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.

The tender has already been approved by South Africa’s Ministry of Finance, Moyo said. The only ministry that has not yet signed off is the Department of Public Enterprises, Moyo added. That consent “has been escalated to the highest level,” he said, without committing to a launch date for the solicitation. “It’s imminent,” he said.
Moyo called the battery tender “a flagship project” for Eskom, which supplies around 90 percent of South Africa’s electricity via more than 45 gigawatts of generation. “We are moving toward cleaner power,” he said.
