Extension of Tucuruí transmission line to Roraima, Brazil

A new government decree is advancing the start of construction of an electrical transmission line between Boa Vista and Manaus, crossing through the indigenous reserve of the Waimiri Atroari, who have been opposing the project but were not consulted.


In the beginning of 2019, Brazil’s new government announced the construction start of an electrical transmission line from Manaus to Boa Vista, as an extension of the existing Tucuruí transmission line. It would connect the isolated state of Roraima to the Brazilian energy grid, following the same corridor as the BR-174, including about 125 kilometers running through the territory of the Waimiri Atroari. The line had been proposed since the controversial constructions of BR-174 highway in the 1970s but it was especially pushed forward in the last decade. It has however faced opposition from the Waimiri Atroari group as well as regional politicians and non-government organizations. Looking back on a long history of violent conflict and ‘development’ interventions (see also related cases of the BR-174 construction, the Pitinga mine and the Balbina hydroelectric dam in the EJAtlas), leading to the group’s almost-extinction in the 1980s and an ongoing struggle for basic rights, the Waimiri Atroari (self-denomination: Kinja) today consists of 31 villages with a total number of 1,600 – 2,000 people.

Project Details and Actors
Project DetailsTransnorte Energia S.A., a consortium between the companies Alupar (51%) and Eletronorte (49%), holds the concession for the transmission line since 2011 and was controversially granted a preliminary environmental license for the construction in 2015 . The section of the line would have a capacity of 500 KW and a total length of 721km. It would connect Roraima to Brazil’s central energy grid and thereby extend the existing Tucuruí transmission line. Extending over 1,800 kilometers, it leads from Pará to Manaus, Amazonas, and supplies homes and industries in the Northern Amazon region – particularly Vale’s aluminum industries in Pará and the Polo Industrial in Manaus – with hydroelectricity from Tucuruí, Brazil’s first mega dam.

According to a previous environmental impact assessment issued in 2014, the route along the BR-174 was considered the least environmentally harmful one among several evaluated options, but completely failed to take the indigenous component into account. 125 kilometers would run through the Terra Indígena Waimiri Atroari, which encompasses a total area of 2,585,910 hectares shared between the states of Amazonas and Roraima and also used to be home to a minority of isolated Piriutiti tribes. [1] [2] [3][6][10]

Estimated investment sum: R$ 1,062 billion [3]

Currently, Roraima receives 70 percent of its power from the Guri hydroelectric dam in Venezuela and faces regular power cuts. [9]

Development of AlternativesAs an alternative to the transmission line, the state of Roraima had been examining wind and solar power projects. While these would avoid the controversial crossing of indigenous livelihoods and presumable ecological conflicts, viability studies have also shown that these alternative plans would result cheaper. [9] [10]
Do you consider this as a success?Not Sure
Why? Explain briefly.The Waimiri Atroari community is again confronted with interventions into its livelihood and the violation of basic rights. Studies have shown the probable socio-environmental damages of the project, while alternative energy models have so far been omitted. With the transmission line, the state of Roraima would receive its energy supply from one of the world’s largest and most controversial hydroelectric projects, the Tucuruí dam in Pará.
