Market & Industry Analysis
The Southern African power deficit and energy-transition market, the regional demand drivers, the trading opportunity and the market sizing underpinning Helios Nexus.
3.1 The South African electricity market
South Africa consumes over 200 TWh of electricity annually, making it
the largest and most industrialised power market on the continent.
Decades of underinvestment and an ageing, unreliable coal fleet have
produced sustained load-shedding and a structural supply deficit, while
the Integrated Resource Plan envisages tens of gigawatts of new
renewable and storage capacity over the coming decade. Renewables are
now the cheapest new-build option, and the country’s exceptional solar
and wind resources make it one of the most attractive renewable markets
globally. Demand is anchored by energy-intensive sectors — mining,
manufacturing, commercial property — and by two of the fastest-growing
loads, data centres and telecommunications.
3.2 Demand drivers and target segments
The Company targets a contracted demand base of roughly 12 TWh across
five segments, anchored by the mining sector’s need for reliable,
decarbonised, cost-competitive power over long horizons.
| Segment | Target demand | Rationale |
|---|---|---|
| Mining (copper, PGM, gold, coal, manganese) | 5 TWh | Energy-intensive; decarbonisation and cost pressure; long-life offtake |
| Industrial manufacturers (steel, cement, chemicals, food) | 3 TWh | Process-heat and power; carbon-border and cost drivers |
| Data centres | 2 TWh | Fastest-growing load; hyperscale renewable mandates |
| Property groups (malls, logistics, offices) | 1 TWh | Wheeling-suited multi-site portfolios |
| Government & municipal infrastructure | 1 TWh | Strategic and public-sector demand |
constraint
As across the whole South African renewable sector, grid-connection
capacity — not demand or capital — is the primary limit on new build.
Connection in the highest-resource regions (the Northern Cape solar
corridor, the Eastern and Western Cape wind corridors) is largely spoken
for, connection studies and agreements can take many months to years,
and curtailment risk is rising as corridors saturate. Eskom’s
transmission network requires major upgrades, and the new Independent
Transmission Projects programme is the structural response. Any 6 GW
generation ambition must therefore be underwritten by a credible,
project-by-project grid-access strategy — which is why grid applications
sit on the critical path in Section 9 and grid risk is the top-ranked
risk in Section 11.
3.3 The trading and wheeling opportunity — and its regulatory frontier
The most distinctive and fastest-evolving part of the market is
electricity trading and wheeling. The 2021–2023 ERA reforms enabled IPPs
to wheel power across the Eskom and municipal grids to multiple
offtakers, and a cohort of traders and aggregators — Envusa Energy
(Anglo American/EDF), NOA Group (Old Mutual), the Energy Exchange of
Southern Africa (Remgro), Etana Energy, Enpower, PowerX and Africa
GreenCo — has emerged to intermediate between generators and corporate
buyers. In June 2025 Eskom launched its Virtual Wheeling Platform (VWP),
a digital mechanism that aggregates time-of-use generation and
consumption data and refunds a single buyer, dramatically simplifying
multi-site wheeling and, in the pilot with Vodacom, proving the model
across 15,000+ sites and 168 municipalities.
frontier is a live risk
The trading and wheeling opportunity is real and large, but its
regulatory framework is still being written, and this is a genuine risk
to the division that contributes 15% of the platform’s revenue. NERSA
published notice in July 2025 of its intention to develop formal
electricity Trading Rules under section 35 of the ERA, with gazetting
anticipated around mid-2026. Critically, when Eskom launched the VWP it
initially excluded third-party traders pending those rules — a decision
publicly criticised as anti-competitive and still unresolved at the time
of writing. Municipal wheeling frameworks remain patchy (SALGA has
reported only a few operational municipal wheeling systems), and virtual
PPAs are not yet available in South Africa. The Company’s trading and
wheeling revenue therefore depends on regulatory outcomes partly outside
its control. The Plan mitigates this by anchoring the platform in owned
generation (70% of revenue) rather than pure trading, sequencing the
trading licence and VWP onboarding early, and treating trading/wheeling
as margin-accretive optionality on top of a contracted generation base —
not as the foundation of the investment case.
The prize is nonetheless substantial: as a licensed trader and VWP
participant, Helios Nexus can aggregate its own and third-party
generation, serve smaller and multi-site offtakers that cannot contract
directly with a single IPP, and capture a margin on volume that a pure
generator cannot. This is the value layer that differentiates the
platform from a traditional IPP, and the Company’s strategy is to secure
a NERSA trading licence and VWP certification as the framework
crystallises.
3.4 Grid connection, corridors and the transmission response
Connecting utility-scale generation to the grid runs through the
National Transmission Company of South Africa (NTCSA): a cost-estimate
letter, a budget quote, then a connection agreement reserving capacity.
Capacity is allocated at the substation and corridor level, and in the
highest-resource regions it is largely spoken for — which is why award
geography has shifted and why early, project-by-project grid
applications are the Company’s first development action across every
generation project.
| Corridor / region | Resource | Grid status | Helios approach |
|---|---|---|---|
| Northern Cape | Exceptional solar | Saturated; curtailment risk | Selective; storage-firmed; secured reservations |
| Free State / North West | Good solar | Emerging headroom | Priority solar corridors (Solaris) |
| Eastern Cape | Strong wind | Wind-constrained | Wind + storage + corporate offtake (Zephyr) |
| Western Cape | Strong wind | Constrained | Wind; wheeling to metro offtakers |
| Regional (SADC) | Solar/hydro/wind | Under-developed | Phase-4 expansion (Infinity) |
The Independent Transmission Projects (ITP) programme, launched in
2025 as the first private procurement of transmission in South Africa,
is the structural response to the grid constraint — and a development
opportunity. Co-located storage further eases connection by firming
output and reducing curtailment, aligning the generation and storage
divisions with grid-access strategy. The Company’s grid-first site
selection — choosing sites for connection availability first, resource
quality second — is the same inversion the market’s own award data now
reflects.
3.5 Market structure, reform and the regional opportunity
South Africa’s electricity market is undergoing the most significant
structural reform in its history. The Electricity Regulation Amendment
Act, signed in 2024, establishes a competitive multi-market structure
with an independent transmission system operator, opening the path from
a vertically-integrated Eskom monopoly to a liberalised market with
independent generators, traders and a wholesale exchange. This is the
macro backdrop that makes an integrated platform strategy possible — and
timely.
| Reform milestone | Status | Implication for Helios Nexus |
|---|---|---|
| Licensing threshold removed (2021–22) | In force | Generation projects proceed without NERSA licensing delay |
| Multi-offtaker wheeling enabled (2023) | In force | Wheeling to multiple corporate customers |
| NTCSA established (2024) | Operational | Independent transmission; ITP programme |
| ERA Amendment Act (2024) | Enacted; phasing in | Competitive market; wholesale trading; exchange |
| NERSA Trading Rules (s35) | Anticipated ~mid-2026 | Formalises trading licences and market access |
| Eskom VWP | Live (June 2025) | Multi-site virtual wheeling; trader access pending |
Beyond South Africa, the regional opportunity is substantial. The
Southern African Development Community faces acute power deficits, and
the Southern African Power Pool provides a mechanism for cross-border
trade. Zambia (copper-mining demand and drought-impaired hydro),
Botswana, Namibia (green-hydrogen ambitions), Mozambique (gas and hydro)
and Zimbabwe all present generation and trading opportunities that
Project Infinity targets in Years 7–10. Regional expansion diversifies
country risk and positions the platform to trade across the SAPP as
regional market integration deepens — the long-dated optionality
embedded in the platform strategy.
