[2] The project supplements power production from Akosombo Dam, for the melting of aluminium at VALCO in Tema.

[3] Because the reservoir upstream of the dam is relatively small, the plant operates as a "run-of-the-river" project, with river flow controlled at Akosombo.

The design head of water at the plant is 11.75 metres (38.5 ft); the low head required the use of unusually large turbines for their power rating, with a Francis runner diameter of 8.2 metres (27 ft).

Other components of the project include a 161 kV switchyard and transmission lines, four villages constructed to house people displaced by the project, and road construction.

Bilharzia is a health hazard in the region which has increased since the construction of the dam.
