The struggling utility supplies more than 90 percent of the electricity in Africa's most industrialised economy but has a 420 billion rand debt which it struggles to service, poses a threat to the country's credit rating.
Eskom said it had secured 52% of its plan to borrow 46 billion rand during the 2019/20 financial year.
Eskom had expected to draw down 7 billion rand ($481 million) from a $2.5 billion CDB loan facility by late March, but South Africa's finance ministry said last month that the drawdown had been delayed, meaning a planned bailout had to be brought forward.
The company said its liquidity stood at 7.7 billion rand at April 30, 2019. President Cyril Ramaphosa has prioritised fixing the ailing utility in his new five-year term with government having pledged a 23 billion rand ($1.6 billion) a year bailout for Eskom over the next three years.
