Sierra Leone has crowned one of the most consequential diplomatic chapters in its recent history with the signing of the US$25 billion African Atlantic Gas Pipeline (AAGP) Intergovernmental Agreement, a landmark regional infrastructure project that not only advances West Africa’s energy integration but also reinforces the country’s growing stature as one of Africa’s emerging energy destinations. Signed during the 69th Ordinary Session of the ECOWAS Authority of Heads of State and Government in Lungi under the Chairmanship of President Julius Maada Bio, the agreement represents a defining conclusion to Sierra Leone’s stewardship of the regional bloc.
The milestone comes at a time when Sierra Leone’s energy sector is enjoying unprecedented momentum. Over the past year, the country has strengthened its position through significant upstream petroleum agreements with global energy companies including ENI, Shell , Marginal Energy and FA Oil, while implementing reforms that have improved investor confidence, modernized petroleum legislation and expanded international engagement. The pipeline agreement adds another important dimension to that progress, positioning Sierra Leone not only as an attractive exploration frontier but also as a strategic participant in regional energy infrastructure capable of connecting African resources with African markets.
Stretching approximately 6,900 kilometres along Africa’s Atlantic coastline, the African Atlantic Gas Pipeline will connect Nigeria’s vast natural gas reserves to Morocco through thirteen coastal countries, including Sierra Leone, before providing onward access to European markets. With an estimated investment of US$25 billion and an annual capacity of up to 30 billion cubic metres of natural gas, the project ranks among the world’s largest gas pipeline developments and is expected to strengthen regional energy security while supporting industrialisation and economic growth across West Africa.
For President Julius Maada Bio, the signing represents more than the conclusion of another regional agreement. It reflects his broader vision of transforming ECOWAS from a platform of declarations into one that delivers practical infrastructure capable of improving lives and unlocking Africa’s economic potential.
“For generations, the Atlantic has carried Africa’s wealth away from our shores. With this Agreement, we turn the tide. This pipeline will carry energy, opportunity and prosperity along our coastline, from West African soil to West African homes and industries.”
President Bio described Sierra Leone as proud to host what he called a defining chapter in Africa’s energy future, emphasizing that the agreement demonstrated what regional cooperation could achieve when backed by political commitment and a shared development agenda.
“Sierra Leone is proud that this defining chapter in Africa’s energy future has been written here, on our soil, in a spirit of unity that reflects the very best of what ECOWAS can achieve together.”
The agreement also represents the culmination of more than four years of sustained technical engagement led by the Petroleum Directorate of Sierra Leone (PDSL). Since signing the Memorandum of Understanding in 2022, the Directorate has represented Sierra Leone throughout successive ministerial and technical negotiations, contributed to shaping the project’s legal and institutional framework, coordinated national technical inputs and ensured that Sierra Leone’s interests remained firmly embedded throughout the negotiation process.
Under the leadership of Director General Eng. Foday B.L. Mansaray, the Petroleum Directorate has steadily evolved into one of West Africa’s most respected petroleum institutions. Alongside pursuing upstream investment opportunities and strengthening regulatory reforms, the Directorate has expanded Sierra Leone’s international energy partnerships while helping elevate the country’s profile within Africa’s petroleum industry. The African Atlantic Gas Pipeline Agreement stands as another significant milestone in that journey.
Speaking after the signing, Eng. Mansaray stressed that the significance of the agreement extends well beyond the construction of a gas pipeline.
“This Agreement is about far more than the development of a gas pipeline. It is about regional integration, shared prosperity and energy security. It is also about creating new opportunities for industrialisation, employment and sustainable economic growth across West Africa.”
Reflecting on Sierra Leone’s contribution to the project since its inception, Mansaray said years of technical cooperation had now been translated into a binding legal framework capable of transforming regional energy cooperation.
“Today’s signing transforms years of technical cooperation into a formal legal framework that will guide implementation of one of Africa’s most strategic energy infrastructure projects. Sierra Leone is proud to have contributed to this process from its inception in 2022 and looks forward to working with our regional partners as implementation progresses.”
He further commended President Bio’s leadership, noting that Sierra Leone’s active participation reflected the President’s broader commitment to strengthening regional partnerships while advancing national economic development. The Petroleum Directorate believes the project will deliver substantial benefits for Sierra Leone through expanded gas-to-power generation, increased industrial development, reduced dependence on imported refined fuels, new employment opportunities, skills development and additional transit-related revenues.
The agreement complements Sierra Leone’s Medium-Term National Development Plan 2024–2030, which prioritizes diversified energy sources, improved electricity access and accelerated industrial growth. It also aligns with the country’s broader petroleum strategy that has seen renewed investor confidence driven by improved seismic data acquisition, strengthened petroleum legislation and an increasingly transparent regulatory environment.
For Sierra Leone, the timing could hardly be more significant. As President Bio concludes a widely praised ECOWAS Chairmanship that saw the successful hosting of regional leaders in Lungi, the signing leaves behind more than the memory of a well-organized summit. It leaves a tangible legacy—one anchored in regional integration, shared infrastructure and practical cooperation capable of reshaping West Africa’s economic future.
For international investors, the message is equally compelling. The recent succession of petroleum agreements with major international companies, combined with sustained institutional reforms and now participation in one of Africa’s largest regional gas infrastructure projects, underscores Sierra Leone’s growing credibility within the global energy industry. The country is steadily transitioning from an emerging exploration frontier into a strategic energy partner with ambitions that extend beyond its offshore resources.
The African Atlantic Gas Pipeline therefore represents more than another regional infrastructure project. It signals Sierra Leone’s arrival as an increasingly influential player in Africa’s evolving energy landscape—a country leveraging diplomacy, sound petroleum governance and regional cooperation to position itself at the forefront of West Africa’s next chapter of energy-driven development.
