“This is the first part of the 500MW Bess initiative announced by President Cyril Ramaphosa as part of government’s measures to address South Africa’s long-running energy crisis,” a statement from the company read.

According to Eskom, the technology should reduce strain on the national grid, particularly during periods of high demand, for at least four hours each day and for at least 250 days each year. Additionally, it will be utilized secondarily for local network support and related services, according to techcentral.co.za.

When network conditions allow, or during off-peak hours, the battery system will be charged. Large-scale utility batteries will be used for the project, which will be carried out in two stages:

The installation of an additional 199MW of capacity is part of the first phase. This translates to 833MWh storage at eight Eskom distribution substations with four hours of storage. About 2MW of solar PV will also be installed during this phase.

At four Eskom distribution sites and one transmission site, 144MW of capacity—or 616MWh—will be installed as part of the second phase. This phase will also include the installation of 58MW of solar PV.

By June 2023, phase 1 sites will be operational, and phase 2 sites by December 2024.
