The concession to build and operate the line from Manaus north to Boa Vista, Roraima, was auctioned in September 2011 and the agreement with the Transnorte consortium was signed in January 2012.
Completion was scheduled for January 2015 at an estimated cost of about R$890 million.

Alupar has 51% equity in the consortium and Eletronorte, a subsidiary of Eletrobras, has 49%.

The project was stalled due to delays in the licensing process.

In the interim, the state remained dependent on the Linhão de Guri from Venezuela, an ageing and unreliable line with steadily less power provided by Venezuela.

Boa Vista, a city of over 320,000 people, suffers from constant power outages and blackouts.

The route chosen by Transnorte Energia, the concessionary company, would follow the BR-174 federal highway and was identified as alternative 1 in the 2014 Environmental Impact Assessment, which included studies of the indigenous component.

Of the four routes considered, the 721-kilometre (448 mi) alternative 1 had the least environmental impact.

123 kilometres (76 mi) of the line would cross the Waimiri Atroari Indigenous Territory.

250 support towers would be built in the indigenous territory.

The only route that completely avoided the territory, 902 kilometres (560 mi) long, would involve opening roads in a better preserved region of the Amazon rainforest, and would cause great pressure to occupy that region.
By following the BR-174 infrastructure corridor the chosen alternative would avoid further fragmentation of the forest.

The Fundação Nacional do Índio (FUNAI – National Indian Foundation) issued a letter of consent in November 2015.

President Dilma Rousseff announced that a provisional licence would be granted early in December 2015.

The preliminary licence was granted to Transnorte Energia by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) on 9 December 2015.

In January 2016 the Roraima Secretary for Planning said the connection to the Linhão de Tucuruí should reach Boa Vista in 2018.

However, the state was still considering installing another thermoelectric power station to meet immediate demand and was looking into a hydroelectric installation in Caracaraí.

In February 2016 a federal judge issued an injunction that prohibited work on the 500 kV line until the Waimiri-Atroari indigenous people had been consulted.

He said IBAMA had ignored the requests of the indigenous people and forced through the project without consultation, as required by the Indigenous and Tribal Peoples Convention, 1989.

Although public hearings had been held in the cities of Presidente Figueiredo, Manaus, Rorainópolis and Boa Vista, none had been held in the Waimiri Atroari Indigenous Territory.

A leader of the indigenous people said FUNAI could not speak on their behalf concerning the project.

The Convention required free and informed prior consultation.
The Waimiri Atroari had already suffered from a history of "violent pacification", illegal mining and flooding of sacred territories, as with the Balbina Dam.

Construction would involve hundreds of workers entering the territory, where FUNAI considers that more than 1,600 Indians are "recent contact".

The Indian leaders said that there were already problems in the community and conflicts since BR-174 was opened.

In March 2016 a federal judge responded to a request by the attorney general and suspended the injunction that was preventing construction of the line.
He said there had been undue judicial interference in the licensing process for the project, which was of a national strategic nature and would be undertaken entirely on federal land along the BR-174.
