Karpowership, a unit of the Turkish Karadeniz Energy Group, is on track for its longest contract to date to supply power from vessels to South Africa in a deal worth as much as R218-billion ($15-billion). The company that advertises a “fast, flexible, reliable” solution of floating electricity generation was named last week as a preferred bidder for three projects fueled by liquefied natural gas to provide 1 220 MW of electricity. The program is aimed at closing a supply gap in South Africa that’s resulting in periodic blackouts.
