State-owned electricity group Eskom says the National Energy Regulator of South Africa’s (Nersa’s) latest regulatory clearing account (RCA) determination for the 2018/19 financial year contains “some encouraging decisions”, highlighting its treatment of coal costs as representing a particularly “significant shift”. Nevertheless, the utility told Engineering News & Mining Weekly that it would only be in a position to make a call on whether it would take the decision on legal review once it received clarity through the reasons for decision.
