China’s State Grid to construct longest transmission line in Brazil as part of Belo Monte hydroelectric project

Belo Monte Hydropower Complex

The State Grid Corp. of China has been awarded a contract to build and operate a second transmission line as part of Brazil’s massive Belo Monte hydroelectric power complex.

The US$2.2 billion line will be an 800kV, 2,550-kilometer-long link — the country’s longest — that will run from the 11.2-GW Belo Monte in north Brazil to Rio de Janeiro in the southeast. The deal also includes the construction of two new substations.

The transmission line will be the second constructed by State Grid as part of the Belo Monte project. The first, awarded to a consortium led by the Chinese company last year, is expected to be complete in December 2017, while the most recent is scheduled for completion in December 2019. reported earlier this month that Belo Monte developer Norte Energia had awarded a pair of contracts for the supply of mechanical equipment.

Power corporation Cemig Geracao e Transmissao SA had made a deal to acquire a 49% share in the plant from mining company Vale in April.

Belo Monte has a completion deadline of 2018, though developer Norte Energia filed a request for a construction extension this past June. A federal court rejected a request in July from from a public prosecutor to suspend work on the project because Norte Energia was accused of failing to consult properly with aboriginal groups potentially affected by Belo Monte.
