German engineering firm Voith has secured a contract, worth over €100m, to supply generators and turbines for Cambambe II hydropower plant in Angola.
On completion, the plant located at River Kwanza is expected to double Angola's installed hydropower capacity.
As per the deal, Voith will supply and install four generators and turbines, as well as the control and associated systems.
The capacity of the four generator turbine units will add a total of over 700MW.
Voith Hydro president and CEO Roland Münch said: "With our supply, we are contributing sustainably to the economic development of Angola."
The new hydropower plant is being built next to the existing facility of Cambambe I, to enable it to utilise the infrastructure and dam that is already available.
Voith said that there is considerable potential for further hydropower development in Africa, which amounts to an expected 400GW, while the current installed capacity is no more than 25GW.
The hydropower potential is expected to bring 18GW to Angola, with only 4% of that having been developed so far.
Voith has recently finished modernisation work in the Cambambe I hydropower plant, which has increased output by about 40%.
In Ethiopia, the company has supplied turbines and generators to the Gilgel Gibe II plant, which has doubled the country's installed hydropower capacity and raised the share of electricity supplied to the rural population from 15% to 50%.
Earlier in March 2013, Voith won a contract to refurbish a hydropower plant owned by Rheinkraftwerk Albbruck-Dogern in Germany.
