First renewable energy in Africa found outside Upington in the Northern Cape
It was on 27 December 2016 when Abengoa received a Provisional Acceptance Certificate officially handing the plant to its owner Khi Solar One.
It is a solar thermal power-producing 50 megawatts of electricity; it is the first solar Tower plant in Africa and it is the first to achieve 24 hours of operation with solar energy only.
In fact, there are about 28 power towers, 1 in South Africa, 1 in Turkey, 5 in the USA, 3 in Spain, 1 in India, 1 in Germany, 1 in United Arab, 1 in Israel, 1 in Morocco, 1 in Chile, 2 in Spain, 1 in Australia and 9 in China.
They are known to concentrate solar power to make it a more powerful energy source, they are sometimes also called heliostat power plants because they use a collection of movable mirrors (heliostats) laid out in the field to gather and focus the sun at the tower.
As the sun shines down the solar tower’s field of heliostats, each of those computer-controlled mirrors tracks the sun’s position on two axes.
The heliostats are set up that over the course of the day, they efficiently focus that light toward a receiver at top of the tower.
The Khi Solar One is made of more than a thousand heliostats, totaling up to 576,800m2 of mirror surface placed o area of 140 hectares, the project was developed by Abengoa from Spain and financed by Industrial Development Corporation and community group, Khi community trust.
