South Africa: South African Wholesale Energy Markets Transform

• South Africa's energy system is currently stable, with no load-shedding for over a year, supported by sufficient generation capacity.
• Approximately 20 gigawatts of new, mostly renewable, generation projects are planned for construction within the next three to five years.
• Amendments to the Electricity Regulation Act of 2006, gazetted in 2021, formalized electricity wheeling, allowing independent power producers to supply third-party consumers via the national grid.
• The National Transmission Company South Africa has been established as part of Eskom's unbundling to facilitate investment in new transmission infrastructure.
• The country anticipates the introduction of South African wholesale energy markets during the third quarter of 2026, with a phased opening through 2027, fostering a more competitive and sophisticated energy trading environment.

The impending introduction of South African wholesale energy markets is set to fundamentally reshape how energy is traded, moving beyond traditional bilateral agreements and government-centric procurement.

South Africa's energy sector is undergoing a significant transformation, with current conditions indicating a period of relative stability. For over a year, the nation has not experienced load-shedding, a direct result of sufficient energy generation meeting demand. This stability, however, is viewed as contingent on the pace at which Eskom's aging coal-fired power stations are decommissioned and the simultaneous integration of adequate renewable energy capacity to fill any resulting supply gaps.

Looking ahead, a substantial pipeline of new generation projects, predominantly in the renewable sector, is poised to come online. The South African grid presently boasts approximately 55 gigawatts of generation capacity, with an additional 20 gigawatts of new projects already registered. These initiatives, largely focused on renewables, are slated to commence construction within the next three to five years. This influx of independent power is already contributing to a more diversified energy mix, with close to 30% of the country's electricity now originating from renewable sources, a significant portion of which is sold directly to private buyers, thereby increasing market competition.

A key development facilitating this shift is the formalization of South Africa electricity wheeling. This mechanism allows for the independent production of power at one location, its injection into Eskom's national network, and subsequent consumption by a third-party customer situated elsewhere, with direct financial transactions between the independent power producer and the consumer. This process is essentially an accounting treatment, meticulously metering both the power added to and drawn from the grid.

The legal foundation for this evolving energy market was significantly strengthened by amendments to the Electricity Regulation Act of 2006, which were gazetted in 2021. These legislative changes were instrumental in opening the door for energy wheeling, providing the necessary regulatory clarity for independent power producers to utilize the national grid. A notable early example of this framework in action was SOLA Group's supply agreement with Amazon Web Services in November 2021, marking the country's inaugural solar energy wheeling project.

Initial concerns regarding potential funding shortages for renewable energy projects have largely been allayed. South African commercial banks have demonstrated robust financial backing, providing strong lines of funding for these initiatives. In the past year alone, investments totaling approximately R60 billion, or potentially more, have been channeled into renewable energy projects. This financial commitment underscores the growing confidence in the sector's viability and expansion.

Illustrating the scale of these developments, SOLA Group is currently constructing a 300-megawatt solar facility in the Free State. This substantial project occupies an area roughly equivalent to 700 football fields, spanning approximately five square kilometers, highlighting the physical footprint required for large-scale renewable energy generation.

Despite the enthusiasm for new energy production, a critical bottleneck remains the physical integration of this power into Eskom's national transmission network. The grid has experienced limited investment over several decades, making it increasingly challenging to identify suitable points for injecting new generation capacity. This constraint is a significant hurdle to the continued expansion of the SA renewable energy market.

To address this, the unbundling of Eskom's transmission network is actively underway, with the National Transmission Company South Africa (NTC SA) having been formed and operational since 2023. This new entity is tasked with collaborating with the private sector to attract vital investment for developing new transmission infrastructure. The goal is to enhance grid capacity and facilitate the connection of a greater number of independent power projects, thereby alleviating the current injection limitations.

The South African energy market is poised for further profound evolution, with the impending introduction of South African wholesale energy markets scheduled to open during the third quarter of 2026 and phase in through 2027, set to fundamentally reshape how energy is traded, moving beyond traditional bilateral agreements and government-centric procurement. This shift will foster more sophisticated and advanced methods for buying and selling all types of energy, including renewables, ultimately creating a more competitive environment where Eskom is no longer the sole producer of electricity for the nation.

Lawyers and compliance officers should monitor the impending introduction of South African wholesale energy markets and evolving grid access regulations, as these developments will necessitate new contractual frameworks and compliance strategies for clients involved in energy production, procurement, and investment.
