<p>Construction of a dam and hydroelectric plant of 90 MW on the Niandan River in Guinea with a reservoir of about 5 billion m3 of water.</p>

<p>The project has two components, namely:<br />
- Strengthen the institutional and financial capacity of the Niger Basin Authority (NBA) to sustainably fulfill its basic mandate; and<br />
- Facilitate evidence-based decision-making in the process of preparing Fomi&#39;s multipurpose dams and in parallel strengthening of ABN&#39;s capabilities through its direct involvement in this complex project.</p>

<p>The Fomi Dam initiative has been continued in two related projects:<br />
First, an APL-1 project on water resources development and sustainable ecosystem management (WRD SEM) funded by the World Bank (P093806) and secondly, the Niger River Basin Management Project. It is unclear if the APL-1 project is still active through a follow-up phase which might likely be named APL-2.<br />
The Niger River Basin Management Project was approved for CIWA funding in November 2014 and aims to strengthen the NBA&#39;s capacity to prepare for Fomi in two phases, namely:<br />
a) facilitate dialogue between stakeholders in Guinea, Mali and the NBA to develop a roadmap on how to proceed with the preparation of the Fomi dam project; and<br />
b) Complementary studies to the main preparatory studies supported by WRD SEM (APL-1).</p>

<p>Burkina Faso is already connected to all its neighbors, with the exception of Benin, which is already present in Porga (Border with Burkina). Thus, the realization of this link is fully integrated into PIDA PAP 2020 and the ECOWAS Regional Connectivity Integration Strategy, which has made the development of broadband infrastructure among Member States a priority. This link will be integrated into the network currently being deployed as part the National Backbone Telecommunications Project (PBNT), of which Fada N&#39;Gourma is a main node of the national and international transmission network.</p>

<p>The section goes from Fada N&#39;Grouma to  Benin border at Porga where the physical interconnection of the optical cables will be realized with Benin Telecoms.<br />
The passive infrastructure includes two HDPE tubes, one of which will contain a 36-core G.652D cable. The length of the network is 160 km. The transmission network is IP-MPLS over OTN over DWDM with a transport capacity at the installation of 100 G. One point of presence will be created halfway to Pama.</p>

<p>The proposed BGHES is a bi-national hydro power project to be located approximately fifty-four (54) kilometres downstream of the Victoria Falls and will extend across the international boundary between the Republics of Zambia and Zimbabwe.</p>
<p>Through several subsequent studies and analysis (1981,1992-1993, 1998 and 2015) the current technical configuration for the BGHES comprises:</p>
<ul>
<li>176m high, 720m crest length Roller Compacted Concrete gravity arch dam;</li>
<li>Radial gated central crest spillway;</li>
<li>Two surface power plants, one on either side of the river bank, each with a capacity of 1,200MW, giving a combined capacity of 2,400MW;</li>
<li>6 x 200MW Francis turbines in each powerhouse;</li>
<li>Four water intakes delivering water through 4 tunnels (each approximately 1km in length) to the two surface power plants downstream of the dam;</li>
<li>Diversion tunnel</li>
<li>Switchyards for both power plants</li>
<li>Construction of the staff townships with social amenities and office complex for the Authority and Power utilities on Batoka North and Batoka South.</li>
<li>The staff townships will initially be permanent construction camps and located one on the north bank of the dam (in Zambia) and the other one on the south bank (in Zimbabwe).</li>
</ul>
<p>Single trasmission lines in Zambia (directed from the Project)&Acirc; will be located as follows:</p>
<ul>
<li>2 x 55km of 330kV, Single Circuit Overhead Transmission lines between Batoka North Bank Power Station and Mukuni Substation, Livingstone.</li>
<li>1 x 170km of 330kV, Single Circuit Overhead Transmission Line between Batoka North Bank Power Station and Muzuma Substation, Choma.</li>
<li>2 x 230km of 330kV, Single Circuit Overhead Transmission Lines between Batoka North Bank Power Station and Nambala Substation, Mumbwa.</li>
</ul>
<p>Single trasmission lines in Zimbabwe (directed from the project)&Acirc; will be located as follows:</p>
<ul>
<li>Batoka North and Batoka South Interconnector (2 x 400kV);</li>
<li>BGHES to Victoria Falls (1x 400kV x 30km) in Zimbabwe&Acirc; complete with 2 x 400kV line bays;</li>
<li>Victoria Fall to Hwange (1 x 400kV x 55km) line complete with 2 x 400kV line bays</li>
<li>Victoria Falls 400/(132)88kV Substation complete with 4 x outgoing (132)88kV line bays</li>
<li>BGHES to Chakari (2 x 400/330kV x 400km) in Zimbabwe complete with 4 x 400kV line bays.</li>
<li>Chakari to Selous (1 x 330kV x 70km) line in Zimbabwe complete with 2 x 330kV line bays The line will be 400kV construction but operating at 330kV.&Acirc; </li>
<li>Selous to Dema (1 x 330kV x 95km) line in Zimbabwe complete with 2 x 330kV line bays. The line will be 400kV construction but operating at 330kV.&Acirc; </li>
<li>All lines shall come with 2 x Earthwire peaks ( 1 x 48 Core OPGW and 1 x GSW)</li>
</ul>

<p>Upgrading of 53 km of road to dual carriageway from Bachuma Gate to Maji ya Chumvi (Kenya).</p>

This project forms part of the  priority projects  identified in the ECOWAS Master Plan for the Generation and Transmission of Electrical Energy and shall interconnect  Sierra Leone, Liberia and Guinea to the nine already interconnected countries.
