Mineral Resources and Energy Minister Gwede Mantashe says cutting the proposed contract periods with Karpowership from 20 years to 10 years could help government realise its ambitions to procure energy urgently from the floating power stations. Mantashe was speaking at an ANC Energy Dialogue held in Johannesburg on Tuesday, during which Eskom announced that Stages 4 and 5 load shedding would be implemented until Sunday.
