Another dispute may be looming between Eskom and the National Energy Regulator of South Africa (Nersa). This one, over the regulator’s decision to approve ArcelorMittal South Africa’s (AMSA’s) applications for six-year negotiated pricing agreements (NPAs) for its Newcastle and Vanderbijlpark operations. In a statement, Nersa noted that Eskom had rejected the applications made by AMSA in September and October last year on the basis that the utility did not agree that they met the criteria for such tariff relief.
