Balbina Hydroelectric Dam, Amazonas, Brazil

Widely considered as one of the worst hydroelectric projects ever realized, Balbina is highly inefficient in producing electricity and a major GHG emitter, has flooded vast areas of rainforest, destroyed local biodiversity and displaced local communities.


The Balbina dam is operated by Eletronorte and was inaugurated in 1989. It came as part of a national integration and economic growth offensive (the Programa de Aceleração do Crescimento, PAC) that was pushed forward by Brazil’s military government in the 1960s and 1970s in the Northern Amazon. The start of dam constructions in 1979 followed the controversial construction of the BR-174 highway (see related case entry in the EJAtlas) that cut through dense rainforest and the land of the Waimiri Atroari community (self-denomination: Kinja), which had so far been living rather isolated and whose presence was seen as disturbing. At the point of dam construction, the Balbina area was inhabited by riverine communities along the Uatumã as well as the Waimiri Atroari indigenous group. However, the spread of diseases and extreme violence exerted by the military during road construction in the 1970s led to a drastic decline and the near distinction of the indigenous population, from an estimated 3,000 in the 1970s to 332 people in 1986. Moreover, the isolated Pirititi indigenous group has widely disappeared since then. In 1979 mining groups linked to the Paranapanema group started to invade nearby indigenous lands in which large cassiterite deposits were found. The military government controversially dissolved the demarcation of the indigenous land to regularize mining operations that continue until today (see also related case entry in the EJAtlas) and expropriated an area of 10,300 km2 for public utility, superimposing it to the territory of the Waimiri Atroari group. This permitted the eventual flooding of approximately 2,928 km2 through the Balbina project, including at least eight indigenous villages, leading to the displacement of about one-third of the surviving indigenous population and about 3,000 riverine families downstream of the dam [1] [2] [3] [4] [5] [6] [7] [8] [9].

Project Details and Actors
Project details

The Balbina hydroelectric dam is situated 100 km north of Manaus by the Uatumã river and cost about 700 million Reais. Work on the dam started in 1979, the inauguration took place in 1989. Run by state-controlled Eletronorte (full name: Centrais Elétricas do Norte do Brasil S.A.), which holds the power monopoly in Northern Brazil, it encompasses five generators and was conceptualized to produce 250 MW, while effectively the output is in average 112.2 MW according to 1989 numbers, and far less according to newer numbers, making the project already questionable from a technical point of view [1][2][3][10][12].

Briefly explain:As outlined above, the Balbina dam came with tremendous socio-environmental costs and has been widely criticized for its inefficiency. Together with other large-scale developmentalist-extractivist activities in the area, the dam brought the destruction of indigenous livelihoods and ways of living and a series of environmental injustices. Fearnside (1989) classified the dam as a ‘pharaonic work’ that demanded enormous governmental and societal effort while bringing virtually no economic returns as the number of generated megawatts remains insignificant [10].
