Eskom is requesting the National Energy Regulator of South Africa (Nersa) to approve diesel costs of R16.9-billion for its upcoming financial year in line with a material upward revision in the assumed load factor of its diesel-fuelled open cycle gas turbines (OCGTs) from 5% to 12%. The increase is designed to accommodate a steep reduction in the expected energy availability factor (EAF) from the State-owned utility’s coal-dominant fleet, which has been reduced to 59%.
