Eskom, South Africa’s state-owned utility, will be issuing a call for tenders for a large-scale battery-powered electricity storage project, according to Prince Moyo, Eskom’s General Manager of Energy Delivery Engineering.
A timeline for the project was not released, but it is expected to be implemented in two phases with an estimated capacity of 1.4 GWh. The first, which will be inaugurated in 2020, will install the batteries to store 800 MWh of electricity (200 MW). These batteries will be installed in four sets. For a storage capacity of 640 MWh (160 MW), the second phase of the Eskom project will be implemented before the end of 2021.
According to Eskom, bidders will be evaluated on the basis of the total cost of their proposals. For the implementation of this project, the World Bank is expected to provide Eskom a $1 billion loan.
