South Africa experienced just four days of load shedding in the financial year ended March 2026 — down from 329 days the prior year — and Eskom banked that operational recovery into a net profit of approximately $1.9 billion (R30.3 billion), more than double the R14 billion it earned the previous year, according to Business Insider Africa. It marks only the second consecutive profitable year for Africa's largest electricity producer after nearly a decade of losses.
The arithmetic behind the profit is straightforward: fewer blackouts meant Eskom could sell power more consistently and spend less on expensive emergency generation measures. An average tariff increase of 12.7% added to the top line. But those gains coexist with a structural problem the income statement cannot hide — the customers buying the electricity, particularly municipalities, are paying less of what they owe.
Sales volumes actually fell 6.2% during the year, even as tariffs rose. Business Insider Africa reports that higher prices, the proliferation of private rooftop solar installations, energy efficiency investments, and sluggish economic activity are all reshaping demand. Eskom's published results do not disaggregate exactly how much each factor contributed, but the direction is unmistakable: the utility is extracting more revenue per unit sold into a market that is consuming fewer units overall — a squeeze that limits how far tariff hikes can carry financial performance.
The more acute threat sits in the municipal debt ledger. South African municipalities purchase bulk electricity from Eskom, resell it to households and businesses, and are expected to remit Eskom's portion of the collections. Many are not. Outstanding municipal debt reached approximately $6.9 billion (R111.6 billion) by the end of the financial year — a figure that has been climbing for years and that Eskom describes as one of the largest risks to its recovery. Municipal and metropolitan customers represent more than 40% of Eskom's electricity sales, so this is not a localised billing dispute; it is a structural leak at the centre of the national power economy.
Johannesburg provides the starkest illustration. Eskom has already threatened to cut supplies to the city after its arrears with City Power reached approximately $408 million. If Johannesburg — the continent's wealthiest city by economic output — cannot settle its account, the signal to smaller, fiscally weaker municipalities is corrosive. Eskom warns that without significant intervention, total municipal debt will balloon to roughly $22.2 billion (R358 billion) by 2031. For context, Eskom's current gross debt stands at approximately $22.1 billion — meaning the projected municipal arrears in five years would equal the utility's entire borrowing load today.
Eskom's improved balance sheet also carries a government subsidy embedded within it. Pretoria approved a multiyear debt-relief package designed to let the utility invest in maintenance while shrinking its debt burden. That support has been material to the turnaround; stripping it out would present a more sobering picture of underlying commercial performance. Coal-fired power stations — still the backbone of South African generation — continue to require extensive capital investment, and the return to financial health has not changed that long-term capital requirement.
For businesses and investors operating in South Africa, the results offer a mixed read. The collapse in load shedding has already reduced the operational drag on manufacturers, retailers, and logistics companies that spent the previous two years running diesel generators and absorbing production losses. That normalisation is real and meaningful for near-term profitability across sectors. But the municipal debt trajectory, and the implicit threat of supply cuts to non-paying cities, introduces a new category of operational risk: power interruptions driven not by generation failure but by a billing and governance crisis in local government.
Private energy developers and rooftop solar financiers should read the 6.2% volume decline as confirmation that corporate and middle-income household defection from the grid is accelerating. Eskom can raise tariffs to compensate, but each increase reinforces the economics of self-generation for those who can afford the upfront capital — leaving a shrinking, lower-income base cross-subsidising municipal debtors and grid infrastructure. That dynamic is the core tension inside an otherwise impressive headline number.
Why it matters: Eskom's $1.9 billion profit is a genuine operational milestone, but the $6.9 billion municipal debt — on a trajectory to match the utility's entire gross borrowing by 2031 — means the recovery is structurally incomplete. Any investor, lender, or corporate energy buyer pricing South African power risk over a five-year horizon cannot treat the headline profit as a clean signal; the municipal arrears problem is large enough to reverse the turnaround entirely if it goes unresolved.
