The Rooipunt Molten Salt Thermal Energy Storage System is a 150,000kW energy storage project located in Upington,Khara Hais, Northern Cape, 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 Rooipunt 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.
The Energy storage provides a non-intermittent electricity supply to meet South Africa’s peak demand requirements, day and night. Completely emission free, with no requirement for natural gas or oil back up. 750,000 tonnes of CO2 will be displaced each year. The Rooipunt 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).
