The National Energy Regulator of South Africa (Nersa) has invited stakeholder comment on a proposed 10-year negotiated pricing agreement (NPA) between Eskom and the Hillside aluminium smelter, in KwaZulu-Natal, which is owned by South32 and is Eskom’s largest single customer. The proposed NPA is likely to attract much public scrutiny in light of the fact that the previous tariff agreement between Eskom and Hillside had been the subject of years of intense public scrutiny and criticism, including one proposal that supply to the smelter be terminated as a way of addressing growth-sapping load-shedding.
