The Bui Dam is a 400-megawatt hydroelectric project built on the Black Volta river at the Bui Gorge, at the southern end of Bui National Park. The Bui hydro-electric dam had first been envisaged in 1925 and remained on the drawing board since the 1960s, when Ghana’s largest dam, the Akosombo Dam, was built further downstream on the Volta River. By 1978 planning for the Bui Dam was advanced with support from Australia and the World Bank. However, four military coups stalled the plans. At the time Ghana began to be plagued by energy rationing, which has persisted since then. This created goodwill among the population towards the construction of the plant. In 1992, the project was revived and a first feasibility study was conducted by the French firm Coyne et Bellier.
