A plan to establish the world’s largest green-energy financing initiative is being threshed out in South Africa, which needs to reduce its environmental footprint and find innovative ways to fund debt-stricken state power utility Eskom Holdings. The plan being formulated by Meridian Economics, a Cape Town-based think tank, is under consideration by the government. It envisions the establishment of an $11-billion facility backed by development finance institutions and private funders. The new entity would lend money to Eskom at slightly below commercial rates on condition it accelerates the closure of polluting coal plants to make way for renewable energy.
