South Africa’s State power utility has failed to tap $2.5-billion of cheap loans to build critical transmission infrastructure that would help end the country’s crippling energy crisis. That’s brought a landmark climate finance agreement — the Just Energy Transition Partnership — to a virtual halt, and extends the country’s reliance on coal plants. Finance ministry pressure on Eskom Holdings SOC Ltd. to not take on new debt and a lack of clarity on how private investors can participate are hindering the deployment of about $7-billion of energy financing, according to a US Treasury official and six other people familiar with the situation.
