Aliko Dangote's second mega-refinery now has an address. After months of speculation, competing presidential statements and an awkward diplomatic episode, Africa's richest man has settled on Kenya's Lamu port as the site of a planned 700,000-barrel-per-day refinery, an investment estimated at up to $20 billion, according to The Exchange Africa. For Tanzania, which had appeared to be the front-runner as recently as April, the decision represents a significant strategic loss.
From Tanga to Lamu in a matter of months
The story began publicly at an infrastructure summit in Nairobi in April, where Dangote told a panel featuring Kenyan President William Ruto and Ugandan President Yoweri Museveni that he was ready to build an identical copy of his Lagos facility in East Africa. Museveni even suggested that Ugandan crude originally earmarked for export through the East African Crude Oil Pipeline could become the plant's first feedstock, with additional supply later from South Sudan and the Democratic Republic of Congo. At that point, Tanga on the Tanzanian coast was the location everyone was talking about.
Trouble started when Ruto appeared to announce Tanga as the site before Tanzanian President Samia Suluhu Hassan had been consulted. The diplomatic stumble grabbed headlines, yet analysts quoted by The Exchange Africa argue that the deeper reasons for the switch were structural rather than political.
Port depth decided the race
A refinery of this magnitude needs a steady stream of Very Large Crude Carriers, the supertankers that move up to two million barrels at a time. Lamu, and to a lesser extent Mombasa, offers deep-water berths able to handle those ships with less congestion. Tanga's harbour is comparatively shallow, which would have meant costly dredging or transshipment arrangements.
The project demanded speed, predictability and co-investment. Kenya delivered all three, while an 18-month land-permitting process in Tanzania proved a deal-breaker, according to industry executives cited in the report.
Speed matters enormously for a project that Dangote hopes to complete in roughly four years. Every month of delay adds financing costs and pushes back revenue. Investors in large industrial plants place heavy weight on whether governments can grant land, environmental approvals and utility connections on predictable timelines.
The Hormuz shock changed the calculus
The urgency behind the plan comes from events far from Africa. When conflict involving Iran led to the closure of the Strait of Hormuz earlier this year, roughly a fifth of the world's oil and gas shipments were disrupted. Most of West, East and Southern Africa had relied on refined products imported from the Middle East, leaving them painfully exposed. Al Jazeera reported that neighbours including Cameroon, Togo, Ghana and even Tanzania turned to Nigeria for supplies as Gulf cargoes dried up.
Dangote's Lagos refinery, with capacity of 650,000 barrels per day, emerged as a winner from that crisis. Africa Briefing, citing Reuters, reported that the plant was operating at full capacity and had shipped at least 17 gasoline cargoes to African markets while expanding fertiliser exports. It even received orders for scarce jet fuel from outside the continent.
What Lamu could mean for East Africa
A Kenyan refinery would cut the distance between production and consumption for a region that currently imports nearly all of its petrol, diesel and aviation fuel. Shorter supply chains can reduce shipping costs, limit exposure to foreign currency swings and lower the risk of shortages when global routes are disrupted. Landlocked economies such as Uganda, Rwanda, Burundi and South Sudan could benefit from more reliable deliveries, assuming pipeline and road links are strengthened.
The project could also revive Lamu port, which was developed as part of the ambitious LAPSSET corridor but has struggled to attract traffic since opening. A refinery would create anchor demand for shipping services, warehousing and petrochemical industries around the port, and generate thousands of construction jobs.
The risks no one should ignore
Large refineries are notoriously difficult to deliver on time and on budget. Dangote's Lagos plant took years longer than first planned and faced disputes over crude supply and regulatory approvals before reaching full output. Replicating it in Kenya will require secure feedstock contracts, financing from banks comfortable with East African risk, and consistent policy from governments that change through elections.
Environmental concerns are another factor. Lamu's old town is a UNESCO World Heritage Site, and its surrounding mangroves and fisheries support local livelihoods. Community groups have previously challenged coal and port projects in the area, and they are likely to demand rigorous impact assessments and fair compensation.
Lessons for Tanzania
For Tanzania, the episode offers a hard lesson in investment competitiveness. Diplomatic warmth and attractive incentives matter, but large investors ultimately prize infrastructure readiness and bureaucratic speed. Streamlining land permitting and upgrading port depth could help the country win the next major industrial project, whether in refining, fertiliser or critical minerals processing.
A continent building its own energy chain
Taken together, the Lagos plant and the planned Lamu refinery signal a shift in how Africa thinks about energy. For decades the continent exported crude and imported finished fuel, sending value and jobs abroad. If both projects succeed, Africa could refine a much larger share of its own oil, trade it across borders under the African Continental Free Trade Area and gain real insulation from shocks in the Gulf.
