Market & Industry Analysis
The South African and SADC power deficit, the REIPPPP and bid-window dynamics, the corporate-PPA market and the market sizing underpinning Kalahari Grid.
3.1 The South African power market
South Africa faces a structural electricity deficit. Decades of
underinvestment and an ageing, unreliable coal fleet have produced
sustained load-shedding, and the Integrated Resource Plan envisions tens
of gigawatts of new renewable capacity over the coming decade.
Renewables are now the cheapest new-build option: utility-scale solar
cleared Bid Window 7 at around R0.60/kWh, below new-build coal, and the
country’s exceptional solar resource (Northern Cape irradiation above
2,800 kWh/m²) and strong wind resource make it one of the most
attractive renewable markets globally. The demand for new capacity is
not in question; the constraints are structural and sit downstream of
demand.
3.2 REIPPPP and the procurement landscape
The Renewable Energy IPP Procurement Programme (REIPPPP) is the
flagship route to market: over R256 billion of private investment and
more than 7,300 MW awarded across successive windows since 2011, under
standardised, government-backed 20-year PPAs. Projects must reach
commercial operation within 24 months of commercial close. Alongside
REIPPPP sit the Battery Energy Storage IPPPP (615 MW awarded in Bid
Window 2 across eight substation sites) and, from 2025, the Independent
Transmission Projects programme — the first private procurement of
transmission infrastructure, a direct response to the grid constraint.
Bid Window 8 opened for 3 GW with a 4-hour storage mandate on 40% of
capacity and raised local-content thresholds, signalling the market’s
direction: firmer, storage-integrated, higher-local-content
renewables.
capacity
The single most important fact for this business is that grid
connection, not capital or demand, limits new build. In Bid Window 7,
solar PV received 8.5 GW of bids against an 1.8 GW allocation — 4.7x
oversubscribed — while onshore wind, allocated 3.2 GW, was awarded
nothing across two consecutive windows because grid capacity in the
high-wind Cape provinces was already taken and bid tariffs were judged
uncompetitive. Eskom’s network needs roughly R100 billion of upgrades,
and industry reporting suggests 60–70% of prospective projects face
curtailment or multi-year connection queues, with mid-day solar
saturating the Northern Cape-to-Gauteng corridor and cutting output by
as much as 20%. Any 5 GW ambition must be underwritten by a credible,
project-by-project grid-access strategy — which is why grid applications
sit on the critical path in Section 5 and grid risk is the top-ranked
risk in Section 10.
3.3 Tariffs and the offtake mix
Tariff realisation is the second decisive variable. REIPPPP
utility-scale solar now clears around R0.60/kWh (roughly $0.033/kWh) —
highly competitive, but thin for servicing high project-finance gearing.
Corporate PPAs and wheeled power to mining and industrial offtakers
command materially higher effective tariffs (often $0.06–0.08/kWh,
USD-linked), reflecting the premium large users place on reliability and
price certainty against Eskom’s escalating and time-of-use tariffs,
which reach far higher at peak. The blended $0.055/kWh assumed in the
sponsor case therefore implies a mix weighted toward corporate and
wheeled offtake, not pure REIPPPP solar — and, as Section 7 shows, the
achievable blended tariff is the pivotal determinant of bankability and
returns.
3.4 Market sizing and the corporate-PPA opportunity
The addressable market is large and expanding. South Africa’s
installed solar base alone is forecast to roughly double from around 8
GW in 2025 toward 14–17 GW by 2030–2031, and the Integrated Resource
Plan contemplates far more renewable and storage capacity than has been
procured to date. Beyond REIPPPP, the corporate PPA and wheeling market
has emerged as the primary driver of new build: mining majors,
data-centre operators and industrials are contracting directly with IPPs
— recent examples include multi-hundred-megawatt solar PPAs with mining
and data-centre offtakers, several incorporating wheeling through
municipal networks. This private market is where premium tariffs and
faster execution live, and it is central to the Company’s revenue
strategy.
For a developer-IPP, the serviceable opportunity is defined less by
total market size than by two scarce resources: grid-connection capacity
and creditworthy offtakers willing to pay a premium for firm, clean
power. The Company’s strategy — securing grid corridors early and
originating corporate PPAs alongside REIPPPP bids — is explicitly
designed to capture both. The 5 GW target represents a small share of
the national build-out the IRP envisions, so the constraint on the
Company is execution and grid access, not market headroom.
3.6 Grid connection: process, corridors and the ITP response
Connecting a utility-scale project to the grid runs through the
National Transmission Company South Africa (NTCSA): a cost-estimate
letter, then a budget quote, then a signed connection/grid agreement
reserving capacity — each stage gating the next and, for REIPPPP,
required ahead of bidding. 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.
| Corridor / region | Resource | Grid status | Company approach |
|---|---|---|---|
| Northern Cape (Upington/Kimberley) | Exceptional solar | Saturated; curtailment risk | Selective; storage-firmed; existing reservations only |
| Free State | Good solar; some wind | Emerging headroom | Priority Phase 2 corridor |
| Eastern Cape | Strong wind | Constrained (wind-heavy) | Wind + corporate offtake; ITP-dependent |
| Limpopo | Solar; wind pockets | Transmission upgrades needed | Anchor wind corridor; transmission-linked |
| Mpumalanga (just transition) | Solar | Coal-grid capacity freeing up | Repurpose retiring-coal grid connections |
The Independent Transmission Projects (ITP) programme, launched in
2025 as the first private procurement of transmission in South Africa,
is the structural response to this constraint — and a development
opportunity. Where economic, the Company will participate in or
co-develop transmission to unlock its own generation corridors,
converting the binding constraint into a differentiated capability.
Co-located storage (aligned to the Bid Window 8 four-hour-storage
mandate on 40% of capacity) further eases connection by firming output
and reducing curtailment.
3.7 Regional expansion — the SADC opportunity (Phase 3)
Phase 3 extends the platform into Zambia, Namibia and Botswana, where
the same structural deficit that defines South Africa is more acute and
renewable penetration is lower. Zambia’s hydro-dependent grid has been
severely stressed by drought, forcing extended load-shedding and
creating urgent demand for solar and storage — particularly for
Copperbelt mining loads, the anchor for the Company’s BESS hub concept.
Namibia and Botswana combine exceptional solar resource with small,
import-dependent grids and active renewable-procurement agendas.
| Market | Opportunity | Entry approach |
|---|---|---|
| Zambia | Drought-stressed hydro grid; Copperbelt mining demand; solar + storage | BESS hub for mining peak-shaving; C&I solar PPAs |
| Namibia | World-class solar/wind; import-dependent; active procurement | Utility & C&I PPAs; possible export to SA/SAPP |
| Botswana | Strong solar; coal-reliant; diversification agenda | Utility-scale solar; regional interconnection |
Regional expansion is deliberately sequenced last: it carries higher
political, currency and grid-interconnection risk, and is underwritten
only once the South African platform is operational and cash-generative.
DFI political-risk cover, local partnerships and the Southern African
Power Pool’s interconnection framework are the principal mitigants. The
regional pipeline offers optionality and growth beyond the core 5 GW,
rather than being a precondition for the base-case returns.
