Guinea - Linsan - Fomi Transmission Line (CLSG / Rural Electrification Component Guinea)
The Linsan - Fomi transmission line project is one of the priority projects identified in the elec-trification masterplan of Guinea. The implementation of this line aims at ensuring a stable in-tegration 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

Vietnam - Smart Grid - Power Transmission Efficiency (Phase 1)
In 2011, the Vietnamese government approved the National Power Sector Development Masterplan VII (PDMP VII) and approved a number of power generation and transmission projects to be implemented between 2011 and 2020. German financial cooperation, via the KfW, contributes a loan for a 2-phase transmission efficiency project.
Phase 1 of this project covered six subprojects, three new 220 kV substations, and three new 220 kV transmission lines for which the Vietnam National Power Transmission Corporation (NPT) prepared feasibility studies and ESIAs.
The consultancy services contracted under this Phase 1 covered contract support to KfW in the preparation of the overall project.
