9 October 2009 – Zizabona, a $225-million transmission project, which would develop new transmission lines to link four countries (Zimbabwe, Zambia, Botswana and Namibia) gained momentum as Nampower issues a request for proposals from consultants to undertake an Environmental Impact Assessment (EIA) study for this project.

The Zimbabwe Electricity Supply Authority, the Zambia Electricity Supply Corporation, Namibian Power Corporation and the Botswana Power Company, had earlier this year, committed themselves to the $225-million project, which would develop new transmission lines to link the four countries.

Zizabona, which was expected to be completed in two phases between 2010 and 2013, would ease congestion on the transmission corridor to South Africa, as well as make it easier for the four countries to trade power with each other.

The first phase of the project would involve the construction and development of transmission infrastructure in Zimbabwe and Zambia.

About 91 km of 330-kV line between the Hwange substation, in Zimbabwe, and a proposed switching station near the Victoria Falls town, in Zimbabwe, would be constructed.

A further 14-km 330-kV line would then be constructed from the switching station to the Zimbabwe/Zambia border.

Simultaneously, the Zambian authorities would undertake the construction of a 14 km 330-kV line from a proposed Livingstone switching station to the Zimbabwe/Zambia border, as well as reroute the existing Muzuma Victoria Falls power station 220 kV line into and out of the proposed Livingstone substation.

The second phase of the project would involve the construction of more transmission lines between Zimbabwe, Botswana and Namibia, as well as the construction and extension of substations in these three countries.

NamPower noted on its website that the proposed transmission line, for which it required the EIA study, would be constructed from the Ngoma border, with Botswana, to the Zambesi transmission station.

This would involve the construction of about 86 km of 330-kV line between the border and the transmission station.

Interested parties had until October 23 to submit their proposals for the EIA study to NamPower. A pre-tender meeting would also be held at the utility’s offices today.
