Investors in Eskom are on high alert for finance minister Enoch Godongwana’s plan to reorganise its mountain of debt.

Between one- and two-thirds of Eskom’s liabilities of about R400-billion are expected to be transferred to the state’s balance sheet, with the amount and some of the transfer terms likely to be announced in the national budget on Wednesday.

The government guarantees about 80% of Eskom’s loans and 13 of 17 economists surveyed by Bloomberg say it can take on at least half of the utility’s obligations without compromising efforts to reduce state debt and budget deficits.

Reducing Eskom’s obligations will free up funds for the utility to carry out plant maintenance and strengthen the power grid, which could lessen the severity of daily power outages. It will also add to the state’s debt burden of almost R5-trillion and to its repayment costs, which consume about 18% of main budget revenue.

National treasury is expected to make the relief contingent on Eskom meeting performance targets. Godongwana has previously said the transfer of funds to the state’s balance sheet will be staggered and that Eskom’s bondholders won’t be asked to accept losses, which would be tantamount to a default.
