The Kalkaar Molten Salt Thermal Energy Storage System is a 150,000kW energy storage project located in Jacobsdal, Letsemeng, Free State, South Africa. The rated storage capacity of the project is 1,800,000kWh.
The thermal energy storage project uses molten salt as its storage technology. The project was announced in 2016 and will be commissioned in 2021.
The Kalkaar Molten Salt Thermal Energy Storage System is being developed by Engie and SolarReserve. The project is owned by Engie (50%) and SolarReserve (50%).
The key applications of the project are renewables capacity firming and renewables energy time shift.
Engie and SolarReserve are the owners. Engie and SolarReserve are the developers.
Kalkaar project will deliver about 690 GWhs of power annually – providing fully dispatchable baseload electricity to the network when electricity is needed most. Storage will enable the solar thermal station to operate just like a conventional coal, gas or nuclear power station, reliably generating electricity day and night – except without any emissions. The Kalkaar project was developed in response to the South Africa Department of Energy’s Expedited Round (referred to as Round 4.5) call for CSP projects for the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP).
