Khi Solar One is a 50 MW concentrated solar power plant with a power tower.

The power tower system uses large, sun-tracking mirrors (heliostats) to focus sunlight on a receiver at the top of a tower. Water is pumped up to the tower mounted receiver and is converted to steam, which, in turn, is used in a conventional turbine generator to produce electricity. Of the 36 operational CSP power stations worldwide, five are power towers. The power station will include a facility to store steam, enabling it to generate electricity for two hours when the sun is not shining.

Khi Solar One will use dry cooling, which dramatically reduces water consumption by two thirds. The tower plant will be located on a 600 ha site close to Upington, in the Northern Cape Province.
