Hyosung Heavy Industries and Pinggao Group are the first companies contracted to provide large lithium-ion batteries to Eskom for its massive battery energy storage system .
Eskom chose the preferred bidders after issuing an open tender to the market for the project’s first phase, following a procurement process by the World Bank, which is providing funding for the BESS.The utility said the companies underwent an intensive evaluation process using criteria issued as part of the bidding documents.
The system will primarily be used to shave peak national load for four hours per day on at least 250 days of the year, helping reduce the likelihood of load-shedding.The system will then discharge energy to the grid during peak periods when demand is higher.
