Eskom Holdings has taken steps to protect its operations from disruptions after a contractual dispute with Oracle Corp.’s South African unit put its technical support services at risk. The state power utility confirmed on Monday that it’s involved in the disagreement in which Oracle initially claimed Eskom underpaid it by about R7.3-billion ($500 million). While the amount was later reduced between the parties, Oracle rejected Eskom’s settlement offer of 166 million rand and threatened to terminate its services, the power utility said in an emailed statement.
