Project Overview


Bumbuna II is a key part of the Government’s long-term Energy Strategy to provide more electricity to households and businesses. It will add a further 143MW of power to Sierra Leone. Importantly, it will also provide a minimum of 80MW of reliable electricity throughout the year.

Bumbuna II is a hydro-electric power project and will be located on the Upper Seli River in the Northern Province of Sierra Leone and when complete, will provide reliable, affordable electricity all year round.

The project includes:

  • Building an extension to the existing Bumbuna I facility which will include 3 new turbines
  • Building a new dam 32 km upstream at Yiben which will include 2 new turbines
  • Creating a new reservoir of water behind the Yiben dam wall covering approx. 115 km2
  • Creating buffer zones around the infrastructure to protect the community from potential hazards such as high flood, dust, noise, or electrocution
  • Building improved access roads

Once generated, the electricity will be distributed by a new 225kV transmission line running from Yiben in the north of Sierra Leone, to Freetown in the West. This transmission line will also link up with the new Cote d’Ivoire, Liberia, Sierra Leone and Guinea (CLSG) extension, joining up with the West African Power Pool
