The project was divided into three construction, operation and maintenance segments.

The Spanish company Isolux Corsán won the concessions for lots A and B, and a consortium of Eletronorte, Abengoa and Chesf won lot C.
A company was formed for each concession.

The lot A section from Tucuruí to Jurupari operated by LXTE is 527 kilometres (327 mi) long.

The lot B section operated by LMTE from Oriximiná via Jurupari to Macapá is 713 kilometres (443 mi) long.

The lot C section from Oriximiná to Manaus operated by MTE (Manaus Transmissora de Energia) is 586 kilometres (364 mi) long.

The estimated cost was about R$3 billion.

The project was financed by the Banco de la Amazonía.

Due to the environmental importance of the Amazon region the project had to minimise impact.

For this reason the transmission lines mainly run beside existing highways.

In many sections unusually high towers had to be built to carry the lines above treetops to avoid cuts.

The Isolux Corsán part of the project involved 4,000 workers living in fourteen camps.

It included a 70-kilometre (43 mi) section of swamp.

In the Alagados region between the Xingu and Amazon rivers the land is flooded in the rainy season and has deep mud in the "dry" season.

Use of large barges proved impossible without causing unacceptable environmental damage.

The solution was to use specially-built light barges propelled by a hydraulic excavator.

The excavator, placed at the front of the barge, would pull it forward using its scoop.

Buffalo trails showed where the deepest channels were.

The crossings of the Amazon, Trombetas and Uatumã rivers required huge towers.

The line crosses the Amazon at Jurupari island with a 1.2-kilometre (0.75 mi) span between 150 metres (490 ft) towers and a 2.2-kilometre (1.4 mi) span between 295 metres (968 ft) towers.

By comparison, the Eiffel Tower in Paris is 324 metres (1,063 ft) high.

Zhejiang Electric Power Transmission & Transformation Corporation of China, with the China Cable Corporation and Zhejiang Shengda Steel tower company, built the two largest towers and the main span across the Amazon River.
The main span is 2,148 metres (7,047 ft), and the strain section is 3,908 metres (12,822 ft).

Four 779.4-millimetre (30.69 in) stranded aluminium lines with a steel core were used for the conductors.

The pylons weigh 2,500 tonnes each.

Completion was planned for the end of 2011.

In April 2011 it was reported that the first tower had been completed, a 62-metre (203 ft), 24 ton structure on the Oriximiná – Manaus section.

The work was now scheduled for completion in December 2012, or at latest in July 2013.

The line reached Manaus in 2013.

Total investment was US$2.29 billion.

According to the government the project would reduce power generation costs by R$2 billion annually.

The next phase was a 750-kilometre (470 mi) extension from Manaus to Boa Vista, Roraima.
