“South Africa has entered a pivotal stage in its energy transition as the Electricity Regulation Amendment Act (ERAA) begins to take practical effect, shifting the sector from a monopoly under Eskom to a competitive electricity market. With new transmission regulations and the upcoming launch of the South African Wholesale Electricity Market (SAWEM), the reforms promise to unlock private investment, expand renewable integration, and stabilize the grid.”
South Africa’s energy sector is undergoing its most profound transformation in decades. The Electricity Regulation Amendment Act (ERAA), which came into force in January 2025, is now entering its implementation phase in 2026. This reform dismantles the vertically integrated monopoly structure dominated by Eskom and introduces a competitive electricity market designed to attract private investment, diversify supply, and improve reliability.
Background: Eskom’s Legacy and the Need for Reform
For decades, Eskom has been the backbone of South Africa’s electricity supply, but its dominance has also been a source of systemic risk. Chronic load-shedding, underinvestment in infrastructure, and financial instability have underscored the need for structural change. The ERAA represents a decisive break from this legacy, creating a Transmission System Operator (TSO) to oversee system operation, market regulation, and transmission expansion.
Key Features of ERAA
- Competitive Market Structure: The Act establishes a framework for willing-buyer, willing-seller arrangements, enabling independent power producers (IPPs) to sell electricity directly to consumers.
- Expanded Regulatory Oversight: The National Energy Regulator of South Africa (NERSA) gains broader powers to oversee tariffs and market compliance.
- Transmission Regulations: Published in October 2025, these regulations clarify procurement processes for new transmission capacity, introducing build-operate-transfer models and value-for-money service agreements.
The Market Code and SAWEM Launch
The Market Code, finalized in early 2026, sets operational rules for the South African Wholesale Electricity Market (SAWEM). This includes frameworks for Day-Ahead, Intraday, Reserve, and Balancing markets, with a phased rollout beginning in April 2026 and full operation targeted by 2031. While delays remain possible, the code provides the legal certainty needed for private sector participation.
Implications for Renewable Energy
South Africa’s renewable energy sector stands to benefit significantly. IPPs will gain direct access to markets, reducing reliance on Eskom’s procurement processes. This is expected to accelerate the deployment of solar, wind, and battery storage projects, aligning with the country’s climate commitments and reducing dependence on coal.
Challenges and Risks
Despite optimism, several challenges loom:
- Tariff Ambiguities: Disputes over tariff approvals and definitions of “direct supply agreements” could lead to litigation.
- Municipal Resistance: The South African Local Government Association (SALGA) has raised concerns about municipal roles, potentially delaying implementation.
- Infrastructure Bottlenecks: Transmission expansion remains critical, with bottlenecks threatening renewable integration.
Regional and Global Context
South Africa’s reforms mirror broader trends across Africa, where countries are liberalizing energy markets to attract investment. The ERAA positions South Africa as a regional leader in energy transition, potentially influencing neighboring countries in the Southern African Development Community (SADC).
Conclusion
The ERAA marks a turning point in South Africa’s energy history. By opening the market to competition, strengthening regulatory oversight, and enabling renewable integration, the reforms promise to reshape the country’s energy landscape. Success, however, will depend on effective implementation, infrastructure expansion, and stakeholder cooperation.
