Biggest Africa infrastructure projects 2026

Africa is in the middle of the most ambitious infrastructure buildout in its history. From the world’s largest single-train oil refinery in Lagos to a transcontinental railway connecting the DRC’s copper mines to Angola’s Atlantic coast, the scale and ambition of projects currently under construction or in advanced financing across the continent are transforming the physical foundations of African economic growth.

This guide covers Africa’s biggest infrastructure projects currently under construction or approaching financial close in 2026, with project values, completion timelines, financing structures and the strategic significance of each.

1. Dangote Petroleum Refinery, Nigeria: $20 billion

The Dangote Petroleum Refinery on the Lekki Free Trade Zone peninsula outside Lagos is the world’s largest single-train oil refinery, with a nameplate capacity of 650,000 barrels per day. It is already fully operational and represents the single largest private industrial investment in African history.

The refinery cost $20 billion to build over more than a decade and has already transformed Nigeria’s energy economy: it currently supplies more than 90% of Nigeria’s domestic fuel demand, has begun exporting refined petroleum products to Europe and East Africa, and delivered jet fuel to Ethiopian Airlines in its first cross-border African airline supply. A pan-African IPO targeting a $40-50 billion valuation is expected imminently in 2026. A proposed expansion to 1.4 million barrels per day would make it the world’s largest single-site refinery by volume.

Impact: Structural elimination of Nigeria’s fuel import dependency. Continental energy security asset during the Hormuz crisis. Anchor for Nigeria’s downstream petrochemical sector.

2. Grand Ethiopian Renaissance Dam (GERD), Ethiopia: $5 billion

The Grand Ethiopian Renaissance Dam on the Blue Nile is Africa’s largest hydroelectric dam and one of the world’s largest, with an installed capacity of 5,150 megawatts. Construction began in 2011 and the dam has been generating power since 2022, with additional turbines coming online progressively. Full operational capacity is expected by 2026-2027.

The GERD is simultaneously Ethiopia’s most important infrastructure achievement, a geopolitical flashpoint with downstream neighbours Egypt and Sudan, and a model for African states financing strategic infrastructure through domestic bonds and national savings rather than external debt. Ethiopia financed a significant portion of the dam through voluntary deductions from civil servant salaries and domestic bond sales.

Impact: 5,150MW of renewable energy transforming Ethiopia’s power sector. Potential for regional electricity export. Ongoing diplomatic tensions with Egypt over Nile water flow.

3. Lobito Corridor Railway, Angola/DRC/Zambia: $8-10 billion total programme

The Lobito Corridor is Africa’s most strategically consequential infrastructure project under active development, connecting the copper and cobalt mines of Zambia and the DRC to Angola’s Atlantic port at Lobito through a rehabilitated and extended railway network. The total programme spans three national rail systems: the Angolan Benguela Railway (1,300km, rehabilitation financed at $753 million), the new Zambian extension (515km, new construction), and the DRC spur (315km, new construction).

The Africa Finance Corporation is assembling a $3-5 billion financing coalition including Citi, Standard Bank, Absa and Ecobank for the Zambian and DRC components. The US DFC committed $553 million to the Angolan rehabilitation. Financial close is targeted for Q4 2027, construction completion by 2030. The project is explicitly designed as the US and EU’s answer to Chinese infrastructure influence in Africa’s critical minerals corridor.

Impact: Reduces transit time for DRC/Zambia copper and cobalt from 30-plus days via Dar es Salaam to 10-12 days via Lobito. Reshapes Central African mineral export economics. Anchor for the US-China competition for African supply chains.

4. Lekki Deep Sea Port, Nigeria: $1.5 billion

The Lekki Deep Sea Port, located on the Lekki Peninsula outside Lagos, opened in 2023 and is Nigeria’s first deep-water port, capable of handling ultra-large container vessels that cannot be accommodated at Apapa. The port was developed by Tolaram Group and the Lagos State Government with Chinese financing through the China Harbour Engineering Company. It adds significant container handling capacity to West Africa’s largest economy and reduces congestion at Apapa, which has been a major logistics bottleneck.

Impact: Transforms Lagos’s container logistics. Reduces port costs for Nigerian importers and exporters. Anchor for the Lekki Free Trade Zone’s industrial development.

5. Nador West Med Port, Morocco: $5.6 billion

Morocco’s third deepwater port, opening Q4 2026, with initial container capacity of 5 million TEU expandable to 12 million, Africa’s first LNG terminal at 5 billion cubic metres per year, and 700 hectares of industrial and logistics zones. CMA CGM has committed to 3 million containers per year. EU financing of over €300 million backs the infrastructure. A companion deepwater port at Dakhla on the Atlantic coast follows in 2028.

Impact: Rivals Europe’s largest Mediterranean container ports at launch. LNG import capability strengthens Morocco’s energy security. Industrial zone anchors manufacturing investment along the Mediterranean corridor.

6. Bishoftu International Airport, Ethiopia: $12.5 billion

Ethiopia has begun development of a new international airport at Bishoftu, approximately 45 kilometres from Addis Ababa, which PM Abiy Ahmed Ali has described as “the largest aviation infrastructure project in Africa’s history.” The facility is designed to complement Bole International Airport and position Ethiopia as the continent’s dominant aviation hub, serving Ethiopian Airlines’ fast-growing network of 130+ international destinations.

