South Africa: Eskom Market Dominance Regulation Proposed

• South Africa's government released the "Electricity Sector Market Transformation paper" proposing a competitive wholesale electricity market.
• The plan aims to monitor and potentially regulate Eskom's market dominance, treating its generation unit equally with other producers.
• A new South African Wholesale Electricity Market (SAWEM) will launch by 2027, overseen by a market operator, Nersa, and the Competition Commission.
• The reforms seek to increase efficiency, investment, and competition in the electricity sector to address load shedding and financial issues.
• Short-term (day-ahead) and long-term (up to 20-year) markets will facilitate transactions for bulk buyers.

To prevent any single entity, including Eskom Generation, from distorting market outcomes, the government plans to review and implement robust mechanisms designed to limit the exercise of market power.

The South African government has unveiled a comprehensive strategy aimed at transforming the nation's electricity sector, proposing a competitive wholesale market to address long-standing structural challenges. Minister of Electricity and Energy, Kgosientsho Ramokgopa, released a pivotal discussion document, the "Electricity Sector Market Transformation paper," on August 21, outlining a future where private power generators and Eskom compete on an equal footing to supply bulk buyers, including municipalities and traders. This initiative seeks to foster efficiency within the generation segment, which has historically suffered from limited competition.

Central to this vision is the establishment of the South African Wholesale Electricity Market (SAWEM), a centralized, voluntary platform designed to facilitate transactions. While SAWEM will serve as a primary hub, the framework also allows for buyers and sellers to engage in transactions outside this formal market. This proposed overhaul is presented as a critical reform to mitigate issues such as persistent load shedding and Eskom's financial underperformance, aiming to improve investment in power generation, enhance price competition, and bolster the security of supply across the country.

A key focus of the government's reform agenda is the management and potential regulation of Eskom's significant market dominance in electricity generation and sales. Having held a near-monopoly for over a century, Eskom is currently undergoing a structural unbundling into three distinct units – generation, transmission, and distribution – with its generation business slated to operate as a legally separate entity under Eskom Holdings. The "Electricity Sector Market Transformation paper" explicitly states that the future market operator will apply the same rules and obligations to Eskom Generation as to all other market participants, ensuring a level playing field.

To prevent any single entity, including Eskom Generation, from distorting market outcomes, the government plans to review and implement robust mechanisms designed to limit the exercise of market power. This includes the establishment of sophisticated market monitoring and surveillance systems specifically tasked with detecting potential abuses. Furthermore, the National Energy Regulator of South Africa (Nersa) is earmarked to develop and implement specific regulations for Eskom Generation, should it be deemed necessary to curb its ability to exert undue influence, even with the new competitive wholesale markets and surveillance in place. The government also intends to evaluate whether additional measures beyond direct regulation might be required to safeguard customer interests against Eskom's potential dominance.

The proposed South African Wholesale Electricity Market will be underpinned by a clear regulatory and operational structure. A dedicated market operator will be appointed to facilitate transactions between buyers and sellers, ensuring the smooth functioning of the new system. Nersa will play a crucial oversight role, responsible for regulating the market and protecting consumer interests, including the development of specific regulations for Eskom's market power. In instances where anti-competitive conduct is suspected within the electricity market, the Competition Commission will possess the authority to intervene or initiate investigations, reinforcing the commitment to fair competition.

The market design envisions both short-term and future markets. Initially, day-ahead markets will be established, allowing participants to transact for electricity production one day in advance, thereby improving the matching of supply and demand. A future market will then enable longer-term contracts, ranging from week-long agreements to those spanning up to 20 years, while respecting existing contracts, including those under the Independent Power Producers Procurement Programme (IPPPP). The government aims to launch the wholesale market by 2027, with a phased approach to gradually expand participation beyond Eskom. While ordinary household customers will continue to purchase electricity as they do currently, wholesale customers will be required to meet specific prudential requirements to ensure their financial and contractual obligations can be fulfilled.

These sweeping reforms are designed to fundamentally reshape South Africa's electricity landscape, moving away from a historically centralized model towards a more dynamic and competitive environment. The government's explicit intention is to significantly increase efficiency within the generation sector, a segment that has long been characterized by limited entry points for independent power producers. By fostering genuine competition, the "Electricity Sector Market Transformation paper" anticipates a surge in investment in new power generation capacity, leading to more competitive pricing and, ultimately, enhanced security of supply for the nation.

The discussion paper, which is open for public comment for a period of 30 days, represents a critical step in the ongoing efforts to modernize South Africa's energy infrastructure. It signals a clear commitment to dismantling the legacy of Eskom's century-long monopoly and establishing a robust, multi-participant electricity market. The success of these reforms hinges on the effective implementation of the proposed regulatory oversight by Nersa and the Competition Commission, ensuring that the intended benefits of increased competition and improved service delivery are realized for all stakeholders.

Lawyers advising clients in the South African energy sector should closely monitor the development of regulations stemming from the Electricity Sector Market Transformation paper, especially regarding Eskom's market power and potential anti-competitive practices. Compliance officers must prepare for new market rules and potential interventions by Nersa or the Competition Commission as the wholesale market is established.
