Karpowership, the Turkish company seeking to supply 1 220 MW of electricity to South Africa, had one of three appeals against adverse environmental rulings rejected, a person with knowledge of the matter said, potentially delaying a solution to the country’s power crisis. The Department of Forestry, Fisheries and the Environment rejected the appeal to moor a ship-mounted power plant capable of generating about 450 MW at the Coega harbor in the Eastern Cape province, the person said. Decisions on plants planned at the Saldanha and Richards Bay harbors have yet to be communicated to the company, the person said, asking not be identified because the government hasn’t made the information public.
