Eskom has more than doubled its annual profit to R30.3 billion ($1.8 billion), driven by a sharp reduction in diesel expenditure and sustained financial relief from the South African National Treasury.
The utility’s financial recovery follows a period of chronic instability characterised by severe load shedding and mounting debt. The latest figures indicate a significant shift in the company’s cost structure, primarily due to a decrease in the use of expensive Open Cycle Gas Turbines (OCGTs).
According to the company’s financial disclosures, the reduction in “diesel burn” was made possible by improved generation stability across its coal fleet, which reduced the need to rely on diesel-powered peaking plants to prevent total grid collapse.
Financial support from the National Treasury also played a critical role in the profit surge. This relief includes debt write-downs and direct subsidies aimed at stabilising the utility’s balance sheet and ensuring the continued viability of the national grid.
While the profit figure is a positive indicator, analysts suggest it reflects a combination of operational improvements and accounting relief rather than a complete structural turnaround. The utility has spent years struggling with aging infrastructure and corruption, leaving it dependent on state intervention to avoid insolvency.
Industrial Demand Slump and Capacity Surplus
Despite the financial gains, Eskom is facing a new set of operational challenges. The utility has reported a capacity surplus of approximately 3GW, a stark contrast to the decade of deficits that triggered South Africa’s energy crisis.
This surplus is not entirely a result of increased generation efficiency. A significant driver is the decline in demand from the industrial sector. Many large-scale manufacturers and mining companies have invested heavily in their own renewable energy plants to bypass the unreliable national grid.
The shift toward embedded generation means that Eskom is losing its most lucrative customers. As industrial users migrate to solar and wind energy, the utility faces a long-term risk of declining revenue, which could undermine its ability to maintain the grid without further state subsidies.
The 3GW surplus also creates a financial paradox. Maintaining idle capacity incurs significant fixed costs, meaning the utility must manage its plant availability carefully to avoid wasting resources while ensuring it can still meet peak demand during winter months.
The utility’s future pricing remains a point of contention. The National Energy Regulator of South Africa (NERSA) continues to balance the need for Eskom to recover costs and invest in maintenance against the risk of pricing out the remaining industrial and residential consumers.
Current efforts are focused on the unbundling of Eskom into three separate entities: generation, transmission, and distribution. This process is intended to create a competitive electricity market, allowing private generators to sell power more easily through the national transmission network.
The next critical milestone for the utility will be the implementation of the new transmission company, which is expected to attract private investment into grid infrastructure. This move is seen as essential for integrating more renewable energy into the system and reducing the overall burden on the state’s finances.
