Eskom’s year‑long respite from load shedding marks a watershed moment for South Africa’s power sector, especially when contrasted with the 300‑day blackout streak of 2021 that crippled factories, disrupted schools and drove up living costs. The turnaround stems from a blend of aggressive maintenance, policy support and a surge in private‑sector generation, yet the journey toward a fully competitive electricity market remains unfinished.
Under CEO Dan Marokane, Eskom has rolled out its generation recovery plan, lifting the energy availability factor and cutting unplanned outages. The utility’s own data show a 15% rise in plant performance over the past twelve months, while pre‑emptive maintenance programmes—intensified since 2021—have reduced forced shutdowns by roughly 30%. Energy Minister Kgosientsho Ramokgopa has complemented these operational gains with a regulatory climate that encourages private investment, helping to diversify supply sources.
Private‑sector generators now play a pivotal role. The National Energy Regulator of South Africa (NERSA) reports over 2 300 registered facilities, delivering more than 18 GW of capacity and representing R360 billion in capital committed to the grid. Rooftop solar installations have also taken off, accounting for an estimated 10 % of South Africa’s total electricity production. These developments have eased pressure on Eskom’s aging fleet and contributed directly to the cessation of load shedding.
Independent transmission system operator: the missing piece of the reform puzzle
The next critical step is the establishment of an independent transmission system operator (TSO). Originally slated for an April launch, the TSO rollout has slipped, leaving Eskom as both generator and network manager—a situation likened to an airline that also controls every airport it serves. A truly competitive market hinges on a neutral entity that can grant equitable grid access to all producers, from large independent power producers (IPPs) to community solar schemes.
| Reform Element | Current Status | Target Milestone |
|---|---|---|
| Independent TSO | Not yet operational; deadline missed | Formal launch by Q4 2025 |
| Full Unbundling of Eskom | Partial separation of generation assets | Complete unbundling by 2026 |
| Wholesale Market Liberalisation | Limited third‑party participation | Open market with at least 5 major suppliers by 2027 |
| Debt Relief for Municipalities | R130 billion municipal arrears | Structured repayment plan over 10 years |
The table underscores that while generation reforms have delivered tangible results, transmission and market liberalisation lag behind. Accelerating the TSO’s creation will be essential to converting Eskom’s operational recovery into sustained, low‑cost electricity for households and industry alike.
Minister Ramokgopa’s next public address is expected to outline a concrete timetable for the TSO, and President Cyril Ramaphosa has already signalled that unbundling will proceed despite the financial complexities. Lenders are currently negotiating the terms of a possible “ring‑fencing” arrangement that would separate Eskom’s debt from its operational units, a move that could improve the utility’s credit rating and unlock cheaper financing for infrastructure upgrades.
Beyond the grid, Eskom’s balance sheet is still under strain from municipal non‑payment. Johannesburg alone owes R5.2 billion, contributing to a national municipal debt pile exceeding R130 billion. This represents the single largest financial risk to the utility and threatens to erode the gains made through improved plant performance. The city’s own challenges—intermittent water supply, failing street lighting and crumbling roads—compound the fiscal pressure on businesses that must now fund backup generators and private water storage.
Business leaders in Johannesburg have repeatedly warned that the city’s infrastructure woes are undermining South Africa’s broader competitiveness. When firms allocate a significant portion of their operating budgets to emergency power and water solutions, they lose the capacity to invest in growth, innovation and export potential. The mayor’s optimistic rhetoric in the recent State of the City address, which proclaimed Johannesburg “a city on the rise,” clashes with the lived reality of residents who contend with daily service disruptions.
The economic case for completing electricity market reforms
A fully liberalised electricity market would introduce price competition, giving consumers the ability to shop for power much like they do for mobile data or broadband. Industry analysts estimate that competition could shave 5‑10 % off average retail electricity tariffs within five years, translating to billions of rand saved for households and businesses. Moreover, an independent TSO would streamline the integration of renewable energy projects, accelerating South Africa’s transition to a lower‑carbon grid and helping the country meet its 2030 emissions targets.
Realising these benefits depends on decisive political leadership. Minister Ramokgopa must safeguard the reform agenda from institutional inertia, while municipal councils need to honour debt repayment schedules that keep the utility solvent. Without these commitments, the risk of demand outstripping supply resurfaces, and the hard‑won end to load shedding could dissolve into a new cycle of shortages.
Eskom’s recent performance boost—evident in the R9 billion diesel‑fuel saving and higher revenue from surplus generation—demonstrates what is possible when operational discipline meets supportive policy. However, the utility’s longer‑term health will be judged by its ability to operate in a market that rewards efficiency, not by its monopoly over the nation’s power wires.
As South Africans enjoy lights staying on, the story is far from over. The next chapters will be written by the speed at which the independent TSO is established, the rigor of municipal debt settlements, and the political will to see unbundling through to completion. If these reforms stay on track, the country can finally move from a fragile recovery to a resilient, competitive electricity system that powers growth for all.
