In November 2003, the South African Government published the White Paper on Renewable Energy setting a target of 10,000 GWh renewable energy contribution to final energy consumption by 2013, to be produced mainly from biomass, wind, solar and small-scale hydro. This meant approximately 4% of the projected electricity demand for 2013.

In 2010, the Integrated Resource Plan (IRP) was released by the South African Department of Energy (DoE). According to the IRP, 42% of the total additional new capacity until 2030 was to be sourced from renewable energy sources, including 1,000 MW of CSP.

In June 2011, the DoE announced the Renewable Energy Independent Power Producer Procurement Programme (REIPP Programme), designed to start and stimulate the renewable energy industry in South Africa.

In the first window, the average bidding prices were R2.69/kWh. The Bookport project offered a bid price of R2.51/kWh.

Projects awarded in Window 3 have a new tariff system: a base price of R1.65/kWh payable for 12 hours every day and a 270% premium on the base price payable for electricity dispatched during the 5 peak demand hours.

CSP development under the REIPPP Programme:

Window 1:

KaXu Solar 1: 100 MW parabolic trough plant with up to 3 hours of molten salt energy storage system. Operational.

Khi Solar 1: 50 MW steam tower plant with a steam accumulator for 2 hours of thermal storage. Operational.

Window 2:

Bokpoort: 50 MW parabolic trough plant with 9.5 hours of thermal storage. Operational.

Window 3:

Xina Solar One: 100 MW parabolic trough plant with 5 hours of thermal storage. In development.

Ilanga CSP 1: 100 MW parabolic trough plant with 5 hours of thermal storage. In development.

Window 4:

Redstone: 100 MW parabolic trough plant with 5 hours of thermal storage. In progress.

The South African state utility ESKOM said in 2013 (and confirmed in 2016) that it also plans to develop a 100 MW dry cooled molten salt tower plant with 9 – 12 hours of TES
