IN SHORT: Botswana and Namibia signed a historic bilateral agreement on the sidelines of the AfDB Annual Meetings in Brazzaville on May 28 to jointly develop a $4 billion oil refinery. The project is designed to process Namibia’s offshore crude from the Orange Basin and deliver refined products to both landlocked Botswana and Southern African regional markets. The agreement is the most significant Southern Africa energy infrastructure deal since the East African Crude Oil Pipeline financial close in 2023.
Botswana and Namibia have committed to jointly building a $4 billion oil refinery in a landmark Southern African energy cooperation deal signed in Brazzaville, pairing Namibia’s rapidly developing Orange Basin offshore oil discoveries with Botswana’s geographic position and demand for refined petroleum products to create the region’s first new large-scale refining capacity in a generation. The agreement was signed on May 28 on the sidelines of the AfDB’s 61st Annual Meetings, where Southern African energy security was a recurring theme given the impact of the Hormuz crisis on regional fuel costs.
- Namibia’s Orange Basin, straddling the maritime border with South Africa, contains major offshore oil discoveries made by TotalEnergies, Shell and the state-owned Namcor over the past four years. The Venus discovery, estimated at up to 3 billion barrels, is among the largest made anywhere in the world in the past decade. First production is targeted in the late 2020s. The refinery deal positions Namibia to add domestic refining capacity that captures more value from these discoveries before they reach export markets.
- Botswana has no oil production but is among Southern Africa’s largest fuel consumers per capita on a purchasing power-adjusted basis. As a landlocked nation, it currently imports all refined petroleum products through South African and Mozambican corridors, paying significant logistics premiums. Refinery access through a Namibian facility with a coastal Atlantic export position addresses that dependency directly.
- The refinery location and financing structure have not been publicly specified beyond the bilateral agreement. Development finance institutions including the AfDB and the Development Bank of Southern Africa are expected to be anchor co-financiers. A public-private partnership structure involving TotalEnergies, which is already the lead operator of the Venus discovery, is regarded as the most likely execution vehicle.
- The Brazzaville signing adds to a growing pipeline of Southern African energy deals. The Eskom nuclear programme is in early World Bank discussions. The East African Crude Oil Pipeline is under construction. The Lobito Corridor railway rehabilitation is proceeding. The Botswana-Namibia refinery adds a new node in the Southern African energy and logistics map that has historically been dominated by South African infrastructure.
- Former AfDB President Akinwumi Adesina was simultaneously announced as Chairman of the Diamonds for Development Fund by the Botswana government and De Beers on May 29, adding to Botswana’s Brazzaville week. Adesina’s appointment positions Africa’s most decorated development banker in a role that directly addresses Botswana’s economic diversification challenge as diamond revenues face long-term structural pressure from lab-grown competition.
The Botswana-Namibia refinery agreement is consequential precisely because it is bilateral. Two smaller African economies, neither of which is a major continental power, have agreed to share infrastructure, share costs and share risk in a project that benefits both. That model, two countries pooling resources to build what neither could justify alone, is exactly the kind of pan-African cooperation that the AfDB’s New African Financial Architecture is designed to catalyse. It also addresses one of Botswana’s most persistent structural vulnerabilities: the complete absence of domestic energy production in a country that is seeking to industrialise and reduce its dependence on diamond revenue.
The Bigger Picture: Namibia’s Orange Basin oil is one of the most significant new hydrocarbon frontiers in the world. First production is still years away, but the bilateral refinery agreement confirms that Namibia is not planning to simply export crude and let others capture the refining margin. The Botswana partnership provides a natural market for refined products and a cost-sharing partner for the capital-intensive refinery construction. At $4 billion, the project is large but not unprecedented: it is comparable to the Dangote refinery at $20 billion or the Uganda-Tanzania pipeline at $5 billion. The question is whether the financing structure comes together faster than the development timelines that have historically plagued African energy mega-projects.
