Gambia / Guinea / Guinea-Bissau / Senegal (four-country regional project) · RegionalEnergy — power transmission · Regional electricity transmission interconnection
The 1,677 km, 225 kV OMVG ring links the grids of The Gambia, Guinea, Guinea-Bissau and Senegal with 800 MW of trade capacity, benefiting 15 million people; USD 311m is sought toward the c. USD 711m programme.
Justification
The 1,677 km ring carries Guinea's Kaleta and Souapiti hydropower to four member states, with 800 MW of trade capacity, eight times The Gambia's peak load.¹ ² It is largely energised and brings cleaner, lower-cost power to more than 2.5 million households and businesses.²

Opportunité d'investissement
Structure de l'opération
USD 311m sought toward the c. USD 711m interconnection programme of four member states.
Utilisation des fonds
Being confirmed with OMVG; the programme covers 1,677 km of 225 kV line, 15 substations, two dispatch centres and fibre.
Source des revenus
Bilateral electricity trading contracts between the four national utilities, negotiated in 2019, with a 35-year tenor.
Ce qui est recherché
USD 311m from investors and lenders; scope, use of funds and structure are released to qualified investors under NDA.
Pourquoi le projet est bancable
The ring is largely energised; the last major substation, Antula in Guinea-Bissau, was inaugurated on 25 April 2025.³
Bilateral trading contracts between the four state-owned utilities underpin use of the line, on a 35-year tenor.¹
Built to carry power from Guinea's Kaleta (240 MW) and Souapiti (450 MW) hydropower plants to all four member states.¹
USD 200m from the World Bank and over USD 500m from co-financiers: five multilateral banks and three bilateral agencies.²

Principaux risques et mesures d'atténuation
Four utilities share the asset; trading contracts are signed and OMVG, the four-government basin body, owns it.
Revenue rests on four state-owned utilities rather than one buyer, under 35-year trading contracts.
The ring is largely energised; the last major substation was inaugurated in April 2025.³
