Floods in Mozambique lead to losses of US$21 million for Cahora Bassa hydroelectric dam

2 April 2013

The Cahora Bassa Hydroelectric Dam (HCB) registered losses of US$21 million due to a stoppage in sending power to South Africa after one of the towers holding up the transmission line fell, Mozambican newspaper Notícias reported.

After the tower holding up line 1 fell down, transmission of power to South Africa, since January has been at 65 percent of the usual total, using line 2, which was not affected by this year’s floods.

Moisés Machava, HCB’s director for Engineering and Maintenance, said that the 35 percent drop in supply of electricity to South African power company Eskom represented a daily loss of around US$300,000.

In order to get supply back to full capacity repairs to the fallen tower have been delayed, adjacent towers have been reinforced and a new lighter cable has been put in place, which can span a great distance without support.

According to Machava, the link to South Africa via line 1 is expected to be operational this week.

HCB is also preparing a project to better protect its transmission infrastructure, which is in line with the government’s suggestion of building dams, including along the Limpopo River. (macauhub)
