Sierra Leone: Bumbuna Hydro II
Scaling up access to renewable baseload power
Challenge
Sierra Leone has an electrification rate of just 26.2%, one of the lowest in sub-Saharan Africa. The Government of Sierra Leone’s (GoSL) National Renewable Energy Action Plan recognises the potential of the country’s rivers to generate baseload hydropower as part of wider efforts to reduce the country’s dependency on fossil fuels. Following the impact of the Ebola virus on Sierra Leone’s people and economy, the President’s Recovery Priorities include access to energy.
An existing, government owned, hydropower facility was commissioned in Bumbuna in 2009. Generating 50MW of hydropower, the facility supplies electricity to Freetown and Kilkenny. However, supply is not available in the dry season and customers rely on polluting diesel generators to provide power for their homes and businesses.
Solution
Located on the Upper Seli River, 230km north east of Sierra Leone’s capital, Freetown, the Bumbuna Hydro II is planned to be implemented in two phases. By adding new generation capacity to the existing Bumbuna dam (90-160MW) and building a new dam at Yiben (53MW), 35km upstream of the existing Bumbuna I facility, the project will enable delivery of significant additional power to the national grid but more importantly increase the generation during the dry season thanks to the seasonal storage capability to be built at Yiben. Both the Bumbuna extension and Yiben will also be linked to the West Africa Power Pool (WAPP) via the recently constructed Côte d’Ivoire, Liberia, Sierra Leone and Guinea (CLSG) transmission line.
This ambitious project is being delivered by experienced renewables developer, Blue International (formerly Joule Africa) through its local project company, Seli Hydropower. PIDG Technical Assistance (PIDG TA) has supported Bumbuna Hydro II’s early development via returnable and technical assistance grants to fund an embedded advisor to the GoSL. The involvement of PIDG company, the Emerging Africa and Asia Infrastructure Fund (EAAIF) has also been central to enabling the project to progress to this stage. InfraCo Africa’s involvement, alongside that of a range of private sector and development finance institutional investors, is designed to enable this large-scale project.
It is anticipated that the project will generate substantial levels of local employment throughout the anticipated 49 month construction period. Bumbuna Hydro II will also deliver long term operational and management jobs. Consumers will benefit from increased reliability of power and will also see cost savings via affordable tariffs and reduced reliance on expensive diesel back-up generation.
