South Africa’s electricity market has gained a new independent trader, with EPIX commencing operations in August 2026 after receiving approval for the transfer of Investec’s energy trading licence, creating a platform intended to connect renewable energy generators with commercial and industrial electricity buyers.
Established as an equal joint venture between Energy Partners and Investec, EPIX combines financing capability, renewable generation sourcing and established business customer relationships to offer tailored electricity procurement solutions. The company’s launch comes as South Africa expands private-sector participation in electricity supply and develops arrangements that allow businesses to purchase power from independent generators through the national grid.
The platform’s immediate focus is on commercial and industrial customers in sectors including mining, manufacturing, food and beverage, logistics, retail and property. Rather than relying on a single generation source, EPIX intends to combine electricity from different renewable facilities and match supply arrangements to customers’ consumption profiles, commercial requirements and sustainability objectives.
Mpho Modise, managing director for generation at EPIX, said the platform was established to connect renewable generators with commercial and industrial buyers while supporting competition and private investment in South Africa’s electricity sector. The company says its independence from any single project developer or technology allows it to source electricity from a wider pool of qualifying renewable energy generators.
Investec contributes funding capacity, market relationships and experience in sourcing large-scale renewable generation, while Energy Partners brings industrial and commercial customer relationships, technical expertise and energy management capabilities. The joint venture structure is intended to link demand for electricity with generation projects and the capital required to develop them.
The transfer of Investec’s energy trading licence to EPIX, approved by the National Energy Regulator of South Africa (NERSA) in June 2026, enabled the new platform to begin trading. Its first generation facility commenced trading on 15 August, according to the company, while a second facility is expected to join the portfolio. The announcement does not specify the facilities’ capacities or the volume of electricity currently contracted to customers.
EPIX plans to use electricity wheeling to supply customers across major economic sectors. Wheeling allows electricity generated at one location to be allocated to a customer connected elsewhere through existing transmission or distribution networks. The transaction involves contractual and financial arrangements that account for the electricity generated and consumed; it does not mean that the same physical electrons travel directly from a particular renewable plant to an individual customer.
For businesses, the model can create access to renewable electricity without requiring them to own or operate generation assets on their own premises. It can also allow companies with multiple facilities to contract for power from larger renewable projects located in areas with suitable generation resources.
Eskom’s wheeling framework sets out requirements involving grid access, network charges, connection arrangements and agreements between generators and customers. The practical availability of wheeling depends on these arrangements, as well as the capacity of the relevant network and the applicable regulatory requirements. Network constraints and administrative processes can therefore affect how quickly new generation and customer contracts are brought into operation.
The broader policy environment is also evolving. South Africa has been developing electricity trading rules and the South African Wholesale Electricity Market framework as it moves towards a more competitive electricity system. The market transition is intended to widen participation beyond the traditional vertically integrated supply model, but its effectiveness will depend on clear trading and settlement rules, fair grid access, reliable infrastructure and workable arrangements between traders, generators, network operators and customers.
EPIX’s launch adds another intermediary to a market in which licensed traders can aggregate supply and demand, structure transactions and help businesses navigate renewable energy procurement. For independent power producers, such platforms may provide access to a broader customer base without requiring every generator to negotiate separately with each potential buyer. For customers, the value will depend on the competitiveness of contracted prices, the reliability of supply arrangements and the terms governing delivery and settlement.
Charl du Plessis, managing director for business development at EPIX, said the company expects to procure electricity from its generation facilities and wheel it to customers across South Africa’s major industries. He described demand for flexible renewable electricity as part of a wider effort by businesses to improve energy resilience while meeting sustainability objectives.
The company intends to broaden its supply portfolio beyond solar generation. Its near-term plans include integrating wind, hydroelectricity and battery energy storage, with the aim of improving flexibility and increasing the share of renewable electricity available to customers. The timing and scale of that expansion will depend on generation projects becoming available, commercial agreements and the ability of the grid to accommodate additional supply.
Wind power is expected by EPIX to become more important as transmission constraints ease and additional projects are commissioned. Wind and solar generation can complement one another because their output patterns may differ, although the extent of that benefit depends on the location of generation assets and customers, weather conditions and the timing of electricity demand. Battery storage can shift some electricity from periods of higher generation to periods of greater demand, but its contribution will depend on installed capacity, charging opportunities, operating costs and grid conditions.
Diversifying supply sources could help EPIX manage differences between renewable generation and customer consumption. However, a portfolio containing multiple technologies does not by itself guarantee uninterrupted electricity supply. Businesses will still need to consider their consumption profiles, backup arrangements, network limitations and the terms of their electricity contracts.
EPIX also plans to use Energy Partners’ Syntiro platform to give customers a consolidated view of their energy systems. The platform is intended to bring together information on on-site generation, electricity consumption, wheeled power and sustainability performance, helping businesses assess operational requirements and investment options. Integrating these data streams could support decisions on energy efficiency, procurement and emissions reporting, provided the information is sufficiently accurate and comparable.
The business model also reflects a shift in how companies approach electricity procurement. Renewable energy purchasing is increasingly connected to operating costs, supply reliability and corporate emissions objectives. For energy-intensive industries such as mining and manufacturing, the ability to contract for power from different sources may provide additional flexibility. Retail, logistics and property businesses may also use renewable electricity contracts to address the energy requirements of buildings and distributed operations.
Nevertheless, the commercial outcome will depend on the details of EPIX’s supply agreements. Buyers will need to assess contracted prices, contract duration, the treatment of deviations between generation and consumption, wheeling charges, settlement arrangements and the allocation of risks when generation or network capacity is unavailable. Renewable electricity contracts may support emissions reduction objectives, but the extent of that contribution depends on the source of power and the method used to account for electricity consumption and associated emissions.
For investors, EPIX offers a route to connect renewable generation assets with commercial demand. A trading platform can help create a market for electricity from independent producers, but investment decisions still depend on the bankability of generation projects, grid connection availability, creditworthy buyers and predictable regulation. The ability to aggregate customers and match them with different generators may help develop transactions, although it does not remove project development or market risks.
The company’s longer-term ambition extends beyond South Africa. EPIX intends to expand into the Southern African Power Pool and plans to apply for the licences required to wheel electricity to customers connected across the regional network. Such an expansion would place the business within a wider cross-border electricity market, where power trading depends on national regulations, transmission capacity, interconnection arrangements and agreements between market participants.
The regional opportunity is significant in principle because electricity demand and generation resources are distributed unevenly across Southern Africa. Cross-border trading can help connect buyers with available generation, but the ability to move power between countries depends on transmission infrastructure and the rules governing regional transactions. EPIX’s expansion remains a stated intention rather than an operational regional service.
For South Africa, the launch marks another step in the development of private electricity trading and corporate renewable procurement. Its longer-term significance will depend on whether the platform can secure additional generation, convert customer demand into durable contracts and navigate the regulatory and infrastructure requirements of wheeling. As competition grows, the test will be whether new trading arrangements deliver commercially viable electricity options while supporting investment in renewable generation and the reliability of supply for businesses.
