The National Energy Regulator of South Africa (Nersa) has authorised the national power utility Eskom to increase its tariff by an average of 9.61% for the 2022/23 financial year. The tariff increase includes 3.49% for the 2022/23 year as well as legacy decisions from previous years, which brings it to 9.61%. Eskom had previously asked for a 20.5% tariff increase for 2022/23 as most of the cost increase was driven by the requirement to increase purchases of energy from independent power producers (IPPs) and the increase in carbon taxes. In December 2021, Eskom secured a court order that Nersa considers the 2022/23 application immediately, to apply the tariff increase as of 1 April 2022 rather than as of 1 July 2022.
In February 2021, Nersa had authorised Eskom to increase its tariff by an average of 15.6% for the 2021/22 financial year.
