China’s SEPCO1 finishing high-voltage transmission line in Brazil

24 August 2018

China’s Shandong Electric Power Construction Corporation 1 (SEPCO1) is expected to complete in February 2019 the construction of the second high-voltage transmission line between the Belo Monte hydroelectric plant in the State of Pará and Rio de Janeiro, Brazil, over a distance of 2,550 kilometres, according to the Xinhua news agency.


It is the world’s longest high voltage power transmission line.


SEPCO1 is working on two lines at the same time, one in the State of Minas Gerais and the other in the State of Tocantins, in a project called Bipolo II, whose completion was scheduled for late May.


The Bipolo II of Belo Monte will send electricity from the Xingu River, in Pará, to the Southeast region, to the municipality of Nova Iguaçu in Rio de Janeiro.


The end of the work coming sooner than expected is due, according to Aldo Camargo, director of the project for one of the transmission lines, to good cooperation between Brazilian and Chinese workers.


Construction of the lines began in August 2017 after China’s State Grid Brazil Holdings was awarded the concession for the transmission line valued at 988 million reais in July 2015.


State Grid had already won the first Belo Monte transmission line auction for the Southeast region. At the time, the company had a stake of 51% in a consortium with Furnas Centrais Elétricas (with a 24.5% stake) and Eletronorte (24.5%).


State Grid is a Chinese state-owned company that has been in Brazil since 2010, when it acquired seven national power transmission companies. (macauhub)
