Sadc targets $4bn high-priority energy projects

Southern Africa has identified at least nine high-priority energy transmission projects valued at more than $4 billion for promotion and marketing to investors. According to information released during the 34th Summit of Sadc Heads of State and Government taking place in Victoria Falls, Zimbabwe, the nine projects are at various stages of development and include the flagship ZiZaBoNa Interconnector Project to be implemented by Zimbabwe, Zambia, Botswana and Namibia.

Other projects accorded high priority include the Central Transmission Corridor (CTC), the Mozambique Backbone Project, the Zambia-Tanzania-Kenya Inter-connector as well as the proposed Namibia-Angola Inter-connector that will connect Tanzania and Angola to the Southern African Power Pool (SAPP).

Director of Infrastructure and Services at the Sadc Secretariat Remmy Makumbe said a joint utility steering committee comprising officials from the Zimbabwe Electricity Authority (ZESA) and ESKOM of South Africa has been formed to steer the CTC project and that draft terms of reference for technical and commercial teams have been developed.

“ZESA, in conjunction with ESKOM, is studying current network configuration and capacity, and is reviewing all possible technical options available for the CTC project to increase network transfer capacity,” Makumbe said.

The Southern African Power Pool, which co-ordinates the planning, generation, transmission and marketing of electricity on behalf of utilities in the region, completed the tendering process for the ZiZaBoNa project in May 2013 and a number of investors are reported to have expressed interest in developing the electricity transmission inter-connector.

The transmission inter-connector project has the capacity to increase power trading among participating utilities, as well as providing an alternative route to de-congest the existing central transmission corridor that passes through Zimbabwe.

The ZiZaBoNa project is an example of regional co-operation and integration, and its completion would go a long way in ensuring that most SADC countries are able to share surplus energy.

Under the ZiZaBoNa agreement signed in 2008, power utilities of all four countries are expected to finance parts of the project that fall within their national boundaries, that is, Zimbabwe Electricity Supply Authority (ZESA), Zambia Electricity Supply Corporation (ZESCO), Botswana Power Corporation (BPC) and Namibia Power Company (NamPower).

The initial capacity of the transmission inter-connector will be 300 megawatts (MW), which will be increased later to 600MW. The project is to be implemented in two phases.

The first phase will cover the construction of a 120-kilometre, 330 kilovolt line from Hwange Power Station to Victoria Falls where a switching station will be built on the Zimbabwe side. The line will extend to a substation at Livingstone in Zambia.

The second phase will involve the construction of a 300km, 330kV line from Livingstone to Katima Mulilo in Namibia, through Pandamatenga in Botswana.

The Zimbabwe-Zambia inter-connector will be built as a high voltage line with a transmission capacity of 430kV.
However, it will operate as a 330kV line during the first phase. When fully operational, the ZiZaBoNa transmission inter-connector will, among other things, make it possible for NamPower to import power to Namibia directly from Hwange in Zimbabwe.

Currently electricity from the Hwange Power Station is routed to Namibia through South Africa. With respect to the CTC in Zimbabwe, the project involves construction of power lines to increase the north-south transfer capacity of the Zimbabwean network from 200kV to 600kV. This corridor is critical for SADC, as most utilities in the region use the Zimbabwe network for their power wheeling.

The project entails the development of transmission lines from Alaska to Sherwood, Bindura to Mutorashanga, and Marvel to Insukamini in Zimbabwe. —

    There is no point in investing in public utilities if the ‘off-takers’ can not or will not pay for the product. No successful business, private or public, will long remain successful if their products are used without payment. Zimbabwe does not need more electric generating or distributing capacity until a protocol to ensure they are being paid for their product is developed and successfully implemented. If one can’t pay for electricity, (or any other product) why should they have it? Once the thieves and freeloaders are eliminated they may discover they have adequate generating and distributing capacity. Of course I understand there are political ramifications involved that constitute the main problems. But paying for a product is much better than eventually having no product at all.
