Algeria has begun construction on a key section of the Trans-Saharan Gas Pipeline, reviving one of Africa’s most ambitious energy infrastructure projects and advancing plans to transport Nigerian natural gas to Europe through Niger.
The development marks a significant milestone for a project that has remained largely on the drawing board for decades. Algerian officials formally launched work on the southern section of the pipeline as Europe continues to seek diversified energy supplies and African producers look to expand export opportunities.
Why the project matters
The Trans-Saharan Gas Pipeline has gained renewed strategic importance amid shifting global energy markets and Europe’s search for alternative gas suppliers. Once completed, the project would create a direct corridor linking Nigeria’s vast gas reserves with Algeria’s export infrastructure serving European consumers.
The latest development builds on previous efforts by the three participating countries to move the project forward. Africa Briefing previously reported on renewed cooperation between Algeria, Nigeria and Niger aimed at accelerating implementation of the long-delayed initiative.
Construction begins in southern Algeria
Algerian Energy and Mines Minister Mohamed Arkab joined representatives from Nigeria and Niger to inaugurate the first welding operations on the Algerian segment of the project.
The section under construction is expected to extend roughly 1,200 kilometres from Algeria’s border with Niger to Aoulef, where it will connect with the country’s existing gas transmission network. From there, supplies would flow to Algeria’s export facilities and onward to European markets.
The wider Trans-Saharan Gas Pipeline is planned to stretch more than 4,000 kilometres from Nigeria’s gas-producing regions through Niger before linking with Algeria’s energy hub at Hassi R’Mel.
Officials from the three countries have repeatedly described the project as a strategic investment that could unlock new export revenues, strengthen regional integration and support economic development across the Sahel.
Europe seeks new energy sources
European governments have intensified efforts to diversify energy imports in recent years, creating fresh momentum for large-scale energy projects connecting African producers to overseas markets.
Nigeria holds some of the world’s largest proven natural gas reserves, yet much of that potential remains underdeveloped due to infrastructure constraints.
The pipeline also aligns with Nigeria’s broader ambition to strengthen its position in international energy markets. An earlier Africa Briefing analysis examined how Nigeria could emerge as a leading oil and gas supplier to Europe as demand grows for diversified sources of supply.
Industry estimates have previously suggested the completed pipeline could transport up to 30 billion cubic metres of gas annually, although final capacity will depend on project design and commercial agreements.
A project delayed by security and financing concerns
The Trans-Saharan Gas Pipeline was first proposed decades ago but has faced repeated delays due to financing challenges, security concerns across parts of the Sahel and uncertainty over commercial viability.
Political instability in Niger and broader regional security risks have also complicated efforts to move from planning to construction.
Despite these challenges, Algeria, Nigeria and Niger renewed their commitment to the project in recent years, commissioning updated technical studies and advancing discussions on implementation.
Officials say the latest construction activity demonstrates that the project is finally moving beyond planning and into execution.
Strategic implications for Africa
Beyond its commercial value, the pipeline is increasingly viewed as a test case for African infrastructure integration and cross-border energy cooperation.
Analysts argue that successful completion could boost investment, generate transit revenues and strengthen Africa’s position within global energy markets. It could also reinforce Algeria’s role as a gateway connecting African energy resources with European consumers.
While major construction work remains ahead, the start of activity on the Algerian segment represents the clearest indication yet that the long-discussed project may finally become reality.
