Guinea - Linsan - Fomi Transmission Line (CLSG / Rural Electrification Component Guinea) 1,214,110 Euro (1,303,590 US$) Financing: African Development Bank (AfDB)

The Linsan - Fomi transmission line project is one of the priority projects identified in the electrification masterplan of Guinea. The implementation of this line aims at ensuring a stable integration of the national electricity networks of the ECOWAS member countries. At the same time, it serves to evacuate the power produced by the Kaleta Power Plant, the projected Souapiti HPP and other power plants to come.

The project covers the construction of approx. 394 km of 225 kV double-circuit transmission line between Linsan, Dabola, Kouroussa and Fomi with four associated 225 kV substations. It covers the following tasks:

• Line routing and production of maps, plans and profile drawings,
• Environmental and Social Impact Assessment (ESIA),
• Elaboration of the Environmental and Social Management Plan (ESMP),
• Elaboration of the Resettlement Action Plan (RAP),
• Feasibility study for the line,
• Preparation of functional prequalification and tender documents,
• Training.
