The CLSG Interconnection is an operating 225 kV electricity network linking Côte d’Ivoire, Liberia, Sierra Leone and Guinea. It comprises approximately 1,300–1,350 km of high-voltage line and associated substations, enabling commercial electricity trade through the West African Power Pool. The infrastructure is completed and in operation.
The 225 kV Côte d'Ivoire - Liberia - Sierra Leone - Guinea Interconnection Project (CLSG) is a major regional power transmission infrastructure project. It involves the construction of approximately 1,303 km of 225 kV double-circuit transmission line, connecting the national grids of Côte d'Ivoire, Liberia, Sierra Leone, and Guinea. Key components include 10 new substations (4 in Liberia, 5 in Sierra Leone, 1 in Guinea), the extension of the existing Man substation in Côte d'Ivoire, installation of Static Var Compensators (SVCs) at five locations, and the establishment of a Regional SCADA system and control centers. The project is a flagship of the West African Power Pool (WAPP) and is designed to facilitate electricity trade, improve grid stability, and provide electricity access to communities along the corridor using the Shield Wire Scheme.
1. Physically interconnect the national power systems of Côte d'Ivoire, Liberia, Sierra Leone, and Guinea to the existing West African Power Pool network. 2. Facilitate regional power exchanges and trade to enhance security of supply and reduce electricity costs. 3. Improve the socio-economic conditions of approximately 169 villages along the transmission line route by providing them with electricity access. 4. Strengthen the institutional and operational framework for regional power system management within the WAPP.
