The National Energy Regulator of South Africa (Nersa) has formally initiated the process of adjudicating Eskom’s next tariff increase with the publication of a consultation paper on the utility’s allowable revenue application for 2023/24 and 2024/25. The paper includes a pro forma tariff calculation indicating that Eskom’s tariff could increase by as much as 38.1% on April 1 next year, followed by a further 5.12% increase in 2024/25.
