A Record-Breaking Memorandum
The corridors of Gaborone’s Ministry of Minerals and Energy seldom witness signatures of the magnitude affixed on 6 November. By committing 5.5 billion US dollars over seven years, the Government of Botswana and Turkey’s Ulsan Holding endorsed what officials describe as the largest single private-public energy partnership in the country’s history (Botswana Ministry of Minerals and Energy, 7 November). Sitting beside Minister Bogolo Joy Kenewendo, Ulsan president Fatih Gülsün declared that the accord “cements Botswana’s rise as a reliable power hub in Southern Africa”.
The memorandum, co-signed by executives from Mercuria Energy Trading, IGI and Tfgl, spans rehabilitation of the ageing Morupule A and B coal plants, construction of photovoltaic parks and deployment of clean-coal technologies. Its ambition defies the binary view that coal and climate goals are incompatible: the parties insist that advanced carbon-capture systems and high-efficiency boilers will align with Botswana’s updated Nationally Determined Contribution under the Paris Agreement.
Rehabilitating Morupule: Coal in a New Light
Morupule, situated near Palapye, supplies about 60 percent of Botswana’s electricity yet has grappled with unplanned outages and escalating maintenance costs. The programme foresees retrofitting Unit 1-4 turbines, installing flue-gas desulphurisation and digitising control rooms. Engineers expect the upgrade to reclaim 600 MW of dependable baseload, a critical buffer for a grid that still imports seasonal power from South Africa’s Eskom.
Technologists argue that modernising existing coal stations avoids the emissions spike associated with greenfield construction. By elevating thermal efficiency from the current 32 percent to an estimated 40 percent, the project could abate more than a million tonnes of CO₂ annually compared with business as usual, according to preliminary modelling shared by the Botswana Institute for Technology Research and Innovation.
Solar Ambitions Beneath the Kalahari Sun
Complementing coal retrofits, Ulsan and its partners will finance 900 MW of utility-scale solar arrays, with sites shortlisted in the semi-arid Kgalagadi and Central districts where insolation exceeds 2 200 kWh/m² per year. The photovoltaic component is scheduled to reach financial close by mid-2024 and full commissioning by 2027.
Grid-integration studies led by the Southern African Power Pool (SAPP) Secretariat underscore the need for new transmission corridors from the solar parks to the Morupule load centre. The accord therefore earmarks funds for 400-kV lines and digital substations, a move applauded by regional planners keen to alleviate the congested north-south spine that currently restricts cross-border trade.
Trading Power Through the Southern African Pool
Botswana’s electricity demand plateaued at roughly 800 MW in 2022, a modest figure compared with the 1.5 GW envisaged under the agreement. Surplus capacity is thus destined for export. SAPP’s day-ahead market has already registered a tenfold increase in traded volumes since 2017, and Minister Kenewendo notes that “a reliable Botswanan supply can further stabilise prices for landlocked neighbours such as Namibia and Zimbabwe.”
Market analysts at Standard Bank posit that revenues from power exports could offset nearly a third of Botswana’s capital expenditure over the life of the assets, assuming conservative tariffs of 5 US cents per kWh. Such projections have bolstered the government’s sovereign credit narrative at a juncture when mineral receipts, particularly from diamonds, confront cyclical headwinds.
Congo-Brazzaville: Ulsan’s Parallel Bets
While cameras flashed in Gaborone, Ulsan’s engineers were simultaneously inspecting rail sleepers on the 465-kilometre Mayoko–Pointe-Noire line in the Republic of Congo. The Turkish conglomerate’s mining subsidiary plans to launch a three-million-tonne-per-annum iron ore operation in 2026, rising to five million tonnes by year three. Successful ore evacuation hinges on rehabilitating the colonial-era track now operated by the Albayrak Group, a task Ulsan views as “essential regional infrastructure” rather than a mere logistics add-on.
Discussions with Brazzaville authorities have also progressed toward allocating a plot in a special industrial zone for an integrated complex producing iron pellets, direct-reduced iron and finished steel. A captive 120-MW clean-energy facility—drawing on waste-heat recovery and possible solar hybrids—would supply the plant. Government officials emphasise that the project dovetails with Congo’s strategy to monetise its mineral endowment domestically, creating industrial jobs while respecting President Denis Sassou Nguesso’s climate commitments.
Financing Structure and Industrial Spin-offs
The 5.5 billion-dollar envelope is expected to blend export-credit guarantees from Turkish and Asian agencies, a debt tranche syndicated by African commercial banks and a minority equity injection from Botswana’s sovereign wealth fund. Mercuria Energy Trading, acting as offtaker for a share of coal and power, underpins revenue visibility, while IGI’s experience in multilateral negotiations mitigates political-risk perceptions.
By sequencing investments—first in rehabilitation, then in new build—the consortium anticipates earlier cash flow and lower balance-sheet stress. Economists at the University of Botswana calculate that local procurement could exceed 30 percent of total spend, catalysing a domestic supply chain for transformers, steel structures and civil works. Vocational institutes are already drafting curricula for welders and solar technicians, illustrating the agreement’s social ripple effects.
Balancing Transition: Clean Coal Versus Decarbonisation
Critics have questioned whether deploying capital to coal, even so-called ‘clean coal’, is compatible with Africa’s leapfrogging narrative. Yet proponents counter that the continent emits barely three percent of global greenhouse gases and must ensure energy security before contemplating deep decarbonisation. International Energy Agency scenarios indicate that, under a sustainable development pathway, sub-Saharan coal capacity can decline after 2030 provided renewables and gas mature sufficiently.
Minister Kenewendo, speaking to regional press, insisted that the partnership with Ulsan “does not lock Botswana into a high-carbon future; it buys us time and resilience.” Her stance finds echo in Congo-Brazzaville, where the emphasis is on vertical integration and value addition as prerequisites for a credible green transition. In both theatres, Ulsan portrays itself as an industrial catalyst rather than a fossil-fuel holdout, pointing to its growing portfolio of solar, battery storage and advanced-material research.
Ultimately, the accord’s success will be measured not merely in megawatts but in governance, skills transfer and the ability of Southern African economies to navigate the complex path between electrification imperatives and climate stewardship. For now, the signing in Gaborone has injected fresh momentum into a region eager to harness its resources—solar, mineral and human—in pursuit of shared prosperity.
