South Africa's Eskom Chair Steps Back as Transmission Split Looms: What Comes After the Blackout Crisis

Mteto Nyati's tenure as chair of Eskom, South Africa's state-owned power utility, is expiring, and his future at the utility is uncertain. ^[1] The timing matters because Eskom has just climbed out of a 17-year energy crisis that left South Africa under rolling blackouts; ^[5] the utility is predicting it will return to profitability for the first time since 2017, ^[5] and Nyati has signaled confidence that the institution can survive without him. ^[1] But the real test is not Nyati's departure. It is whether South Africa can execute a structural separation of transmission assets while keeping the reforms intact.

Here is the mechanism: South Africa's government has committed to establishing an independent Transmission System Operator (TSO) by no later than December 31, 2029, under the Electricity Regulation Act. ^[4] The move mirrors reforms that utilities in Europe, Australia, and parts of the United States have undertaken to separate monopoly control of the grid from the generation and retail operations that sit on top of it. The separation is supposed to reduce the incentive for a dominant utility to favor its own generation fleet and to allow independent generators, including renewables and distributed solar, to access the grid on neutral terms. It is, in principle, the right structural move for a country trying to escape the energy poverty that blackouts created.

But Nyati and Eskom's board are publicly cautioning against rushing the asset transfer. ^[4] Nyati has warned that moving transmission assets too quickly could destabilize Eskom's balance sheet and spook lenders at a moment when the utility is rebuilding creditworthiness. ^[4] The board's position is that functions of the TSO should be established and operated first, with ownership of the physical grid transferred only after Eskom's financial position stabilizes. ^[4] This is a recognizable play: the incumbent argues that speed will break the institution, so gradualism is prudent governance. Critics question whether the debt argument reflects genuine financial risk or is cover for delay. ^[4]

The stake is whether South Africa's next board chair and the government's electricity minister, Kgosientsho Ramokgopa, who oversees Eskom as the shareholder representative ^[1], will hold the line on the December 2029 deadline or allow it to slip. Eskom has cycled through ten CEOs in ten years, ^[6] a turnover that mirrors the instability American utilities engineer in oversight bodies when they want to avoid structural change. Each new leader inherits the crisis narrative and the argument that solving it requires patience. The TSO separation is not Nyati's to complete; it is the test of whether his successor and the minister will finish what he started.

The international pattern here is clear. Australia separated transmission from generation in the 1990s and built a national wholesale market operator; that separation is now the frame for independent renewables investment and household solar aggregation into virtual power plants. Europe's energy-market reform of 2024 pushed member states toward independent transmission operators as a prerequisite for decarbonization. The lesson is not that separation is easy or fast, it never is, but that delay has a cost: utilities that control both transmission and generation have every incentive to constrain open access and to defend incumbent power sources. Nyati's warning about balance-sheet risk is not wrong, but the counter-risk is equally real: if the TSO separation stalls, South Africa's next energy transition will run through Eskom's self-interest rather than through the grid itself.

The immediate question is whether Cabinet will extend Nyati's term or name a successor aligned with faster or slower separation. ^[1] The deeper question is whether South Africa will treat transmission as a strategic public asset (in which case separation is non-negotiable and the financial engineering to support it is secondary) or as a liability to be managed by the incumbent (in which case every delay is justified by prudence). The country has already paid the price of the second choice.
