How much more middle-class South Africans will pay for electricity this month Subscribe Middle-income South Africans will pay significantly more for electricity this month as Eskom electricity tariffs increased by 15.63% on 1 April. This comes after the power utility and the National Energy Regulator of South Africa (Nersa) reached an agreement on Eskom’s allowable revenue for the 2021/2022 financial year. These price hikes are already filtering through to end-users in different municipalities, as seen with recent price adjustment notifications from areas like the City of Joburg. FNB said that it expects these hikes to hit middle-income households particularly hard, and that families will have to review their already stretched budgets to keep the lights on.
