ArcelorMittal Brazil is supplying 50,000 mt of steel for the biggest ongoing construction project in the country- the $26 billion Belo Monte hydroelectric dam complex on the Xingu River, in the northeastern state of Para -- the company said Friday in a statement.

The volume of steel being supplied includes rebar, welded mesh, strands for pre-stressed concrete, structural steel beams, nails, annealed wire and steel plate to be used in the construction of the turbines and the dam, as well as plumbing design.

The first shipment took place in October 2012 and so far 30,000 mt have been supplied. An additional 20,000 mt are expected to be delivered by the end of 2017, the company said, without disclosing contract values.

The steelmaker said some of the biggest challenges of such a massive project are in logistics and transportation, given local climate conditions and the distance of the plants from the construction site.

"The synergy between our commercial team and our logistics team has been essential in meeting customer expectations," said Rodrigo Aguiar, implementation engineer at ArcelorMittal's sales management team in Minas Gerais.

Once completed, the hydroelectric dam will significantly increase the supply of renewable electricity in Brazil.

The plant's planned installed capacity would be 11,233 MW, which corresponds to 40% of residential consumption and 10% of total consumption in the country.

This will make it the second-largest hydroelectric dam complex in Brazil and one of the world's largest in installed capacity, behind the Three Gorges Dam in China and the Brazilian-Paraguayan Itaipu Dam.

The first of the dam's 27 turbines is expected to be operational by late 2015 or early 2016.

ArcelorMittal has five units involved in the supply of the project: Piracicaba, Sao Paulo, Cariacica, Juiz de Fora and from the joint venture Belgo Bekaert Arames.
