The National Energy Regulator of South Africa (Nersa) on 3 October announced that the Regulatory Clearing Account (RCA) balance of R7.82bn ($616m) that it approved on 30 July will be recouped by a one-off increase in the tariff in 2015-16. Nersa said that “standard tariff customers as well as other Eskom customer categories” will see their rates rise by 12.69%, rather than the 8% approved under the third multi-year price determination (MYPD3). The standard tariff refers to a range of tariffs relating to customers in urban areas with a maximum demand of 100kVA, who are among the most costly to service, Eskom told African Energy.
