Karpowership, the world’s biggest supplier of floating gas-fired power plants, said some South African government agencies have stalled its projects and their conduct isn’t conducive to creating an attractive investment environment. The Turkish company in March last year won the right to supply South Africa with 1,220 megawatts of electricity, or more than 60% of a so-called emergency tender designed to ease intermittent power outages. The 20-year deal was valued at 218 billion rand ($14 billion) at the time.
