At Yiben, the dam there will measure 83 metres (272 ft) in height and will be 730 metres (2,400 ft) wide. It will be a "roller compacted concrete (RCC) gravity dam", creating a lake with a surface area measuring 115 square kilometres (44 sq mi). The powerhouse at Yiben will have

The 88 megawatts generated at
Bumbuna II, will be evacuated via a new 225kV double-circuit transmission line to a substation located about 4 kilometres (2 mi) south-west of the Bumbuna II powerhouse. The 55.4 megawatts generated at Yiben will be transferred to Bumbuna II, thorough a new

At
Bumbuna, a new intake channel will be built approximately 400 metres (1,300 ft) upstream of the existing dam. Two Francis-type turbines each rated at 42.15 megawatts and one 3.7 megawatts turbine will be installed here for a total of 88 megawatts in new capacity.

Bumbuna I Hydropower
Station is a 50 megawatt installation owned by the government of Sierra Leone. The power station which cost US$ 327 million to build, was commissioned in 2009. However its output is not enough to meet the country's electricity needs.

The new plan is to build a new power station (Bumbuna II), with capacity of 143 megawatts, adjacent to the first one with capacity of 50 megawatts (Bumbuna I). This involves expansion of the
Bumbuna I Dam and the construction of a new dam at

The 50 megawatts generated at
Bumbuna I is transferred to Freetown via a 161kV single-circuit transmission line that measures about 200 kilometres (124 mi). It enters the national grid there.
