Eskom CFO Calib Cassim told lawmakers on Tuesday that the State-owned utility had spent R18-billion on diesel for its current financial year-to-date, which began in April last year, and that it would probably need to spend another R4-billion until the end of March, raising the overall diesel spend for the year to R22-billion. The utility was continuing to operate its diesel-fuelled open-cycle gas turbines (OCGTs) despite having announced in November that it was no longer in a financial position to do so.
