Eskom has officially started operating the first of eight utility-scale battery energy storage system (BESS) projects being introduced as part of Phase 1 of a World Bank-funded programme to add batteries with a combined storage capacity of 199 MW and the ability to discharge 833 MWh of electricity over a minimum of four hours. The project in question is the 20 MW/100MWh Hex BESS site, which has been built on Eskom’s distribution network in Worcester in the Western Cape using batteries supplied by Hyosung, of South Korea.
