Eskom has recently awarded a major contract to Johannesburg-based Enerweb to develop a sophisticated software platform designed to automate and expand its virtual wheeling service, marking a pivotal advancement in the utility’s efforts to modernise electricity distribution.
As reported by Moneyweb, this appointment represents the most significant progress to date in operationalising virtual wheeling, a mechanism crucial for enabling independent power producers to supply renewable energy to smaller, low-voltage consumers across Eskom’s network or within compliant municipal areas. Unlike conventional wheeling, which has primarily served large industrial clients through direct, long-term agreements, the virtual approach aims to democratise access for thousands of commercial and manufacturing entities via shorter contracts.

The South African renewable energy market is poised for substantial growth, with installed capacity estimated at around 16.31 gigawatts in 2025 and projected to reach 28.30 gigawatts by 2030, expanding at a compound annual growth rate of 11.65 per cent, according to Mordor Intelligence. This expansion reflects the pressing need for efficient integration of new green sources amid persistent supply challenges that have historically constrained economic output.
However, the initiative is unfolding amid ongoing regulatory disputes and legal challenges that underscore tensions in the evolving electricity trading landscape. A successful proof-of-concept involving a leading telecommunications firm highlighted technical feasibility but also the inefficiencies of manual processes for managing diverse generators, buyers, and intricate settlements.
As outlined by the National Energy Regulator of South Africa (Nersa), recently published draft trading rules—now under stakeholder consultation with hearings planned for January 2026 and finalisation anticipated by early that year—aim to clarify trader conduct, settlement procedures, and data flows, paving the way for their inclusion in virtual wheeling schemes. These rules are essential for broadening market participation beyond large corporates.
The Enerweb platform will integrate generation, usage, and billing information into a single system, automate rebate calculations, embed them into existing invoicing, ensure robust audit trails, and offer intuitive portals for users, including eventual support for traders. It is engineered to process detailed, time-of-use metering data from standards-compliant devices, accommodating the country’s patchwork of distribution networks where municipal involvement varies widely, compounded by a sharp rise in arrears owed to Eskom.
Critics have raised concerns over Eskom’s legal actions contesting certain trading licences, viewing them as efforts to preserve dominance rather than foster the competitive environment outlined in national reform policies. Nonetheless, the parallel advancement of digital infrastructure alongside regulatory progress indicates a strategic push to align with ambitious 2026 milestones, including the launch of a transitional wholesale market, while addressing municipal revenue sensitivities through a rebate model that temporarily sidesteps direct impacts.
In the longer term, virtual wheeling positions itself as a vital interim solution, facilitating access to private renewables despite infrastructure limitations and laying groundwork for trader-driven, portfolio-style procurement. With projections suggesting renewables could account for a growing share of capacity additions through 2030, as highlighted in GreenCape analyses of large-scale opportunities, this automated platform may emerge as a cornerstone in South Africa’s shift towards a more resilient and competitive energy framework.
