Executive Summary
The closure of Mozal — Mozambique's largest industrial facility — on 15 March 2026 created the most significant infrastructure investment opportunity in Southern Africa in a generation. KAIROS Energy proposes to resolve it permanently.
"The Mozal smelter did not close because aluminium is not valuable. It closed because reliable, competitively-priced electricity could not be guaranteed. We are here to guarantee it — permanently, at a lower cost than any previous arrangement."
KAIROS ENERGY — Strategic ThesisThe Problem
Mozal's closure was caused by the intersection of two structural failures: a 43-year drought low on the Zambezi basin that collapsed HCB's hydroelectric output by 30.7%, and a failure to negotiate a commercially viable energy tariff for the post-2026 period.
The result is a facility representing 3.9% of Mozambique's GDP, 25,000 direct and indirect jobs, and $372M in South32 write-downs, sitting idle — awaiting an energy solution that no existing player has the mandate or the capital structure to deliver.
The Solution
KAIROS Energy proposes the development of a 3,650 MWp solar photovoltaic facility with 10,800 MWh of battery energy storage, supported by 280 MW of gas-fired backup capacity — structured as a phased Independent Power Producer (IPP) delivering 950 MW to the Mozal smelter under a 20-year take-or-pay Power Purchase Agreement.
The project delivers electricity at a Levelised Cost of Energy of approximately 4.6¢/kWh — materially below the tariff that caused Mozal's closure, and below any competing generation source in the region.
The Opportunity
Five converging factors create a window of opportunity that is simultaneously time-limited and structurally unique. Each factor alone is significant. Together, they define a once-in-a-generation infrastructure play.
South32 has not written off Mozal — it placed it in "care and maintenance" at $5M/year. The CEO explicitly stated reactivation is possible "when conditions change." South32 is a creditworthy, ASX-listed counterparty. A signed PPA with South32 is the single most valuable document in this entire project structure.
Mozal represented 3.9% of Mozambique's GDP and 40% of Maputo province's industrial output. Every day it remains closed is a political liability for the government. The operator who presents a credible reopening plan receives a level of regulatory facilitation and tax incentive access that is unprecedented in normal market conditions.
Utility-scale LFP battery systems have reached $125/kWh all-in — a 43% reduction from 2023. Sodium-ion chemistry (2027+) will push this to $60–80/kWh. The project's LCOE of 4.6¢/kWh is achievable today. This number was not achievable two years ago and demonstrates why no previous attempt succeeded.
MOTRACO's twin 400kV transmission lines run from the South African grid through Eswatini and Namaacha directly to Beluluane — passing through Boane District, the proposed solar farm location. No new long-distance transmission is required. The site connects to existing grid infrastructure that was built specifically to serve Mozal.
23 years of NASA POWER data (2000–2023) for Beluluane (-25.92°S, 32.41°E) shows a daily average GHI of 5.62 kWh/m²/day, annual total of 2,050 kWh/m²/year, with the P99 worst-day scenario at 2.5 kWh/m²/day — used to size BESS conservatively. The site ranks in the top quartile globally for utility-scale solar resource quality.
Stakeholder Map
Six principal stakeholders must be engaged, sequenced correctly, and aligned to their respective interests. Understanding what each party needs — not what they say they want — is the negotiation foundation.
Technical Solution
A hybrid generation architecture combining large-scale solar photovoltaics, grid-scale battery storage, and gas-fired backup — optimised for the specific load profile of an aluminium smelter operating 24/7 at near-constant draw.
Solar Resource — Beluluane Station
Space Optimisation Strategy
LONGi Hi-MO9 / JinkoSolar Tiger Neo · 730–780 Wp/panel · N-type bifacial · 23–24% efficiency · Fewer components per MW → lower BoS cost and reduced maintenance footprint.
Panels elevated 2–3m · White gravel albedo surface (0.55–0.65) · Bifacial rear gain +10–12% · Flood protection · Maintenance access · Net area reduction ~10%.
Selective use of vertical bifacial E-W configuration in sub-zones · Two generation peaks (morning/afternoon) flattens load curve → reduces BESS sizing → area reduction ~30% in those zones.
Site & Transmission
The project benefits from a pre-existing 400kV transmission corridor that runs directly through the proposed solar farm site — a coincidence of geography and infrastructure that materially de-risks and accelerates the project.

Transmission Infrastructure
Twin 400kV lines running Camden (SA) → Eswatini → Namaacha → Boane → Beluluane/Mozal. 565 km total. Pass directly through proposed solar farm site. Connection requires lateral spur only — not a new long-distance line.
Recently completed EDM substation in Boane/Mahoche. Fully digitalised, fibre-connected, linked to EDM's future National Control Centre. Secondary injection point for surplus energy sales.
AfDB-financed 66kV line linking Namaacha wind corridor to Boane. Passes through the project's western boundary. Additional injection capacity available from 2026.
In most comparable projects in Africa, transmission infrastructure represents 15–25% of total CAPEX and 2–4 years of additional development time. This project eliminates both. The MOTRACO corridor runs directly through the solar farm site — the connection is a short lateral, not a national infrastructure programme. This is the single most significant de-risking factor in the entire project.

