Bui Dam in the Black Volta River, Ghana

The recently Chinese-built Bui Dam was planned since the 1920s as part of the Volta River Project for producing electricity fby processing the country’s bauxite.


Description

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.

Project Details and Actors
Project DetailsBui Dam is a gravity roller-compacted concrete dam located at the Bui National Park in Ghana.

The dam generates 400MW of power and facilitates irrigation of about 30,000ha of land. Construction was initially estimated at $622m, but a cost review conducted in 2012 raised that amount by $168m. [2]

Just downstream of the dam on the left bank is the dam's powerhouse. The intake at the reservoir feeds water through three penstocks to the three separate 133 MW Francis turbine-generators. Each turbine-generator has a step-up transformer to increase the voltage to transmission level. A fourth unit, with a penstock on the spillway, will provide four megawatts for station service and black start power, and will provide minimum flow to maintain river levels if the main units should be shut down. The power station will have an installed capacity of 400 megawatts and an estimated average annual generation of 980 gigawatt-hours (3,500 TJ). The power station's switchyard is located 300 metres (980 ft) downstream. Four 161 kV transmission lines connect the substation to the Ghana grid [3].

Impacts
Environmental ImpactsVisible: Biodiversity loss (wildlife, agro-diversity), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Large-scale disturbance of hydro and geological systems, Reduced ecological / hydrological connectivity, Global warming
Potential: Floods (river, coastal, mudflow)
OtherLoss of a large part of Bui National Park, a protected savannah with pristine river forests, spectacular landscapes, and a diversity of species. The country’s largest hippopotamus population (Hippopotamus amphibius) could face extinction. The dam will be a source of greenhouse gases (4). (1).
Health ImpactsPotential: Exposure to unknown or uncertain complex risks (radiation, etc…)
OtherRisk of schistosomiasis ( bilharzia).
Socio-economic ImpactsVisible: Displacement, Loss of traditional knowledge/practices/cultures, Land dispossession, Loss of livelihood, Loss of landscape/sense of place, Other socio-economic impacts
Potential: Violations of human rights
Other2500 people displaced. Dowstream fishing has suffered through reduction in catch and unregulated water releases from the dam while farming has seen a reduction in farm sizes

2,500 people displaced. Fishing downstream has suffered.
