The Organisation Undoing Tax Abuse (Outa) has released an alternative to Eskom’s proposed retail tariff plan (RTP) ahead of public hearings into the plan, which proposes far-reaching changes to the residential tariff structure that some warn could penalise households with rooftop solar. The National Energy Regulator of South Africa (Nersa) will host virtual hearings into Eskom’s proposed RTP on January 23, having postponed the hearings from the initial December 18 date set.
