Eskom Holdings, the South African power utility struggling with almost $30-billion in debt, said it will take as long as three to five years to comply with the government’s plan to split the company into three separate units. President Cyril Ramaphosa said in February that the company would be divided into generation, transmission and distribution units to make it more manageable. The split is part of a rescue plan that also committed the government to pay $8.4 billion over three years in bailouts.
