State-owned power utility Eskom indicated during a court hearing on Friday that it would not seek to recover more than R23-billion in additional revenue through the tariff during its 2021/22 financial year, implying that any possible hike implemented on April 1 would be capped at about 15.5%. However, Advocate Matthew Chaskalson, who acted for Eskom, told Justice Joseph Raulinga that any amount less than R23-billion would be financially unsustainable for the utility and potentially “socially disastrous”, as yet more fiscal resources would have to be diverted from other social needs to shore up Eskom’s finances.
