For a century, South Africa’s electricity was a monolithic affair: Eskom made the power, moved the power, and sent the bill. But as the state utility’s grip loosens, a new class of “energy middle-men” is racing to capture a market that hasn’t existed until now.

With the South African Wholesale Electricity Market (SAWEM) scheduled to launch in April 2026, the regulatory floodgates have opened. The National Energy Regulator of South Africa (NERSA) has already issued licenses to over 14 private energy trading firms, ranging from legacy banks to fintech giants. Venture-backed startups are also positioning in the growing value chain. 

The prize? The ability to buy electrons from private wind and solar farms and sell them directly to factories, mines, and debt-laden municipalities.

The New Market Map: From Miners to Municipalities

The competition is no longer just about building wind farms; it is about who owns the contracts and the data between the turbine and the light switch.

1. The Power Aggregators: Building “Virtual Utilities”

The most aggressive players are the aggregators, who buy energy from multiple sources to create a “blended” supply that is more reliable than a single solar farm.

• NOA Group: Backed by R3.9 billion from Old Mutual’s AIIM, NOA combines its own 600 MW “generation fleet” with third-party supply. Their focus is on high-volume industrial clients, recently securing a landmark wheeling deal with Netcare.
• Discovery Green: Leveraging its actuarial roots, the Discovery Limited subsidiary uses its “Green Node” system to offer businesses up to 90% renewable penetration. They have already locked in massive corporate offtakers like Glencore, Sasol, and Implats.
• Green Electron Market (GEM): Owned by Sturdee Energy, GEM is carving out a niche in the coal-heavy industrial heartland of Mpumalanga. Their strategy is regional dominance, specifically targeting mining operations like Evander Gold.

2. The Last-Mile Fintech Play: BluEnergy

While aggregators focus on big industry, BluEnergy Trading — a subsidiary of JSE-listed Blue Label Telecoms — is targeting the most difficult segment: municipalities.

Licensed in February 2026, BluEnergy’s advantage isn’t just energy; it’s revenue collection. Through its partner Cigicell, the company is already embedded in 95+ municipalities for prepaid electricity vending. By combining energy trading with proven prepaid infrastructure, they solve the “payment risk” that has historically kept private investors away from municipal grids.

3. The Digital Plumbing: Open Access Energy (OAE)

Trading electricity in a liberalizing market requires more than just a license; it requires a real-time clearinghouse. Last year, Cape Town-based Open Access Energy raised $1.8 million in seed funding to provide the software layer backed by pan-African climate tech investors E3 Capital and Equator, with participation from Factor[e] Ventures. Their EnergyPro platform uses AI to automate “wheeling” — the complex process of routing power across multi-owner grids and handling the financial settlement between producers and traders.

The 2026 “Big Bang”

The launch of SAWEM in April 2026 represents the most significant structural change to the South African economy in decades. It shifts the country from a single-buyer model toward a “multi-buyer, multi-seller” framework.

The transition hasn’t been seamless. Eskom initially launched legal challenges against NERSA’s trading licenses, citing concerns over “cherry-picking” — where private traders take the best-paying customers, leaving the state utility with the debt-burdened poor.

However, political pressure has mounted. Electricity Minister Kgosientsho Ramokgopa has publicly urged Eskom to drop these challenges to avoid stalling the R4.7 billion battery storage and renewable pipeline. By early 2026, the consensus among analysts is that the market is now “irreversible.”

The Bottom Line

The “Chase” is no longer about who can build the biggest power plant. It is about who can manage the complexity of the trade. As the April 2026 deadline looms, the winners will be those who can solve the two biggest hurdles in South African energy: grid access and payment assurance.

For the first time, South African businesses and municipalities are no longer just “customers” — they are “shoppers” in a competitive market.
