ABB says it has won an order worth around $55 million to supply three new substations and transmission infrastructure for the Brazilian utility Eolicas do Sul.
ABB will design, supply, install and commission the substations in the southern state of Rio Grande do Sul, bordering Uruguay. The project scope includes two turnkey 34.5/138 kV substations, one 138/500 kV substation, step-up power transformers and air- and gas-insulated switchgear. ABB will also supply SCADA and telecommunication systems as well as IEC 61850-compliant substation automation, control and protection equipment. Step-up transformers will increase the voltage of wind-generated power for integration into the transmission grid, ABB says.
ABB will also supply and install two 138 kV overhead transmission lines to connect a new 400 MW wind power plant, one of the largest in the country, to the national electricity grid. The project is scheduled for completion by 2014.
Brazil has traditionally relied heavily on hydropower for its electricity supply. This project is part of the government's efforts to increase the share of wind power as part of its renewable energy portfolio ABB says. Brazil has added significant wind power in the past few years and currently has over 1.5 GW of installed wind capacity, with another 7,000 MW in the pipeline over the next five years.
According to ABB, Brazil is the largest consumer of electricity in Latin America – using twice as much as its neighbors Argentina, Chile and Uruguay. The country's installed capacity is just over 100 GW, which is comparable to Italy or the U.K.
