State-owned electricity producer Eskom aims, within the coming months, to seek authorisation from its board and government to initiate a formal bidding process for the repurposing and repowering of the Camden, Komati, Grootvlei and Hendrina coal-fired power stations using lower-carbon generation technologies. All units at the four stations, which currently employ some 1 530 people directly, are scheduled to stop producing electricity between 2021 and 2028.
