South Africa’s utility Eskom is preparing to launch a tender for 1.4 gigawatt-hours of battery storage that will need to be installed by December 2021.

The large-scale energy storage tender, the first of its kind in the country and in Africa as a whole, will be split into two phases, with an initial 200 megawatts/800 megawatt-hours of capacity to be built by December 2020, an Eskom official said. 

This first phase of implementation will be divided into four packages, and will be followed by 160 megawatts/640 megawatt-hours to be installed a year later, Prince Moyo, general manager for power delivery engineering at Eskom, said during a Wednesday webinar.

The second phase will include 60 megawatts of solar to be integrated with the battery storage, along with an asset performance management system.
