The government of the Republic of South Africa is set to construct an 80 MW/320 MWh battery energy storage system in Vredendal, Western Cape Province. This is after Eskom, a state-owned electricity utility, launched a call for expressions of interest for the deployment of the facility at Skaapvlei substation.
The deadline for the submission of the project proposals is September 11 this year after which following a strict selection process the successful bidder will sign a contract to design, build and commission the storage facility within a period of seven and nine months. They will further operate and provide maintenance services for a period of five years.
Upon completion, the battery energy storage system facility is intended to help manage intermittent power generated by the nearby 100MW Sere Wind Farm Project
