State-owned electricity utility Eskom continues to maintain that its revenue application, including the implementation of regulatory clearing account (RCA) decisions already made, would translate to a 20.5% increase in the standard tariff on April 1, rather than the 32.15% hike outlined in a ‘pro forma’ table produced by the regulator. The National Energy Regulator of South Africa’s (Nersa’s) figure, which has been shared with Engineering News & Mining Weekly, is based on revenue from standard tariff customers rising to R302.9-billion in 2022/23, from R245.7-billion in 2021/22.
