State-owned electricity utility Eskom will make the case later this month for the immediate execution of a High Court order stipulating that an amount of R23-billion stripped unlawfully from its allowable revenue in 2019 by the National Energy Regulator of South Africa (Nersa) be added back during its 2021/22 financial year. Should it succeed, the standard average electricity tariff would rise by 15.6% on April 1, instead of the 5.01% already sanctioned by Nersa.