World Bank Group Strategy
The World Bank Group is not simply a lender. It is a validator, a risk insurer, a process accelerator, and a co-investor — simultaneously. The engagement strategy must leverage all five arms of the Group in the correct sequence.
Primary debt financier. Has financed a 1GW solar + 600MWh BESS project in Egypt in 2025 — direct precedent. Operates the Scaling Solar programme specifically for sub-Saharan Africa with standardised bankable documents.
Entry Point: IFC Advisory ServicesEngage advisory first — they help structure the project for bankability before lending. No cost, enormous value.
Political risk insurance — expropriation, war, currency inconvertibility. Already has a precedent with MOTRACO (1999 guarantee). With MIGA coverage, commercial lenders can participate at investment-grade pricing.
Entry Point: Online Application + Meeting RequestMIGA's Mozambique team is accessible. Reference the MOTRACO precedent explicitly.
Provides Partial Risk Guarantees — guarantees that the Mozambique government will honour its contractual obligations. If the government fails to comply with the GSA, IDA pays. Removes sovereign non-performance risk.
Entry Point: World Bank Country Office MaputoWorld Bank is already financing TREP in Mozambique. Existing relationships in-country.
Concessional finance at 0.25% for projects reducing GHG emissions at scale. A 950 MW solar + storage project in Mozambique is exactly the profile. $300–500M of CTF financing can reduce blended WACC by 1.5–2 percentage points.
Entry Point: National Designated Authority (Mozambique)Government of Mozambique is the CTF access point. Requires government champion.
IFC's equity co-investment arm. Manages funds that can take direct equity positions in SPVs. If IFC AMC takes 10–15% equity, it brings additional catalytic effect and signals to the market that the project has passed IFC's internal due diligence.
Entry Point: After IFC debt mandate confirmedEquity discussions follow debt structuring — sequence matters.
Lends directly to the Government of Mozambique to finance EDM's participation, grid strengthening, and the government's equity contribution to the SPV. The TREP project ($500M, 400kV Vilanculos-Maputo) shows the Bank is already deeply engaged in Mozambique's transmission.
Entry Point: World Bank Maputo OfficeLeverage TREP relationships. Same teams, same mandate, adjacent project.
"The Scaling Solar programme was designed precisely to eliminate the barriers that historically prevented projects like this from reaching financial close in sub-Saharan Africa — standardised documents, pre-approved financing terms, political risk coverage. It is the fastest path from concept to bankable project in the region."
IFC Scaling Solar Programme — Strategic OverviewMOTRACO Strategy
MOTRACO is simultaneously the project's most critical infrastructure partner and its most compelling strategic acquisition target. The two objectives must be sequenced carefully — partnership first, ownership second.
Phase A — Wheeling Agreement (immediate)
The first objective is to negotiate a long-term wheeling agreement — the right to transmit the project's solar energy through MOTRACO's existing 400kV infrastructure to the Mozal substation at a commercially agreed tariff.
Phase B — Equity Acquisition (M+12 to M+24)
The strategic objective — acquiring Eskom's one-third stake in MOTRACO — must be pursued after the PPA and IPP licence are secured, but before Phase 1 commissioning. Eskom's motivation to sell is structural.
Eskom is in chronic financial distress. Their MOTRACO stake — once a revenue-generating asset tied to Mozal — is now near-worthless with Mozal closed.
The KAIROS solar project replaces Eskom as energy source for Mozal — eliminating their supply obligation AND their future MOTRACO revenue simultaneously.
A cash offer for Eskom's MOTRACO stake, framed as a "clean exit" from their Mozambique obligations, is highly likely to find receptivity at the right price.
+ Transmission
Whoever controls both power generation and transmission in a regional energy corridor becomes, for all practical purposes, the energy sovereign of that corridor. KAIROS Energy, owning the solar generation asset and a stake in MOTRACO's transmission infrastructure, would be in that position — with a 25-year PPA providing the revenue base, and MOTRACO's 565km regional network providing the distribution platform for future expansion into Eswatini, Zimbabwe, and eventually Tanzania.
Risk Matrix
All material project risks are identified, assessed, and assigned specific mitigation strategies. The project's risk profile is materially lower than comparable greenfield IPPs in the region due to the pre-existing infrastructure, creditworthy offtaker, and institutional support structure.

Development Sequence
The next 90 days are the most critical period in the project's life. The window to secure preferential terms — with South32, with the Government, and with financiers — is open now and will not remain open indefinitely.
The Government of Mozambique has stated publicly that it estimates Mozal could resume within 12 months. That clock started on 15 March 2026 — today. The HCB reservoir will eventually recover. South32's patience for care-and-maintenance costs is not unlimited. The political urgency that today gives KAIROS Energy maximum negotiating leverage will diminish as months pass and other options are explored.
The development sequence above is achievable within 10 months to financial close. The question is not whether this project is viable — the economics, the resource, the infrastructure corridor, and the institutional appetite all confirm it is. The question is whether the development phase is initiated with the urgency that the window demands.
