Group wind power generation last year increased by 8% and the Lephalale solar power project is on its way to being operational in the first quarter of next year, Exxaro CE Dr Nombasa Tsengwa highlighted during the company’s presentation of double-dividend 2023 results. The increased wind performance resulted in 727 GWh of high-margin green electricity being generated into the market at a high earnings before interest, taxes, depreciation and amortisation (Ebitda) margin – and, were it not for a fault that occurred on the distribution network of State-owned power utility Eskom, there would have been 15 GWh more.