Impact: Africa’s largest aviation infrastructure investment. Positions Addis Ababa as a genuine global hub comparable to Dubai or Doha for the African continent.

7. LAPSSET Corridor, Kenya/Ethiopia/South Sudan: $25 billion full programme

The Lamu Port-South Sudan-Ethiopia Transport Corridor is East Africa’s most ambitious multi-modal infrastructure programme, linking a new deepwater port at Lamu on Kenya’s north coast through a road, rail, pipeline and oil refinery network to South Sudan and Ethiopia. The Lamu port’s first three berths are operational. Road construction is advancing. The pipeline and railway components are in various stages of planning and financing. The full programme, if completed, would transform the Horn of Africa’s logistics architecture and give landlocked South Sudan and Ethiopia direct Atlantic Ocean access.

Impact: Transformative for East Africa’s freight logistics. Enables South Sudan oil exports. Provides Ethiopia with a second access point to the Indian Ocean. Timeline and financing remain uncertain for inland components.

8. Abidjan-Lagos Highway, West Africa: $15.6 billion

The 1,028-kilometre Abidjan-Lagos Highway will connect Ivory Coast, Ghana, Togo, Benin and Nigeria through a high-standard road corridor along West Africa’s most economically active coastline. The project is being developed under the African Development Bank and ECOWAS framework, with the highway designed to reduce transit times and costs for the approximately $10 billion in annual trade that flows along this corridor. It will pass through Abidjan, Accra, Lomé, Cotonou and Lagos, connecting the capital cities of five countries that together account for more than half of West Africa’s GDP.

Impact: Reduces Abidjan-Lagos transit time from 3-4 days to 10-12 hours. Enables cross-border industrial value chains across West Africa’s most populous corridor.

9. Standard Gauge Railway expansion, Kenya/East Africa

Kenya’s Standard Gauge Railway, Phase 1 of which connects Mombasa to Nairobi, is being extended toward Uganda and eventually the broader East African network. Phase 2A from Nairobi to Naivasha is operational. The Nairobi Commuter Rail rehabilitation, now financed by French AFD at $83 million as part of the Ruto-Macron bilateral package, will modernise the urban commuter network covering Syokimau, Embakasi, Ruiru, Kikuyu and Riruta-Ngong corridors. The SGR’s eventual extension to Kisumu on Lake Victoria and across to Uganda would create the East African rail network that planners have envisioned since the colonial era.

Impact: Reduces Mombasa-Nairobi freight costs by approximately 60% versus road transport. Urban commuter rail reduces Nairobi’s chronic traffic congestion. Regional extension would transform East African trade logistics.

10. Batoka Gorge Hydropower Project, Zambia/Zimbabwe: $5 billion

The Batoka Gorge Hydropower Project on the Zambezi River, downstream from Victoria Falls, is a bi-national Zambia-Zimbabwe project targeting 2,400 megawatts of hydroelectric capacity. It has been in planning for decades but financial close has remained elusive. General Electric and Power Construction Corporation of China have been involved in various iterations of the project. When operational, it would dramatically increase base-load power availability for both countries, currently among Southern Africa’s most power-constrained economies.

Impact: 2,400MW of reliable base-load power for Zambia and Zimbabwe. Transformative for both countries’ industrial and mining sectors. Financial close remains the key variable.

11. Inga III Hydropower Project, DRC: $14 billion (Phase 3 alone)

The Grand Inga Dam on the Congo River is the most ambitious energy project on the African continent, with a total potential hydroelectric capacity exceeding 40,000 megawatts, which would make it the world’s largest power facility of any kind. Phase 3 (Inga III) alone would add 11,000 megawatts. The project has been in various stages of planning and financing for decades, with South Africa, Spain and China all having been involved at different points. The DRC government is currently in negotiations with multiple potential investors and lenders. Financial close has not been achieved for any phase beyond the original Inga I and II facilities built in the 1970s.

Impact: If built, would supply the entire African continent with electricity. Has never moved beyond planning in its current ambitious form. Remains the most consequential unrealised infrastructure opportunity in the world.

Financing Africa’s infrastructure gap

Africa faces an infrastructure financing gap of approximately $100 billion per year, between what the continent needs to build and what public budgets, development banks and private investors currently provide. Closing that gap requires mobilising private capital at scale alongside public financing, which requires regulatory frameworks that protect investor returns, enforcement of infrastructure contracts, and transparent project development processes.

The major multilateral financiers active in African infrastructure include the African Development Bank, the World Bank Group, the European Investment Bank, the US DFC, China’s EXIM Bank and CDB, and bilateral development finance institutions including the French AFD, Germany’s KfW and the UK’s British International Investment. Private infrastructure funds, sovereign wealth funds from the Gulf, and pan-African investment vehicles including the Africa Finance Corporation are increasingly significant alongside the multilaterals.

The Bigger Picture: Africa’s infrastructure story in 2026 is not about what the continent lacks. It is about what is being built. The Dangote Refinery exists. The Lobito Corridor is being financed. Nador West Med opens this year. The GERD is generating power. A $12.5 billion airport is under development in Bishoftu. These are not plans. They are assets under construction or in operation, financed with real capital, generating real economic returns. The infrastructure gap remains enormous. But the direction of travel has changed. Africa is building, at scale, with a diversity of financing sources that was unavailable a decade ago. That is the most important structural change in the continent’s economic story since the AfCFTA was established.
