- Virtual wheeling empowers SMEs by providing them with direct access to clean, affordable, and reliable energy, without requiring long-term financial commitments.
- Affordable renewable energy boosts competitiveness, improves cash flow, and drives sustainable growth within South Africa’s SME sector.
South Africa’s renewable energy landscape is undergoing rapid change. Renewable energy is no longer just a backup to Eskom’s unstable grid. It now stands as a central pillar of the nation’s power mix.
This shift presents small and medium-sized enterprises (SMEs) with a valuable opportunity to access affordable, cleaner, and more reliable electricity. It also helps them reduce running costs without heavy investment in physical infrastructure.
Over the past 18 months, several policy reforms have reshaped the energy market. These changes have opened doors to private generation, traditional wheeling, and, most importantly, virtual wheeling. This model enables businesses to use renewable energy generated off-site.
Through a system of rebates, companies can match the electricity they draw from the grid with clean power supplied by independent power producers (IPPs). As a result, Eskom’s framework simplifies access for corporates and municipalities, making renewable energy more inclusive and efficient.
Vodacom and the Sola Group pioneered one of the first virtual wheeling partnerships in Africa. They launched their power purchase agreement (PPA) in September 2025, setting a bold precedent for others to follow. This milestone gave SMEs the confidence to participate in South Africa’s renewable revolution.
Unlike traditional PPAs that lock businesses into 20-year contracts, virtual wheeling offers shorter and more flexible agreements. This structure suits smaller firms that prefer low-risk commitments. SMEs can now buy renewable power without installing costly solar panels or wind turbines. Additionally, independent producers are offering rolling contracts that deliver immediate operational savings, thereby further lowering entry barriers.
Flexibility is expected to increase even further with the launch of the South African Wholesale Electricity Market (SAWEM) in 2026. The new platform will allow licensed participants to trade electricity as a commodity. This step will boost competition and transparency. Consequently, SMEs will be able to compare offers, choose renewable suppliers, and manage energy costs more predictably.
Meanwhile, advances in battery energy storage systems (BESS) are transforming the way renewable power is stored and utilised. According to BloombergNEF, global battery prices have dropped to about $115 per kWh. This reduction makes storage more affordable for developers. As a result, solar and wind energy can now be stored efficiently and delivered on demand. Renewable power can therefore provide a continuous, 24-hour supply, rather than fluctuating with weather conditions.
However, South Africa still faces infrastructure challenges. The national transmission grid is reaching capacity in renewable-rich regions such as the Northern Cape. This pressure has prompted fresh investment to expand and modernise the grid, ensuring future stability and reliability.
Ultimately, the country’s focus is shifting from load-shedding to self-reliance. Clean and flexible energy now provides a strong competitive advantage. It shields businesses from price volatility, supports exports, and aligns with national sustainability goals.
SMEs, which employ nearly 60% of South Africa’s workforce, now have a genuine chance to join the clean energy transition. Virtual wheeling levels the playing field by granting smaller firms the exact cost and sustainability benefits enjoyed by large corporations. This inclusive shift strengthens industries, empowers communities, and fuels economic growth.
In the long run, virtual wheeling will do more than lower energy costs. It will reinforce South Africa’s position as a leader in clean energy innovation. With accessibility, affordability, and flexibility combined, the country is moving decisively towards a more resilient and sustainable energy future.
