Eskom Unbundling Sparks Union Protests Across South Africa

Introduction

South Africa’s electricity sector is undergoing its most significant transformation in decades. The government’s plan to unbundle Eskom into separate entities for generation, transmission, and distribution has triggered widespread protests from trade unions. The National Union of Mineworkers (NUM), supported by COSATU, argues that the restructuring is a disguised form of privatization that threatens jobs, energy sovereignty, and affordability.

Background: Why Eskom Is Being Unbundled

Eskom has long struggled with debt, inefficiency, and aging coal plants. Rolling blackouts, known locally as load shedding, have crippled businesses and households. To address these challenges, the government announced a phased unbundling process. By mid‑2026, Eskom’s transmission division will be separated into a new independent Transmission System Operator (TSO). This operator will manage the national grid, implement the Market Code, and ensure fair access for independent power producers (IPPs).

The reform is intended to attract private capital, diversify South Africa’s energy mix, and modernize the grid. However, unions see it differently: as a pathway to privatization that undermines public control of electricity.

Union Resistance: NUM and COSATU Lead the Charge

The National Union of Mineworkers (NUM) has taken a firm stance against Eskom’s split. NUM leaders argue that thousands of jobs are at risk if transmission and generation are opened to private investors. COSATU, South Africa’s largest trade union federation, has endorsed NUM’s position, warning that restructuring could lead to higher tariffs and weaken state sovereignty over energy supply.

In a coordinated effort, NUM announced nationwide marches across all 11 regions of South Africa. These protests target Eskom offices and government departments, aiming to pressure authorities to halt the restructuring process.

Polokwane March: Limpopo at the Forefront

Limpopo has become a focal point of union resistance. On Saturday, 18 April 2026, NUM’s North East region will march in Polokwane. Protesters will gather at SABC Park at 9:00 AM before delivering a memorandum to Premier Phophi Ramathuba at noon. The memorandum outlines grievances against Eskom’s unbundling and calls for provincial leaders to intervene in national energy policy.

For Limpopo residents, the protest reflects broader anxieties about electricity affordability and job security. Communities dependent on Eskom-linked operations fear retrenchments and rising costs if privatization proceeds unchecked.

Union Concerns Explained

• Job Security: Workers fear mass retrenchments as private companies take over transmission and generation.
• Energy Sovereignty: Unions argue that unbundling opens the grid to private dominance, reducing state control.
• Privatization Risk: Transmission separation is seen as the first step toward selling Eskom assets.
• Tariff Uncertainty: Market-driven pricing could raise electricity costs for households and businesses.

Government’s Position

President Cyril Ramaphosa has defended the unbundling plan, stating that functional separation will improve efficiency and reliability. The government insists that the transmission operator will remain publicly owned, ensuring state oversight. Officials argue that unbundling is necessary to unlock renewable energy corridors and attract investment for grid expansion.

The Transmission Development Plan requires R390 billion over the next decade to upgrade infrastructure. Without private capital, the government warns, South Africa risks prolonged energy insecurity.

Risks and Trade-Offs

While unbundling promises modernization, it carries risks. Transition complexity could cause short-term instability. Securing R390 billion in investment is ambitious, and delays may stall grid expansion. Political resistance from unions could also undermine investor confidence, while communities may sympathize with unions if restructuring leads to higher tariffs.

Local Impact in Limpopo

Limpopo’s renewable potential, particularly solar and biomass, could benefit from new transmission corridors. Small-scale producers may gain opportunities to sell excess power into the grid under the new Market Code. However, these benefits hinge on successful implementation and fair regulation.

Conclusion

Eskom’s unbundling represents a structural shift in South Africa’s energy sector. For unions, it is a battle to protect jobs and preserve public control. For government, it is a necessary reform to modernize the grid. The outcome will shape South Africa’s energy future, balancing efficiency, affordability, and sovereignty.

As protests intensify, the government must negotiate carefully with unions to avoid destabilizing the transition. Job guarantees, phased restructuring, and transparent tariff regulation may offer pathways to compromise.
