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.

Vietnam - Smart Grid - Power Transmission Efficiency (Phase 1)

In 2011, the Government of Vietnam 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 through KfW contributes a loan for a 2-phase transmission efficiency project.

Phase 1 of this project covered 6 subprojects, 3 new 220 kV substations, and 3 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.

Bangladesh - Feasibility Study of the Transmission System Improvement, Western Zone

Bangladesh is facing chronic power shortage, with an estimated demand gap in the magnitude of 1900 MW and power outages in urban areas of between 5 to 10 hours a day. Taking into account the demand forecast, the current load shedding and the extreme power shortage and operational constraints, PGCB launched the "Power Transmission Improvement Programme" and approached the Government for external sector assistance.

The project covers the following technical measures:

• Construction of 132 kV double-circuit transmission lines and line in-/line outs to substations
• Stringing of a second circuit on an existing 132 kV line and installation of OPGW
• Construction of 230 kV double-circuit transmission lines and line-in/line-out to existing lines
• New construction of three 132/33 kV and one 230/132 kV substations
• Extension of a total of five 132/33 kV and one 230/132 kV substations (1 GIS substation)

Nigeria - "Transmission Lines and Associated Substation Agreement" for the 80 MW AC Nova Scotia Solar PV Project

Nova Scotia Power Development Limited (NSPDL) is developing a ground-mounted 80 MW (AC) solar PV plant. The proposed site is located some 5 km from the town of Dutse in Jigawa State. The proposed plant will be connected to the national transmission grid by means of a 132 kV double-circuit overhead line between the step-up transformer at the PV site to the 33/132 kV Dutse Substation owned and operated by the Transmission Company of Nigeria (TCN). The interconnection facility will be financed and constructed by NSPDL, but ownership will be transferred to TCN upon commissioning.

The project consists of advisory services to NSPDL for the completion and negotiation of a "Transmission Lines and Associated Substation Agreement" with TCN.
