State-owned electricity utility Eskom says it will make a final revenue application to the National Energy Regulator of South Africa (Nersa) this month, but has confirmed that the application will be for a “double digit” tariff increase for implementation on April 1, 2018. Business news website Moneyweb reports that it has had sight of a confidential draft application, in which Eskom outlines the case for a 19.9% hike for 2018/19. The utility would not be making a multiyear application, owing to ongoing legal uncertainty related to the regulator clearing account (RCA) mechanism, following a 2016 Gauteng High Court ruling, which determined the most recent RCA adjustment to be “irrational, unfair and unlawful”.
