The utilities of the four-nation Organisation for the Development of the Gambia River (L’Organisation pour la mise en Valeur du Fleuve Gambie, OMVG) have signed a transmission service agreement for the 1,677km ‘Loop’ high-voltage power transmission line.
The $685m development comprises 4,000 pylons and 15 substations and interconnects the grids of Gambia, Guinea, Guinea-Bissau, Senegal. As its name suggests, the 225kV, double-circuit line forms a circular network spanning the four countries.
