Southern African Power Pool

<p>Construction of a transmission line that connects Cahora Bassa Hydroelectric Power Station at Songo in Mozambique with the power system of Zambia at Serenje.</p>

<p>The governments of the Democratic Republic of Congo (DRC) and the Republic of Zambia signed an Intergovernmental Memorandum of Understanding (IGMOU) on 9 July 2015 for the joint development of generation projects in the Luapula River Basin and for a new power interconnector between the two countries. The national power utilities of the two countries entered into specific memoranda of understandings for the development of the generation projects and for the power interconnector respectively. The Inter Utility Memorandum of Understanding for the power interconnector was also signed on 9 July 2015.</p><p>The Luapula River was initially investigated for hydropower development by the Zambian Government in 1976 during which time five sites indicated below were established and investigated. Later in 2001, ZESCO LTD confirmed the potential of over 1188MW of which more than 773MW is firm capacity. However, previous project development plans were constrained because the development plans were only coordinated from one country despite the location of the river being on the border.</p><p>The project serves a planned infrastructure asset of another sector, but there is more than 50% overlap in the geography serviced by the proposed project and the other sector planned asset.<br></p>

The Kobong Project will consist of a 1200 mW pump storage dam and power generation facility constructed along the upper Kobong River, a tributary of the Maliba-mats"’o River which flows into the Katse Dam reservoir. The majority of the power generated at Kobong will be exported to South Africa, while 20 megawatts will be used locally in Lesotho.

<p>This project involves the construction of a 11050 MW Inga 3 hydropower project on the Congo River. The project is seen as the leading clean, affordable and development option to address the challenges of energy access in Africa. It reaches beyond energy access as it would also create local employment and income opportunities and would help stabilise the political conditions in the African countries involved through cross-border cooperation in Africa and beyond.</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>The project is code named "ANNA" meaning the interconnection between Angola and Namibia. The proposed interconnector involves the construction of power transmission routed via the proposed Baynes Hydropower Plant in Lower Kunene, Namibia, to link the Namibian and Angolan electricity networks in the north western part of Namiiba and the southern part of Angola. </p>

<p>The proposed interconnector involves the construction of power transmission lines from the proposed Baynes Hydropower Plant in Lower Kunene, Namibia, to link to the national power grid of Angola. While this leg of the&Acirc; project focuses on the section in Angola, it forms part of the broader project which is in Namibia.</p>
