Energy generation from wind projects in Brazil has registered strong growth in recent years. The installed capacity of wind farms in Brazil reached 14.8 GW in April 2019, distributed among 587 wind farms. Brazil’s electricity grid is expected to have 26.7 GW of wind power generation capacity by the end of 2027¹.
Energy generation by wind farms varies mainly according to average wind speed. In the Northeastern and Southern regions of Brazil, wind farms generate less energy in the first and second quarters of the year due to lower average wind speed, compared to the third and fourth quarters. Revenue of wind farms depends on the agreement and may be based on effective generation or seasonal adjustment.
Note that each wind farm has its capacity factor defined according to a certificate issued by independent specialized companies, mainly based on the characteristics of the wind measured in the region and the specific characteristics of each project. The volume of energy that can be traded in wind projects is based on their certified generation potential. Furthermore, a wind project is only allowed to sell its energy through regulated energy auctions if the measurement of capacity factor considers wind measurements of at least three years. Hence, the efficiency of wind farms can be measured by comparing the certified capacity factor and effective generation by the asset, considering the generation during 12-month periods, which is the time frame required to eliminate any effects of seasonal variations in winds during the year.
