Anthem CEO James Cumming says there is a “high probability” of a battery energy storage system (BESS) being integrated into its massive 475 MWac (620 MWdc) Notsi solar PV project in the Free State, with the site having already been permitted to include BESS. The South African independent power producer started construction on the R9-billion project in March following financial close, which was concluded on the back of 20-year-plus offtake agreements with electricity traders Discovery Green and NOA.
