Following an auction organised by the National Electricity Agency (ANEEL) of Brazil for around 6,000 km of new electrical transmission lines divided into nine lots, Cobra IS - through its Brazilian subsidiaries - was awarded three lots:

• Lot 3, as part of a public-private partnership involving a 349 km 500 kV power transmission line and the extension of two existing substations in Minas Gerais State. The associated investment is in the region of €150 million;

• Two design-build lots, worth a total of around €570 million1, for Companhia de Transmissão de Energia Elétrica Paulista (CTEEP):

• o Lot 1, with a total length of 1,092 km and three new substations in the states of Minas Gerais and Bahia;

• o Lot 7, 507 km long, plus a new substation in the states of Minas Gerais and Rio de Janeiro.

These projects will strengthen the transmission of carbon-free energy from future production plants (photovoltaic farms and onshore wind farms, located in eastern Brazil) and boost the capacity of the national electricity grid.

Cobra IS has built more than 32,000 km of power lines in Brazil over the past twenty years.
