Eskom Holdings, South Africa’s State power utility, doesn’t want to buy electricity from the company that won most of a government emergency-power tender because it’s concerned about the cost and length of the contract, according to two people familiar with the situation. Meeting the terms of Karpowership’s 20-year deal would add pressure to Eskom’s already stretched finances and heighten its exposure to fossil fuels, said the people, requesting anonymity as the utility is yet to comment publicly. The company has a debt burden of R464-billion and is struggling to meet payments even with the help of State bailouts.
