Study of the Route and Environmental and Social Impact Assessment (ESIA) of the 225 kV Line between Nzerekore in Guinea and Bamako in Mali

This interconnection line project is a high priority that will make it possible to have a stable electric connection between the Nzerekore (Guinea) and Bamako (Mali) stations.

This project has strategic importance for the WAPP (West African Power Pool) which aims to create a regional electricity market in West Africa by developing key infrastructure projects that favor electricity exchanges at the sub-regional level.
