The onshore wind energy has been growing rapidly in recent years and has reached a share of 9% in the Brazilian energy matrix. Although there is no offshore wind installation in Brazil, research has shown a large and unexplored energy potential in the country. The aim of this study is to perform an economic analysis for offshore wind projects in the Brazilian sea through the CAPEX and LCOE indicators, highlighting the preferred regions from an economic and energy view. Economic indicators were calculated considering a bathymetric limit up to 50 m and the whole extension of the Brazilian seashore. The results indicate that the Northeast region of the Brazil, especially between Maranhão and Rio Grande do Norte states, has a lower Levelized Cost of Energy, around US$ 69.9/MWh, and Capital Expenditure around of MM US$ 2.34/MW. Other less promising, but still reasonable points for the deployment of offshore wind farms are the ones between the north of the Rio de Janeiro state and the south of the Espírito Santo state, as well as between Santa Catarina and Rio Grande do Sul states.

近年来，陆上风能发展迅速，在巴西能源矩阵中已占9％的份额。尽管巴西没有海上风电装置，但研究表明该国具有巨大且尚未开发的能源潜力。这项研究的目的是通过CAPEX和LCOE指标对巴西海上的海上风能项目进行经济分析，从经济和能源角度突出重点地区。计算经济指标时要考虑到长达50 m的测深限制以及整个巴西海岸的延伸。结果表明，巴西的东北地区，尤其是马拉尼昂州和北里奥格兰德州之间，具有较低的平均能源成本，约为69.9美元/兆瓦时，资本支出约为2.34美元/兆瓦时。其他不太有前途的
