The company

Our history & purpose

From the first pre-feasibility study to commissioning, more than three decades have shaped the Kinguélé Aval project.

Our purpose

Producing renewable energy in the service of Gabon

Our ambition is simple: to help deliver reliable, competitive renewable electricity able to support growing energy demand, particularly in the Libreville region.

Meeting electricity needs Electricity demand is rising in Gabon, driven by households, public services, businesses and industry. Kinguélé Aval will strengthen the Libreville Interconnected Grid by injecting around 205 GWh per year — nearly 13% of the capital’s needs — improving access for homes, hospitals and schools.
Supporting local development The project creates jobs and mobilises local skills. During construction it mobilises over 800 people; in operation it will sustain skilled jobs and strengthen expertise in the hydroelectric sector.
Building durable infrastructure Kinguélé Aval harnesses Gabon’s hydroelectric potential to produce renewable energy and reduce reliance on fossil fuels. Designed to limit its impact, it sits on a river already developed upstream, on a long-studied site with existing access road and transmission line.
Setting a national benchmark As Gabon’s first public-private-partnership hydroelectric dam, Kinguélé Aval is a benchmark for financing, building and operating sustainable infrastructure — serving the country’s energy transition.
