilation, lighting, etc.). The power cables run through these galleries, along with the rest of communication cables, control cables, etc. In addition, more than 30 km of 66 kV overhead lines with 220 kV supports were designed and constructed.
